[Q] Wifi calling on T-mobile

Wifi calling recently disappeared on my HTC One S.
When I try to make a call over Wifi, I get the message "Your call can not be completed as dialed. Please check the number and try your call again. Or call 611..."
I get the same message when I call "611."
But, I can get my T-Mobile voice mail.
Called T-Mobile, representative said it was my phone. It's not.
I have really poor coverage at my home from T-Mobile. Wifi calling is very important. Something is happening with the system or my account, but T-Mobile is not responding. Argh.
Otherwise, I really like my HTC One S, though the lack of Jelly Bean is a pain.

Interesting: I RECEIVE calls via WiFi. In other words, when someone calls my T-Mob number, and I am "registered" as WiFi with the system, the call comes through my handset with no problem. But I can not make an outgoing call: "You call cannot be completed as dialed. Please…"
As far as I am concerned, this is a T-Mob or account issue that they have not attempted to resolve.

Wife had that problem before we registered her SIM. I wonder if your SIM has died or your account has been suspended. Worth a trip to the store for another SIM.

Going to a store for a new sim is my next step. Though you would think after two+ hours on the phone with T-MOBILE, someone would have been able to tell me if the account had been changed. They say no. The account isn't suspended or I would not be able to make calls out on the cell towers.

I am have the *exact* same problem you are.
I receive wi-fi calls. I can call my voice mail, but I can't call out and I can't even call 611. I get the "Call cannot be completed as dialed."
I've got an active ticket with T-mobile, they said to check back after 72 hours, after I had already waited 72 hours.
Here is the kicker though, that tells me it isn't my wifi, isp, or phone: These problems are on my prepaid $30 account. If I pop my wife's postpaid contract account, I have no problems at all, I can make and receive calls, no issues...
That there tells me it is a Tmobile problem. I also just had my SIM replaced three days ago. I was able to make one outbound wi-fi call before it returned to the previous behavior. According to my TMO CSR, my account is setup and provisioned for wifi calling..
Keep this thread updated if you have any fixes to report.

[Q] Outgoing call/text do not work on Kyocera Brigadier

Hi all,
I wanted to create a dedicated thread to what have been scatteredly reported by other users in various generic threads when unlocking the Kyocera Brigadier. Mine is rooted (4.4.2, software version 1.102VZ, Kernel 3.4.0-g42c25d8, Build #KOTH49H) with a T-Mobile plan. The original carrier for the device was Verizon. I applied that trick to unlock APN settings. It worked pretty well (I've used kingroot instead of debloater). The Data (4G LTE) is now blazing fast and I can receive call and text messages. However, I can't make outgoing call/text. Below are some details:
Outgoing call: The phone application continuously indicates "CALLING..." but it is stuck there. If this is the first call after a reboot I also have the message "Error while searching for network". Then, I try to tap the "End Call" button but that do not close the phone app. The only way to unfreeze the app is to wait for an incoming call. About 1 restart out of 10 gives the error message "Unfortunately the process com.android.phone has stopped".
Outgoing text message: I systematically get the Error "Cause Code 0"
A factory reset do not solve the issue.
I would be very gratefull if a pro could help.

Not getting a lot of help on this, eh? I have the same problem with mine, I wish I had done more research before I bought the phone. I guess all I can do now is put the paperweight back in the box until either someone makes a rom for it or i figure out how to do it.

is your 4g lte is t-mobile's or else? what band is t-mobile's 4g?
did you try 3g or global and tested call/sms?
im outside usa my local sim is working on 3g out/coming calls and sms are fine but no 4g yet....
i hope someone will help you

I am on the Rogers network in Ontario, Canada. Wireless internet works perfectly, I get 4g, and can receive calls and texts, but I am unable to send either. Rogers was no help, they said it was a software issue. Downloading different phone and texting apps did nothing. The bloody wireless companies locking phones down is a complete pain in the ass.

Problems Handling Phone Calls (Call Waiting, 3 way, etc.) Verizon S5 on AT&T Network

Problems Handling Phone Calls (Call Waiting, 3 way, etc.) Verizon S5 on AT&T Network
recently bought a used Verizon Galaxy S5 (SM-G900V). It came with the lollipop OS. My service provider is H2O wireless (on the AT&T Network. From the outset, I had problems with phone calls, text messaging.
1. When I'm in a call, I'm not able to dial (Like to enter numbers for automated systems).
*I solved this one by going to:
settings>applications>call>
Scroll down to DTMF tones and change setting to long.
2. When I'm in a call, I'm not able to click over to calls on call waiting. When I do try to click over, I still hear the original call for a few seconds and then both calls drop and I get an error message that says "no sim or invalid sim". If I don't answer the call, both calls drop and I get the same message. The same thing happens if a try to make a 3 way call.
3. If someone calls me and I try to call them back, the call redirects to turn it into an international call and the call doesn't go through.
*I solved this using an app called prefixer
4. If I try to text message someone who called me, I get an error message back saying the phone number is invalid.
I figured I would have to root my phone to be able to make some custom changes. I first had to downgrade to kitkat (android 4.4.2) and root it and then upgrade with root using some very helpful posts and resources found on this site (thanks). When I downgraded, problems 1 and 2 went away (for number 1, I had to change my network mode, but that solution didn't work when I went back to lollipop). After upgrading beack to lollipop, all of these problems were there, though I was able to resolve 2 of them, the other 2 are problematic.
I think theres a problem with the way the phone is handling the AT&T network signal since they have a different type of network from verizon but i don't know.
I'm will in try to install a custom ROM, change settings in service mode, etc. I just haven't come accross any info to point me towards the right instructions. Alternatively, I may trade or sell this phone ant get an AT&T based phone. What do you suggest?

some phone callers are always reaching disconnected message to my phone

I am looking for some information regarding a problem I am experiencing with my phone, I have 3 questions regarding it. I have stated them at the end of this lengthy post.
My phone is zte grand x2 model z850 and android build is 5.1, carrier is pcmobile in Canada.
The problem is that my android phone seems to work OK and receives calls correctly, but my doctor office, hospial booking office, and phones belonging to my workplace receive a tone followed by some type of reaching a disconnected number. My phone calling log shows no record of calls being received to phone.
The troubleshooting steps are sent email to pcmobile and received response to do a battery reset, pull out battery and sim card for at least one minute and reinstall. If it doesn't work call their customer support and get put through to tech support.
That did not work. Call to the tech support says that all 0:00 second calls end in response to some type of code (mentioned a specific code but I forget) and that it means my phone is responsible. She said android phones allow for rejecting calls based on various categories like toll free originating and such. And that the phones calls not getting through likely belong to a category I have blocked. She mentions just goto phone menu, settings, and something like call block, call reject and I will most likely find something there. If that doesn't work to do a backup and factory reset. To do that she says I need to call zte for help as she isn't allowed to help with it.
My zte phone interface only shows call barring settings with a few things like all incoming or incoming roaming, outgoing or outgoing roaming and that is it.
However it is possible that I came across via a web search a USSD code to ban telemarketers and used it. I just don't no what code it was or even if I did such a thing.
Anyway I called back their customer service to maybe get further help and had specific phone numbers and times of calls that were rejected by disconnected number messages from my workplace. To see if the problem could be isolated at my phone as a reason or maybe in the network somewhere. And was also wanting to know how I can unset the call reject if I have no interface to do it or undo it. Maybe even get confirmation that the noted calls are actually making it to my phone or getting dropped in the network. The new customer support first asked if it was a ported number and since it was, he checked with someone to see if it was a problem. The porting people said all calls were routed correctly through to my phone, but the customer support guy said there was no way to verify if my specific noted calls were included.
He mentions their tech support did not help with actual phone troubles, but he suggested I get another sim card and phone and use them in varios combinations with my phone and sim to get the working/ not working situations and isolate the problem. This I have not done yet as it seems like a lot of expense and jumping through hoops trying to fix a problem that seems like it should be able to be verified in a phone setting log somehow. He refused to put me through to tech support when I said I wanted him to anyway.
My emails with zte have them requesting I do a backup and factory reset, if that doesn't work then try a new sim card, if that doesn't work then book my phone for a repair with them.
So my question number 1 is:
Is there a USSD code that allows me to see settings or logs of such a call reject being used. I have tried *35**# which is supposed to show "incoming call barring" and it responds "Call barring Service has been disabled." My phone user interface doesn't provide for this as best as I can tell.
My question number 2 is:
What is the USSD code that I might have used to try and reject telemarketers which might issue tones that might indicate a disconnected number. I'm thinking this is the most likely reason for my troubles. I have been unsuccessful google searching for what I may have done. I find info on various USSD codes at this forum and elsewhere. But I'm not finding anything specific to help. I thought the *35**# would have helped but it doesn't. It is very possible I did do something like this with a USSD code which is causing my trouble.
.
Part 2 of this question is what would be the USSD codes to see the status or to unset such a thing.
My question number 3:
If there is no way to set status or see the status of call barring and rejecting logs or settings of the phone. If I do a phone reset, how is it possible that it could be the sim card instead. Does the sim card actually store call rejecting and barring settings as well.
Part of troubleshooting this involves me contacting third parties such as work, doctor, or hospital and asking them to try and call me and if not successful contact me someway else and tell me it was unsuccessful. I really doubt any of them want to do this for me more than once or twice. So I'm trying to gather info and limit my number of attempts. It would be real useful to be able to look up logs or settings somehow.

Would anyone know if the effect of *77 being used is that the caller experiences reaching a disconnected number. Or what do they usually experience.
In web searching possible codes I may have used, I came across the *77 code to reject anonymous callers. The *87 would be to unreject such a setting. Is there a method to check the current setting of either on or off somehow.
I am unable to test the specific phones getting the message of reaching a disconnected number. I will however have better access to one of the phones in three weeks time to see if *87 fixes my troubles.

At&t visual voicemail

I can't get visual voicemail to work on my phone. Talked to tech support and after an hour of trying to help me, they said this device is not supported by AT&T.
I tried setting up Google voice on this phone, but the phone won't let it forward calls. I just get an error.
Any help greatly appreciated.

What was tried for vvm?
Is it enabled in the dialer settings?
Not clear what the problem with GV is.

Try dialing *004*xxx-xxx-xxxx# (substituting your GV# for 'xxx-xxx-xxxx') to get calls forwarding to GV when your phone is busy or unanswered

When I use the *004*xxx-xxx-xxxx# I get "call forwarding connection problem or invalid MMI code. (1)"
When I try call forwarding through the phone app settings, I get "network or sim card error"
Reading online a new sim card won't fix this. I have reset network settings and rebooted. I've call ATT text support, but they have no answers and tell me this is an unsupported device.
So I can't get att visual voicemail to setup and because I can't use call forwarding, I can't use Google voice for their visual voicemail.
Any suggestions?

*004*xxxxxxxxxx*11#
That's the GSM code,works on AT&T and TMO, or at least did on my 3G phones.
Also seen **004*1xxxxxxxxxx# mentioned.
(Note 2 *s and the 1 before number

I tried both and get the same errors as before. You don't realize how much you miss a feature until it's gone. Standard voicemail sucks. Anyone else have a suggestion?

Maybe try 002 instead if 004?
(Though that forwards all calls. Could then deactivate with #21#)
Or the individual conditions using *67, 61, and 62.

They worked with TF AT&T when I last had GSM, in 2015.
Also saw some posts suggesting that AT&T won't allow changes to Cinditional Call Forwarding from the phone now and to call to have them set/change it.

With the March security update, AT&T visual voicemail now works.
