Wifi calling not working on unlocked lg stylo 4
Hello, I recently migrated my unlocked LG stylo 4 from Xfinity Mobile to T-Mobile prepaid. Things are mostly working, calling, voicemail, text messages. But I cannot get wifi calling to work again. It worked before with xfinity mobile. I tried a lot of things. I installed all updates for my phone, updated my e911 address on the t mobile website, tried various Wi-Fi networks, restarted my phone, remove reinsert sim card. When i try to enable wifi calling, it says "this may take a few moments", then after a minute or so it says: Unable to activate at this time, please try again later. Any help would be appreciated, thank you.
