FREQUENTLY ASKED QUESTIONS

The OneSimCard phone number has no expiration, provided you made at least 1 call or sent an SMS once every 12 months.

However, the funds on the SIM expire 10 months after your last recharge. The minimum recharge amount is $25. You can keep the balance from expiring by simply recharging at least once every 10 months. If you let your balance expire, then all you need to do to get the service up and running again is to log in and add funds to your SIM card. Automatic recharge will be canceled if you let your funds expire.

NOTE: For Physical 3-in-1 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.

 

An expired SIM can be restored for a $10.00 restoration fee plus a recharge of at least $25.00.

Direct Dial calling allows the caller to enter the international  call prefix, country calling code and telephone number and then be directly connected to the person they are calling. This is how you dial when using your regular mobile service. Direct Dial Calling is standard on the OneSimCard Europe & More, OneSimCard Universal and eSIM.

Callback calling also allows the caller to enter the international  call prefix, country calling code and telephone number. After the called number is entered, the user immediately receives an incoming call connecting the user to person called. Callback is very simple to use and allows for low cost calling on the OneSimCard Plus and OneSimCard Expedition (formerly Data & Roam). Callback does not increase the connection time. It is the same as with Direct Dial.

This answer applies to SIM cards purchased before January 1, 2017.

Some phones, such as Samsung, some Motorola, Android and Apple iPhones, require special dialing instructions or simple OneSimCard settings menu changes in order to make calls.

It is possible to make almost any phone entirely compatible, so you can call directly without using the OneSimCard menu or *146* by following these simple programming instructions below.

How to activate compatibility mode:

  1. Locate OneSimCard Menu.

 On iPhones it is called SIM Applications menu and is located under Settings- Phone menu

         On Androids it is called SIM Toolkit app or OneSimCard app and it looks like one of the apps.

   

2. Open "OneSimCard" menu ( SIM Applications, SIM Toolkit, STK)
3. Select "Settings

4. Agree with message by pressing "Yes"
5. Dial digits "1101" and select "OK" (Screen will show "CC OptionX: ON" message)

Bear in mind that if you have powered your telephone down, and have removed and reinstalled the battery, you will need to follow the programming steps outlined above, again.

If for any reason after entering compatibility code, you still do not get a ringback or you get the ringback the first time you make a call, but second time it would not work, please enter code 802 into the Service Code window instead of 1101 as provided above.

 

iPhone users can download OneSimCard Assist App from iTunes that will takes care of the iphones compatibility issues, except for removing the ringback.

For example, calling to USA: Dial *146*0016175551212# and press the TALK (or SEND) button

• To check your balance dial  *146*099# and press the TALK (or SEND) button
• To add funds dial *146*098XXXX*ZZ# and press the TALK (or SEND) button,
  where XXXX - 4 last digit of your credit card on file, ZZ - Recharge amount
• You need to press * on your phone in the above dialing sequences
• Activation of voice mail *146*091# and press the TALK (or SEND) button
• Deactivation of voice mail *146*090# and press the TALK (or SEND) button
• Check number of messages in Voice Mail *146*094# and press the TALK (or SEND) button
• To listen to voice mail *146*095# and press the TALK (or SEND) button

The sequence *146* and # at the end can be used from any phone. However, most phones do not require it.

We strongly recommend you to watch very short video tutorials that will help you to understand how to make calls, SMS and data on your OneSimCard Phone.
