Is using my UK or US SIM card for data in Thailand free, or will I face roaming charges?

Unfortunately, no, using your standard UK or US SIM card in Thailand will almost certainly incur significant roaming charges. Unlike the EU where roaming is often included, Southeast Asian countries like Thailand are typically outside these agreements. EastESIM helps you avoid bill shock by providing a local data connection at a transparent, upfront cost. Imagine exploring the vibrant markets of Bangkok or the serene beaches of Phuket without worrying about exorbitant fees for sharing your adventures!
