"Can't be completed as dialed" using Tmobile prepaid

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.

AT&T Incoming Call to Voicemail. AT&T users I need you help

I need AT&T users to test this for me. On my wife's 5X on AT&T it seems like every call goes to voicemail first but if you call back it will ring. Could someone test and see if they are getting this? If not do you know how to fix? Thanks

I'm receiving calls just fine on mine. I'm on att trough net10 though so I'm not sure if that's different.

I'm on AT&T and no trouble receiving calls for me.

So odd, spent some time with att on the phone. My suspicion is that when a call is coming in since we do not have volte it drops to h+ which has a weak signal and goes to vm... When will att allow volte for not att phones?! Thanks all

if you haven't yet, I would reset/flash as new without sim and then reinsert sim and go through setup as stock. No google voice or hangouts or forwarding and see what happens.
my 5x hadoffs between lte and h+ happen a bit depending where I am at my house, and I don't have any problems. MY last thought is check airplane and do not dusturb, but still. I would start at the beginning.
maybe you've already done this.

I also have AT&T, and no problems receiving phone calls. I had to get a new SIM card when I got the phone (nano SIM to replace the micro SIM that I had used in my old Nexus 5). I noticed that the APN that was the default on this phone is "ATT Nextgenphone", instead of the "ATT Phone" APN that my old Nexus 5 used. The old "ATT Phone" still shows up as an option, but I figured that I'd just leave it as is (on the "ATT Nextgenphone" APN. I don't know much about it, but from googling around, I believe that this APN is for VoLTE. (http://developer.att.com/technical-library/apns/apn-descriptions-and-characteristics). Might want to check APN settings and see if you can change it to Nextgenphone.

Thanks but hers is also on that apn. I'm going to send it back to google and try a different unit. According to everything I have read VOLTE is only available on AT&T if you have their specific phones. I hope that changes soon but if I'm wrong and you are getting VOLTE please tell me. Of course the easiest way to test is to turn off wifi and while you are on LTE have someone call you and see if it drops to H or H+ or if it stays on LTE. Thanks!

I am am also having this same issue. People trying to call me are getting call failed messages and they have to dial 5 or 6 times before the call actually connects. I did you get a solution?

No network when making or receiving calls

Hello,
My motherboard went to heaven and I bought a lg g3 with a broken screen from a local ad site. Switched motherboards and everything was fine until I tried to make a call as it losses the network and does not allow me to make or receive calls. Oddly enough I have 4g data and everything else works.
When I switch network to only 2G or only 3G the phone losses the network and I have no data. If I put "automatically switch between 2G, 3G, 4G" I have 4G data but I can not make or receive calls.
I installed xposed and imei changer thinking that I had bought a stolen phone, changed the imei number and still no network.
It does not matter if I am on stock or any other rom. I thought about flashing different modems but I guess it would be wasting my time.
If anybody could help I´d be grateful.

I assume you have checked the APN settings, the motherboard matches your variant and you reflashed the modem. Can you test it with another SIM card? Maybe the new "motherboard" is also faulty...

I have now checked APN settings and they are fine but I dont see why they would affect the problem, as I said I do have data (4G), the motherboard matches my variant and I have now reflashed the modem (just in case) and it does not work (thanks for the suggestion). I have tested it with another sim card, no success.
Any more ideas?

Calls and texts not working.

Hello everyone,
I'm having a bizarre problem that no one can seem to fix. I have an unlocked AT&T branded Note 10+. I used it on my preferred service, MetroPCS.
A couple of weeks ago it stopped receiving or allowing me to make calls. The signal showed full bars and everything else worked fine. After attempting to fix it and failing I switched providers and went to Verizon.
Bizarrely, my phone will not work on prepaid vzw but did work on a post paid so I signed up. Everything phone related worked. It was however very expensive.
Seeing my phone work on a network made me think my phone wasn't the issue so I went back to my preferred network.
Now the situation is this: With a metro sim inserted I show 4G LTE icon but no bars, instead it's just a circle with a line thru it. In this state I have full data but now calls and texts don't work. When I try to make a call the 4G icon disappears and full signal bars replace the circle with the line.
I tried metro tech support, they are no help at all. So I called Samsung. They informed me that my device is still locked. That can't be true as I've used it on two networks that weren't AT&T. However, rather than writing them off I went back to VZW and had a worker insert his sim into my phone and it worked flawlessly, just reassuring me that my device is unlocked.
This device, other than being unlocked is unmodified and had been used in a 100% stock state. Is there anyone here who can please direct me to a solution for this issue?
Edit: I have tried switching to new metro sim cards. Reset my apns and network settings. I even tried a full factory reset.

You just proved either the SIM or the account is the issue.

I would agree. I should've included that I have tried 3 new metro sim cards, with the same result.
However, please tell me more about how this could be an account issue? Because that could lead me down a path to a resolution. Thank you

Question Problem to use Motorola Edge X30 in USA

Hello, first of all I want to say that my native language is Spanish and I am using the Google translator to write this, so there may be writing errors and apologize.
Buy a motorola edge x30 and the imported import from China. The phone is unlocked to be used with GSM networks from anywhere in the world. When I bought it, I was with Metro PCS but in Metro I was told that the phone was not compatible with the 3G networks of them. After that I started to investigate and find a web page called kimovil and there I saw that the edge x30 was compatible in the USA with all the networks of 3 suppliers: Cricket, AT & T and T-Mobile: I choose to use change to metro by T-Mobile.
Immediately I left the T-Mobile store after making the change I have tried and could receive and send SMS, receive and make calls, and get access to the Internet without any problem. After a couple of hours of having activated services with T-Mobile, the phone could not or receive more calls (the Internet and SMS continue to work normally, the problem is only with calls). When I try to call someone, the call is not done and says "Hanging Up". I tried everything: Factory Reset, Networks Reset, modify network configuration, everything ... and I can not solve the problem. I went to T-Mobile to tell you about my problem and they tell me that the problem is not them but my phone.
If anyone knows how to solve this problem, I would greatly appreciate the help because I feel frustrated. Thanks

I have MOTO EDGE x30 with T-Mobile. Work perfectly. Check the SIM setting.

Good afternoon. I already managed to use the Edge X30 with the T-Mobile network. You just had to put the network selector on automatic so that you can use 5G, LTE, 3G and 2G as you see fit. The problem is that I realized that the phone only calls and receives calls in 3G and 2G, which limits not only the quality of the calls but also limits your coverage to be able to make calls since you can only make them in 3G and 2G . You who also use T-Mobile, does the same thing happen to you?

I'm not sure, but it supports 5G in N1/N3/N5/N7/N8/N20/N28/N38/N41/N78 and 4G in B1/B2/B3/B4/B5/B7/B8/B12/B17/B34/B38/B39/B40/B41. or check volte settings.

you may try to install "carrier services" app by google from the play store. it solves some of my problem with data connection.

Yes I have the same issue. Whenever I make or receive voice calls, the phone falls back from LTE to 2G. I looked everywhere on the phone for 'VOLTE' settings but could not find it. Does VOLTE work for this phone on Tmobile? Very frustrating.

Has anyone been able to find the solution for the calls switching back to 2g? I love the phone but this is extremely annoying. I'm on T-mobile. Thank you
