Losing signal when mobile data is on

[Rick Lim]

I've had the Nexus 4 for about a month now and i haven't had a problem until this yesterday. When i turn on my mobile data, i lose my signal. It just stops working. My phone then just becomes useless. The Wi-Fi still works fine and is the only way i can connect to the internet on my phone. Anyone know what to do to fix this? I'm on Andriod 4.3. Tried reboots and airplane mode. Nothing. Any help would be greatly appreciated

Have you checked with the cell service company? Maybe they are having issues

Go to Settings -> More... -> Mobile Networks -> Access Point Names. What is listed there? Tap on the T-Mobile entry; what are the current settings?


Mobile data will not work without a valid APN configuration.

...
APN type: Default, suppl, mms
...

The only thing which catches my eye (and it is probably just a typo here) is that there should not be any spaces in the line above. "default,suppl,mms" - no spaces, no caps, and of course, no quotes.

If you do make any changes, be sure to save the APN (menu -> Save) and then reboot the phone.

If you reset everything to default (ie. factory default) and the APN settings are correct, I think it's time to contact T-Mobile.

Re: Nexus 4 Signal HELP

The "Default" APN settings are not necessarily the correct settings. Your settings as you listed them above were correct for T-Mobile with the exception of the improper spaces as I already mentioned.

Having said that, I don't think the problem is with your phone but with T-Mobile. Where are you located? Are you sure you actually have a data plan with your T-Mobile account? What is your data limit? Is it possible you have gone over the limit for the current billing period?

yaahh, i just had a typo. Without spaces is whats actually on the phone.
Im in NYC and yeah i have a data plan with T-Mobile. Its that unlimited data for like 200 mb till it crawls.

Re: Nexus 4 Signal HELP

Go to Settings>About phone and see if you have anything under Baseband version. Next tap Status and see if you have an IMEI number listed and if it shows your phone number under My phone number.

Re: Nexus 4 Signal HELP

PS: Don't post your IMEI number; just tell us if it is there. Should be 15 digits, I believe.

You can also view the IMEI number by opening the phone app and dialing *#06#.

Re: Nexus 4 Signal HELP

So when my brother called T-Mobile and he asked why my phone couldnt go on the internet, they said they "cut" my internet off because i was using "too much". Which makes no sense since i have unlimited data. I think they were just too lazy to check the problem and just made up an excuse. They then convenanitely asked me to increase the amunt of high speed data I have but we declined. I think the problem is the phone itself. I'm on Android 4.3 and i think maybe i should downgrade to 4.2.2. Anyway i can do that without losing all the stuff on my phone? or should i just wait until Android 4.4?

Re: Nexus 4 Signal HELP

What they probably meant was that you used your allotment of full-speed data (did you say 200mb?) and you are now limited to Edge speeds for the remainder of your billing period. Edge speed is, for all intents and purposes, as close to zero as you can get without actually hitting zero. In other words, slow. Caterpillar slow. Snail slow. So slow, a single simple webpage may take many minutes to download.

Yeah I know that, they said they "cut" off my internet. I've been using the plan for a while now, the internet speed doesnt bother me that much. Now i cant go on at all. They take a few seconds but i juustu gotta wait. Yeah 200 MB, got an answer for the should i wait for 4.3 or downgrade.
