Service issues. Annoying - AT&T Samsung Galaxy S II SGH-I777

I've been getting annoying service issues the past few days. I did in another state about 10 min away. And another county about 25min away. I keep leasing data. Or it will go in to emerancy calls only which makes me think its switching over to tmobile. Anyone know whats going on? Its not the area cause another att phone with me both times didn't have an issue at all! Im running surorom 7. With stock modem. Any one have an idea?
As I am typing this my phone done it. And it also likes to switch to edge a few times while in town.

opps. haha I just noticed. I dont know how I wound up here.

I have an I-777 and i keep having the same exact issue. It seems to happen alot when I'm more than 5 miles from home or work (where I spend 90% of my time.) I was on Omega with neak kernel and newest leak modem (***3 forgetting letters atm). Any help would be great I typically have great service and hspa+ all of the areas I travel.

Try replacing the sim card

Disable LTE on AT&T?

Is there any way to disable LTE yet on the S3 from AT&T? Widget, APN Add, etc??
Thanks!
I need that too for a better battery life.
Have you tried going to dialer and entering*#2263#. On Canadian model you can do this.

AT&T removed it for reasons I listed in a past post if I am not mistaken. I can rewrite the post later, just in a rush to head off to work
Puts me into service mode, but no options in there - Just says "RAT Selection option is restricted."
My Sprint S3 ran for 20+ hours on 3G without any issues, but since their data is so aweful we went to AT&T and on 4G lte we get 8 hours if we are lucky.
I guess the only other option is to flash a Canadian modem .

very weak signal

I purchased a galaxy s3 international version about a month ago. The phone was working fine for about a month until yesterday, my phone is getting very little or no signal at all. also, when i connect my phone to my car, the phone will start calling itself. i performed a factory reset and the bluetooth problem was gone, but the phone is still getting very little to no signal. wifi is working fine. i called Rogers, my service provider. all they ask me to do was to buy a new sim card or remove the battery from the phone and wait. none of those helped... :crying: i'm kind of desperate here as i can't figure out what went wrong with it... my phone is not rooted or anything... if someone can help me out, i would really really appreciate it. :crying::crying:
Unless you are willing to start flashing modems to your phone there isn't much we can do for you.
Best bet is to keep pestering your carrier if you don't wanna root and modify your phone.

thx for the quick reply. So rooting my phone and flash a new rom is the only solution? :crying: is it possible it's hardware problem?
Not a Rom, not before trying modems anyway.
It may be hardware related, you should keep pestering your carrier for a replacement.
If it world fine before then chances are its a hardware issue or the cell tower near you is down.

i just found out in my mobile network setting under access point names, there's LTE ththering and Rogers LTE, could this be the problem? cus my phone doesn't have LTE maybe that's why? sorry, i'm not very good at phone stuff, it's just my random guess...
Is your phone International I9300 ????
Or are you possibly and no offense meant in the wrong forum ??##

Did you try with a SIM of other network? This may at least point out that either it is network problem or hardware problem.

I don't have another micro SIM... I tried flashing different modem and firmware. But none of them works... the phone is connected to the network, just the signal is extremely low all of a sudden... I had an software update 3 days ago, maybe that's why?

Losing signal

I have the AT&T One and I am running the stock GE rom. I am in a heavily wooded area in northern united states and I'm able to get a cellular connection right after turning the phone on, but then after 60 seconds I lose the signal. I'm able to send and receive texts for that 60 seconds. If I restart the phone I get that signal back for 60 seconds and then it dies. I have tried flashing two different radios. Same result.

I'm not an owner of a HTC one but just cruising around on your forums but I know with the note 2 and the inspire i use to have, you would always have to make sure the ril file matches the modem file to work correctly. I know AOSP with other phones don't come with a ril file, so unless google edition rom stock modem works with your phone your always going to have poor reception.

Google edition roms aren't based on AOSP so they shouldn't have any issues but either way don't humor this guy.

Did the stock ROM work? If not then call AT&T and ask if there's anything you can do.
Its actually coming and going now. If someone could link me an AT&T modem I can flash that would be great

Well I have this ISSUE at one location but ONLY on LTE phones cause its near LTE coverage area and it prefers it over anything else Just force the phone to WCDMA only and BAM Fixed! The HTC One has been a little worse than my other phones about it but the problem has occurred on my Note 1, Note 2, S4, One X+, One.

Getting the i777 to work on t-mo

I am a bit confussed. Trying to get a straight talk s2 to work on t-mo for my brother. Rooted and running the collective rom on the phone. popping his t-mo card in the phone does not bring up a sim locked message, and I get no carrier signal. What do I need to do to get voice signal. does data work on this with a t-mo card? Do I tell him to move on?
Thanks

Signal strength problems

I had always read that Samsung phones had signal issues on cdma networks. This is my first Samsung device after several HTC. My wife and I are both dropping calls daily in front of our house. I cannot hold a call in my front entry way. Our previous rezound and thunderbolts did not have this problem and neither do our kids droid DNAs.
I called Verizon about getting a network extender because other than signal issues, we love the notes. They want 300 for it. I refused. They sent out techs to check signal in our location and say we have 3 towers blanketing our area so it's the phone. Still won't give us a free network extender. They agree it's a device problem. They say they have no phone comparable to the note to switch to and said there was nothing they could do. I told them to send another note to try. I guess I will keep going through notes until they other me the new Motorola's in a couple of months. They did offer me an upgrade, but I'm not giving up unlimited data.
I might hold out and try to get the next HTC phone that drops, either DNA 2 or one.
It really sucks because otherwise this phone is the best but dropping calls daily really sucks...

Just hang in there, after you get a few replacements from VZ they will offer you a different model.
I think I'm going to hold out. It might take awhile. I'll only take a phone with 32gb of storage and a big battery unless it comes with sd card slot

Thanks for the link, but I shouldn't have to buy extra equipment because Samsung can't make good cdma radios.
Curious if anyone else has wifi drops regularly. Both my phone and tablet drop and reconnect wifi pretty often. You see a message that briefly pops up.

My note does not have any issues with wifi. Check that its the phone and not the router.... really really sounds like its not the phone.
As for signal issues, My note did have issues with verizon. i switched to AT&T with the same phone and its 10x better. Probably more to do with my area than actual reception problems though.
Interesting my note gets far better signal strength than my 2 previous HTC devices I had. The only thing I don't think it matches up to is Motorola who I believe build the best radios period.

Don't think it's the router because it happens on both my note 2 and note 10.1
at home and at work. Sometimes it will kill downloads, sometimes it's fast enough not to matter.

The signal strengths match in setting between Samsung and HTC, but HTC phones seem to hold lower signal better where Samsung just gives up and you lose the call. Also, Samsung is quicker to jump over to 3g while HTC holds onto that one bar of lte better.
This has been reproducible for me on multiple Samsung and HTC devices (2 notes, 2 thunderbolts, rezound, 2 DNAs)

Just to follow up, took kids to dentist yesterday which is in a small town, outside of San Antonio. My phone had 1x, kids dnas had a couple of bars of 3g.
Swapped mine for a new note 2 (refurb) and is still dropping calls. Think I might just have to buy the extender...
