ESIM GLOSSARY

Hotspot / tethering

Tethering (personal hotspot) shares your phone's mobile data with a laptop or other devices — some travel eSIM plans restrict it.

Tethering — also called personal hotspot — lets your phone share its mobile data connection with other devices over Wi-Fi, Bluetooth, or USB. For remote workers it is often the single most important plan feature.

Not every travel eSIM allows it: some providers block tethering entirely, others allow it but count it against a daily fair-use cap. Plans on this site show a hotspot flag whenever the provider's data includes it.

Heavy tethering (a laptop doing video calls and cloud sync) consumes far more data than phone-only use — size your plan accordingly or pick an unlimited plan whose fair-use policy explicitly permits hotspot use.
