The Booking.com-branded eSIM storefront is powered by Breeze. Its page states that Breeze alone provides the service and Booking.com is not responsible for it. Check the seller and support terms separately from your hotel reservation; an accommodation booking does not by itself prove you have bought mobile data.

What the official information says
If you already purchased through the Breeze storefront, use that order’s support channel for installation or refunds. Buying a second eSIM from another seller will not repair the first order. Compare independent alternatives only when you still need a plan or your existing plan does not cover the journey.

Compare the plan you will actually use
Compare like for like: countries and supported networks; total versus daily data; the period when validity starts; hotspot permission; any reduced-speed limit; the final checkout currency and refund terms. A lower headline price can buy a different allowance. Check whether your home mobile plan already includes sufficient roaming before paying twice.
Prepare arrival before leaving Wi-Fi
Check your exact phone model and carrier-unlock status. Install using reliable Wi-Fi and the selected plan’s instructions. Download maps and essential booking details beforehand. At arrival, select the intended line for data and follow its roaming settings. Keep your home carrier’s call and SMS charges in mind; switching off home data roaming does not necessarily stop those charges.

Choose by destination
The accommodation or flight platform does not determine mobile coverage. Choose the countries on your itinerary, then compare the current destination plans below. esim0 plans are data-only: no local phone number, ordinary calls or SMS. Apps need a working connection and local availability. Verify the live plan details and refund conditions before payment.
Frequently asked questions
Is mobile data included with my booking?
Only rely on what your reservation and actual offer explicitly include. A separately advertised data plan is not automatically part of the booking.
Do I need an eSIM if Wi-Fi is included?
Not always. Wi-Fi or your existing roaming allowance may be enough; an eSIM is useful away from Wi-Fi where its supported network has coverage.
Can a data eSIM receive verification SMS?
esim0 data-only plans do not include SMS. Arrange access to your account’s verification method before departure.
Is esim0 the official platform eSIM?
No. This guide and an esim0 purchase are independent of your accommodation or flight booking.
