I have gone through 3 phones in just as many months. The first touch screen didnt work straight out of the box and was exchanged in the store. The next phone's battery overheated and caused the phone to crash. Hopefully the 3rd phone lasts.
Wifi calling is pointless. The delay is long, it crackles. I can not have a business call using this.
Service is spotty.
All three phone have randomly decided not to send texts. The message just 'waiting to send.'
Hi @AngryUser, that's a lot to go through and I'm sorry that you have had this experience. There are definitely some troubleshooting steps which you can try on your One S, which may help.
The first step I suggest is a simple soft reset. Go to Settings > Power > un-check 'Fast boot' and press the Home key. Press and hold the Power button until the three soft keys below the screen flash and you see a notification which says, "To restart your phone, continue to press and hold the Power button..." and keep holding until the phone restarts.
You may find that changing your Wi-Fi settings helps with Wi-Fi calling quality; go to Settings > Wi-Fi > Menu > Advanced, and check 'Best Wi-Fi performance.' This does use a little more battery power, but allows for a stronger and more stable connection. If you're still having trouble, try connecting to a different Wi-Fi network and see if the delays and crackling continue.
Sometimes a corruption in a cached text message or attachment can cause issues sending or receiving texts. To clear the cache from the Messages app, go to Settings > Apps > All > Messages > Clear cache > OK. You may choose 'Clear data' from this screen as well; remember that doing so will revert all the app settings back to default and may delete messages from your inbox.
If you still experience these issues, put the phone into Safe Mode. Safe Mode temporarily disables all third-party applications from starting up, and will allow you to determine whether a wayward app is the cause. To do this, restart the phone; as soon as it turns on, press and hold the Volume Down button, and keep holding until you see "Safe Mode" in the bottom corner. If you are able to send a message and make a successful call over Wi-Fi, I suggest you uninstall all third-party applications and re-install them one at a time, taking time between each to watch for performance issues. To exit Safe Mode, simply restart the phone as normal.
As both T-Mobile Wi-Fi Calling and text messaging require a SIM card, it could be beneficial to check that there is no dust, debris or scratches on the surface of the chip. This is especially likely if the same SIM has been used in multiple phones. If you notice any damage, or if was used in an previous phone, you may find that having T-Mobile activate a new SIM solves both these issues.
