Verizon and Sprint now offer dual mode - CDMA and GSM phones, which are capable of working on GSM networks. You can request Verizon and Sprint to unlock the GSM portion of the phone for international travel and they will most likely do this for you. However, Verizon and Sprint usually does not unlock phones 100% - they do this partially, so you are not able to use the phone while in USA.

In such Verizon and Sprint phones you can get invalid message when inserting OneSimCard SIM or your phone does not find US networks. Verizon and Sprint unlock their phones in such a way that you can't use it in USA, but once you are out of the country the SIM will be accepted. Unfortunately, there is no way to tell the difference with this kind of unlocking if the phone is not unlocked or partially unlocked to work only outside of USA. In our experience, once this kind of phone leaves USA, it starts working.

To make an outgoing call you may need to do the following:

Initiate your call by sending a free SMS message from the regular SMS menu (not the OneSimCard Menu) of a OneSimCard enabled phone:

For example, to call to Boston USA you should go to the SMS menu of the phone and send a message:

Please Note:

1. You can not send this SMS from the SMS OneSimCard Menu of the phone, it must be sent using your phone's standard SMS function. You will not be charged for sending this SMS to 9146.

2. If you see on the screen that the message has not been sent, make sure that the SMS settings of your phone are correct and that the SMS Center number is set to: +3725099000

It depends on the country you're in when making the call. In many countries there is a special low rate of just $0.25/min to call another OneSimCard phone (only when dialing the other OneSimCard user's primary mobile number, not a Personal Extra Number). In other countries your cost will be our standard low outgoing call rate from that country.

Example 1: two OneSimCard users are in Italy and one calls the other, the cost will be $0.25/min for the caller and free for the receiver.


Visit our Rates & Coverage page and choose any country to view its current rates. Use the dropdown menus to see rates for calling to/from other countries.

OneSimCard will work with almost any unlocked GSM tri-band or quad-band cell phone. A partial list of compatible cell phones that we have tested can be viewed here.

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

If your phone is not a quad-band phone, please make sure that the bands of your phone are those required in the country of your travel. You can look it up here.

If you are still unsure whether your cell phone is compatible, contact support or purchase an international cell phone and SIM card bundle from us, which all come preloaded with our international SIM card, $10 balance and All in One International Travel Adapter Plug.
