Cool, so that takes the SIM and operating system out of the equation.
What happens if you swap your SIMs over? (The only impact in this is that you may have to change the phone numbers bound to the devices afterwards, should be automatic, but the key areas where the phione number matter are in iMessage, FaceTime and the 'My number' under Phone).
[Edit] Also, did you do a sim swap when you got your phone?

I found this issue when the SIM became unbound just before going on holiday in May. There are a number of systems that need to recognise the new SIM.
The way that mobile networks work is that the UICC (SIM card to you) has to be told it has your number on the systems (voice and data). I was able to connect to data but not calls in my issue. This is obviously a different issue to what you are experiencing, but it is a glitch that wouldn't be apparent in normal use, has it ever worked roaming?
Swapping the SIMs between your phones would rule out the phone or the SIM (if you're SIM works in your husband's phone then it's the phone, and vice versa).

OK, when did you first notice the problem (only asking is that you say it happened since they lifted the charges, does that mean you've noticed the problem on the first time you've gone abroad since then or it was working before and stopped working when the cap was removed)?
