I am visiting Japan for 2 weeks and want to get a local pay as you go SIM card for voice and data calls. I know only Reaidents can buy SIM cards so I plan to ask a person I know there to get me one.
Before I asked I wanted to know if that kind of product is standard as in the Uk. I cheap no commitment sim you can use and discard / keep / use again a few year’s later?
Doing a google search naturally directs me to info for new arrivals / tourists and sim hire options. Hoping I can go local and get something a bit cheaper.
Thanks for any help
