Hey friends,
I'm looking to take my Note 8 from Verizon to Tmobile. The problem I'm having at the moment is while on T-Mo's network all calls forward to voicemail, no problem with making outgoing calls. Spoke at length with Tech support and we ran a test and did ##21# to deactivate the unconditional call forwarding. The phone received a call immediately afterward, but after 5 minutes reverted back to forward all calls to voicemail. I have 2 note 8's from Verizon and both did the same thing. Brought over 2 iPhone SE's with no problem. In addition, the data drops completely during a call. The call will not connect until the data is dropped then the call beings to ring.
I tried first unrooted then rooted them as they both are V2 via SamFail. Any thoughts? Anyone experienced anything similar. Tech support from T-Mobile said that If the phone had a 2G Only option that the service would work fine. Weird... Regarding the root, should I flash a home_CSC from Tmobile?
Thanks in advance for those they respond. :good:

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.
Having issues from any of my sprint phones calling any landline number outbound. It will not ring and then says call failed after about 30-45 sec. I can call a mobile phone with no issue. Have tried all the usual troubleshooting updating profiles and prls on my 2 galaxy s6 and 2 iphone 6 phones to no avail. It is definitely something sprint side, but was wondering if you guys had any input/solutions on this. I am in one of the cities where they have a enabled carrier aggregation and am connected to band41 when trying to make calls with good signal.
Hey,
So I bought an LG G4 from Vodafone UK and unlocked it so i could use my Three sim card.
Weird thing is I can use Mobile Data and send/receive SMS if I am on 4G. The person who is calling me can hear the calling tone as if they were calling someone but I don't actually receive the call.
When I switch to 2G/3G it simply does not connect to the network.
I have done a factory reset and it did not fix the problem.
Any ideas?
Thanks
tl;dr : can't send/receive calls but can use data and send/receive sms (through 4G only)

Maybe you need to register your IMEI on the network? That's what I had to for At&t.
How would you go about doing that? Apart from manually searching for networks (I can see other carriers like O2, vodafone, EE, but I can't see my carrier Three ; the person living in the flat with me is on Three as well and they have no problem, so it's not a coverage issue. I have bought the phone from vodafone, unlocked it and trying to use it with Three).
Do I have to call Three for this IMEI registration or..?
Thanks

Best bet will be calling your service prover and have them register it. I had to call At&t and have them register my IMEI since I couldn't use internet or make calls.
Just had a long chat over the phone with them and in the end he said the 'engineers' found a 'problem' on their end and it should be fixed in @5 days. He didn't want to mention what problem or how / why it happened. Oh well fingers crossed.
Thanks!
update : so after about 4 calls with customer service (across 3 weeks) and 2 trips to the 'Three' store i'm basically stuck and would need your help guys.
backstory : I've contacted them once at the start of January and they said they found the issue and they will fix it by 7th of January which didn't Happen. On 7th of January they said they are sorry and it will be fixed by 14th of January which didn't happen either. After that I received a message that the problem was fixed and if i had any other issues I should contact them, which I did because the problem was not solved. Yesterday I went to the shop again and the 'tech' guy told me that it should be working and he gave me a new sim card just to be sure, and if that didn't work he said call customer support and ask for contract cancellation. Today I got called by customer service and I have told them that it still doesn't work and I'm paying for something I can't use and I've been told to request contract cancellation which they didn't believe and said I have to pay the rest of the contract length in order to cancel, which is absurd. I went again to the shop and the new customer service person that was assigned to me said they don't have any tech people and she seemed she didn't believe when i said i talked to one the day before. She tested the sim on their phones and it worked and also she took my phone "in the back (strange cause she said they don't have any tech)" and said I had my phone set to 2G (which I didn't, it was set to 2G/3G) and that that was the problem. strangely, for that split moment i had one bar for 3g and the call went through. Straight after that phone stopped working (it was just that small area in which it worked). I told her that that's not the problem and she's like "welp you didn't make your contract at the store, you made it online so I can't help you , you have to call customer service". So I'm basically stuck with a contract which I can't use and I have no idea what to do.
problem : I cannot register to the Three network (only in small random areas, few of them) but I have no problems with other SIM cards from other Carriers (Orange, EE, Vodafone, O2). I have bought the phone from vodafone and unlocked it and last time customer service told me they can't give support to phones that were not bought from their store. So I'm stuck here with a phone contract which I can not use to make or receive calls, but I can use the mobile data and send receive texts. I am considering rooting it and puting a custom ROM , although I'm not sure if that would fix the problems (maybe issues with certain bandwiths?.
Any help or ideas much appreciated!
Same problem here
Hi all. Same problem here but different issue.
Origin : G4 buy used on November. IMEI fully working and not blacklisted (calling my french phone provider this morning, it tell me that's IMEI is ok and phone not stollen and it try to repair remotly my carrier but didn't work)
Problem : Fully working since i picked up a call and answer ... and then when the call is finish i tried to call someone 10 minutes after and totally loose signal(connection) (Orange/Sosh)
What i've maid before : Playing a lot @ a boring but adictive game. High temperature since 3 days because i play a lot but temperature decrease when i stop playing.
I've used a legal app to record a patern and make some actions without my intervention (RepetiTouch Free (root)) to make races in the game.
That's all ! No drop, no hit, nothing ! Just playing, having a call, hang off and then want to make an other call and nothing.
Since the last 6 hours : Signal ok - Data ok (can go on internet / GAPPS etc..) - CAN receive and send SMS (i've don't trie MMS) !!! but .... can't receive and can't send any call.
I was on Genesys 3.5 and i've update to 3.7 when i see the problem, believing that's it will fixe the issue but ... no ....
Formating and going to stock ROM but with root SU etc..... Can't receive and send call too ....
I'm going to back to stock with KDZ .... but i really believe that's it will not work .....
AND .... to finish and kill my joy .... i've unlock bootloader with LG tools since 2 month .....so my phone is no longer under warranty.
My SIM card work on others phones ... other sim cards didn't work in my phone ....
If anyone have this issue ... please tell us
Sorry bro cant help you here. Never heard of that problem before but my idea is that you should refund that phone back to Vodafone UK.
I have a HTC One M8, AT&T, TWRP recovery, flashed and rooted with ICE 8.2.2; SuperSu.
When I am connected to 4G/LTE and someone calls me, it rings on their end but my phone does nothing. I checked my IMEI and see LTE is supported. When I switch my mobile network from 2G/3G/4G (auto) to 2G/3G (auto), it connects (H, H+ icon) and my phone receives incoming phone calls. My SIM card does not mention "4G" or "LTE". I have yet to try the SIM in another phone yet but plan to tonight.
Just to help me out with my thought process on figuring out the issue I'm going to think out loud for a second:
Put my SIM in another phone and make sure 4G/LTE is on, check if it receives calls. If it works, the issue is my phone or ROM. If it doesn't work, SIM card is the issue.
Also, from what I understand, phones on 4G switch to 3G when a call comes in and my phone may not be doing that. Is there a fix for this?
EDIT: As additional info, I am able to make outgoing calls without issue on 4G.
Are you actually using AT&T as your cell provider?
Yes, and I made sure my APN settings are correct.
It's a known issue. AT&T's implementation of Voice over LTE (VoLTE) which they call "HD Voice" for some reason interferes with voice calls on custom ROMs on this device.
No real fix, aside from calling AT&T and asking them to turn off the HD Voice feature of your account. May need to ask for a 2nd Tier tech support to do it. Others here have posted they had to do that (and 1st Tier either had not clue what they were talking about, or wrongly claimed it can't be turned off).

Awesome. Thank you!
EDIT: Just finished working through the issue with an AT&T rep through online chat. Had me turn off my phone, disabled it on their end, and turned it back on. Did a test call and sure enough 4g switches to 3g as the call comes in and switches back afterwards. Problem Solved!
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.
