Hi Guys,
My phone is on 9.0.3. I am using only 1 jio sim in phone. It works fine but in a day the volte sign disappears multiple times for about 40-60 seconds and then it comes back at it's own. During this period I am not able to make or receive calls but the internet works. I have another jio sim in my Galaxy phone and it works fine. Tried this sim in the other one and it works fine. Contacted jio, they checked the settings and told me to get in touch with op as everything is fine from their side. Any help?
Thanks

Hey guys, I picked up a T-mobile galaxy S3 over black friday, and have been trying to use it with wifi calling for the past few days. Here is what is happening: I updated to 4.1.1 as soon as I opened the package. I setup the phone and then tried wifi calling. It worked the fiirst call, but later when I put dial in the number, within 1-2 seconds I get a "Your call cannot completed as dailed" message. I couldn't even dial 611 for customer care, but I could call my voicemail.... So after talking to customer service, I was told a new sim card would likely fix the problem, so I went to a T-mo store and got a new sim. They tested it once there, and it worked for the first call. I got home and it was doing the same thing as before, telling me my call couldn't be completed as dialed. On a whim, I put my wife's postpaid T-mobile sim card into the S3, and lo and behold, it worked, every time, flawlessly. I switched my prepaid sim back into the phone and it reverted back to not working again. I called up T-mo and talked to someone who finally referred my case to some engineers, but its been 3 days and I haven't heard back.
If I lived in a place with a good T-mobile signal, I wouldn't care, but I get less than 1 bar, and my data is edge, so I kind of need wifi calling. I've noticed when first booting up with my prepaid sim, I sometimes get the Reg99 cannot connect erorr, and the Err01 "Invalid certificate" error. But then the wifi calling later shows connected with a blue phone symbol saying it is ready to make calls.
I can sometimes receive calls over the wifi, but I can never make calls, only to my voicemail. I find it odd though that my wife's postpaid sim works just fine, every time, but my prepaid doesn't. Even though they are both the latest sim model number TM9190 or whatever.
If anyone has any ideas or solutions to this, please let me know.

I'm guessing my issue is a very rare one. I don't really see Nything else on the forums about it. Anyone have any guesses? Or anything I can test.
Hello there,
Im getting trouble to get the dual sim working properly.
First of all my setup : OOS 3.2.7, rooted, some xposed modules, nothing fancy. Stock kernel
SIM1: Data SIM, o2 germany
SIM2: Just used to receive some texts, all APNs deleted, Carrier : Orange/Sosh France
In normal usage SIM1 is deactivated. In this case everything works flawlessly.
As soon as I activate SIM2 i run into trouble. I loose data on SIM1 almost instantly and the only way to recover it is usually a reboot.
When i loose data the "LTE"/"H"/"3g"/whatever icon disappears, data is still on in the settings.
I noticed that at least once both sims were connected on UMTS when it occured.
Any clue to keep my data connection working when both sim cards are active?
Thank you in advance
Just got a Moto Z Play and as part of it I'm switching to T-Mobile.
Got the phone a few days before the SIM card, so I put TWRP on, rooted it and put the 7.1.1 LineageOS rom on.
Thought everything was working fine. Internet works, everything seems stable. However, I can't make calls. Or rather I can make one call after a reboot and then nothing. The SIM info shows cellular network disconnected. Tried two sims.
Any ideas?

Just taking a shot but did you call T mobile and verify the Sims are activated.

I haven't contacted them yet. Oddly though internet works fine. So I think the SIM is good.
I did find that if I turn enhanced LTE off that calls work. So it seems like voLTE is what's broken. Possibly from the ROM.

I believe you're correct in assuming volte is broken in LOS, there on going discussions and yes you'll need to reboot after every call.
I would assume this goes for all custom ROMs (3 lol) for our MZP, as everyone has used alberto97 git to build from.
So I have used my S20 Ultra since March this year.
I've noticed that the cellular network just "sleeps" and doesn't receive calls/SMSes after some time of phone idling/usage on WiFi.
I tried googling and found many other users reporting similar issues, noticing also that it seems majority if not all are Exynos variant users (not based in US).
Personally, this is definitely not a telco provider issue as I have had this issue on my old SIM (which was working fine on my old phone) and new SIM that I recently got after switching providers to see if the issue went away.
For me, sometimes the calls come in a few minutes late, and then the phone rings but when picking up, the call just gets stuck because the other party is no longer calling.
This is particularly noticeable as due to mostly staying home during COVID-19.
Toggling flight mode to "wake" the cellular network makes the phone be able to receive calls again.

Lucky me. Didn't have this problem on my s20+ exynos

I also have this issue (S20+ exynos, dual sim). I use wifi at home/work and I had several missed calls and delayed text messages during this time.
Now I turned on the text alerts about the missed calls. At least when my phone connects again to the network I get these notifications.
I am also having this issue. People call and it rings out at their end but not at my end. Is there any fix?
Try switching the active number to slot 2. I tried it for a couple of days and I think it was better. I have switched back to slot 1 to monitor as I just got the ATE6 update and wanna see if it changed anything.
I had this issue and figured out what was causing it. You need to disable VoLTE if you are not registered to use this service on your carrier's network.

My sim cards are already registered to use VoLTE, my carrier notified me a few months ago about it.
I tried to disable VoLTE on both sim cards. It was OK for 2 weeks until now.
I got a new missed call notification text message and after 5 minutes a message from the caller.
Now I enabled VoLTE again for one sim card. Let's see if there will be more missed calls with this setting.
Hi everyone I was using LineageOS 17.1
I have 2 sim cards: One from JIO, a 4g only carrier and another from Vi (Vodafone) which has 2G/3G/4G. I flashed Lineageos first more than a year ago and everything was fine. But sometime around april this year SMS stopped working just for the JIO sim. Calling and Data work fine. I am not sure but i think I updated(17.1 -> 17.1) before this happened. Today i finally decided to investigate this. I tried the JIO SIM on another android phone as well as an iPhone and it works fine. but on my OP3T, it refuses to receive or send SMS. The Vi SIM doesn't seem to have any issues.
Another interesting sidenote is that if i remove the sim from the iPhone and put it in the OP3T, it doesn't work until i reboot the OP3T!
I tried updating to 18.1 today. It didn't solve the Issue. So currently I am on 18.1
Can someone help me figure out what the problem is?
