I've been having an issue for about a week now where as soon as my phone connects to Wifi, I begin having issues sending and receiving text messages. I've been having the same issue as well as my Girlfriend, her Mom, and her Daughter all having the exact same issues when on WiFi. This includes 4 different phones, 3 different Samsung models and an iPhone. All T-Mobile devices. This issue seems to only be with text messaging. No issues with calls or any type of Data or internet related App. Just sending and receiving text messages.
I called support last week because I was certain this was a known issue for many people, but was told it was not. I went through all the trouble shooting steps with the team and nothing they could do seemed to fix the issue. I cleared my cache, checked my data to ensure it was all setup correctly, I'm even now using a brand new Note 9 and still having the same issues. When I called originally I was using my s7 Edge.
I've taken a few photos where you can see the change.
When you're not on WiFi you can see the 4gLTE symbol next to the service indicator and it seems to work fine.
On top of the issue with sending failures, sometimes after taking minutes to send, the person who is receiving the message will get up to 4 copies of the same message. I will also receive up to 4 copies of a message when getting texts. So it's an issue with incoming and outgoing.
This seems to be something that change with an update/service. Not the device or anything. When I got my note 9, the 1st thing it had me do was connect to WiFi and I immediately noticed this same issue (no 4gLTE symbol) before installing a single APP or anything.
I'd like to point out, this is not always an issue. Most time it works pretty well, however it's a daily occurrence for the last week. Happens while I have full cell and 500MB+ WiFi service.
If the messages are only failing when the phone is using the Wi-Fi calling, this is going to be something that we will need to open an engineering support ticket for. Please gather a few examples/date/time/numbers of the failures and contact us so our tech care folks can get a ticket opened up for you.
if this is happening on all phones on all Wi-Fi networks then it would have to be an account issue. I did not see where all phones were on the same account however T-Mobile we need to address of the line settings and make sure that everything is refreshed and that there is no specific block or other issue on the account level.
"cellular preferred" was at least as bad or worse - no texts were getting through while I was on a wifi network. Today I had wifi calling turned off, though, and texts are getting through promptly. So it's definitely a bad interaction between wifi calling and texting - any suggestions how to fix?
One of my work locations is in a building with solid wifi but poor cell service, so it's important for me to be able to enable wifi calling when I'm there - and still receive texts!
I have been having issues for a while. I just assumed it was my phone. (not a normal one) interesting to see its not just me. Phone calls and texts both only seem to really come in when I am not on wifi. In order to sign in, I had to take wifi off to get my two-factor authentication to get the text. I can call out no problem, texting out sometimes does not seem to be an issue. It's also not EVERY text. it's strange.
My partner and I ported our phones from Verizon in November. We both purchased new devices when we ported over- iPhone for me, android for him. We never had any issues with our old service and our old phones. Since porting, neither one of us has consistently received text messages. We’ve called and had trouble tickets opened and no one has called us back. The only troubleshooting attempted was to just never have WiFi on on our phones (seriously?). T-Mobile, we’ve been your customers for 6 weeks- your service problems have apparently been going on for years and your support is nonexistent!
