[Q] No 4G/LTE/3G connection

[fabiooli]

I have the D6633 and the phone works great except that it won't connect to the 4G/3G/2G/LTE network. I can make calls, send sms normally. It even recognizes both sim cards connected. But internet only over wi-fi.
I called my operator, they say the phone is configured correctly, I tried my brother's sim card from another operator and the same happens.
So, the phone is clearly unlocked, if not it wouldn't recognize the sim cards at all. But no connection to the internet...
Any suggestions? I already did four factory resets, I recovered the Rom using sony software... Starting to get anxious here

Despite what your operator says, check your phone is configured correctly. Check the APN - copy it from someone else with the same phone on the same network. Which one are you on? Go into the network options and select 4g, or 3g, etc, one at a time. Select the network to connect to manually; you might have a 2g, 3g and 4g connection to chose from; try all of them.

If that fails, especially with what you said about your brother's sim card, it does sound like it's faulty.

Download Internet and MMS. Under settings, More, Internet Settings.

Double check that you have a tick box in Mobile data traffic under settings, More, Mobile Networks

If that doesn't work, then select Mobile networks, Network Operators, note this is quite slow, but should show a list of carriers or bands. Select the one for your sim, which will re-establish with the carrier (and should download the APN's) Access Point Names. If not talk to your operator what these should be and add them if they don't exist (they normally will have info about them on their internet sites.

That worked. I could not configure APN manually, it would not save no matter how many times I configured it. SO I used an APN APP from plaster and it worked. Thank you for the enlightenment!
