Problem with phone connection - Galaxy S III General (US Carriers)

The bars slowly drop to nothing and then they go back up. Through all of this i have no service and no internet. I have already formatted my phone. It didn't work. I am on a Tmobile SGS 3. It shows 4G on my phone but nothing. Also i click up the micro SIM card and put it back in. I'll have temporary internet for a bit and then the problems start again. Thank u in advance.

did u check for enable data/internet/mobile network?
i did a sim card activation a while ago and internet stopped working so I started calling t-mobile, turned out data was turned off..lol
its not just data thats not working. The phone wont connect to tmobile. It would not find any network. Just shows me a x above the network signal bars. I have even tried a factory wipe. Nothing works. I fear it might be the s=off state thats causing it.

i think it was my sim reader/holder looks a lil coroded. so is now a 4in camera & media player

Note acts like sim card isn't installed and goes back and forth with having data.

Anyone else have this problem? It goes from full H+ to having the crossed out logo back and forth. Stock rooted rom.

What are your APN settings?
Make sure your SIM is all the way in as well

I'm on AT&T, using the "4G" phone APN. Works fine on the GS2.
The sim is a microsim in the adapter and fits great.

Out Of Service Problem

hello, im new to the xda community and android and i was hoping i could get help if possible so i bought this atrix off a friend for $60 just to start getting into android, so the problem is that when i insert a sim card and the bars are crossed out. i tried reflashing the baseband/radio to newer ones but the problem persists and keeps saying out of service under settings-> about phone-> status. also under network type says unknows, so i was hoping it has a fix which for the price i payed for i like it as a media player but im also looking to use the hspa+ speeds. yesterday i did get 1 bar and carrier name but for only 1-2 seconds.
edit: im trying to use it on at&t (forgot to mention the carrier)
this is what i get...
What network are you trying to use it on?
Sent from my MB860 using xda premium
im using at&t
go to settings-wireless-mobile-networks
access point names push the four squares button on the bottom left reset to default and choose hspa+
this is a flashable apn.ziphttp://db.tt/C0OdFBWr reset apns to default afterward and try to reinsert sim and power up
I'll try this tomorrow since im not near a computer right now and i'll post the results.

Ok so I tried the apn method but the problem still the same, im thinking its a hardware issue but like I said im not that much into android.

I have a very week signal at home, and I see the same screen like yours
so make sure you have a strong signal before you determine it's a h/w issue
thanks for all your guy's help, i ended up giving the phone to my brother so he can use as a media player. i really liked the phone so im probably going to get a working one
do you guys suggest another phone other than the atrix (looking for a 4g/hspa+ one)

No signal on T-Mobile

Im using T-Mobile and yesterday I got that empty service bars on the notification and it could only make emergency calls.

This happened on my first nexus 4. Nothing fixed it. Nothing. Hopefully your situation is different. If nothing works, flash back to stock and start the RMA process. Google said it was a hardware failure with mine by the way.

Did your happen when you first got it or after you had it for awhile? And what's the RMA process

The periodic loss of signal was there since day. I still have it on my new one. Others do as well, but one day it went out and never came back on. I believe it was a different issue than just random signal loss. Google said hardware failed in it. You have to contact Google to start an RMA. I'm also not implying that your signal won't come back on at some time either. Personally I would flash everything back to stock. Go to a t mobile store and get a new Sim card and if no signal still then contact Google

Under settings, then data, then mobile networks, then to network operators.
let it search, even if it doesn't find anything or errors.
Then click choose automatically.
If you frequently travel out of 3g/H areas, you need that checked or the phone won't roam from tower to tower. you will get no signal.
Also, if that don't work, you can try clicking on a network it finds, and let it register, your signal may come back.
This is a common problem with those that don't live in big cities or near full strength 3g/h areas.
The phone doesn't handle tower handoffs well. Crappy LG modems.

Most likely wouldn't but it would be one more "possible" problem eliminated.

I'm currently going through the RMA process over virtually the exact same issue. However, I've been running franco's nightlies lately and up until he restored the HSIC/wifi stuff to stock in r154 I was actually experiencing less data drops and rapid tower swapping (constantly going from 3g to H and back rendering consistent data inoperable). *shrug* I feel as if it's something in the hardware on the cusp of failing because sometimes it does it more and sometimes it does it less. It's rather weird. I'm also on T-mobile towers through an MVNO (Straight Talk).
I just cancelled and switched to ATT go phone.
I have RMA'd 2 devices, tried multpie new simcards, relflashed, tried new radios, and nothing worked.
It no longer switches from 3g to H on ATT network.
It stays in H constantly.
Also, no more signal drops or loss of signal.
I have 100% signal all the time now.
The data is a little more expensive, but worth it for the coverage so far.
It's not your phone, it's the tmobile network.

Wifi connectivity problems

Im having trouble staying connected to wifi at home, it stays connected as long as im in the living room close to the router but when i go into the bed room which is about 20ft away it disconnects and then reconnets several times. The router connection is 5ghz and only me and my wife use it.

First, make sure you've turned off "Auto Network Switch" in the advanced section of Wi-Fi settings (go to Wi-Fi settings and press the menu key and select advanced).
Second, turn off WiFi Power Save mode in the ServiceMenu. Go here for directions.
I done what you said i entered the codes you said to enter on my dial pad and it didnt bring up anything no services menus...nothing. but i did go to wifi and then advance and unchecked the box you said to uncheck and waited to see if it would kick me off and it did it still kicks me off wifi while im in my bed room.

If you're rooted, you'll need to go to /efs/carrier/HiddenMenu....
Open the HiddenMenu file in a text editor and change OFF to ON
Maintaining capitalization of the word ON
Save file.
Then reboot. Try those dialpad codes again.

Dial pad codes worked like a charm went in and changed the band to B4Enabled*. Now im gonna hang out in my room for awhile and see if i get kicked off my wifi. Thanks a bunch for you help i just hope this works oh and yes i went to text editor and then carrier and deleted OFF and replaced it with ON then restarted my device then went back into carrier to make sure it saved and all is good. Just hop it fixes my problem. Thanks again.
Now i need to tryn figure out how to make my call signal better....lots and lots of fun this phone is
When it kicked me off before it took awahile before it would connect back. While in the process of typing i got kicked off but connected back veryfast. Strange because im only about 15ft or so away from the router. I have noticed a big difference though, before my bars would fluxuwait from 1 bar to 5b now it usually stays at 5.
Anyother suggestions i can try
Go into your router settings and check/change the frequency(2.4-5) and the broadcast channel to match what the phone is using
Turns off the power save mode worked for me. Thanks. Now I don't want to flash to a custom to anymore. Thanks.

I just upgraded my wifi from 3megs up to 12 megs. Im still having trouble downloading files that are 1g and up. I downloaded speed test.net and checked my down & up down reads 10.92m and up reads 2.23m but when im downloading a file say its 1.25g it slows waaaay down to like .94m is it supposed to do do that? Im the only one connected to my wifi at the moment.

12mb/s is a pretty slow speed. It's going to take a long time to download it. When you're downloading a file the speed you see is Mb/s not mb/s. Megabytes and megabits are a lot different.
AT&T service person came out today and upgraded my internet, from 3megs to 12megs. I asked the tech how fast it would download a 2g movie his answer was, " it should take about 15 mins at the most". Wireless is just a f#@$in scam the co$k [email protected]$!ers will tell you anything so they can get ypur money! The highest they offer in my area is 12megs funny thing about 15 miles from where i live they offer 50megs. Its just a rip off!! Im feed up EVERYTHING IN THIS WORLD IS A MONEY RACKET...MONEY MONEY MONEY......IM SOOO PISSED
