Hi, I'm looking for more information about Thai 3G sim card and prepaid plans. The idea is to get a prepaid 3G sim card that I can top-up during my stay in Thailand hopefully easily along the way. - Can anyone please recommend a few to me please ? - How is the coverage ? Should I expect to loose reception if I'm too far away from bigger cities ? - Where can I find top-up options , do gas stations or hotel/guesthouses sell them ? The idea is to use the 3G data to provide an internet connection either by using the iPhone (unlocked) and turning it into a wifi spot, or by putting the sim card in an USB modem and plug it to the laptop during the trip. I hope this is the right place to post this, I picked the first Thailand regional sub forums not knowing where to post, and also because I'll be entering Thailand from the South so that's where I'll be looking to purchase the sim card.
