I have Samsung A32 5g SM-A326U from AT&T, I got the unlock code from them.
1. I have 2 different carrier SIM cards, the 1st SIM (STC) can't make and receive calls at all, but internet and SMS are working fine..!!
and the 2nd SIM (MOBILY) internet connection is not stable at all and keep disconnecting every 5 minutes and I have to restart or put airplane mode for some times to reset the network...!!
2. Also there in NO 5g signal at all in all locations for both carriers. ( 5g working fine in other mobiles)
NOTE: Both SIM cards working fine in my NOTE 8.
I tried factory reset, still same issue.
any suggestion will be appreciated
Thanks
Try flashing stock and let's see what would happen.

Hi,
Recently got a Koodo GTi9020A and have tried to use it in the UK with a 3 Sim.
The phone gets a full 3G signal, data and internet work, however there is a problem with making calls when using the 3G signal.
When the phone is turned on I can make one call to a landline, however if I hang up and dial again there is silence. Calls to other mobiles are scrambled.
I have spoken to Google and have been told that the Canadian software will not work with a UK Sim and the phone will need flashed with UK software.
The phone is therefore 'locked' to the Canadian networks. The lady from Google mentioned that a fully unlocked phone would be more expensive!
Any advice appreciated.
Thanks.
Hi guys,
I bought my G930FD about a month ago and I have started running into a rather annoying problem:
it seems that tethering only works if SIM1 is use for the data connection. If one attempts to use SIM2 for data and then tether (regardless if one uses WiFi, Bluetooth or USB), the connected PC is unable to use the internet connection. I tried several ROMs (including unadulterated G930FD stock) and SIM-cards (Vodafone NL, Base DE and NTT Docomo JP). Nothing seems to help, so I am now asking you guys. Is there anybody who has any idea how to fix this? I recon the trouble lies somewhere in the tether settings that doesn't get properly switched to SIM2 data. So any help would be greatly appreciated.
What if you're on SIM 2 but turn data off for SIM 1? (or turn off SIM 1 completely)
I'm experiencing the same problem. On a dual sim S7 edge and when tethering the connected system just can't get on the internet. Also switching the sims to other slots doesn't seem to work. The strange thing is that tethering does work on one of the sims but only when roaming...
Same problem! Any solution?
Sorry to ressurect this thread, but I just bought a J7 dual-sim and am having the same problem (hotspot working only with the SIM that is roaming, but never with the non-roaming SIM). Did anyone find a solution? This is extremely annoying, if it cannot be fixed the J7 is clearly very poorly made.
I m using my G930FD (Dual SIM) phone from may 2016. On marshmallow i didn t have any problem. After I switched to nougat, problems occurred with reception on 4G.
Where I live, the phone uses the Band 20 (800Mhz) and working both Sim cards without any issue, everything OK.
At my workplace LTE uses Band 3 (1800Mhz) appear the problems. After a random period of time, SIM1 unusable switch off from network and get "No service, emergency call only". Airplane switch ON/OFF, and SIM 1 functional again.
You can see the actually used channel dialing *#0011#
I think the problem is related to nougat modem, and only on BAND 3. Tried 4-5 different nougat modems, but no lucky.
TEMPORARY SOLUTION: flashed back marshmallow 6.0.1 modem G930FXXU1BPL6 and now seems ok.
Anyone else have this problem?

I'm not using the dual SIM version but the normal one (G930F). I also have some issues with 4G data dropping to EDGE/GPRS after a call and occasional "Emergency calls only" message. This would either require a restart or a switch in Mobile data type (LTE/3G/2G) and revert back for it to be fixed. I've also tried flashing different modems like you've done. I initally had the NEE region in Marshmallow (which I remember had the same issue, but less frequent) and then I updated to Nougat by flashing the BTU firmware.
I will try the modem that you have mentioned, hope it all gets fixed after that Thanks :good:
Hi
Maybe you can help me.
I used my M808 2 years. In 2 days i can't call and sms and don't have internet when i have 3G or 4G. When i force 2G i can call and sms. In 3G i can see range but i cant call to anybody.
Do you have idea how i can fix it?
I done hard reset and nothing, I try my SIM card in other smartphone and there i had 4G ok.
Will Change rom help?

This could be caused by a few things.
1. Hardware fault.
2. Your carrier (SIM Provider) switched to a none supported band or bands. The M808 does not support LTE band 20 (800mhz) which is common in Europe
Supported Network Bands:
(2G) GSM 850/900/1800/1900MHz
(3G) WCDMA 850/900/1900/2100MHz
(4G) FDD-LTE B1/B3/B7/B8/B28
3. APN settings although this would not affect voice calls
4. Your carrier Decided to block your phone by IMEI from using anything other than 2G and yes they do sometimes do this O2 did it to me some years ago now with absolutely no warning or reason given so I will never ever use them again the arrogant s****
5. Duplicate IMEI someone is using a phone with the same IMEI as yours on the same network. This can cause all kinds of strange stuff to happen. Again happened to me when I restored the incorrect backup. Both mine and my sons phone ended up with the same IMEI . It took ages to work out what was going on with that one
I would suggest you first try another sim card from another provider that use's the supported bands for 4G (3UK) if in the UK it used to work fine on my Old M808.
I done some tests.
I put my sim card to other phone - everything is ok.
I put other provider sim card to my phone - only 2G is working properly.
I done flashing - no improvement.
Im afraid hardware fault.
Any more sugestions?

Bought phone from India, live here in Canada.
Just to confirm for clarity sakes.
Use an Indian Sim card here in Canada, and make a call here to some number for 5 minutes.
Switch sims to Fido (Canadian Network) no issues?
Confirming since this is the first time I have ever read/heard about the above.
Ideally, that should have been done when in India. Try, hopefully it still works
