I’m using the iPhone 16 and I have had multiple people tell me that I break up constantly on the phone. I tend to get 1--2 bars only, when checking the coverage checker it says I should get “excellent” coverage and 4 bars. If I go outside into the street, I will get 3 bars, but inside is never above 2. I never had any problems on my previous provider.

I’ve also enabled Wi-Fi Calling, but that only seems to activate if I turn on aeroplane mode, is that correct behaviour? And is there a way I can just force that on? 

I’m just very disappointed right now, being able to make clear phone calls is about the bar minimum I expect. I have restarted my phone and router, updated to the latest version of iOS, turned aeroplane mode on for a minute and turned it off and nothing seems to improve the signal. I’ve looked into “mobile boosters” but I don’t know how well they work, if at all.
