Signal Problems - AT&T Samsung Galaxy S II SGH-I777

Hi guys I recently got my at&t galaxy s2 unlocked and switched to T-Mobile but I still have the at&t version of the galaxy s2. The thing is, whenever I'm using data, the signal keeps dropping even when I am in a still position. For example, when I first start data, it will be at H+ (this is normal hspa+ network) within 5 minutes, it drops to 3g and then down to edge. And then sometimes the signal completely goes out so that data doesn't work. This basically happens every time I turn on data. Any ideas why this could be happening and how I can fix this?
Thanks

Problems with Edge to H+

I just noticed the past couple of days that when I go into the city my phone doesn't switch from Edge to "H+" it just sticks to Edge. I have run a speed test multiple times to confirm it was still on 2g data. I have to turn my phone off and on in order for 3g speeds to occur. I have replaced my sim card and no better results.
Any ideas??

i'll be interested in a fix also but a faster way to get 3g would be to put your phone in airplane mode and back again instead of restarting.

Losing signal on Bell network

So I had the pnone fora few days now and I lose connection to data and voice at least 5 times a dat. The apn settings are all correct. Any reason for this?
anyone have any idea? Its driving me insane
Have noticed covering the bottom of the phone with my hand cuts the single in poor reception areas ... like west Wales coast. currently holding top of phone in landscape to get enough of a service to type this. but service is very poor here.

same problem with telus.... i bought a bell sg2 and unlocked it and have looses connection and data like 5 times a day

[Q] galaxy s3 signal dropping?

hi all,
anyone having issues with signal dropping and calls droppimg on the galaxy s3?
Im with o2 uk and the missus is with 3uk and we both have the same issue with signal loss and calls dropping. even if we both have full signal calls drop an theres loss of signal for a few seconds then it comes back.
is this a known issue? surely both of our handsets are not faulty with the exact issue?
cheers,
ed
Yeah I have signal issues, I'm on giffgaff. I've tried flashing a few modems but reception and call drops are still here

Mobile data "Disconnected"

This is new. My phone shows full signal bars, but data does not work (no LTE displayed in the status bar). When I look at the settings it says "Disconnected" right below Mobile data. If I turn it off and on, it will say "Turning On..." then "Disconnected".
The weird part is that I know I get LTE signal right here (at my desk at work). I've been using the phone here all week. It was working fine, then it switched to disconnected. The first time I turned the data off/on, it connected, showed LTE, and sent an email I had tried to send. Now it refuses to connect at all.
I rebooted the phone, and it first connected to LTE, and now has full bars of 3G.
Anyone else notice something similar happen?
EDIT: Looks like it's Verizon possibly doing some tower work in NYC.
its possible you have a toasted sim card. not very common but i have seen it happen before on my gnex and a few others. Good luck
Another possibility is that Verizon in your area is fixing things.
If you are in Manhattan, a couple of us experienced unstable data connection these few days.
If such data disconnection happens cross the country , then it is a device's issue, which I suspect not.

Same thing keeps happening to me. It's frustrating because it will spool up LTE with full bars, not transmit any data and then disconnect completely from data. Will have to restart my phone which normally gets me back to working 3G until it happens again in an hour or so and have to repeat the process. Toggling the data connection on and off doesn't help. Verizon replaced my SIM card but it hasn't helped anything. Hoping it's just a temporary NYC issue.

I was having a few issues here in New York too. I think they're working on some towers.

Not surprising given some of the photos I've seen of their infrastructure after Sandy. Good to hear I'm not the only one.
This could be a different problem, but today I completely lost all mobile signal, both data and voice. It looked like I was in the subway (with no data icon and a little x next to the bars) . I waited for a couple of hours to see if the signal comes back, but it did not. A reboot fixed the issue.
I would not think much of this typically, but my wife has complained about exactly the same thing. Said she had to reboot the phone on two occasions already to get the signal back. WiFi worked fine though.
Could be a bug with the DNA.

are you in NYC metro? If yes, yes, I had one of such issue today too. but it did not last hours. It lasted 1 minute or so.
I think folks having data problem near NYC may chill for now. I hope it will not persist throughout the trial window of 14 days...
I am in NYC, let's hope it's a VZW issue.

Data seems to be working today. Looks to be a Verizon issue, not a DNA issue.

I have the SAME ISSUE, doesn't happen often, but when it does a reboot fixes it. I'm in Oklahoma. No problems last couple days, it's weird.

I had that issue than I took my sim out looked at it noticed a big ol finger print on it and took an eraser from a pencil lightly wiped it away and have not had the sim issue since

My wife was having issues with mobile signal until eventually the phone could not find the sim card. She took it out and put it back in. Problem solved.
I am quite impressed with her. Coming from an iPhone, which she called as stable and boring as a microwave, she is now rocking a themed launcher, all sorts of widgets, power Toggles, settings profiles, and messing with the sim card!

I had that issue with the Galaxy S2.
Simple and fast solution: walk into a local carrier store and pop in a new one. It's free, and surely saves time without having to stress over troubleshooting it
Hi Everyone,
I got the same issue. I did a quick search on xda for this issue and saw this thread on this topic.
I opted to get the HTC One X+ instead of the DNA.
The first week I got the phone (from UK) everything worked fine and now I can't get the data connection to work.
I am currently on Vodafone.
The funny thing is, I take the same SIM card put it into my HTC One X which I got here in Australia and it works fine. No problems, always get a data connection.
However since the new HTC One X+ worked fine for the last few weeks and now it doesn't, I don't think it has anything to do with the networks.
Now since DNA is having this same issue, I am wondering if it has to do with Jelly Bean or the Sense upgrade using the HTC One +(plus).
Very frustrating. Any further thoughts about this bloody frustrating issue ?

As stated, the same SIM card when put into my HTC One X works fine. I get a data connection right away?
Update. Got it working again. Network connections are a bit sensitive.
Will monitor this issue over the next week.
So it is not necessarily the SIM Card.

UPDATE !
I still have this frustrating problem. With my galaxy note 10.1 I have 75% connection on GSM and a network connection. With HTC One X+ 20% connection on GSM and NO network connection.
Is anyone else experiencing this?
Any suggestions anyone?
I have the same issue and I live in California. I think it's definitely a Droid DNA issue, not the Verizon network. I lose all mobile data, not just LTE. It happens probably a few times a day and even when I'm in the middle of a phone call. I'll have to restart my phone to get it working, but I've even had a couple of times where even a restart didn't work and I had to shut the phone off completely multiple times. This issue is rather frustrating!

Same issue here, I've continue to search the internet for a solution. I don't even know if it is hardware or software issue. It always disconnects exactly when I need it, so frustrating!!!!!!

It might not be a VZW problem but just incase go to a Vzw store and ask them if there are any down towers on the area if there aren't ask them for a warranty cpo replacement DNA. Hope this helps.

[Q] Note keeps roaming?? AT&T note, using on T-mobile Padawan6/T989UVLC8

Weird problem with my note. It will randomly start roaming and lose data connection. This is extremely often, like every few minutes when I'm using data. I have Padawan 6 and the T989UVLC8 radio. Data roaming is turned off. Am I doing something wrong or need to find a different combination, anyone else having a roaming problem on T-Mobile? Thanks.
Well fixed my own problem. Flashed the SGH-I717-UCLF6BS ROM along with the Official TMo ICS RADIO_NOTE baseband and it's all running like butter. Solid 4G, doesn't roam and data picks up quick from idle. Will report if anything weird happens.
