Suvarnabhumi Airport

At the arrival hall, you will be able to buy pre-paid mobile SIM card for travellers from all major mobile operators in Thailand. All the mobile operators were offering the same price of ฿299 for a 7-days data plan (inclusive of 1.5gb of data usage before data throttling). We chose to go with ALS as it was the first store that we came across. The staff at the counter will not only help you install the prepaid SIM card, but they will also help you to activate them to ensure that you will have access to your cellular data the moment you leave the counter.
