[Q] T-mobile One S won't receive calls

Hey everyone, I just got my One S yesterday and found out last night that the incoming phone calls aren't coming through. I can receive and send text message and make outgoing calls. Any idea if this is a problem with the phone or maybe a t-mobile outage?

Why don't you call the store you got it from or call C.S you just got it so anything wrong with it could be handled with them. Have you tested it yourself calling from another phone?

I just realized that wifi calling works. I also just called t-Mobile and after 30 minutes of diagnostics they told me that there is a network outage for new activations. Since it took them so long to figure out there is a network outage, I think they are full of it.

Are you still having this issue?
My wife just emailed me saying she was trying to call me but the call wasn't going through.
I was immediately getting calls when I changed my SIM yesterday...

When I first turned the phone on and called to activate my new SIM, tmobile made a test phone call to my new phone and everything worked fine. But now that I think about it, I think wi-fi calling was active at the time. I haven't received any calls today so not sure if the issue is still there.

This happened to me when switching telco, I got a SMS from new operator with a date but no time when my number would be ported. On that day I could make calls and send SMS but not get any calls. Turns out my number had been ported to new telco without me realizing this (I was still using my old SIM since it seemed to work to me.) After changing to new SIM everything was fine. All of this was on a desire though so might not apply to you ofc

Sounds like you have a bad phone, call CS or take it back and demand a replacement.

Calls not coming through - possible solution
I had this problem when I first got it.
First under settings->call->Use Internet calling - make sure you select Only for Internet calls.
Now go to wifi and make sure you are connected to a Wi-Fi network - then click the More menu listed under Mobil Network (three dots). If you have wifi calling enabled, go to Wi-Fi Calling Settings->Connection Preferences and select Cellular Preferred - otherwise you won't be able to make calls when not near a Wi-Fi.
Hope this helps - it took me forever to track it down!

The problem is i can make calls, just can't receive them. I don't think it's the phone as when people call me it goes to an automated message saying i'm not on the network. Even my voicemail doesn't work.

Wifi/Wifi Calling/Airplane mode/MMS weirdness

Ok. This is very strange. It's happening on both of my One S phones. It's possible it only started after the OTA update.
When wifi is on and wifi calling is enabled, the airplane mode setting goes into a state where it says it's "turning off" and the on/off button is diabled.
When it's like that, I can not send MMS with Go SMS (I can send with stock messenger during that time).
If I turn wifi calling off, airplane mode goes into off and I can send MMS with Go SMS.
I know the OTA had something to do with a wifi calling fix, but I think they broke something.
It's like when wifi calling is on, it's disabling the ability for mobile data to come on to perform functions that are not done over wifi (i.e. MMS).

How do u activate WiFi calling? Sorry I'm not stealing your thread and is it true if using WiFi calling u don't use your minutes?

It's in the settings menu, I don't have the phone at the moment, but I think you have to click the dotted line under mobile network and it's in there. Yes, wifi calling is free, but you have to call them and add a free wifi calling plan to your account.
Any further discussion, I'd ask that you start your own thread.
Anyone able to confirm my findings on the issue I posted about and any thoughts as to what's going on?

I cannot exactly verify what you are experiencing, but I use GoSMS and I have always had trouble with it and wifi. But I do think it had gotten worse since the update.
In my situation when I boot the phone art home (where I have no signal and a fixed, auto wifi connection), wifi calling isn't on... Until I make a call. Then it takes about a minute to turn on and turn blue (it almost always starts out with an "invalid SIM" error). And in my situation, until wifi calling is running, my SMS is spotty. Them while it is initially on I can also send SMS. Then when it goes off again (usually if I don't make a call for about 30), at this point I cannot send SMS without a reboot.
I am running various log applications, and in reading the log enough times, I can definitely see consistent regular errors mentioning the GoSMS app. I also am pretty sure this update fixed a few things, but it also broke stole things.
You should go download a log program, and let me know of you see GoSMS errors.

That's for comfirming!
How'd the screw this up so badly? It's going to be months before they push a new firmware up to fix this.

Same here

So any work arounds to get MMS to work with Go SMS w/o turning off wifi calling?
Also, I posted on the T-Mobile forums here:
http://support.t-mobile.com/message/148722
Maybe some of you can jump in here and voice your complaints too?

I was able to get HTC to escalate to a tier 2 tech who was very vigilant with trying to reach me to discuss the issue.
After detailing exactly what's happening, he commented that he say some other reports of this issue and something about a youtube video detailing it as well. Said he'd look into it further.
The next day, he called back saying they confirmed it's a bug and it would be fixed in the next maintenance release, but had no idea when that would be.
Very happy with HTC's level of support (after the first few go arounds getting tier 1 to finally understand what I was talking about and escalate).
A T-Mobile forum rep also noted that they've reported the problem and are working on it as well.
Not much else I can do here. Hopefully there will be another software update coming in the next month or 2.

This is happening to me as well. Like you all, when I called Tmobile to ask them about it, they said both the signal fluctuating problem and the random airplane mode are known problems that HTC "is working on a fix for. I guess the pro is that this has been a pretty big phone for both HTC and Tmobile, right? So I'll be optimistic about a fix. OTOH, can I assume this isn't a problem in the ROMs?

Well I hate to disappoint, but this isn't just a HTC problem, I am on the Galaxy SIII and I am experiencing the exact same issue. I'm not sure if T-Mobile uses their own programmers to code the wifi calling and functions, and then just submits it to the manufacturer to add in or what, but there is definitely an issue here.

Maybe that's not a bad thing then. Perhaps an update to the wifi calling app is all that's needed to fix? That certainly would be a lot easier than needing new firmware.
Are you having the exact same issue?

Here is a quote off some research I've done:
It could be done technically. AFAIK all communication between MMS enabled components is done via standard TCP/IP. But in a regular provider setup the MMS store and forward server(s) (MMSC) are only reachable via the providers network. That's why you can not send and receive MMS via WiFi.
It's also the reason why you can not make a call and send/receive an MMS simultaneously when you have only 2G (GPRS/EDGE) connectivity.
Normally android will drop the GSM data connection if there is WiFi connectivity and all data will be routed through the WiFi interface, but there is one exception: The MMS traffic will still go through the mobile data connection.

So normally, if you are connected to WIFI and send an MMS, it triggers your phone to open up the data connection with your carrier just long enough to send your MMS. With TMobile, there is something in the programming that is stopping our phones from doing so. However, this seems more of a GoSMS issue now because the stock messaging apps does perform this function fine.

I'm seeing this problem as well, but the other issue with WiFi calling for me is that it doesn't do touch tone automated systems well at all. Such as voicemail. It straight up doesn't recognise my password input at all unless WiFi calling is off.

I owned the ONE S before the SIII and had the same issue -- It will record your password, you just need to type it a lot slower than normal. I would suggest setting up visual voicemail, or downloading a visual voicemail app like Youmail.

Call ended right away? Can't make calls

Hello,
I was wondering if anyone is experiencing this weird hang up. When I try to make calls, it automatically ends my call without any rings. I keep trying to call and it keeps ending right after it dials.
I had to restart my phone to finally get it to work. It has happened twice to me now.

Same exact issue here. Rebooting sometimes works, sometimes doesn't. Tried uninstalling Google Voice, same issue. Annoying as heck.

Same issue here, on T-Mobile. I exchanged my original phone because I was having radio issues (phone would not connect to the mobile network), but this problem seems to have carried over. Phone is set to use WiFi calling, I'm wondering if there is a handover issue when I leave my home wireless network.

I'm on T-Mobile as well, in north Dallas area. I do not have mine set to do WiFi calling, as it is guaranteed to drop your call when you leave your house (happens every time to me, so now I don't bother with WiFi calling).
This instant "Call Ended" issue is separate.

Yup, happened to me earlier, i had to turn the phone off for 15 minutes. Im on t-mobile

Solution!
I believe I have figured out how to fix this. Go into Settings, then More..., then make sure Wi-Fi Calling is on, then click on Wi-Fi Calling then make sure you have Cellular preferred selected. After I did this, I was able to make calls with Wi-Fi on or off. Hope this fixes yours too.

Same issue here. Call hangs up right after i hit dial. Tonight even resetting the phone twice didn't solve. Finally after 20 minutes I was able to make a call. So frustrating as I had an important conference call I needed to be on. I ended up texting a few people in the call, and my texts were successfully received, just couldn't call out. So frustrating, but comforting knowing that I am not alone. Think I might return this phone as this is the 5th time this issue has occurred and I've only had the phone for 6 days.

Sorry, that is not a fix. I've used that configuration and still ran into the instant call ended problem. Thanks for the suggestion though.

VoLTE (voice over LTE) could actually be the problem - that is a setting that comes pre-enabled and I never disabled it. Makes sense to try disabling it and see if it happens again.
I'll report back in a couple days whether the issue happens again with VoLTE disabled.

Man I really like this phone, but the call ending and camera issue, I had to return it. Damn you sony!

The call ended issue hasn't happened to me since disabling VoLTE. Though I did get a call from my wife when she got off work, which when I swiped to answer, my phone rebooted.. that was fun.

It only happened to me once. Rebooting had no effect, but after turning off LTE everything worked. Makes sense that it would be a VoLTE issue.

you can try fiddling with the network mode settings in the more wireless/network option. the t-mobile rep. got it working again after switching the network preferences from LTE Preferred to GSM. That got calls working again. I believe I switched it back to LTE afterwards and I'm not experiencing any more problems with that error.

Same here. It was totally random as to when and how long it would automatically end calls.
VoLTE settings made no difference. Eventually the problem would return.
I just replaced it at the TMobile store.

Problem Solved!
So, I was having this same problem and reading this forum, I discover that I just need to change the network mode
Go to settings > More... > Mobile Networks > Network Mode
And it probably its marked LTE (only).. Just change it for LTE(preferred)/WCDMA/GSM
I hope it can help you

I have HTC One M7 with cm12.1 and I'm having this issue too!

Text Messages not coming in

Hope someone can help me with this. So I got my phone yesterday and I set it all up and everything and I realised that I had bars but not data, no texting, or calling. So I did some research and remembered that I probably needed to change the APN, the default APN was set to Verizon and I have Xfinity Mobile so that made sense but it didn't work so I set it to Xfinity Mobiles APN and data works now I can call, receive calls, and even text others and they'll receive my texts. But for some reason I am unable to get any texts from anyone, no MMS or SMS. I'm really not sure what I'm missing, I don't want to have to go through my carrier and deal with their crap so any help is appreciated.

zandander is right, but more specifically; It looks like either time will resolve as they add the device through natural attrition, (24-48 Hrs) or contact them (877-894-4946) and request feature # 83856 "CDMA_LESS"

My understanding from talking to Xfinity mobile service people is that they have no power to change the device to CDMA-less (one of the reasons they only support iPhones for byod). This was about a year ago, but they still haven't added any Android byod support so I don't things have changed.
Verizon is phasing out CDMA all together so it might not be a problem for much longer: https://www.verizonwireless.com/support/knowledge-base-218813/

Do they make you change your plan if you are on a legacy unlimited data plan to go CDMA-less?

No Incoming SMS or MMS on Verizon

Hey OnePlus fam,
I just thought I would put this out as PSA for anyone on Verizon and having issues with SMS or MMS, as there is little information out there on this for our specific phones.
If you are unable to send or receive any text messages it is most like that the "CDMA-Less" feature needs to be activated.
You can call Verizon and ask them to enable "CDMA-Less" to your account.
Hope this helps

I had to get a new sim card that fixed my problem

Here are also a few links too; the first two are for a 6T but to concept still applies.

VZW information
https://opendevelopment.verizonwireless.com/faqs?s=LTE

Had the same issue.
Called Verizon and asked them to enable this device as CDMA-less.
Been working perfect since.

Same here. I inserted my Verizon sim in the international version. Data at 50Mbps, Voice, Visual Voicemail and outgoing text messages worked. If it doesn't work for you, make sure you are using slot 1. It may matter. If you have a very old sim, you might need a new one.
I called Verizon and carefully explained that incoming sms was not functional as this was a next generation phone for a world where Verizon turns off their CDMA at the end of 2019 and SMS is routed over LTE. I instructed him to make sure "CDMA-less" was available both in the billing account and the network account. After a bit of digging he found the provisioning settings. Seconds after the phone was provisioned, sms started flooding in the stock message app. Also make sure IMS Basic Visual Voicemail is on your account if VM is giving you trouble. I use VZW Message+ (Verizon Messages) for sms as I can text from a PC also and it will restore previous sms.
By definition the phone uses VOLTE so there is no setting for HD Voice in the phone. That feature is required on your Verizon account but you would have to be switching from an ancient phone not to already have that. I cannot locate any option for Wifi calling and it does not work in airplane mode. I have a google voice number which allows Wifi calling. Interestingly it errors when the phone is in airplane mode but works when cell service is on. It reports "Wifi Call" and appears to use the stock dialer when initiated from the Voice app. Somehow Voice is even more tightly integrated with the stock dialer now than just trapping and routing international calls. This is a bug of sorts as my Moto phone on 8.0 could call in airplane mode with wifi on.
Google Duo appears to be integrated in the dialer but I haven't tried with my wife's Pixel to see if I can switch to Duo while on a regular voice call.
Bootloader unlock was simple: Tap Build # 6x, Developer Options - OEM unlocking, adb reboot recovery, fastboot oem unlock [This erases the phone]
The 7 Pro is an amazing device! Truly the most amazing. I'm really excited. The phone is super super slippery and a drop magnet. It does come with a TPU case.
I'm going to sell my kid's mint 5T and upgrade him too!
BT sucks worse than the Moto phone but I think that is an Android thing as my wife's pixel as issues to with her car. Contacts not syncing and calls not going through while connected to BT. Just have to do work arounds when I have some time.
Hoping video is fixed for the wide camera. They are amazing; but then, I'm coming from a Moto phone which has the worst cameras. Sony knows what they are doing.

Sorry to wake an old thread but did not want to start a new one.
I have verizon and have cdma-less provisioning done already. Have HD voice on the account as well. SMS works fine but I can only send MMS not receive them.
Ive tried moving sim card to other slot, tried reboot, tried factory reset, tried different apps...nothing.
The only time MMS fully works is when I am in safe mode. Anyone have any ideas on what it could be?
Thank you

Try looking in permissions at what app has permissions.

Permissions were all good, sms/mms permission is in one.
I tried verizon app, MMS works, dont really like the app though, and the customization didnt help me like it enough to keep it.
Super weird that verizon messages work but not the stock app or the Mood SMS app.

I had to call Verizon 2 or 3 times for them to get it right

I downloaded a couple other SMS apps and they all work fine. So leads me to believe its just something weird with the stock app and with Mood SMS. I will switch to QKSMS for now and requested assistance from Mood SMS so they could take a look. Thanks all.

I'm going to guess MMS didn't work with that app while you were on wifi? Some apps don't know how to route MMS data properly when there both data and wifi available.

It's an option that has to be enabled on the account for Verizon customers, it's the cdma-less option. It took me a couple representatives til one of knew what I was talking about lol

I think his issue is slightly different as he can recieve sms but not mms and it varies on the app he's using.

No that I already checked. I still have not figured out why I cannot receive MMS on the stock app or on mood SMS. Mood had not replied to my email. I switched to qksms and have no issues anymore.
So ya if anyone else runs into something like I did, try different SMS apps

Yup, I learned this very quickly when I got the OnePlus 6t. Just getting them to understand that the phone was certified on VZW. Then 4 techs before one knew what to do. I think they now can address quickly even over chat.

If I get Verizon prepaid will they be able to do this? I had Verizon prepaid once in the past and customer service was much worse than regular Verizon wireless. I am pretty sure that mvnos can't do it but I'm hoping Verizon prepaid can.

I'm not sure

Yeah, there's a lot more to this than enabling CDMA-less. Before about a month ago data/sms/MMS wasn't working on Android 10 based custom roms and MMS still doesn't work unless you use Messages+.

I get both fine I just have issues with them being received after the phone goes idle for a while. My issues are small stupid crap mile messenger not closing with home button all the time and and Gboard sometimes won't type into the field I'm in
