No 4G signal on Thunderbolt

48 hours after getting my Thunderbolt, I have yet to receive a 4G signal. I'm in the Phoenix area and Verizon map coverage says I SHOULD have 4g in my specific location.

The only time I experianced a 4g signal was in the Verizon store when I picked the phone up and had it turned on.

Any suggestions?

I have used an app killer to shut down what I think are unnecessary apps and services. Is there a service that I might have turn off that is required to connect to the 4g signal?

I don't have one yet so I don't know whee the settings are located for it...but I do believe there is a place to turn 4g on and off

There is a setting, but it is not in the normal menus. So the device should be set to search for 4G by default.

Found it, PJNC284 offered this to get to the page to turn on or off 4G.

A toggle would make sense but there isn't one (apparently it's coming "soon" though). One suggestion is to go to the dialer and enter *#*#4636#*#*. Hit Phone Information and scroll down to "Set preferred network type" and change that to CDMA (auto PRL). Use the back softkey to back out to your home screen.

This places the phone only on 3G. So I would make sure it is not set to what PJNC stated.

and being in phoenix, i do suspect it's an issue with your thunderbolt, as the network here is exceptional. when LTE rolled out, the data doctors got a usb modem from verizon and went all over the valley testing it out, with great results. i have yet to see the tbolt in action outside of a verizon store though.

I've been having trouble getting 4G (or even 3G) at home, where the coverage map says I am dead-center in a '4G LTE Coverage Area' I've read in other forums ( http://forum.androidcentral.com/showthread.php?p=745762 ) that this is unfortunately commonly occurring right now. Has anybody spoken to a VZW rep and gotten offical word on why this is happening or when it's expected to be resolved?

Sorry for the blank post, it looks like IE9 and the Community have issues.

FWIW I just got off the phone with Verizon Tech and they confirmed that this is a known problem, as well as the Weather App occasionaly showing an incorrect location. HTC has been notified and is working on a fix, no ETA as to when. So far the only thing that has worked for me is to power the phone off and back on. I have tried switching into/out-of 4G vs. the key sequence above, but this does not seem to do the trick.

Try installing the app called LTE On/Off from the android market, it's free. Then run it, and under the settings, choose LTE only, (should be the last setting on the list). See if that works. I know if I'm in a fringe area, my phone will usually choose 3g first and stay locked on it. Also, you can try doing a restart on your phone. Push and hold the on/off button and choose restart. This will close all running apps and clear your cache. Mine was stuck on 1x and I did this and it worked. Good luck.

Do a master reset, and if it doesn't work contact vzw.

Changing your raido settings is a bandaid fix at best

My 4G worked great until a week ago. Now, when I can get 4G, the phone will not transfer any data until if falls back to 3G. I can stand in the same spot where I amazed my co-workers and watch them get drowsy waiting on a simple web page to load. I called Verizon support twice and went through all of the steps to reset the phone with the network. No help. I understand from some of the Android web sites that this is a known problem as well as GPS not displaying the correct location. There is supposed to be a patch on the way. I am not a very happy owner right now.

4G in my area, but it does not work at my house. The VZW announcement specifically called out my home area, but nothing. Had the phone on over night, and the battery died because it was searching for 4G. Hopefully, it will work at my office. In that case, I will have to manually switch between wifi at home (faster than 3G) and 4G at work. If that works, then I will be happy enough for now. Time will tell.

4G does not work inside my office building either.

Verizon seems to have 4G back on-line

I tried resetting the HTC TBolt after not getting 4G signal and that has solved the problem so far.

gina7289

I heard it is a void of a terms of conditions too do the switch in settings and there blocking switch apps.

PJNC284

Unlikely. Verizon's sales numbers for the Thunderbolt and other 4G devices would be in the tank and return numbers would be through the roof without those apps.

gina7289

I got warned it is not an acceptable way to trouble shoot so I was told not or else. As of April 29th since that was part of the reason it crashed.

gina7289

Mine don't work because when doing the internet it was looking for other things while trying the internet and before the crash the setting was changed to 3g only. Now I still get lower 3g signal but it works. I don't have 4g but it still looks for it especially when powering it up losing 10 - 15 % sometimes.

Didn't I ment

Hello fellow forum members,

Today was the release for the software update for the Thunderbolt. May I have you try to update your software, on 3G if needed, an do a factory reset afterwards. Once done, please retry the 4G data services and reply to this message with a status update.

Hope this helps...

This is how I solved my 4G issue:

Go to the dial pad
Punch in *#*#4636#*#*
Phone Information
(Scroll down to the middle of the page and you should see "Network Type". It is probably showing "unknown")
Touch "Run ping test" towards the top
Now your "Network Type" should be LTE

Good luck!!

Nope, my Network type usually says LTE, not unknown and pinging doesn't seem to help. I only have trouble staying in 4G if I'm using the hotspot to tether my laptop though. If I turn off the hotspot and use my phone instead of my laptop, it goes back to 4G and stays there. If I turn the hotspot back on, it drops to 3G unless I switch to LTE mode instead of CDMA + LTE/EvDo auto. Also, you can use LTEonOff or LTE Switch as a shortcut to bypass having to dial *#*#4636#*#*.

Thanks for the tip though. I hope it works for others. If your Network type says Unknown, pinging is worth a shot.
