I am moving to Japan for one year in two weeks. I am currently in America on AT&T on an unlocked iPhone 15 Pro, and would like to keep my number for when I come back. I plan on using google voice, and understand that you have to port your number to google voice while in the US right before leaving, but I was wondering how I should go about connecting to data once I land in Japan until I get on a Japanese data provider. Would it be best to buy an eSIM online prior to flying to Japan, porting my number to google voice at the airport, and staying on the eSIM until I get on a Japanese data provider? I am mainly worried because I plan on using Apple Maps to get to my hostel once I land.
