Can USA tmobile microsim work with japan iPhones 10R?. Have a Japanese student coming here to United States but would like to get setup early to have a US phone while in Japan. Will the SIM or Nano SIM or eSIM work with the Japanese iPhone? We are going to send it to him the Nano SIM. He is a nephew in Tokyo.
 
the XR, and other iPhones use a nano-SIM (and not a Micro-SIM, they are different sizes). If you send him a nano SIM tied to an active plan, it will work on the iPhone XR. Something I would definitely make sure is if the iPhone is unlocked or not as I am not sure how Japanese telecom policies work.

Personally, I run an unlocked US iPhone (purchased through Apple) on T-Mobile out on my trips to Asia with no issues. T-mobile goes into roaming while overseas, but I usually find a local carrier and use their network either via nano-SIM (physical) or eSIM.

I would recommend having your nephew check with his carrier and you inquiring T-mobile just to be sure, but I have had no issues so far. As the nano-SIM isn't tied to one device, another method might be for you to activate a SIM (via your iPhone) then ship it to your nephew.
