Why isn't my 3G working? - Android Q&A, Help & Troubleshooting

A couple of days ago, I realized that my 3G wasn't working. What's odd is that the 3G symbol is still there next to my bars, and I can see the up and down arrows turning off and on like it's working. I've tried updating my radio, and even reputed a tried flashing my ROM again, to no avail. Any suggestions?

Signal issues DX2

I have a dx2 with cm7 and have been having signal issues, only with 3g no cell issues. The signal strength stays above -80 dbm most of the time, while my dads hunderbolt hangs around -63dbm and we have a cell tower in sight of us, has anyone here found a way to remedy this other then getting a new phone?

Has it been a recent issue? Ive noticed on my DX2CM7 the past couple days that my 3G has been cutting out and the speed is VERY slow. On average today im getting about 32kB/s down and 120kB/s up.
Im lucky to get that good of speed, its been on and off not to bad. Ive been noticing its been alot worse lately.

I applied some mods I found and the 3g works allot better even though I still get a bad signal.

Gotta ask an off topic question...where in the north do you roam? And I am unsure as well.. I have always ran those mods and never seen any ill affects with any rom...although I have not run rc1

Usually in Minnesota at the moment, but roamed North Dakota and Montana for 4/6 months I hit Michigan a couple times a year, little bit of Wisconsin too.
I never had any issues with the mods on rc0 but rc1 came out and i had to flash it, now im thinking bout heading back to eclipse and the lovely poison green for awhile

There's an app on google play called 3g/4g speed optimizer, I have it set on little fast and it has given a bit more speed. It does consume more battery and get a little hotter though but thats only when downloading or browsing the web.

I compared my wife's dx2 signal (stock) to mine (RC1) and they were exactly the same.

Well that atleast proves the CM isnt responsible for poor signal.

Wow just read this thread. I can honestly say since rc1 I have had my 3g trip out(not working). But I rebooted and it went away.

Losing data connection

Hello all. I keep having issues with keeping mobile data working. Ill be surfing one minute then cut from data the next then i have to put it in airplane mode and take it back out for it to start working again. This happens quite a few times a day. I have tried making the new apn for internet as stated in one of the threads and it still did it. I switched to a wap.Cingular apn same thing happens. Im at wits end. This has happened on stock and several roms. I'm not in an lte area either. Can anyone help? Thanks.

What Radio are you running? I had similar issues on the UCLC5 radio, and they went away when I went back to the UCLC1 radio. The UCLC5 is paired with most ICS ROMs.
It could have been a bad flash of the Radio, because I'm now back on ICS with UCLC5 radio and I'm not experiencing any issues.
Good Luck!
I actually posted a thread about this a couple of weeks ago because the same thing was happening to me. Att just sent me a new sim card and that fixed the issue. But as of today it started happening again. I was on Seraphim rom coupled with the tablet mod and my data wasn't working. It would only work after turning on and off Airplane mode. Since then I flashed back to the unofficial Emily rom and haven't had an issue as of this morning.

I was Emily Saturday and didn't notice any issues that i can recall but i love alpha 2 with the tablet mode where do i get that radio and will it work with alpha 2? Thanks

Phone does not connect to 4g

Since I'm on my phone I'll make it quick does any one else lose complete signal of 4g? I'm not connected at all even though I'm on a signal 4g area oh and I've been s off for over a month and problems just started last week and it seems my phone never connects to 4g l

Try RUU'ing and then doing a factory reset in bootloader. That worked for me.
Sent from my ADR6425LVW using Tapatalk 2
There's been a lot of problems with people staying connected to 4g in the past two months. There are already a few threads on it. I called up Verizon and they said they are working on a solution. Some people said they got a new red sim card that worked. I have heard its new so I haven't check to see if my sim switch was to the red one or not. I would reset the phone and try the sim switch if it isn't working call Verizon to add to those who have an issue. IRA not just rezounds its all 4g phones accross the country. Right now I am on 3g most the time in a 4g area (it was already 4g when I got the phone in novemeber no probs till June). Anyhow hope I helped.

changing my preferred network choice in the radio settings from "CDMA+LTE/EvDo" auto to "LTE,CDMA" makes a big difference when I'm having that problem in my area.
I woke up this morning to 4g. Mojave desert so cal. Never thought it would get here.

Liquid ICS 1.5 WIFI issue

My wifi will not stay connected. I have searched the forums and have not found an answer yet. Any help is appreciated. Please let me know what info is needed to help trouble shoot.

WiFi has been solid for me on his build. What recovery are you using?

I used ROM manager to install. Did all the wipes just like previous installs I have done.
Sent from my ThunderBolt using xda app-developers app
Download 4ext recovery and use the wipe all except sd card before flashing. Cwm is extremely outdated and people are having issues like that after using it.
Sent from my ADR6400L using Tapatalk 2
I will give that a try. Is that the recovery tool of choice these days?
Thanks for the help btw

Check your radio version. If you're not using the .19 radios give them a shot.

Well, I put these radios on:
1.49.00.0406w_1, 0.02.00.0312r
I have the same issue. lol
This is getting pretty sad. Do you have any other suggestions?
Maybe try to download the Rom again. Then reflash in 4ext.

At least I have unlimited data, lol. Still would be nice to have WiFi working because we only have a weak 3G signal at our home.
Did it work before you started using that Rom? My other suggestion would be to try a different ics Rom. Sorry I wasn't able to help but you're not the only with that problem. I'm surprised that no one else hasn't tried to help.
Sent from my ADR6400L using Tapatalk 2
It worked fine before ics. I will look into trying a different build but I really like this one.

Yea it is a great build it sucks you're having WiFi problems. Have you tried changing channels on the phone side?
Sent from my ADR6400L using Tapatalk 2
I had the same issue, I used the tweaked combo radio that used the .19 CDMA radio, with the leaked ICS LTE radio.
Well, I don't know how or why but it works now. I got mad and took the battery out and left it for a day. When I put it back in and turned it on it was working.

Question concerning this ROM as well. My signal bars either constantly indicate 2 bars for the 4 bar version, or full for the 6 bar signal version, and nothing else unless I am not on 4G. I saw someone posted this question somewhere else about a week ago or longer but I have been unable to locate it since I have been using the ROM. My data connection is usually fine so I wasn't sure if it'd be the radio I'm using or something with the ROM and if I may need to reflash.

I'm having that now with every rom I flash. GB and ICS based. It seems worse with ICS leaks, but it's a problem for me across the board.

Network connectivity issues

Hey guys, i have no idea what has happened, but i no longer have 4g on my phone.
First, it takes forever to actually connect to Mobile data. It shows that mobile data is on, but it says "disconnected" for at least a minute or two. Second it only connects to 3g when i know im in a 4g area, and have always gotten 4g.
I have it set to LTE/CDMA mode and have sprint connnections optimizer turned off. I have also updated prl/profile to no avail. Please help
Thanks
It's been around the posts lately about the growing problem. Try ##3282#, profile, change to 1, hit menu, commit modifications... Maybe that will help.

Thanks, it was already set on 1.

Well... I'm in the same boat man. But I'm actually going on a couple hours of constant lte. Man, I did everything in the book. ##786# reset, hundreds of profile and prl updates...
I flashed back to an old nandroid of superlte and its been working.

I'm basically having the same issue. The other thing on my end is I can't update prl or profile. This sucks.
Sent from under your bed...
This happened to me the other day. What i did was turn off my mobile data and put my phone on airplane mode for a few minutes. Then i turned everything back on and my LTE worked.
Woke up this morning and my 4g was back! Guess its a tower or software issue. It seems to be randomly disappearing for no reason. Hope you guys get it solved cuz if not then the phone should've been called EVO 3G if its gonna act like this. I'm sure I haven't seen the last of this problem
Sent from my EVO using xda app-developers app
Been having similar issues for the last day or so as well. It sometimes requires me to restart the phone entirely before I get LTE back. Where are you guys around? Chicagoland area here.
