It is highly unlikely that your domestic SIM from the US, UK, or EU will provide free international roaming in most non-EU/non-North American countries. While some carriers like Verizon, AT&T, or Vodafone UK offer international packages, these are typically expensive add-ons or limited to specific regions. Beyond these zones, you'll likely incur prohibitive pay-as-you-go roaming charges. WestESIM offers a far more predictable and cost-effective solution for premium international connectivity, avoiding unexpected bills upon your return.
