Xperia Z3 Losing Data Connection

[Bosshawk]

Also on Tmobile US and just started experiencing the issue after the 5.1.1 update. No solution so far.

So this worked for me on Tmobile: Go to APN settings and change the protocol from IP6 to IP4. Seems to be working well now.

I agree that this method works. I am aware that in some places in the city, the signal turns to 2G now. I am guessing there was no 4G/3G connection anyway and the phone used to think there was. Now it works perfectly in 2G.

Thank you for providing the solution. I joined to forum to show you my appreciation.

Bosshawk, thank you very much for the solution!. Changing the APN protocol fixed this problem for me too. I found that using the iPv4/iPv6 setting also works and preserves the capability to use iPv6 addresses.

Ever since the 5.1 update, my phone was chronically losing it's T-Mobile data connection. Sony was of absolutely no help. They had me preform unnecessary hard resets and reinstall the OS. When this failed to solve the problem, they told me I had to send the phone in for service. It was evident that their technical support team really doesn't know much. They're just reading from a list and are absolutely clueless about troubleshooting.

Though T-Mobile provides the APN settings, there is a bug in Sony's coding, which they've failed to identify, that is causing this problem. Very happy with Sony hardware, but the company SUCKS!
