Last week I stopped being able to use the internet, marketplace and streaming service on my Galaxy S 4g unless I'm on wi-fi. Today I realized it appears as if I'm no longer getting edge, 3g or 4g service. I have bars, but nothing next to it telling me what network I'm on.
My phone is rooted to stock with bloat removed and has been for months. Any ideas on how to fix this?
Try toggling airplane mode. Might help to remove your SIM card & ensure the contacts are clean then reseat it.

I'm having the same issue after moving CM7 => MIUI.
I've moved back to stock ROM XXJVT, but still not able to connect to 2G/3G. Anyone help.....
Btw, I'm sure the APN settings are correct and packet data is checked.

try taking the battery out for 10min
I guess I figured it out. But it doesn't seem very logical, but hey it works.
I changed the url of my provider from "live.vodafone.com" to "live .vodafone.com" (watch the space between live and .vodafone) and all of a sudden E/G/H appeared in the status bar.
Still, double check the APN settings, make sure everything is entered in right (proxy, username, authentication type, etc). Were you able to send pictures still? You need to make sure it's not a hardware problem.
When my phone shows the H symbol for network, it works well, but when I'm not using the network (no traffic), it falls back into 3g and gets stuck on upload. Occasionally, H service will come back, but often it won't. I have found if I turn the screen off, H service is restored.
I have had this problem for months now. I have a i9020a. Currently I have CM9 April 8th nightly installed, using the i9020AUCKJ1 radio. I just got done reverting to the stock build recently released from Google (IMM76D, I think), then upgrading to CM9.
No matter what I've done, nothing has worked:
1. reverting to stock then upgrading to a custom rom (Team-Kang, CyberGR, CM9, etc);
2. trying different radios;
3. opening phone info (*#*#4636#*#*) and changing it to GSM auto PRL as well as setting the band to USA;
4. making sure the APN is correct;
5. restoring the IMEI backup;
Any ideas what the issue could be?
H is 3G. Only active while data is being actively sent/received and it is actually feasible to use in your current area. Also, are you sure it is not only the animation that gets stuck?
Is there an actual problem, though? Is something not working quite right (data, sync, notifications, etc)?
It gets stuck on UMTS:3 (just keeps trying to upload) and won't work again until I turn off the screen and then it will usually revert to HSDPA:9.

you should download taskiller.. kill all app before you use your internet, i have same problem and always solved with that way..

While taskiller certainly kills most running processes, it does nothing to help my network connection.
On a separate note, my roommate has the same phone and his maintains a steady HSDPA:9 connection without ever dropping into a UMTS:3 connection.

The normal behavior of the phone is to use HSDPA while it's in need(download/upload) , when not in use automatically goes to UMTS:3
What ROM your room mate is using ? model ? radio ? network ?

You're talking totally rubbish ... Killing apps will not enhance anything and may even slow things down by needing more CPU power to open auto apps again...
I have expereinced the same issues with my 9020a on ATT. Sent phone to Samsung twice, changed SIM cards 4 times. Updated radios, now on 4.0.4 getting about 120 kbps download speeds while my other phone (work phone), iphone4s on att, gets about 5 mbps.
Call att, they credited me my entire months bill and offered a free galaxy note with a 2 year agreement. My thought is that ma' bell is just killing any unlocked phone or there are issues related to "LTE" rollout they wont admit to that is causing a disruption with 3.5G.
Anyways to the OP, you aren't alone. I too hope someon can help!
My roommate is using the same rom, CM9 (nightly from 3/29 though), radio is i9020xxkb3, network is also AT&T with same plan.
Watching the About Phone/Status on his phone, it stays on HSDPA:9.
My returns to UMTS:3 when not in use, but when in this mode, I get no network traffic at all. I will flash upload but will never download anything. Occasionally, H service will be restored, and I will get my network connection back.

Kind of cool. Mine showed the first option chosen but it hope between 3G and 4G as usual. Choosing LTE made no difference for me. I have virtually no 4g signal where I love

Airplane mode is a feature of the phone and turns off all radios. You can hold the power button and choose airplane mode or use the quick toggle in the notification window. Since it sounds like you may be in an area with weak 4G, you can also use an app called Phone Info to set it to CDMA auto (PRL) under Device Information. You can also change it back to LTE/CDMA/EvDO if you want it to switch as normal.
With the Verizon S3, is there the need to do *228 (or *22899) ? I did this every so often on my old HTC Incredible.

Doesn't work on LTE devices. A reboot essentially does the same thing. Some have recommended pulling the battery with the phone on, removing the sim card for about 30sec and then putting everything back in.
Thanks, I know what airplane mode is, wasn't sure where the APN setting was. I will look in to phone info though.

Are you guys also experiencing the "No Sim Card" and "No Network Connection" issues?
Or is this an entirely different issue?
When this phone goes to 3g, it does seem extra bad on how long it takes to switch back to 4g. i have areas where i live where it goes to 3g when going in between hill (less than a 50 foot stretch) and it will not go back to 4g for over 10 minutes if i dont manually do it. Not to mention my LTE never goes above 10 mbps on the best days
Somewhat related...If you use Anycut to create a shortcut to IOTHiddenMenu, enter the ##DATA# Menu, edit. Under "Advanced", there is an LTE toggle, under "Other" > "HDR/1X" you can set the phone mode, and then under "Other" > "LTE APN Settings" you can somewhat modify the APN settings, reset and discard. If it asks for a password, it's 000000.
I gave these a try. I'm trying to find a way for my phone to favor 4G when there's a 4G signal, no matter how weak.
Yesterday I did a test, 3G with 3 bars vs 4G with 0 to 1 and 4G had consistently faster download speeds and shorter ping times. The upload varied from similar to 3G to slower.

probably easier said than done. The phone info app can force LTE but you lose voice and text.
Ya I found that out yesterday when testing speeds. I went to send a text then make a call and no luck
Otherwise 4G service where I live could be excellent at one spot then a mile away no service. If I had excellent 4G consistently I'd consider GoSMS which I believe has the option for data text and also a separate VoIP app
Ah well hopefully something will be figured out eventually. With a strong 4G signal 4G is considerably faster and more consistent than my 20mbps home broadband

I've had similar issues with my network. I had no 4G in 4G areas, but mainly my wifi would disconnect randomly and 3G also dropped to 1X a lot. I ended up having to send it back and get another one. So far no issues. Also the new ones have an "Updated" sticker on them. I think it was just a software update they applied, but I never got the OTA on my old phone.

Your new phone came with an already updated firmware version I535VRALG1 instead of the original version I535VRALF2.

Did you get the "No Sim Card" notification and "No Network Connection" message?

Not sure if anyone will have the same luck I have with the "Phone Info" app, but with it I was able to get my 4g service back and my phone is functioning normally again. Just open the app, select Device Information and scroll down to "Set preferred network type" and select "LTE/CDMA/EvDo" then get out of the app.. 4g should return shortly there after. When I looked at it, my device was set to "GSM/CDMA auto (PRL)"
So here is what I am looking for... i have a Verizon SCH-i535, and what I am looking for is someone who has flashed the stock tmobile rom and changed the bands within the phone its self using the hidden menu (netmonitor app) to see if they can get more than just edge data... I have it flashed to AT&T right now and am using a friends T-mobile sim card that we cut down to fit into the SCH-i535 GS3... it seemed to sync with the towers and get mms.. text.. calls... and internet... just not 3g... I would like to know if someone has found a fix to this issue...
Thanks for your time.
Why not just flash the Verizon Jellybean Rom (Cleanrom or Jellywiz) since global mode was enabled in that Rom? Then drop your tmo sim in.

You know I had not thought about using the global mode on verizon.. I will have to give that a try... do you know if that will allow for 3g on tmobile?
Useful thread so far, but I have a several questions.
I currently have a Verizon Galaxy S3 SGH-i535 with a T-Mobile prepaid sim card (unlimited everything), I can call and text, but cannot get any network access.
I'm currently running Clean Rom 5, settings on Global. Is there any way I can enable data, preferred 3G? [due to that T-Mobile will get 4G on Verizon phones next month).
On CM10, I get Edge and can receive text, but cannot send text. Tried APN settings, etc. Is there a fix for this?
I have tried everything, but no luck. Any suggestions is appreciative

So what I did is i unlocked the bootloader... rooted it... and then flashed the AT&T stock rom on it and then plugged in the TMO sim card and then changed the bands to GSM auto. and it picked up edge... I was able to get access to the network with data... but the only catch was that it was slow as hell... as it was only edge. I am still working on programming to get the i535 on the tmobile bands... thus far I have not been able to get the phone on 4g or even 3g yet... I will keep you updated though.

have you tried using the hidden menu in the dial pad at all??
There is an app out there that will get access to the menu and allow you to change everything in the phone... but be very careful with this app as it can and will brick your phone if you do not know what you are doing with the app..
Netmonitor --> look for this on the google play store
To change the bands to at least get data on the phone, follow the instructions below:
1. install Netmonitor on the S3
2. open the app
3. hit the menu button
4. select field test
5.select UMTS
6. Select DEBUG SCREEN
7. Select PHONE CONTROL
8. Select NETWORK CONTROL
9. select BAND SELECTION
10. Select either AUTOMATIC or GSM Band Preference
* if you choose automatic the phone will look at the sim card and go from there to get the phone on the network to get data on the phone.
11. Select GSM ALL
This is the thread that I am following at the moment to get the phone on HSPA+ or 3G.. If you have anymore questions then please let me know I will do my best to help you out.

Hey,
Two SGS3 phones in the household. One's rooted with CleanROM and one's unrooted stock. Our phones doesn't go to 3G often. But when they do, they're pretty much useless. Browsing is extremely slow. The other day I tried to send a text with a picture, and it took over five minutes to send. Tried speedtest.net, and got sub dialup download speeds and almost no upload at all. I don't think that the 3G in this area is bad. I have friends with 3G phones that browse right along just fine.
Is there something that makes these phones operate so poorly in 3G? Is there anything that can be done?
Since you're rooted on one I imagine you can root the one having problems, I'd say root and flash a new modem that might solve your problems

One's rooted with CleanROM and VRBLK1 radio. The other one is unrooted and has whatever radio came with the last updated before this one that just came out. Each one is just as useless as the other.
Try different modems. Assuming that doesn't work, come back here and report which ones you tried with what result.
Also, I rarely get stuck under 3G, but when I do, going under More settings/mobile networks/network mode, change to GSM then back to Global. That pops me back onto 4G every time without fail.
Sent from my SCH-I535 using xda app-developers app
Are you in an area with 3g only, if so when I'm in such an area I use android tuner free or pro: then goto battery manager, on status tab bottom of page see tests, then device info, this brings up phone info page. scroll down and change to cdma auto prl. Then when back in 4g area change in regular settings to normal. Works great for me. If not it tries to find 4g constantly and with weak signal switches back and forth or stays on 3g with slow speeds.
Also like stated earlier try different modems and rpms, flash in pairs has worked best for me. And newest isn't always the best. I'm in Pensacola and newest is slower than mb1 or may is faster and better signal than md3.But each device is different. Good luck

Thanks. I'm on VRBLK1 right now, because I was told that it was the best one. But I doubt that my RPM matches. I read somewhere around here that RPM doesn't really matter. Wife's phone is on the update prior to this one that just came out, unrooted. So she's using whatever radio/rpm came with that.
I'm in a 4G area, and it's pretty rare that I end up on 3G. There are a couple of spotty areas close by that I always switch over. When I do, 1X is actually faster.
Can someone please point me to the location of the various radios that I can try. At least I can flash the RPM that goes with the one that I'm using. See if that makes a difference. I once had a bunch of them on my memory card, but that card died a while ago, and I lost everything.
Thanks!
There are a few things that you need to know before using the latest aio (all in one) radio files.
If you are running a 4.2 camera you shouldn't have any trouble, but the kernel you use can and will make a difference. If you flash the latest aio and camera doesn't work don't freak out, there are three options that I know of.
1 flash back to previous aio,
2 there is an aio with latest modem,rpm,and older tz (the tz is what messes up camera)
3 flash kernel that works with latest update
There is a thread on here about modems and it should be under android development thread probably just below pinned threads.

I was wondering if my method getting you back onto 4g by switching to GSM then back to global worked for you? Like I said it never failed me.
