I am currently living in the UK and use my RW SIM from home, on wifi to make calls to the USA, to get voicemail, and to text friends. No problem there.
However, I also have a SIM-only plan with a UK provider for day to day use throughout Europe. Here’s my issue - I cannot make wifi calls on my RW phone with the UK SIM despite wifi calling being included in the plan. It’s like RW had done something to the hardware that blocks this. All 3 RW purchased phones in my household have this problem.
Any help would be appreciated.
