using your home carrier abroad
What is international roaming?
A service offered by mobile carriers that lets your home phone number work in foreign countries, by routing through partner networks. Typically costs $10–25 per gigabyte for non-EU travelers.
In context
Roaming is the most expensive way to use data abroad. An eSIM from a dedicated provider like travel.to typically costs an order of magnitude less per gigabyte — without surprising bills at the end of the month.
