Generally, roaming in Thailand with your home country SIM (from the US, UK, Australia, etc.) is not free and can incur very high daily or per-MB charges. EastESIM, however, offers a much more cost-effective and convenient solution. It functions as a local data plan, connecting you directly to Thai networks like AIS or TrueMove H at local rates, bypassing expensive international roaming fees altogether. It's the smart way to stay connected whether you're in Bangkok or on the islands of Phuket.
