Can I expect free roaming in Southeast Asia with my home SIM card?

For most travelers, especially those from outside Asia, relying on your home SIM for "free roaming" in Southeast Asia is usually not an option. Unlike some regional agreements, there isn't a widespread "Roam Like at Home" policy across countries like Vietnam, Indonesia, or Malaysia for international visitors. Your domestic carrier (e.g., from the US, UK, Australia) will almost certainly charge expensive daily roaming rates, often $10-$15 per day, which quickly adds up. EastESIM offers a far more cost-effective and predictable way to stay connected, specifically tailored for your Asian adventures.
