You can look for the APN settings option in your phone's settings and make sure to fill in the correct APN information.

3.Data limits or delinquent payments: If you have a data limit on your phone** or if your mobile account is in arrears, it may cause your internet connection to fail. You can check if your ** has a data limit and make sure your mobile account has been topped up.
