If your phone or SIM card is lost or stolen and automatic recharge is on, this could be a serious problem.

To prevent this, log in to your account and activate the option to block your service immediately after you notice your phone or SIM card is missing. You can find this option in the My SIM Cards menu. Your OneSimCard service for this SIM card number will be instantly blocked. The remaining balance on your lost SIM can be transferred to another SIM card on your account or you can order a replacement SIM card if you would like to keep your phone numbers from the lost SIM. However, the existing data package can’t be transferred to the new SIM card.

Alternatively, you can contact customer service online or call 001-617-313-8888 for assistance.

Some recent Android upgrades to versions 4.2.1 and 4.2.2 have a bug causing the OneSimCard Menu, labeled as SIM Toolkit, to be disabled.

If you do not see the SIM Toolkit app in your Android phone, please try doing the following:

Go to Settings>Security>Other Security Settings>Setup SIM Card Lock>Lock SIM Card. It will ask for the default SIM PIN. Enter 0000. Power off the phone and turn it back on. The SIM Toolkit app will then become available, though it might take 1-2 minutes for the phone to display it.

On Android version 5.1 go to Settings > SIM Cards > SIM Toolkit

Once you have access to the SIM Toolkit, select it, scroll down to Settings, enter 1101 and press confirm. Your phone will now be able to dial normally.

For eSIM cards, make certain that your eSIM is enabled.

 

Yes. Your Universal, Expedition and eSIM World OneSimCard mobile number can currently be forwarded to EU, Canada, USA, Russia, Ukraine and Belarus numbers. It's 100% free to forward your OneSimCard phone number to many countries including to U.S. or Canadian numbers. Forwarding to some countries, as well as to satellite phones, will carry a forwarding charge as listed in the Rates & Coverage page on OneSimCard.com.

To enable/disable call forwarding from your online account:

Log in at OneSimCard.com and go to the My SIM Cards menu. Select your SIM card number and enable/disable Call Forwarding on this screen.

To enable/disable call forwarding from your phone:

Dial *146*081*XXXXXXXXXXXXX# and press Send/Talk (where XXXXXXXXXXXXX is the forward-to number in international format: 00+countrycode+number)

Newer SIM cards use *81* instead of *081*

Example: to forward to U.S. number 1-617-555-1212, dial *146*081*0016175551212# and press Send/Talk.

If you get an "Unknown Format?" message, dial *146*81*0016175551212#

To disable call forwarding, dial *146*080# and press Send/Talk. If you get an "Unknown Format?" message dial *146*80# and press Send/Talk.

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.
