What are Your Options When Choosing Phone Providers in Thailand

Thailand has three major mobile phone network providers and two other minor cell phone operators. You can use any of these three networks to get cell phone coverage, all you need is to purchase a local SIM card and purchase some airtime. On the other hand, if your stay in Thailand is more permanent, you can get into a plan that allows you to make monthly payments. Additionally, if you register your cell phone number during the purchase, you can get the number replaced when you lose your SIM card.


Otherwise, you would have to get a new number every time you lose the number you already have.
