iPhone 13 Pro Max WiFi Calling Not always On

[Bost85]

Dear Group,

Apologies in advance if this topic has already been analyzed before, though I wasn't able to find it anywhere.
I don't think this is a problem, nevertheless, i wanted your opinion.
Reception in our apartment is truly poor, either 1 line or max 2 in some rooms. Wifi calling works without any toggling on-off-airplane mode and immediately when i enter from outside in our house.
However, i ve realized that whenever the signal stays on 2 bars, and the phone stays in that room for a long time without touching it, wifi calling goes away. The moment i take the phone in another room with 1 reception carrier line, immediately the wifi calling returns back.
Why is this happening and doesn't stay ON all the time?
Is it because the phone realizes that the signal's strength is enough to perform a phone for example?
With an iphone 12 i don't think i saw this before, however, the signal reception of 13 pro max is a bit stronger compared to the 12 (under the same carrier of course, connected to exactly the same router)

Thank you so much in advance for your answer

I think the threshold at which at least my iphone 14 switches to WiFi calling is way too low. I can have only 1 bar with spotty reception and it still refuses to change to WiFi calling, either on T-Mobile, Verizon, or AT&T. It is definitely on in the settings and all 3 systems list it in the respective cell settings but it never seems to work. Ever. Unless they've taken away the indication that it actually IS working and I don't know it (?)

You gonna have to switch to Verizon to get reception in your apartment that way you won’t need Wifi calling

It's mostly carrier related. I have had a carrier before who would activate wifi calling almost instantly when i was connected to wifi. The carrier i use now switches to wifi calling earliest when there is one or two bars.

The only workaround is to go into airplane mode and reactivating only the wifi. Then you got wifi calling (sms works too) all the time.
