Hello,
Yesterday I updated my unlocked bell i747m S3 to 4.3.
I used it on rogers before with no issues regarding LTE connectivity.
However I did a factory reset on the phone before the upgrade, and after the upgrade I cannot find the LTE/HSPA setting instead I see LTE/WCDMA/GSM settings.
This phone was never rooted and I just updated through Samsung keys. Does anyone know a fix to this problem?
Thank You in advance,
Stas
Have you rang your carrier? This could be an issue with your APN settings.
I got this T999V samsung s3 phone with wind network , one of my friend took it to another country. He asked a technician to unlock this phone. Somehow he unlocked this phone to work in that country. When he got it back in Canada, its not picking up its original network which is wind.
I flashed stock rom (downloaded from sammobile for 4.4.2 T999V) , but still not getting wind network. Its working okay with rogers network but not with wind
Any advice
My friend brought an original refurbish Samsung N910v android version 5.01 which was working with GSM 2G if not 3G until when I tried to update to new version android v6.0.1. In the menu>setting>about when I checked first before anything it showed me N910 F v5.01 but in boot mode Odin it was N910v.The problem started when I just typed *#9090# the phone immediately started reboot loop. I have managed to unlock the boot loader and root the phone installed custom rom version 6.0.1 by Paul Pizz rom VRU2CPJ2.r-1 but still can not have 2G or 3G GSM network. Please help to revive the phone again whether it meant to go back to 5.0.1 that would work with gsm cause am full stack now.
Have you checked to ensure you have the APN information in place? I have a Galaxy Note 4 N910V now (just got it a few days ago) and when I put my T-Mobile SIM in it from the very first time I have to manually put in the APN data - on custom ROMs it's usually picked up and there automagically but not always so, my suggestion is that you check to make sure your APN information is currently there as it should be.
Settings - More - Cellular networks - Access Point Names - make sure the one you need to be using is selected and if it's not then you'll have to put that info in manually and save it.
As for the actual model number, take the battery out and see what the model number is on the sticker in the battery compartment area - if the sticker isn't there then it could be a device that someone has done some experimenting with because that info can be changed. The sticker should be there, of course, but sometimes people take 'em out when they're mucking around with stuff, who knows.
Initially the phone is from Verizon but was working on 2G ,3G GSM network with N910F firmware version 5.0.1.it was working on airtel network until when I wanted to update. May I have the Apn settings,please

The APN will be your network. Are trying to use Verizon? If so, you should have a spot to tic the VZWINTERNET. If not, then you have a sim card issue.
ziggy the how do i sort out the sim card issue ,Since phone says this sim card is not from verizon

Is the sim from verizon? If you have a good account go to a corporate store and have them give you a new one. It's free.
Also, what are your APN settings and I will compare to mine. Everything works on mine.
the fone I have came from china ,am in Africa and remember I told you it was working woth N910f firmware version 5.0.1.All am asking is there anyway I could make this fone work again on Gsm network, cause all it says after re flash is the card is not from verizon
I now rooted this n910v android version 5.1.1 still no network, am in Africa where there is 2G&3G GSM network, how would I make this fone to work again with the gsm network now that I rooted. On the network bar I get a circle with a cross ,how to make this work

- N910VVRU2CPJ2_FullFirmware_NoAboot<--- Full Framework with no aboot so you will not re-lock bootloader, but will unroot and restore back to 100% stock. once your on the full stock check if your connections are working fine, if they are then install custom rom, otherwise change the sim card
go in settings, connections and select network mode to global, should be fine
Good morning, I am running the latest Lineage 14.1 rom (14.1-20171204-Nightly-d2att) on the Samsung Galaxy S3 (SGH-I747) phone, this phone is rooted, running the latest TWRP (3.2.1.0) and the I747UCUFNJ2 baseband on this device, this device is fully rooted, and is SIM unlocked for use with any carrier, my carrier is T-Mobile.
Ever since installing this rom, and any roms higher than android 6.0 (I've ran CM 12, CM 12.1, CM 13, SlimKat, and AOSP roms), everything works perfectly except for my cellular data will not go higher than Edge (2G) and my complete cell connection will randomly disconnect for a few seconds then reconnect itself.
I've tried everything from changing the APN settings specified by T-Mobile for LTE connectivity, I've gotten a replacement SIM from T-Mobile, I'm lost at this point as to what the issue could be. According to T-Mobile I do have the BYOD option so unlike some carriers, the SIM is not supposed to be locked to a specific IMEI.
Does anyone have any idea what could be the issue and/or a solution to this? Is there a higher baseband that needs to be loaded to fix this that I'm not aware of?
Thanks for your help everyone.
The phone is also running the latest bootloader?
Yes it is.
I assume the cellular data works properly with a stock ROM.
Does the cellular data work with the sim in another phone? Cellular data works with another sim card in the s3?

first of all i shoud state im over in the UK using SKY mobile(02 signal). So I picked up a used S9 last week and every thing seemed ok but i could not understand why is would not update from android 8 to 9. it turns out is a grey import sm960u USA phone and would not update unless the orig carrier sim was in and i was in the usa. i checked its imei and belived it to be on sprint SPR and downloaded the latest firmware and installed via odin. Now the phone will now not connect to my 4G, i have now found out that Sprint uses CMDA and not GSM that i require in UK .Stupidly i did not check which frimware version the phone was running before flashing it. Is there a USA firmware i can install which will get me back on 4g, maybe without carrier bloatware. i understand that i cannot flash it with sm960f firmware but maybe able to use sm960u1 firmware as this is the plain unlocked version
