WIFI Calling Preferences Being Forced to Cellular Preferred

I set my Galaxy S9 to airplane mode, then turned on Wi-Fi and Wi-Fi calling last night. It should never switch to cellular and always be active on the internet. This afternoon, I called my cell from my home phone and got the message 'This phone is not accepting calls, try again later'. Five minutes later I tried again and my phone rang almost immediately. Five minutes later I tried again and after about 30 seconds I was sent to my voicemail. This has to be a phone and T-Mobile Wi-Fi calling network issue.

There is no workaround for this problem, and T-Mobile and Samsung seem unable to fix it. If you need to use Wi-Fi calling when you have poor cellular service, expect to miss a lot of calls.

The only fix on T-Mobile is to switch from a Samsung phone to another cellular phone company product. This probably means a phone upgrade at regular price to fix a problem caused by T-Mobile and Samsung. 

If you like Samsung phones, like I do, the solution is to switch to another cellular provider. I have Spectrum Mobile in my area and their price for a senior citizen not using much high speed data is much cheaper than my T-Mobile plan. The problem is it uses the Verizon network and my S9 is not supported. I will have to get a new phone, but even then if I use less than 1 Gig per month the Spectrum plan cost will still be less than my current T-Mobile plan, even paying for a new phone.

The secondary issue I have is with customer support. My problem was forwarded to Technical Support and I was told to expect a callback. A week later, after no callback, I called in again and eventually was connected to Technical Support. They had me try a few things, but nothing corrected the problem.

I am in contact (I thought) with corporate customer support, but after first contact they seem to be ignoring me as well.

I get the feeling they want customers with problems they can’t fix to go away.

They will soon get their wish.
