Hey everyone, we are in Bangkok Thailand. On the second day, I went to a local 7-11 shop to get a sim card for travelers. It was very smooth. According to some travelers, the staff may refuse to sell this sim card to you, claiming it's for Thai citizens only. Well, this kind of confusion happens all the time here. Just walk into a 7-11 shop and hopefully, you will get one like I did. If not, move on to the next one. Good luck and enjoy the beautiful Thailand!
What you need: 49 baht and a passport.
What you get: unlimited internet service in Thailand for 7 days.
What to expect: after 3 days of using it, the speed gets to a level where it may take quite long to upload a video or even play a video. Therefore, bear in mind that this sim card tends to slow down dramatically throughout 7 days.
