To determine if your phone is locked, if you haven't already purchased a OneSimCard international SIM card then call your wireless provider. If you have already purchased from us then insert the OneSimCard SIM card. If you get any of the following messages on your screen after entering the pin then your phone is locked:

• Insert SIM
• SIM not valid
• SIM Card Not Accepted
• Enter Restriction Code
• Enter Special Code
• Enter Subsidy Code
• Enter Subsidy Password
• Contact Service Provider (Motorola)
• or any other similar messages!

Some mobile phone carriers lock their phones so they can't be used with other carriers. The simplest way to find out if the phone is locked is to borrow a SIM card from anybody who is using a different mobile service provider. If you power-up the phone and it recognizes the SIM card, your phone is unlocked and OneSimCard's international SIM card will work as well.

If you need to unlock the phone, we suggest contacting your carrier or phone manufacturer for unlocking information or services.

US Customers can read more about unlocking phones in this article of the Computer World magazine.

 

 

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.

2. If the PEN has a SIM card assigned to it, the SIM card balance rules will apply. To maintain the balance both for the SIM and all PENs assigned to it $25 USD min recharge will be required every 10 months.

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.
