Which eSIM should you buy?
For most trips, Airalo. It has the widest country list, the most consistent regional plans, and it is the safest default when your route crosses borders. Saily is usually a little cheaper on a single country. Yesim is the one to pick if you want genuinely unlimited data in one destination rather than a fixed allowance. Drimsim works as a pay-as-you-go backup profile for people who take many short trips or go somewhere obscure.
Entry prices start around $3.49–4.50 for 1 GB on a single country. That is the number to hold against your own carrier's roaming: Verizon TravelPass and AT&T's International Day Pass run roughly $10–12 a day, so one week abroad costs $70–84 before you use any data at all. Without a pass, AT&T's published pay-per-use rate is $2.05 per MB — about $2,099 for a single gigabyte.

Three things that stop an eSIM working
- A locked phone. A handset bought directly from a US carrier and never unlocked may refuse to install a third-party eSIM. Carriers generally must unlock after 60 days of active service, but you have to ask — do it before you fly, not at the airport.
- Your home line still roaming. Verizon's TravelPass is enabled by default on most plans and activates automatically the first time your phone uses data abroad. Install the eSIM, switch cellular data to it, and turn data roaming off on the carrier line, or you pay for both.
- Open sea. An eSIM does not work at sea — there is no land network to reach. On a ship the only options are the vessel's Wi-Fi or cellular-at-sea, and the latter bills as maritime roaming.
