DataMax SIM cards can't be managed by myOneSim app at this time

Some recent Android upgrades to versions 4.2.1 and 4.2.2 have a bug causing the OneSimCard Menu, labeled as SIM Toolkit, to be disabled.

If you do not see the SIM Toolkit app in your Android phone, please try doing the following:

Go to Settings>Security>Other Security Settings>Setup SIM Card Lock>Lock SIM Card. It will ask for the default SIM PIN. Enter 0000. Power off the phone and turn it back on. The SIM Toolkit app will then become available, though it might take 1-2 minutes for the phone to display it.

On Android version 5.1 go to Settings > SIM Cards > SIM Toolkit

Once you have access to the SIM Toolkit, select it, scroll down to Settings, enter 1101 and press confirm. Your phone will now be able to dial normally.

For eSIM cards, make certain that your eSIM is enabled.

There are three ways to check the remaining balance of purchased data plan.

1. On-line in the Discount Section of the My SIM Cards menu of your web account or in the mini account at https://ma.onesimcard.com/ 

2. For eSIMs from the OneSim eSIM app

3. From OneSimCard mobile phone (for Universal, Expedition and eSIM World SIM cards only): 

     Dial the following: *146*942#

The remaining data balance will be displayed.

Direct Dial calling allows the caller to enter the international  call prefix, country calling code and telephone number and then be directly connected to the person they are calling. This is how you dial when using your regular mobile service. Direct Dial Calling is standard on the OneSimCard Europe & More, OneSimCard Universal and eSIM.

Callback calling also allows the caller to enter the international  call prefix, country calling code and telephone number. After the called number is entered, the user immediately receives an incoming call connecting the user to person called. Callback is very simple to use and allows for low cost calling on the OneSimCard Plus and OneSimCard Expedition (formerly Data & Roam). Callback does not increase the connection time. It is the same as with Direct Dial.

This answer applies to SIM cards purchased before January 1, 2017.

Some phones, such as Samsung, some Motorola, Android and Apple iPhones, require special dialing instructions or simple OneSimCard settings menu changes in order to make calls.

It is possible to make almost any phone entirely compatible, so you can call directly without using the OneSimCard menu or *146* by following these simple programming instructions below.

How to activate compatibility mode:

  1. Locate OneSimCard Menu.

 On iPhones it is called SIM Applications menu and is located under Settings- Phone menu

         On Androids it is called SIM Toolkit app or OneSimCard app and it looks like one of the apps.

2. Open "OneSimCard" menu ( SIM Applications, SIM Toolkit, STK)
3. Select "Settings

4. Agree with message by pressing "Yes"
5. Dial digits "1101" and select "OK" (Screen will show "CC OptionX: ON" message)

Bear in mind that if you have powered your telephone down, and have removed and reinstalled the battery, you will need to follow the programming steps outlined above, again.

If for any reason after entering compatibility code, you still do not get a ringback or you get the ringback the first time you make a call, but second time it would not work, please enter code 802 into the Service Code window instead of 1101 as provided above.

iPhone users can download OneSimCard Assist App from iTunes that will takes care of the iphones compatibility issues, except for removing the ringback.

For example, calling to USA: Dial *146*0016175551212# and press the TALK (or SEND) button

• To check your balance dial  *146*099# and press the TALK (or SEND) button
• To add funds dial *146*098XXXX*ZZ# and press the TALK (or SEND) button,
  where XXXX - 4 last digit of your credit card on file, ZZ - Recharge amount
• You need to press * on your phone in the above dialing sequences
• Activation of voice mail *146*091# and press the TALK (or SEND) button
• Deactivation of voice mail *146*090# and press the TALK (or SEND) button
• Check number of messages in Voice Mail *146*094# and press the TALK (or SEND) button
• To listen to voice mail *146*095# and press the TALK (or SEND) button

The sequence *146* and # at the end can be used from any phone. However, most phones do not require it.

We strongly recommend you to watch very short video tutorials that will help you to understand how to make calls, SMS and data on your OneSimCard Phone.

If your phone or SIM card is lost or stolen and automatic recharge is on, this could be a serious problem.

To prevent this, log in to your account and activate the option to block your service immediately after you notice your phone or SIM card is missing. You can find this option in the My SIM Cards menu. Your OneSimCard service for this SIM card number will be instantly blocked. The remaining balance on your lost SIM can be transferred to another SIM card on your account or you can order a replacement SIM card if you would like to keep your phone numbers from the lost SIM. However, the existing data package can’t be transferred to the new SIM card.

Alternatively, you can contact customer service online or call 001-617-313-8888 for assistance.

• To check your balance dial  *146*099 and press the TALK (or SEND) button
• To add funds dial *146*098XXXX*ZZ and press the TALK (or SEND) button,
  where XXXX - 4 last digit of your credit card on file, ZZ - Recharge amount
• You need to press * on your phone in the above dialing sequences
• Activation of voice mail *146*091 and press the TALK (or SEND) button
• Deactivation of voice mail *146*090 and press the TALK (or SEND) button
• Check number of messages in Voice Mail *146*094 and press the TALK (or SEND) button
• To listen to voice mail *146*095 and press the TALK (or SEND) button

How to activate compatibility mode:

  1. Locate and Open "OneSimCard" Menu. ( It could  be displayed as STK Menu)

        2. Select "Settings"

3. Agree with message by pressing "Yes"
4. Dial digits "1101" and select "OK" (Screen will show "CC OptionX: ON" message)

Bear in mind that if you have powered your telephone down, and have removed and reinstalled the battery, you will need to follow the programming steps outlined above, again.
d when used with a OneSimCard.

Some phone models do not allow direct dialing with older OneSimCard SIMs sold before January 1, 2017.

To get around this problem, you should try either of these methods:

• Locate the OneSimCard menu on your phone. (Some phones have it in Applications.)
  Make a call using menu 'Call'.
• You can also make a call by dialing directly *146*00 Country Code Number#
  For example, to make a call to the USA, you would dial *146*0018574440686# (do not forget to hit pound at the end of the number)

* is a star character located on the keypad

Other examples of how to use the *146* dialing prefix if necessary:

• To check your balance dial  *146*099# and press the TALK (or SEND) button
• To add funds dial *146*098XXXX*ZZ# and press the TALK (or SEND) button,
  where XXXX - 4 last digit of your credit card on file, ZZ - Recharge amount
• You need to press * on your phone in the above dialing sequences (it is a star character located on the keypad)
• Activation of voice mail *146*091# and press the TALK (or SEND) button
• Deactivation of voice mail *146*090# and press the TALK (or SEND) button
• Check number of messages in Voice Mail *146*094# and press the TALK (or SEND) button
• To listen to voice mail *146*095# and press the TALK (or SEND) button

The prefix *146* and # at the end can be used from any phone. However, newer OneSimCard SIM do not require it and you should be able to dial codes directly, 091, 094, 095, 099 or 098XXXX*XX Talk.

If you have an older SIM and the dialing does not work without entering *146*, please follow these simple instructions to remove the need to dial *146*:

How to activate compatibility mode:

 1. Locate OneSimCard Menu.

 On iPhones it is called SIM Applications menu and is located under Settings- Phone menu

         On Androids it is called SIM Toolkit app and it looks like one of the apps

1. Open "OneSimCard" menu ( SIM Applications, SIM Toolkit, STK)
2. Select "Settings

Newer SIM Cards: Select Compatibility option and make sure "On" is selected

Older SIM Cards: After selecting Settings:

1. Agree with message by pressing "Yes"
2. Dial digits "1101" and select "OK" (Screen will show "CC OptionX: ON" message)

Bear in mind that if you have powered your telephone down, and have removed and reinstalled the battery, you will need to follow the programming steps outlined above, again.

When dialed directly, some Nokia and other phones can display message: "Call is not allowed" or "Call is barred". Just ignore this message and wait for the ring-back for 10 seconds or so.

Local carriers in Saudi Arabia sometimes block standard OneSimCard outgoing calls. If this happens you need to either (a) enter a compatibility code into the settings of your phone or (b) initiate your call by sending an SMS message from the regular SMS menu (not the OneSimCard menu) of your phone.

How To Activate Compatibility Mode:

0. Open "OneSimCard" menu
0. Select "Settings"
0. Agree with message by pressing "Yes"
0. Dial digits "802" and select "OK" (screen will show message "output channel is SMS")

Bear in mind that if you have powered your telephone down and removed and reinstalled the battery, you will need to follow the programming steps outlined above again.

How To Deactivate Compatibility Mode:

0. Open "OneSimCard" menu
0. Select "Settings"
0. Agree with message by pressing "Yes"
0. Dial digits "801" and select "OK" (screen will show message "output channel is USSD")

How To Dial Without Activating Compatibility Mode:

Initiate your call by sending an SMS message from the regular SMS menu (not the OneSimCard menu) of your phone.

For example, to call from Saudi Arabia to Boston USA you should go to the SMS menu of the phone and send a message:

There are no special instructions to receive calls in these countries.

Yes. To reduce fraud and to protect you from over-spending, there is 30-day credit card spending limit set for each individual account. You will only be able to charge up to a certain amount during any 30-day period. You can see your current limit by logging in to your OneSimCard account and going to the Purchase History menu. There, you will find a Credit Card Authorization form available for download. If you would like to increase your monthly credit card spending limit, please download the Authorization form and submit it back to OneSimCard as instructed on the form.

There can be a number of reasons why a battery does not hold a charge. Excluding the possibility of it being a faulty battery, there is another important factor to consider. If your phone is not registered on a roaming network, the battery will drain very quickly as the phone is constantly searching for a network to register on. So, if you get on a 6 hour flight and do not turn the phone off, or put it into airplane mode, by the time you land at the airport your battery will be drained and you will not be able to call back home.

The same thing will happen in those areas with spotty or weak signal network coverage - the battery will drain very fast. It is always a good idea to have an extra battery with you when you travel abroad.

SMS messaging usually works without any additional setup of the phone.
In rare cases when there are issues sending or receiving text messages, please look at the following:

Problem with Sending SMS:

• Incorrect SMSC number (SMS Service Center Address) in handset settings.

SMSC number should be set as follows:

1. For Standard  and Plus OneSimCard SIM: +3725099000 for all countries except:

a. China:  +85290296747

2. For the Expedition (former Data & Roam) SIM as well as for Europe & More SIM: +37256100041

Special instructions for Apple Phones:

With Apple iPhones to check SMSC:

From the phone dialer Dial *#5005*7672# 

You will see the SMSC set currently on the phone. 

To change the SMSC on Iphone dial: 

Plus and Standard SIMs: **5005*7672*+3725099000# for all countries except China and **5005*7672*+85290296747# if in China.

Expedition (formerly Data & Roam) and Europe & More SIMs in any country: **5005*7672*+37256100041#

• NOTE: It is important to have the "+" symbol entered in front of the SMSC number.
• You can find locations of the Message Settings menus for different phone models here.

If your phone requires the name of Message Center Name enter: SMSC
SMS lifetime is short - must be at least 2 hours or set to Maximum settings.
Try sending SMS from OneSimCard menu

 Problem with Receiving SMS:

• Receiving Handset does not have enough free memory for incoming SMS.
• Receiving Handset was turned off or out of the coverage area during SMS lifetime set on the sending phone - usually 2 hours.
• Sender's SMS provider does not have an agreement with the receiving network.

Sometimes when moving from the USA, Canada or Mexico to another country, the SIM card will need to be reset to properly register on a new country roaming network.

• If you have the OneSimCard Menu on your phone (it may be called Sim Application Menu on iPhones or SIM Toolkit on Androids), go to the menu, scroll down to Settings and enter Service Code 2003 and confirm, then Code 000 and confirm. For older SIM cards after this enter Service Code 1101 and confirm. Turn the phone off and then back on. 
  
  
• If you do not have access to the OneSimCard Menu then turn off your phone, remove the battery for 20 seconds, reinstall the battery and then turn back on your phone.

Some recent Android upgrades to versions 4.2.1 and 4.2.2 have a bug causing the OneSimCard Menu, labeled as SIM Toolkit, to be disabled.

If you do not see the SIM Toolkit app in your Android phone, please try doing the following:

Go to Settings>Security>Other Security Settings>Setup SIM Card Lock>Lock SIM Card. It will ask for the default SIM PIN. Enter 0000. Power off the phone and turn it back on. The SIM Toolkit app will then become available, though it might take 1-2 minutes for the phone to display it.

On Android version 5.1 go to Settings > SIM Cards > SIM Toolkit

Once you have access to the SIM Toolkit, select it, scroll down to Settings, enter 1101 and press confirm. Your phone will now be able to dial normally.

For eSIM cards, make certain that your eSIM is enabled.

There are three ways to check the remaining balance of purchased data plan.

1. On-line in the Discount Section of the My SIM Cards menu of your web account or in the mini account at https://ma.onesimcard.com/ 

2. For eSIMs from the OneSim eSIM app

3. From OneSimCard mobile phone (for Universal, Expedition and eSIM World SIM cards only): 

     Dial the following: *146*942#

The remaining data balance will be displayed.

Yes, you can easily forward calls from your regular cell phone number, home phone, office, etc. to your OneSimCard phone while you're abroad!

Your OneSimCard international Universal and Expedition SIM card comes with both a European and U.S. number. To forward your regular U.S. numbers to the SIM, just set them to forward to the U.S. number that's included with your SIM card. For eSIM World and DataMax eSIM, you can order Personal Extra Numbers (PENs) as needed for an additional cost.

You can also order unlimited Personal Extra Numbers (PEN) - Local or Toll Free - in many different countries, including USA, Canada, UK, France, Italy and Spain. For example, if you work or live in the UK and want to keep receiving calls made to your regular UK numbers, just add a UK PEN to your SIM card and set up call forwarding to that new number.

Calls received through a PEN will be charged an additional 20c/min to the incoming rate of the country you are in. The exception is calls received through a UK-Mobile PEN which is only charged an additional 25c per call.

Please Note: Your subscription to a Personal Extra Number starts the moment your order is shipped. If you do not need your PEN to be active right away, you can always wait and order a PEN later at any time by logging in to your account.

You can forward your calls to your 1SIM VoIP PEN. Simply forward all calls from your phone number to your 1SIM VoIP PEN using the directions below. Normal charges will apply for receiving calls to your 1SIM VoIP number (there will be NO extra $0.20, or $0.25 for UK PEN, cost to receive a call on OneSim VoIP).

Different carriers use different ways of programming call forwarding. Below are instructions to setup call forwarding with various US wireless carriers. We urge you to test the call forwarding a few days prior to your trip, and to call your wireless carrier for assistance if needed.

Alltel, , Verizon Wireless, Cricket Wireless

To activate Call Forwarding:

1. Press *72 on your cellular phone.
2. Enter your ten-digit Second Personal OneSimCard phone number (area code + telephone number).

* is a star character located on the keypad

To deactivate Call Forwarding:

1. Enter *720 on your cellular phone.
2. Press OK/Send (a tone will confirm the deactivation).

T-Mobile and AT&T Wireless GSM phones

The main advantages are significant cost savings and the ability to call from countries where there is no voice roaming coverage available, or for DataMax or DataMax eSIMs

OneSim VoiP can be used from any Android or Apple ( iOS) device to make international LD calls even when you are not traveling. OneSim VoIP does not require having OneSimCard SIM being installed in the phone. OneSim VoIP can be used with Wi-Fi or 3G/4G - no difference. You just need to have OneSimCard account with the SIM VoIP capable PEN. Calling using OneSim VoIP will cost most of the time less than any other way of calling.

OneSimCard VoIP requires you to order a compatible Personal Extra Number (PEN). Most of the PENs we offer are OneSim VoIP enabled. You also need to have an Android phone with software version 8 or higher, or Apple device (iPhone, iPad, iPod Touch) with iOS 6.1 or higher.

Once you have an active OneSim VoIP enabled PEN, you will be able to see the option to create a OneSim VoIP account in the My SIM Cards menu of your online account.

To make an outgoing call using OneSim VoIP, you need to be registered on a Wi-Fi network and have the OneSim VoIP app running on your phone. You should make the call using the OneSim VoIP app dial pad. To make a call the regular roaming way,you should make a call from your regular phone dial pad. 

NOTE: Regular roaming calling is NOT available on DataMax or DataMax eSIM cards. To use voice you will need to use the OneSim VoIP app

Yes. If you are not available to answer the OneSim VoIP call or if the OneSim VoIP app is turned off, the call will be routed through our standard roaming network. If the call is not answered it will be sent to your OneSimCard voicemail box. 

NOTE: Voicemail is not available for DataMax or DataMax eSIM cards with OneSim VoIP.

In countries where the cost of using mobile Internet Data is below 20 c/MB, the cost of using SIM VoIP over the data is comparable or less than the actual calling rate from the country.

As a rule of thumb, the SIM VoIP will use 1MB /Min of talk time. So, if the cost of Data in the country is 10 c/MB, then 1 minute SIM VoIP call will cost you 12 cents /minute. You need to have a 3G connection in order for SIM VoIP to work this way. 

OneSimCard SIM VoIP users with US and Canadian numbers may now send and receive text messages over the OneSim VoIP app on iPhone and Android. The cost to sending a message is $0.05 per text to most countries. Receiving message is $0.05.  

OneSimCard M2M SIM Card offers Internet Data and SMS Service. Voice is not available. If you require Voice, please consider buying Expedition or Universal SIM at www.OneSimCard.com

OneSimCard M2M SIM works on major networks of the countries where it is being used.

For example in USA the service is offered on AT&T, & T-Mobile networks. In Canada the service is offered on Rogers, Telus or Bell Canada. The switching between networks is automatic. The networks with the strongest signal will be selected to provide the best quality of service.

Yes, all usage details and charges are available in the My SIM Card menu of the customer account.

In addition, you can filter SIM cards using the following parameters:

• SIM cards with Data Package to be activated when the traffic starts moving
  • This option allows you to view those SIM cards where data packages have been set up for activation and will be triggered automatically once data is moving on the SIM.


• SIM cards with data packages scheduled to get activated later
  • This option displays SIM cards with data packages scheduled to be activated on a particular date.


• SIM with the balance below X
  • This option displays SIM cards with low balances that might need your attention to ensure service is not interrupted due to lack of funds.


• SIM cards with the data usage over the last X DAYS above Y MB
  • This option displays SIM cards with the data usage exceeding your projected usage or could be used for other usage monitoring applications.


• SIM Cards with the $ spending – Top X % in 30 days
  • This option displays SIM cards that are consuming the most funds for data and SMS usage.


• SIM cards that reached monthly additions limit
  • If monthly spending limits for SIM cards are set, this option allows you to view SIM cards that already reached the monthly limit and are temporarily not in service until additional funds are added.


• SIM cards 10% below monthly additions limit
  • This option allows you to view the range of SIM cards that are about to reach the monthly limit (If you have set limits on the SIM cards.)

•  
  • Do you offer an eSIM option for iPhones, Androids or Tablets?

Yes. The OneSimCard eSIM option is available for use with iOS and Android phones, smart watches and even Windows tablets.

eSIM is not a physical SIM, but rather a program that can be downloaded to eSIM compatible phones and device.

Yes, as of March 3rd, 2020, OneSimCard eSIM can be used for Mobile Data, Voice and Texts. However, you can still use the OneSim VOIP app option with a Personal Extra Number (PEN) for additional savings on calling and texting

For DataMax eSIMs, only Data is available. However, you can use our OneSim VoIP app for cost effective voice and SMS communication.

Yes. Data Roaming should be enabled on your phone for eSIM for data to work. Calls and texts on eSIM World should work with or without it.

There are two ways you can do this:

1. For eSIM World you can use the 1SIM eSIM app.
2. From your mobile go to ma.onesimcard.com. This provides the access to your free  OneSimCard mini account. Free means that there is no need to have the SIM balance or data package on the SIM to be able to access this page in over 110 countries. Log in to your account and activate a new data package.
   
   2. From any computer log in to your on-line account at OneSimCard.com to order a data package. 

Simply go onto your web account or eSIM app and purchase a new data package appropriate to your travel needs.

Before purchasing, please ensure you have verified that your device is unlocked and one of the supported devices. Installation is completed by using your phone to scan the QR code of the purchased eSIM.  You may scan the QR code by displaying it on the computer screen, another device, or a printed copy.

If you’ve already purchased OneSimCard eSIM, you can see full installation instructions and access your QR code from the Recharge menu in your online account. Make sure eSIM is selected in the Select SIM Card drop down menu.
