Evening All,
I bought a couple of iPhone 12 mini's (on the latest iOS) and put prepaid TMo SIM cards in them to test them out. I know that TMo prepaid does not offer International roaming. I also know from past experience that an iPhone without a[n] [e]SIM will not allow you to use the Messages app using Wi-Fi only, unless something has changed.
What I am curious about is if I leave the prepaid TMo SIM in the iPhone, turn off Cellular data and use Japanese eSIM once abroad (Ubigi in Japan) will I be able to use Apple Messages if I also turn off 'Use SMS if Wi-Fi is not available' feature. If not them I will seek out a pure data-only communications solution that will allow me to use voice/video communications with family back home.
I do know that there are some in-Japan solutions that would allow me to receive incoming voice and text at no additional charge, but outgoing would be a per use charge that I am looking to avoid. Those are SIM-based, of course.
