After arriving to Thailand buy local SIM-card and ask a seller to insert and activate it. In the Suvarnabhumi Airport (Bangkok) shops selling SIM-cards are near the exit. Put some money on the account. Attention! You can buy SIM-card if you show your passport only.
If you want to have connection with Internet anywhere фтв constantly ask seller talk about internet packages he has. At once pay for the internet package and ask the seller to activate it. At once check your mobile and internet connection. If you have any questions ask seller (at the airport they speak English usually).
You can do it yourself through your account in your mobile network site.
There are two main telecom operators in Thailand:
- DTAC – official website DTAC company. DTAC tariff plans.
- TRUE – official website TRUE company. TRUE tariff plans.
Both operators cover the entire area of Thailand. Coverage area and communication quality are about tequal but sometimes I think that the DTAC is better.
