Will my existing European (EU), UK, or Australian SIM card offer free roaming in Thailand?

Unfortunately, no, this is a common misconception for travelers heading to Asia. While Thailand is a hugely popular destination, it is not part of the EU, nor is it covered by most standard 'Roam Like at Home' policies from European or Australian carriers. Using your home SIM card in Thailand, Vietnam, or Indonesia will almost certainly incur expensive daily roaming charges or exorbitant pay-as-you-go rates. EastESIM provides a cost-effective and transparent alternative, ensuring you stay connected without bill shock.
