Discount SMS from Europe and many other countries are available with OneSimCard Universal, OneSimCard Plus, Expedition (formerly Data & Roam) and Europe & More SIM cards.

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. On Apple devices from OneSimCard Assist app

3. From OneSimCard mobile phone: 

     Dial the following: *146*942#

 

The remaining data balance will be displayed.

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 30c per session, however in Europe and elsewhere it can be as little as 1c. Check all rates.

Please note: Some phones, like iPhones 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 or disabling GPRS from your OneSimCard account if you will not be needing data service. By default, all SIM cards are pre-programmed with GPRS data service disabled.

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:

 Problem with Receiving SMS:

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 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.

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.

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 US wireless carrier for assistance if needed.
