Is roaming free in Thailand with my UK or US SIM card?

It's important to clarify that 'Roam Like at Home' policies typically apply only within specific regions like the EU, and Thailand is not part of such an agreement. Therefore, if you're using a SIM card from the UK or US, you will almost certainly incur significant roaming charges. Most UK carriers (like EE or Three) have reintroduced daily roaming fees, while US carriers (such as Verizon or AT&T) offer international plans that can still be quite costly. EastESIM provides a transparent and affordable alternative, connecting you directly to reliable Thai networks like AIS or TrueMove H, letting you enjoy your trip without bill surprises.
