FAQs
Which SEA country has the weakest coverage?
Eastern Indonesia and the Philippine islands are the thinnest — ferries and remote beaches go dark on every brand. Thailand, Vietnam, Malaysia and Singapore are uniformly strong on quality plans.
Is Laos/Cambodia included in SEA bundles?
Often yes on larger bundles, sometimes as a smaller subset. If your overland route includes them, tick them off the plan's country list before buying.
