Follow up question... I have decided to bring an old phone as I simply do not like people handling my in use phone. So what is a good prepaid SIM card to buy which I can use over there. If it is also useable here that would be great. I hope to purchase this at 7-11 oif possible. This whole phone thing is quite annoying to say the least.
I plan to add email and a few photos along with some random IM app and that will be it. Any potential issues with that? BTW I am not a millenial. I am foreigner business person. I dont see why they need to harrass people like this.
