A new email came via The Droid Guy Mailbag about a problem wherein Nexus 5 can’t connect to data. The message says, “I have my data enabled in my Nexus 5 and I can send/receive calls/texts, but I cannot use any app that requires cellular data. However, my phone works just fine over Wi-Fi. Also a notification pops up constantly saying ‘Sign Into T-Mobile Network’ and when I click it, it goes to a site. Since my data isn’t working, the page is blank and says ‘server error’ or something. I’ve had this problem for a while now and have tried everything I can possibly think of. I’ve deleted the APNs, put them back in, disabled/re-enable data, factory reset, cleared caches, changed SIM cards, gone back to stock, re-rooted, changed ROMs (like 5 times), and called T-Mobile but they haven’t provided me any solution that worked! I’d really appreciate the help. Thank you.”
Possible Reason of the Nexus 5 Can’t Connect to Data Issue
If even Factory Reset fails to solve the problem, then, it might be an issue in the hardware itself.
In the Support section of the T-Mobile site, a contributor who claimed to be an employee of the company revealed that the problem where the Nexus 5 won’t connect to data has been plaguing T-Mobile subscribers for quite some time now.
She said that the company is currently working to arrive at a fix for the issue. However, she added that the company suspects that the issue might also stem from the device itself or on the end of Google.
If this is the case, the only probable solution for this is wait for an OTA update from your carrier that contains a fix and then install it, since you cannot return the device already due to the fact that you have rooted it repeatedly—which voids its warranty.
