OneSim VoiP can be used from any Android or Apple ( iOS) device to make international LD calls even when you are not traveling.

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.
OneSim VoIP is available with the following SIM cards: Plus, Expedition (formerly Data & Roam),  Europe & More, DataMax, and DataMax eSIM.When making an outgoing call how do I select which way the call should go: through regular roaming or through OneSim VoIP?

For Universal E, Expedition E, eSIM World E, eSIM Asiania, Plus, Europe & More, & Standard SIM Cards, the international SIM card phone number and account will expire if no outgoing usage is made for 12 months. The outgoing usage could be any of the following: Call made from the phone, SMS sent from the phone or any Data Usage.

The SIM card balance is valid for 10 months. The balance will continuously roll over to the next 10 month period provided that at least $25 is added within 10 months after the last recharge.
If the balance expires, the service can still be used after a new recharge of the SIM card.

Personal Extra Numbers will stay active as long as they have been funded properly and the SIM hasn’t expired.

The SIM card balance is valid for 10 months. The balance will continuously roll over to the next 10-month period provided that at least $25 is added within 10 months after the last recharge.
If the SIM card balance expires, 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).

What is the cost of calling between two OneSim VoIP phones?
Calls between two OneSim VoIP phones are absolutely free.I just activated my SIM card and can't make a successful test call. What's wrong?
If you just activated your SIM card and can not make a test call by following the instructions in the user manual, you will likely just need to power off the phone and power it back on again. The phone should automatically re-register with one of our partner networks. Remember, if you answer the test call when it rings you will be charged for the call.© 2006-2024 Belmont Telecom Inc., DBA OneSimCard.com. All rights reserved
