Change APN settings
If after your unlock, you can't get data, then you should confirm the new network APN settings.
APN stands for "Access Point Name", and it is the configuration you need to do if after the unlock you can't get 3G or any data connection.
To change it (the easy way), you can log on to unlockit.co.nz from your phone and install the correct APN for the new network.
Unlockit is free and user based, so even if your new network is not available, you can create it and share it with the community.
Other way to do it, if your provider allows it, is tapping and changing the fields directly.
You can do it by;
- iPhone: Settings > General > Network > Cellular Data Network
- iPad: Settings > Cellular Data > APN Settings
