Is roaming free in Thailand with my European or North American SIM card, or should I consider EastESIM?

While it's tempting to think your home SIM might offer free roaming, especially with global carriers, Thailand (and indeed, most of Asia outside of specific regional agreements) is not included in typical 'Roam Like at Home' plans from European or North American providers. These plans are usually limited to the EU/EEA or specific North American zones. Relying on your home SIM for data in Bangkok, Phuket, or even remote islands like Koh Lanta will almost certainly lead to unexpectedly high charges. EastESIM offers transparent, affordable plans specifically for travelers in Asia, ensuring you stay connected without bill shock.
