How To Fix Sony Xperia Z2 4G LTE Not Working Problem

1. Check if you have entered the correct APN settings for your phone. Different carriers, different smartphones and different connections require different APN settings. To change the APN settings go to Settings > Connectivity > More Networks > Mobile Network > Access Point Names. You can either edit the current APN or create another one.

2. Change the network mode. The network mode basically lets you choose the connectivity type. You can select 2G or EDGE, 3G and of course, 4G. Go to Settings > Connectivity > Mobile Data > Network Mode and select 4G.

3. Make sure you are on a 4G plan. Contact your carrier and see if you are on a 4G or 3G plan. Sometimes, carriers activate the wrong plan and you are stuck with only 3G data.

4. Update the phone to latest firmware version. Go to Settings > About Phone > Update and check if a OTA is available. If not, download and install Sony PC Companion. Connect your phone and click Update or Repair on the software program.

The solutions above will fix the 4G LTE data not working problem on the Sony Xperia Z2. If your phone is still experiencing issues, you should send it back to the store for a control.


  1. Selecting Access Point Name did it for me (Actually did Wireless & Networks > Internet Settings > Accept (which installed the APN for me))

    Thanks, Recently had a shop reset my phone and couldnt figure out why it wasn’t working – Would have thought it would work automatically!

  2. The Android KitKat 4.4.2 update that Sony rolled out eliminated the presence of an “LTE” icon in the phone’s firmware. There is absolutely nothing you can do to get it to say “LTE.” It will say “4G”
    I have all my settings correct, and I get 1 bar of 4G on my Z2 while my friends standing right next to me with Galaxy S5s and iPhones get full 4G/LTE bars. My data speed is 1/4 that of the S5 and the iPhone.

  3. Below steps worked for us => Settings > Wireless & Networks > Internet Settings > Accept (which installed the APN for me).
