eSIM vs Pocket WiFi for Travel: Which Is Better?

Pocket Wi-Fi devices (also called MiFi, travel routers, or personal hotspots) were the go-to solution for international travellers a decade ago. Today, eSIMs have replaced them for most people. But there are still situations where a pocket Wi-Fi device makes sense. This guide breaks down the comparison honestly.

What is a pocket Wi-Fi?

A pocket Wi-Fi is a small hardware device that contains a SIM card and creates a personal Wi-Fi hotspot. You connect your phone, laptop, or tablet to it via Wi-Fi, and the device handles the mobile data connection. You hire or buy one before your trip.

eSIM vs pocket Wi-Fi: side by side

• Setup: eSIM takes 2 minutes to install via QR code; pocket Wi-Fi requires hiring, picking up, and returning the device
• Battery: eSIM uses your phone's battery; pocket Wi-Fi has its own battery (typically 8-12 hours) that needs charging separately
• Multiple devices: eSIM is for one phone; pocket Wi-Fi can connect multiple devices (great for groups)
• Cost: eSIM is typically cheaper for one person; pocket Wi-Fi rental costs add up, especially with return fees
• Lost/stolen: A lost eSIM is tied to your phone; losing a pocket Wi-Fi device can mean a significant replacement charge
• Coverage: Both depend on local networks -- the eSIM or SIM card inside the device determines coverage, not the hardware

When eSIM wins

For solo travellers and couples, an eSIM almost always makes more sense. It is cheaper, lighter, simpler, and does not require an extra device in your bag or an extra battery to keep charged. You cannot lose it separately, forget to return it, or have it run flat at an inconvenient moment.

When pocket Wi-Fi might make sense

• You need to connect multiple devices (a phone, laptop, and tablet) and an eSIM hotspot would drain your phone battery too quickly
• You are travelling as a group and want to share one data plan between everyone
• You need to connect a device that does not support eSIM (such as an older laptop or camera with Wi-Fi)
• Japan: Japanese pocket Wi-Fi devices have historically offered excellent unlimited data on fast local networks

The verdict

For the vast majority of travellers in 2026, an eSIM is the better choice. It is simpler, more reliable, and avoids all the friction of hardware hire. The only exception is groups who need to share data across multiple non-eSIM devices -- in that case, a shared data plan with a hotspot makes more sense.

Frequently asked questions

Can I use my eSIM phone as a hotspot? Yes. Most phones allow you to share your eSIM data connection as a personal Wi-Fi hotspot. Be aware this will use your battery faster and consume your data allowance more quickly, but it is a free alternative to a separate pocket Wi-Fi device.
