Start with compatibility
Confirm eSIM support and carrier-unlocked status before comparing prices. A cheap plan is not useful if the phone cannot install it.
Compare data and validity together
A 5GB plan for seven days is a different product from 5GB for thirty days. Match both the allowance and the validity window to your trip.
Keep the order details accessible
Use an email address you can access while traveling and keep the order number or secure eSIM page available in case you need to reinstall settings or contact support.
