How do I make a call using OneSimCard global cell phone service?
To make a call:
With Europe & More, Univesal and eSIM World that do not use the callback to make a call, you will just get connected.
With OneSimCard Plus SIM or Expedition (formerly Data & Roam) SIMs:
After pressing the TALK/SEND button you will see a variable message on the screen (for example 'Wait for call') which you can ignore and your phone will ring back in a few seconds. Answer this ring as you normally would answer any incoming call. Your call will then be connected.
If you are unsure about how to properly dial an international number, follow this link for detailed country by country dialing instructions.
For Physical 3-in-1 DataMax, and DataMax eSIM cards, you can place calls using our low cost OneSIM VoIP service. OneSim VoIP costs much less than traditional voice roaming.

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.
Is it free for someone to call my OneSimCard number using Viber?
Through a unique partnership with Viber, your primary OneSimCard number (+372) can be called free of charge for any Viber user! (requires activation and special dialing instructions, see below)
HOW: When this feature is activated, Viber users can call OneSimCard numbers for free by using a special dialing format +372800XXXXXXXX, where XXXXXXXX is the rest of the OneSimCard phone number after 372. For example, a OneSimCard user with the phone number +37212345678 should be called by dialing +37280012345678.
TO ACTIVATE: Log in to your OneSimCard account and go to the My SIM Cards menu. Scroll down to where it says "Incoming Viber Calls" and click Enable to activate this option.
COST: The call is free for the Viber user. The cost of receiving the Viber call is the same as receiving a call through a Personal Extra Number (PEN), i.e. the regular incoming call rate in the country you are in plus 20c/min. In countries with free incoming calls, like Italy or Japan, the cost will be just 20c/min.
PLEASE NOTE:
PLEASE NOTE: Viber is not available for the DataMax or DataMax eSIM
