Problem with network set to auto gsm/wcdma

I'm having problems when my network is set to auto gsm/wcdma. The phone will get stuck when it switches and I lose service. This has been going on ever since I rooted my phone. I've tried several different ROMS, with their suggested radio flashed and the only way I keep service is if I manually set it to gsm mode only. The problem with that is the internet incredibly slow, which is annoying. Is anyone else having this problem? I'd like to be able to just use the phone without having to worry about losing service.

haven't had any issues with losing service or constantly switching between 2 and 3g.
have you tried managing your apn settings?

select "prefer wcdma" in apn settings

Preferred network mode is what you're talking about right? I'll put it on WCDMA only and see if that does anything. I'm pretty sure I've tried this before though.

Only thing I touch in there is what I've said above.

Tried using wcdma only. Then my friend called my gfs phone and asked for me. So back to slow internet and gsm only. I'm about to smash this phone and get it replaced by best buy protection plan. It would be nice for the phone to work without having to do a bunch of extra things.

He said he called me twice, the phone was in my hand the whole time and never rang.

Why does he have your gf's number in the first place?

I had a similar issue here in San Francisco... I believe it's because we're in an area with a 850mhz and 1900mhz overlay. I kept bouncing back and forth between the two. Some areas such as South San Francisco and crossing into the East Bay I'd bounce between "H" and "3G" ... and voice was a mess.
The way I got around it was to completely restore to off-the-shelf condition, and then re-root, re-flash the stock ATT rooted rom, and my problems vanished.
Even when I had my iPhone I had to reprogram my phone to prefer 850mhz here in the city, and manually switch to 1900 when I'd leave the city. AT&T's implementation of the intertwined 850\1900 in san Francisco is still fairly young, and it's pretty bad.

So to do that I would just flash the stock ATT Rom, then re do the whole root process and then flash the rooted version of the stock rom?

Oh, I've already tried to do that. I just leave it in GSM only mode and it has no problems, except slow internet...

I just tried flashing the ROOTED stock rom, no go. Changed APN settings, nothing. Now after trying to restore backup of revolution 4g rom, clockwork locks up and I have to boot back into this stockish rom. And the internet works. WTF I'm about to just smash this phone with a sledge hammer, get it replaced by best buy's protection plan, and leave the new one stock.

I've noticed this multiple times, on different ROMs/radios. But tbh, I've noticed it on my last 3 devices with ATT as well. There are times, usually when bouncing back and forth between networks, where I just can NOT call out, and when I call my phone it rings on the calling end, but my phone never rings. I've chalked this up to ATT sucking... I've learned to live with it, if you need me that bad leave a voicemail and I'll call you back.
Also - There are multiple times that I've called my fiance (who has an iPhone 3GS) and it's rings on my end, but never rings on her end. This tells me that this problem is DEFINITELY not device specific

[Q] HSUPA and Data on Captivate Help

I seem to be having an issue with my data and am trying to narrow down the reasons for my problem. The issue is I CANNOT use HSUPA (H) for data, I always get a connection timed out issue. I put the phone in 2G GSM mode only and have data working, but of course I was spoiled with better speed I can't stand it.
My question is if AT&T could be doing upgrades to the towers in my area, will that affect my speeds, or is something broken internally in my phone. When I select WCDMA mode, it takes FOREVER for it to connect and says searching for a long time but does connect or displays (H) with 3/4 bars of signal. My friend has an unrooted captivate on 3G and has no issue with data. Does anyone know the cause of this.
I have tried a few different modems (jl3, jk4, kp1....) all the same and have tried 2 different OS's with same data timed out issues while trying to use (H). I am currently in the process of flashing back to stock to see if that will resolve the issue. Thank you for your time guys.

H doesn't necessary mean HSUPA. It simply means HSPA (HSDPA only or HSDPA and HSUPA). You didn't mention anything about your firmware but I guess you are experiment with non-Captivate firmware and modem combination trying to get HDUPA working. From what you described, it seems your current firmware and modem combinations lacks 850MHz support for 3G (most European firmwares lacks 850Mhz) and your local tower happens to use 850MHz, not 1900Mhz. Just a guess.

Make sure you have the modern set to proper frequency (WCDMA 850 or 1900) for your area. The modem thread can tell you all about how to do it.

Sorry guys, I guess that was an important part I forgot. I was running Andromeda and thought the same so tried Cognition 4.1.1. Also after going to stock 2.1 I still have the data issue. I can connect to wifi just fine, but no using ATT data will work.
I called customer service and walked through the steps as usual and after some looking into my area, he said there were 3 towers reporting severely degraded. It just sucks seeing my friends phones working with no issues. He said that repairs are stated to be finished sometime in the next few days and to call back later in the week if the problem persists.

Looks like you tried both i897ROM and non-i897 ROM, so it's not firmware related.
Did you try to put someone else's SIM into ur captivate? How about some other devices in ur area?

I didn't think about trying my friends sim card. I will test tomorrow morning. Ty for the idea to isolate the problem to my phone!

umm not really related to your phone. but im suggesting its the tower upgrades getting them ready for 4G that is causing your phone to act up. i have a HD2 and we have 3G down here. but since early march i get nothing but EDGE. what happens in the month march? AT&T will be launching 4G in selected markets. it was confirmed once i was talking to a AT&T tech. so im just waiting to see what happens in the end of this month.
NOTE: it could also be your sim card having problems. AT&T replaced mine thinking it was a problem with the sim card since i have a AT&T native W350 and i was getting the same problems. call them up again and ask to talk to a tech and tell them your having a problem with your sim card. they will set you up a appointment at a corporate store. free of charge.

Is it?

you would have data, but no voice

Sorry for nor replying sooner. My 3G data seems to be working again. My lack of in depth knowledge is why I put the hsupa above when my phone displayed H I didn't know what to call it.
It must have been tower upgrades. I didn't restart my phone and left it on the charger overnight and the next morning I had no issues. I did a reboot of the phone as a test and connected with data with no issue. Too bad as I was close to getting a replacement, though it would suck and be my luck to get one with other issues. Mine is a 1007 and works perfect (other than the obvious GPS.)

[Q] How to enable EDGE connectivity...

All right I've went through all the posts regarding this and none of the options seem to work. I have terrible 3G/4G signal where I live. How can I set the network!!??!! Tried the apps tried the *#*# stuff (all I get with that is "RAT selection restricted!" WTF is RAT?) I can't even make a phone call or send a simple text with the one bar of 3G/4G I get. I know most are probably against the merger but I will hopefully benefit from it cuz there is a T-Mo tower down the street from me. Anyhow please help. I'm rooted, stock AT&T, 2.2.1

It's only possible with Rogers-based ROMs (e.g. Infused v2.x)
It's not possible with the stock AT&T ROM or any derivatives, and causes all sorts of problems with CM7.
Hopefully AT&T's Gingerbread update will fix this.

Infused v2 is Rogers-based.

Entropy, I was able to force 2G with Infused 1.5.3 when I had it paired with the Rogers modem. I used the star code *#2263# and that allowed me to select a GSM only band.
Also, on current infused.v2 builds, I cannot force 2G as they're not using Rogers modem and I don't feel like flashing another modem and bricking it on these test builds.

Q: I don't have data anymore

So I recently bought the girlfriend a Samsung Galaxy S 4g. Definitely a bit different than the Evo in terms of the overall process. It didn't help that I started out in the Vibrant forums somehow...
Anyway. As it stands right now I have her phone all rooted and it has CWM and I'm using the Valhalla ROM. The issue is that she doesn't have data.... and when I go into wireless networks and check out the mobile networks and such, I can never actually see T-Mobile. If I search I can see AT&T, which I connect to and I start roaming. If I do this I still don't actually have internet. I can't use the market, or the web browser or facebook or anything that requires data. The browser will sometimes redirect me to some web2go website, otherwise it just times out or says it can't connect to the server.
So does anybody know what's going on? Please let me know if you need any more details.
I've never had trouble like this between my Evo, or my Epic 4g Touch or any friends phones. I've also tried going back to 100% stock unrooted GB and I still have the exact same problem. The ROM doesn't seem to matter, neither does being rooted.

Since you are running Valhalla bring down the notification bar and make sure you have the data toggle on.

Yep, it's definitely toggled to on. I even cycle airplane mode and make sure it's on afterwards.

Only other thing I would suggest is a factory reset. The phone should be picking up the T-mobile network without any problems. But if rooted or not and on stock vs custom rom the issue remains you may just have to set it back to stock and send it in for replacement.
And I know this is a silly question but make sure you call T-mobile and verify that this line has data plan. It has happened in the past when I added a line that it wasn't provisioned correctly and out of the blue the data stopped working. The service was automatically removed due to a reps mistake.

Check your APN settings. Should be T-Mobile's, if not then that's what causing the issue. Just look up for those on google.
Sent from my SGS4G using xda forum app

My APN settings are correct. I've now tried several other APN settings though, and this hasn't helped.
I know this phone is on a data plan. It's on the $50.00 a month prepaid. It did work when we got it, and after it was rooted. I just noticed recently that it stopped working, and I'm not sure at what point it happened, and if it has anything to do with what I've done.
I called tmobile and they said they couldn't see any network related issues going on. Just my phone not connecting, so it was made a ticket for the engineers I guess haha. They are supposed to work on it, and they usually will either fix it and never contact you, or call you if they need you to do something.

Bump.
I've been in really good service areas with full bars T-Mobile and I still don't have internet. So I really don't know what's up. The "T-Mobile engineers" haven't called me back or fixed anything yet.
I'm about to bring myself back to stock and bring it in to a store.

Bring it back to stock & maybe put it in recovery mode & wipe caches & do factory reset again. See if that helps before returning it.

You might try reflashing the ROM or maybe just flash a different modem. I had issues like that once when i was on black ice. If you had data before, there probably isn't anything wrong with your phone.

Having the same Data problem
I had an unlocked ATT BB Curve on T-Mobile and the data was working (although very slow...)
I decided to try out a "Vibrant" hoping to be able to install ICS via Cyanablahblah.
Searching on Ebay I bought one only it turned out to be the 4G (it didn't realize there was a difference.)
Since then I can't get DATA on the 4G except in WiFi.
On the network it goes to the page: u.web2go.com and says my data plan does not work on this device.
Has anybody had any success with this problem ?
Could it be a 4G issue ? Before DATA came from Edge.

Have you checked what your APN settings should be with the magics of Google?

Is there any way to fool it with a 3G modem flash or something ?
I think I screwed up when I bought the phone not realizing there were 2 variants of the "Vibrant."
I wonder if I would have this problem with the earlier (non "V") 3g phone.

Probably. If it were just the 3G/4G causing the problem, you can force the SGS4G to only use 2G networks in the data settings... but if it's anything like the old Verizon bits with tethering and other data, they check for specific data strings that are harder to fake... I mean, set.

[Q] sch-i535 on t-mobile

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.

In the mean time, I will see if the CM or AOKP team can implement these settings.

that would be great! If I can help in any other way let me know.. or if they have questions please give them a link to this thread. and I will be more than happy to talk to them.

hey guys sorry that it has taken awhile for me to get back to you.. so I flashed the TMO rom on the I5 and got the same results just edge. I think that I am going to try using bobloblaw1 suggestion and flash the verizon leaked jellybean rom and then use global mode to be able to see if I am going to be able to get more than edge...
Here is a guide if you do not know how to flash roms on your S3 here

greetings, all.
i have the same problem that you are describing. running CM 11 Nightly (but problem also existed on VZW stock & CM 10.2). i have read all the forum's about this topic, but as of yet there seems to be no SURE fix to get anything faster than Edge data from T-mobile.
