Yes, absolutely! This is a common pitfall for travelers. Thailand is an independent country and is not included in typical domestic plans from the US (like AT&T, T-Mobile), UK (Vodafone, EE), or Canada. Using your home SIM will almost certainly lead to exorbitant international roaming fees, often costing $10-$15 per day for a minimal data allowance. EastESIM offers a cost-effective alternative, providing local rates and reliable connectivity across Thailand, saving you from bill shock while exploring Bangkok or Chiang Mai.
