OneSimCard FAQ

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:

• When dialing in Viber, if Viber user chooses the Estonian country code in the menu then they should just dial 800XXXXXXXX because the +372 is added automatically.
• If the “free calls to OneSimCard from Viber” option is not activated for a particular OneSimCard number, when a Viber user dials +372800XXXXXXXX they will hear an automatic message: “The mobile phone is either switched off or out of coverage area.”

PLEASE NOTE: Viber is not available for the DataMax or DataMax eSIM

The SIM card does not offer SMS service to short code numbers

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:
