US carriers
How each carrier hands out an eSIM, how you activate it or move it to a new phone, which carriers run a free trial on eSIM, and what using your plan abroad costs next to a prepaid travel eSIM.
Written from each carrier's own support and plan pages, checked Oct 2026. We are not affiliated with any carrier.
Most phones that take an eSIM can hold more than one line. Many travelers keep their carrier line for calls and texts and add a data-only travel eSIM for the trip. The setup guides below show where those switches are on iPhone and Android, and the destination pages compare travel plans by total price.
"From" is the lowest price we found on the provider's own destination pages (checked Oct 2026). Links go through our /go/ redirect; we may earn a commission.
