We are here to help you get answers to your questions about OneSimCard phones and services.
How can I add airtime to my OneSimCard service?
In order to add airtime instantly, simply register a credit card with us on our website.
There are several ways to add airtime to your OneSimCard service.
Automatic Recharge - recommended:
From the phone using your credit card (Universal, Expedition and eSIM World only):
 For example, if you need to add $50 and the last 4 digits of the credit card registered with us is 8654:
You would dial 0988654*50 and press TALK. In few seconds you will get a confirmation message with your new balance.

From the phone using 1SIM Fund:
 a) From the phone dialpad dial 098YYYY*XX. Talk. YYYY -  4 digits PIN you created in 1SIM FUND menu. YY Amount from 25 to 99 USD
 For example, if you need to add $50 and the 1SIM FUND PIN is 8654:
You would dial 0988654*50 and press TALK. In few seconds you will get a confirmation message with your new balance.

From the OneSimCard.com web interface:
If you purchased a recharge PIN from OneSimCard Authorized dealer, you can recharge your account from OneSimCard handset from OneSimCard - Add Credit menu. When the Add Credit menu is selected, enter the 10-digit PIN and press the Talk (Send) button.Â
What is time validity of OneSimCard SIM?
All SIM types are valid for 1 year after the last billable use - phone call, sent SMS or data use.
The SIM balance for all types of OneSimCard SIMs is valid for 10 months after the last recharge. Each recharge extends the balance for the next 10 months period. If you do not recharge within the 10-month period, any remaining balance will be forfeited.
Â
NOTE: For Physical 3-in-1Â DataMax & DataMax eSIM SIM cards, if the SIM card has no balance, the SIM will expire and be removed from the account after 7 days, unless there is a data package currently active on the SIM (not a future activation). If there is no balance on the SIM and the active data package expires, the SIM will expire 7 days following the expiration of the active data package.
Â
An expired SIM can be restored for a $10.00 restoration fee plus a recharge of at least $25.00.
Â
Is there a monthly or 30-day credit card spending limit for OneSimCard service?
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.
We strongly suggest that you set your monthly credit card limit before going overseas as dealing with the form on the road can be much more difficult.Â
Is there a 911 emergency number in Europe that can be used with OneSimCard service?
Yes, in Europe the emergency number is 112. You can use 112 in Europe to report real emergencies to local authorities in the country of stay. The 3 digit number should be dialed directly without any additional digits in front of the number.
Â
For DataMax and DataMax eSIM SIM cards, while there is no voice calling feature without the use of 1SIM VoIP, which doesn’t support emergency calling, most cell phones ALWAYS allow you to call emergency numbers, even without a SIM inserted into the phone. In Europe the emergency number is 112. You can use 112 in Europe to report real emergencies to local authorities in the country of stay. The 3 digit number should be dialed directly using the regular phone app (NOT the OneSim VoIP App) without any additional digits in front of the number.

      http://www.onesimcard.com/international-cell-phones/
You can purchase a MI-FI device with aOneSimCard SIM card (Universal, Expedition or DataMax physical SIM card) at http://www.onesimcard.com/international-cell-phones/.

The OneSimCard Money Fund allows you to pay for OneSimCard services by means other than credit cards and also by Visa and Master Cards enrolled in the credit card security programs:
Â
Once you deposit money into your OneSimCard Money Fund through one of above methods, you can use this fund to recharge your SIM(s), order a second number, or make any other payment for orders placed at OneSimCard.com.
OneSimCard Money Fund additions are non-refundable. However, the money you put into the fund does not expire. There are no fees applied to the fund maintenance either.
Example 1
You are in Kenya and can't pay using a credit card. You would like to purchase a OneSimCard SIM for $39.95, and also be able to add airtime (recharge) later. You will also need to pay for shipping.
First step - you need to add funds to your OneSimCard Money Fund. It's up to you what amount you would like to send us, but it should be large enough to cover your purchases. Let's say you posted $200.00 to your OneSimCard Money Fund.
Once the money is received, we will send you a confirmation email. Then you can log in to your OneSimCard.com account and place your order. It will be instantly processed and the money will be deducted from your OneSimCard Money Fund account.
Example 2
You have 3 SIM cards and 3 personal second numbers.
You want to set up auto-recharge for SIM1 and SIM2 in $25 increments and the third one in $50 increments. You also want to extend (recharge) your Second Numbers every month.
Let's say you put $500 into your OneSimCard Money Fund account. Now you can set up $25 auto-recharges on your 2 SIMs and $50 auto-recharge for your 3rd SIM, as well as and automatic extension of your second number.
This option allows many users around the word to take advantage of OneSimCard.com services without using a credit card.
Example 3
You use your credit card account to add money to the 1SIMCard Money Fund. The transaction from a credit cardl is instant. Funds will be instantly added to your 1SIM Card Money Fund, and then you can use the Money Fund to make any purchase at OneSimCard.com.
Â
I used a large amount of data  even though I barely used data, what happened?
Each mobile data session is charged for a minimum of 10kB usage. Even if you check just one 3k email you will be charged for 10kB of usage. In some countries this can be over 30¢ per session, however in Europe and elsewhere it can be as little as 1¢. Check all rates.
 Â
Each mobile data session is charged for a minimum of 100kB usage. Even if you check just one 3k email you will be charged for 100kB of usage.
Please note: Some phones, like iPhones, Androids, and other smartphones, can access data without you even knowing it if you have data enabled. We strongly recommend checking the settings on your phone and disable mobile data roaming if you will not be needing data service. By default, all SIM cards are pre-programmed with data service enabled, once you activate your data package.

Can I keep receiving calls made to my regular cell phone or landline numbers while traveling abroad?
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:Â 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.
