Yesterday i recived a replacement phone from asurion, when i got it and after it was activated i let it update to 4.0.4 and then i rooted it. As soon as i got the phone i put it on wifi, this should have been said first, do i have no idea if my lte worked before. I didnt notice untill i tried to launch pandora at work this morning, in info it shows i still have the lte baseband, i did swap from global to lte/cdma and that didnt help. I used *#*#4636#*#* to change through all the service modes and onl cdma only and evdo only work in cdma i have 1x service and can call and txt people in evdo i have 3g but can only use the internet. Also i used razrs edge to root.
Any ideas?
Note in 3 hours if i have no reply ill flash back to 2.3.6, where it was when i got it, and try again with no wifi so ill know if its hardware.

my friend tom got his galaxy s like two months ago. he has a even more plus plan with unlimited everything on tmobile and he used that in a iphone 3g for a year with no problems and he could roam with no issues on att.
with his new vibrant its not working! it takes forever to try to connect then gives a error. the sim should be good since it roams in two other unlocked phones..
for the note, his phone IS unlocked... that was the first thing we thought of..
the error is: unable to select network.. your sim card is not allowed to connect to this network
this phone is a quadband phone so it should work.. we have put a att legit iphone sim in it and it works great.. what gives? why can't he roam on this new phone when other phones do? running bionix rom.. have tried updates, wondering if anyone has any opinions or info
we've already tried changing network settings with *#0011#, gone into service mode *#*#197328640#*#* with no luck
edit: we've tried not allowing the phone to connect to our local att 3G band (1900) and use all other bands again with no luck. the phone connects to canada's rogers network tho.. weird..
anyone check this out yet?? anyone got it workin? any reports would be killer ...
we have tried more settings through service mode still with no luck. when we specify certain bands and leaving the att 3G local band unchecked, it will not hop on T-mobile with the setting! Crazy! not sure if it's the rom, radio version or kernel but we will keep tweaking and posting results.. if anyone is having this issue or has concerns any posts or signs of life would be cool lol
Same issue
Unfortunately, I don't have a solution, but I've been working on this same issue since september. I originally contacted tmo about the problem to see if they somehow hadn't provisioned my phone/account for roaming. Needless to say they were not much help. They suggested I exchange the phone for a new one, which I did, and I still have the same problem.
I'm in a rural area of california where tmo has roaming on att towers. My girl has tmo service with a different samsung phone and she can roam on att just fine. She can send/receive calls and text. I even put my sim in her phone, and it works, so I've pretty much narrowed the problem down to an issue with the vibrant itself.
My phone is not unlocked, so we've ruled that out. I'm running bionix fusion with ji2 modem now, but I've had the issue with the stock phone before ji6, and after ji6 ota. I've tried messing around with the service menu the same as you, and I haven't got anywhere either.
I have been able to get the phone to at least lock on to att by adding the apn internet2.voicestream.com, and it will get past the "not registered on network" message. Unfortunately, it won't complete a call or send a message, it just times out after about 15 seconds and drops back to the previous menu (depending on whether I tried to dial out of contacts, the call log, or the dialer). But it does not give me an error message, it behaves as if the call connected and immediately hung up.
I had given up on it for the past couple weeks, but I have time now to try and work it again. Let me know if you've gotten anywhere, and I'll do the same.
The fix is: when you're in an att roam area, set your phone to gsm 850 only via the service menu. If your phone doesn't auto lock on the att network, search for available networks and choose att. After that you should be able to send and receive calls and texts.
after yet some more messing around, still no luck. it's clearly a thing with tmobile not allowing roaming..... because i read many threads off the gooooogle that say tmobile is pretty much going away and any "contractless" plans don't have roaming so they don't lose money....
dickheads. at least he's grandfathered in with a good unlimited everything plan tho..
even if all this said, if anyone finds any info out post!
the other day i was out of tmobiles network coverage and on att voice and edge not 3g. i live in texas
this is with a stock vibrant jI6
tried the app RoamControl with no luck. it uses different tmobile bands when in "roam only" mode. anyone have any luck yet?
For some weird reason, ever since i got my GS3, i lost LTE. Its odd because i come straight from the skyrocket so i already had the lte data. But since i got the GS3, my phone can only connect to 4G (NO, 4G is not LTE, its H+). So i called rogers tech support, i spent about 4 hours with them, making tests, getting transfered to level 2, then to customer service to make sure i had an lte data plan...finally they told me your phone is broken to get a new one. So i go to rogers, they give me a brand new GS3, same damn thing...only getting 4G. We tried 3 different sim cards, nothing.
Then i call back rogers, they transfer me to the "above level 2" which they told me is the master departement. They guy tells me they will emulate my sim card in their lab with a GS3 they have...but nothing. All settings seemed right, APN and everything was good, so they finally opened a master ticket.
But for some reason, i dont beleive i'll get a call back anytime soon, so anybody might have any suggestions?? I'l fully stock, not yet rooted
Try performing a manual network search, then select Rogers to have it manually "Register" on the network.
For some odd reason, I had the same problem as yours, but after manually registering, LTE was back on, I switched it back to Auto after
check the sim card, there is also a chance that they gave you a 4g sim card and not an LTE one (bell did this to me)
If its LTE then go to the dialer and press *#2263# choose LTE and then LTE all (when you are in an LTE area) when it connects to LTE data do the same thing again but select automatic.

euff yeah, i think i would have checked for the lte sim card in the first place. As i said, we tried 3 different ones.
ill try that thx
Well selecting lte bands manually didnt work.
so then the sim does say LTE on it and not something like 4g? outside of manually selecting and waiting. I'm not sure what else. Maybe try getting them to give you a different sim and test in person. wish i could be of more help.

I already said that when they gave me the phone we tested 3 different sims. Same result. The only way i could isolate the problem is to have a person with a working GS3 on rogers give me their sim
I have never seen LTE when passing through an LTE area. Often I get knocked down to Edge while in Vancouver. No LTE where I live, bus something seems wrong. I was thinking of shutting off the 3g in network settings to see if that helps.
I am new to Rogers and not use to getting bumped down to Edge, as Telus only has a 4G network. Does this happen regularly, or is it a phone issue?
I've searched and didn't find any thread with this kind of issue specifically. I have a Verizon Galaxy S4 that doesn't seem to like GSM SIM cards; it looks like it is not GSM unlocked. I have tried every trick to get it to switch to GSM but it doesn't. I have flashed the same version firmware it came with (ME7) just to be certain it's factory restored, and also updated to MK2, yet no GSM. It sees the SIM card but doesn't show a signal, even when I manually switch to GSM/UMTS. I have programmed a CDMA number on it manually then tried the GSM switch again, yet no GSM signal. It sees CDMA signal fine though and can even make calls on CDMA. I even had to check the MEID/IMEI and it came back clean so I'm just surprised at all this. I have done this before successfully on a Verizon S3 and it worked well, how come the S4 has refused to work on GSM?
Please help, anyone?
Did you input APN's?
I thought APN settings had to do with data. I will do that now. I'm willing to try anything now.
Thanks.
I am having the same issue with a couple s4s from verizon as well. Checked the IMEI/MEID and they come up clean but they will not catch a signal with a gsm SIM card. I have tried several active AT&T and T-mobile SIM cards in the phones with the same results, no service/signal. Very strange as I have never had an issue with verizon S4s working on AT&T or T-mobile. The weird thing is that with a verizon SIM they catch signal and 4G just fine. Toggled GSM/CDMA and put in APNs and still no luck. I'll keep trying to work this out but right now I am stuck.
I had the same problem here
My GT-I9505 Rom Stock 4.4.2 ZTO(Brazil) had the same problem about signal problem.
Everytime i lock my phone (turning off the screen), by the time i light it on (lock screen), immediatelly my phone turns the signal to "No service".
In this time, i need to wait 1-2 minutes to the phone turns okay. Just wait.
I search for a lot of solutions and didn't find anything.
Notice too that the problem appears only network 2-3g. 4G didn't have the problem.
I solved this problem after Lollipop update. The problem simple dissapear!
(Sorry my bad english)
i have a galaxy mega gt i9152 dual sim international phone. im runnin an att compatible straight talk sim, i have service, but mobile network type says edge2. really slow data. i have the correct apn settings. ive even been to att and they tried one of their sim cards and still couldnt figure it out. if i select gsm/wcdma auto connect it will show the high speed data logo but the data dont work at all, if i dial #*#*4636*#*# it says wcdma preffered, but im usin gsm networks, it wont let me change it to anything besides gsm only, but then its stuck on edge again. theres some other secret menu i tried to get into debug mode where there is supposudly a setting to lock it to 2g or 3g but when i dialed it just said USSD code running, and then displayed my phone number. it was rooted and unlocked when i got it, i flashed it with stock firmware, still had the same issue, i tried a few different countries of firmware, no difference, currently running the uae jellybean stock firmware. i tried calling samgsung and they said i have to call the country of orgin which i guess is india, so i got an international calling card that i guess cant make toll free international calls. so im at a roadblock, i know its gotta be something stupid but i cant figure it out, been messin with it for 2 weeks and searching forums till my eyes bleed, so im makin my own thread now.
so now that ya know my situation, what do i do, how do i get my fone to work on 3g
Hello friends .
I'm sorry I am writing because I english translation program .
I live in Turkey. S6edgeplus - 928v phone models came from abroad. but the phone does not open 4G - LTE in turkey. *#*#4636#*#* it says LTE ONLY do I do when the connection was severed, and the line was disconnected . I could not find a solution in turkey please help me . Thank you very much in advance
Go into setting then mobile network and set network mode to umts GSM lte. If you're trying to get 4g while on a call, I can't figure that out. It doesn't work for me neither when I use an att sim card in a Verizon phone. I can't get Internet while on a phone call.

Thank you for your interest . but according to my research yesterday 3-7-20 LTE bands in Europe . I do not have my phone with this band . I do wonder how do I install or installing the ? I use my phone that is not loaded
Same problem on tmobile on 5.0 I wonder if its a marshmallow problem too. IT only worked when i first switched from verizon to tmobile and had advanced calling enabled through verizon. Somehow it tricked tmobile or the phone into working with data and call? Since i did a factory reset though now with tmobile sim no luck Im waiting to update soon myself almost done downloading the update
