This allows you to stay connected to the internet while traveling without incurring expensive data roaming charges from your home carrier.

Most models in 2026 are roughly the size of a standard deck of cards or a small power bank, making them easy to slide into your pocket or day bag without weighing you down. You simply carry it with you, and your devices stay connected as long as you are within a short range of the router.
