I did a network reset but it didnt solve a problem. I didnt do factory reset yet. I’m little aprehensive doing that. It might not help and i might loose some data. There is no guarantee that it will help right?
Please confirm that you still have data to use. Log into My Account / My Data & Add-ons to see how much has been consumed...if you see none, that's indicating that its been used up until next renewal. You can also consider a data add-on (1GB / $15) to carry you over if your data has been exhausted already.
