Pocket WiFi routers once ruled the travel data market, but eSIMs have replaced them for many travelers by removing an entire device.
Choosing between them comes down to how many devices you need to connect.
- An eSIM works on one phone, is always with you, and needs no charging or rental returns.
- A pocket WiFi shares one connection across phones, tablets, and laptops, which suits families or groups.
- Pocket WiFi adds rental fees, a deposit, and a battery to manage, while an eSIM costs a flat prepaid price.
- For solo travelers, the eSIM is lighter and cheaper; for groups, one pocket WiFi may still win.
- Pocket WiFi still makes sense for a laptop-heavy work trip.
- Most eSIMs now allow hotspot, shrinking the pocket WiFi advantage further.
Most solo and couple travelers are better served by an eSIM, while families should compare a shared pocket WiFi before deciding.
For a solo trip, the eSIM wins on weight, price, and simplicity.
