Can I use my European or Australian SIM card in Singapore without roaming charges?

It's crucial to understand roaming policies when traveling to Asia. While some international carriers offer roaming packages, they are rarely 'free' or as cost-effective as a dedicated EastESIM. Singapore, for example, is not part of any 'Roam Like at Home' zone for European or Australian providers. Using your home SIM in countries like Japan, South Korea, or Thailand without a specific international roaming add-on will almost certainly incur significant pay-per-use charges. An EastESIM plan, designed specifically for Asian travel, offers predictable and affordable data, avoiding bill shock when you return home.
