3g 2g toggle issues

I can't remember if it was CM6.1 rc1, rc2, or rc3 but some where along the line the 2g 2g/3g toggling has gotten weird. If I switch the data symbol on the top (G,E,3G, or H) goes away and I never get data back. If I mess around and toggle it a few times it eventually comes back, if I reboot the data comes back until I try to toggle again. Does anybody have any suggestions?
I googled this problem and found one person that had a similar issue and some one else responded saying they got a new sim card and that fixed the problem. I just can't see how the sim would have anything to do with this and more importantly I don't want it to be the sim. I was hoping for a "not leave the house or open my wallet" sort of solution

T-mo practically gives away sim cards. No joke, I used to get new ones all the time, my old phone fried them like no other.
Anyway, it's actually quite possible that it is the sim card. People have solved low signal issues with a SIM replacement, likewise, issues with connectivity after switching frequencies could have something to do with a damaged or worn sim card. If you found someone with a similar problem that solved it with a SIM replacement then that would be my first step if I were you. After that I would redownload and reflash your ROM, to eliminate corruption.

thanks for the response, maybe I will get a new sim, I just wonder what I should say as far as why I think I need a new one.

Disregard the random thanks, I'm still not used to the quote button not being on the outside haha.
I don't know, the store I go to, if I just walk in and ask for a new sim card they just ask for my account info and give me one. If they ask for a reason just say you're having connectivity issues or that your phone isn't recognizing your SIM anymore. They won't pursue it, it's an incredibly inexpensive card.
Also, why isn't there an "unthanks" button. Kinda sucks xD

I got a new sim, wiped, and reflashed and still the same problem. However I noticed that if I wait long enough it does eventually toggle, so I guess the problem is a ridiculously slow 2g -2g/3g toggle

Well it does take up to 30 seconds to switch the radio mode yes but I thought it wasn't reconnecting after you toggled at all.

I didn't think it was, it used to only take 30 seconds, now it's more like 3-5 minutes

That's odd. Could be a hardware issue.

data connectivity issue

has anyone else experienced problems when turning off the mobile data and the phone not reconnecting properly.
i disconnect mobile data during the day to extend my battery. When I do this, sometimes it reconnects properly, and other times i am not able to receive calls/make calls or send/receive text messages. The phone still shows in 4g and has full bars, but im not able to figure out its not reconnected until i try to make a call, which it doesnt allow me to do.
This is my second sgs3 now since my first did the exact same thing, and i thought it was just a faulty phone. anyone else experience this?
help please.

I had similar issues and I have called at&t 2 times. They asked me to turn my phone off for 5 minutes after which they re inserted my phone id in lte mapping... And they told me to call back if any similar issues arise

Calling issues

Just wanted to see if anyone else has been experiencing this or maybe knows a way to fix this. I have 2 issues with the phone calling on this phone. I had the 925T since launch and never had an issue with it. ever since i sent it in for repair, I've had a strange issue. Fist one is dialing out. When attemting to make a call, it takes anywhere from 3 seconds to 40 seconds before the call actually gets connected. this is highly annoying as i dial a number and it feels like forever before the call actually connects. my other issue is after the phon ehas been one for a few hours, I dont get any incoming calls. the phone will not show me any incoming calls at all so I don't even know when someone calls me. Ive tried everything i can. tried changing sim cards, updated the bootloader and modem, tried different roms, kernels, stock odin, everything. and its the same story no matter what I do. Anyone Have an idea of what it could be? It only works well after a fresh reboot. calls works without issues. hours later, problem comes back

I've had the same exact problem but I attributed it to using an AT&T Sim card on an unlocked T Mobile phone.
I've now rooted and installed Xtrostolite Rom with latest modem and bootloader. I've yet to have any issues. Good luck.

Anyone else have this issue?

I have this issue. It seems if i leave wifi off i do not ever have this issue. I live in a crappy coverage area so i have to have wifi on at home. I just reboot when i leave. I hate this phone....

You think the problem is WiFi related?

Yes. If i leave wifi off i never have the issue.

Still is happening. whether I have wifi on or off it always happens. It seem,s to be an issue related to VoLTE. When I turn LTE off, the issue dissapears. Updated baseband and bootloader to latest version and issue is still there. Have a custom rom and the issue is still there. go back to the tmobile rom and the issue is still there. thinkiing of going back to a tmobile firmware and turning off VoLTE in the firware then reflashing back to custom rom and seeing if that helps. if not, im selling the phone and getting the F version of the regular S6 and calling it a day. im done with carrier branded phones.

Interesting enough I haven't had this issue in the last 3 to 4 days. I wonder if it is AT&T related.

I have this issue. All the time. Unlocked from tmo, using straight talk at&t. This phone is the worst.

Anyone not on AT&T network having this issue?
I wonder if flashing the AT&T modem on TMO model will help.

Maybe you should get a phone from att.
If att service is better than tmobile then maybe there phone is better than tmobile's phone.

I've been able to switch between carriers on any phone that has the supported bands since the galaxy s2. The issue is with this phone. My mistake in buying it.

Please help!

same thing here its unbearable, using latest unibase and xtrestolite

I have tried a few roms and a few kernels. I have tried differ apns but att Sim in this phone doesn't work like it should. I was going to get a TMOBILE note 5 to use on att but now I know it's not worth the risk.

@stu5797, yea man, I wish I had a solution. I'm happy it's not just me, but pretty bummed that there seems to be no answer other than it just doesn't work properly.

I've noticed the issue only happens during peak hours. Can anyone confirm?

I was having similar problems after the 5.1.1 update so after a few troubleshooting sessions with TMO, they sent me a new phone. 2 weeks now and no more problems. First phone that I have not rooted and flashed..... I was also told by a store rep that a lot of people were having issues since TMO is upgrading towers for 12 band.

Are you still having this issue? I have the same issue and the same phone but mine is unlocked and working on cricket network. So yeah same problem taking forever to connect a call and no receiving calls mos of the time. No ring no notification of missing call. I been doing some research and find a temporary fix. Try going to settings -mobile networks and switch from lte/wcdma/gsm to wcdma/gsm or gsm only. But before do a test. Turn off data and try to make a call see how fast it connects then have someone to call your phone. If it works then this trick will work for you. Of course you gotta sacrifices lte speed . Basically having 4g only but at least will fix your calls. These problems seem to ve related to volte i been trying to disable it but there is no such option under phone app setting. I just dont have it. (I cann show some screen shots) so if someone knows a secret code or app whatever to turn it off i will appreciate it. My phone is a t mobile galaxy s6 edge.

Didn't work for me. I turn off data and I still have to wait until the call goes through

[HELP] Recently, GPS wont work on some apps without sim inserted

I thought it may have been an update to my app (Amazon Flex), so I rolled back to a previously saved version, but the issue persisted.
If I dont have a sim in the phone, the app will say that it cant get an accurate GPS location. Tried rebooting, airplane mode, clearing and redownloading the AGPS data.
The only thing that makes it work is inserting a sim card.
This device has LTE issues for me, so I prefer to just leave it on WIFI tethered to another device. But due to this issue, I have to remove the sim from my primary phone to make this phones GPS work.

Still havent figured out whats going on. I've just left the sim in there. If I can at least get the LTE to stay on consistently, then I'll be happy.
Scouring the forums right now trying to find posts relevant to me.

Network connection drops and squeeze for assistant stops working

Just checking to see if I am the only one having these issues.
I have the 3 XL on ATT, and I randomly have no internet access over mobile data, even though the notification shows LTE and decent signal strength. Screenshots attached to show what I'm talking about. This has happened about 4 or 5 times since I received the phone a few weeks ago. I went to ATT and got a brand new sim, thinking that my old sim may have been going bad, but that did nothing. Only way to get the mobile network connection working again is to reboot the phone.
I have also noticed a few times that the squeeze for google assistant feature will stop working, and I have to reboot the phone to get it working again. Anyone suggestions? I am leaning towards just doing a factory reset this weekend, but I would like to avoid that if possible.
Thanks

dont know about the edge squeeze assisit not working (i use edge sense module and app) but i have to reboot or go into airplane mode to get data to work when i get the x. maybe using a different apn would help... im on att too

AT&T issues
This is now a problem for me. I have to put my phone in airplane and then back to lte at least once a day in order to get mobile data working again. I'm not really sure if it's a network issue or a phone issue.

Issue for me here too, but I'm in Australia on Telstra network.
