If your phone accepted the code received from us but you do not have data connection (only calling and testing) there is a problem with your APN settings.

You have to configure the new APN settings of your phone. Basically the APN settings are very similar to the internet settings of a typical computer and contains the address of a proxy, an user and a password.

As you can imagine each carrier has unique settings. Please consult your phone manual for more information. In order to get the new correct APN settings you can call its call center, look on the internet or go to the closest carrier store and they will set up your phone for free.
