My HTC Trophy is only able to connect to the internet if I am connected to Wi-Fi. Otherwise, I get "You might have lost your cellular data connection". This just started happening a few days ago and I am finally done waiting it out to see if it will fix itself.
I called Verizon technical support who walked me through the following steps:
- Go to Settings > system > cellular, turn off data connection, and turn it back on
- In the same screen, set mode to CDMA
- Clear IE cookies/history
- Dial *288 and go to option 1 to activate
His final step was to do a factory reset. However, because there is no way to back up my SMS messages on my WP7.5 in the year 2013, I am not doing that because I need those texts.
Edit: HaLaBi suggests I add APN settings. Here are the fields available on my phone:
APN User name Password Proxy server/URL Proxy port
I don't see any other fields.
