There are three common ways to get data abroad: a travel eSIM, a local physical SIM, or a pocket WiFi device. Here’s how they really compare.
Travel eSIM
Best for most travelers. Buy online before you go, install by QR, keep your home number, and connect the second you land. Nothing to carry, nothing to charge. Browse CometSIM plans by destination.
Local physical SIM
Often cheap locally, but you must find a shop, show ID, swap your card (and risk losing it), and you lose your home number while it’s in. Not ideal if you land late or move between countries.
Pocket WiFi
Shares data with several devices, but it’s an extra gadget to rent, carry and recharge — and if it dies or gets left behind, everyone is offline.
