Portable WiFi Hotspots for Travel & Everyday Use in the UK (2026 Buyer’s Guide)
Share
Portable WiFi hotspots give you your own WiFi connection wherever you have suitable mobile network coverage. They’re ideal for travelling, working remotely, caravans and campervans, temporary accommodation, or simply keeping a backup internet connection available.
In this buyer’s guide, we explain what to look for when choosing portable WiFi and highlight some of the best portable WiFi hotspots to buy in the UK in 2026.
What Is a Portable WiFi Hotspot?
A portable WiFi hotspot, sometimes called Mobile WiFi or MiFi, uses a mobile data SIM to create a private WiFi network that your devices can connect to.
Portable WiFi is particularly useful for:
- Travel and holidays
- Working remotely or on the go
- Caravans and campervans
- Temporary accommodation
- Events and days out
- Backup internet at home
Instead of relying on public WiFi or using your phone as a hotspot, a dedicated Mobile WiFi device can connect multiple phones, tablets and laptops to one mobile data connection.
4G vs 5G Portable WiFi
One of the biggest decisions when buying portable WiFi is whether you need 4G or 5G.
| Feature | 4G Portable WiFi | 5G Portable WiFi |
|---|---|---|
| Speed | Suitable for browsing, video calls and streaming | Higher potential speeds for downloads and high-quality streaming |
| Coverage | Widely available across the UK | Depends on local 5G network coverage |
| Battery Usage | Generally efficient for everyday portable use | Power consumption varies depending on the device and signal |
| Price | Usually more affordable | Generally more expensive |
| Best For | Travel, everyday browsing and general use | Users wanting higher potential mobile speeds |
For most everyday travel, a good 4G or 4G+ hotspot can be more than enough. If you regularly download large files, stream heavily or want higher potential mobile speeds, a 5G model may be worth considering when suitable coverage is available.

What Should You Look for When Buying Portable WiFi?
4G, 4G+ or 5G
Think about how much speed you actually need. 4G is suitable for most everyday tasks, while 4G+ can offer improved performance where supported. 5G provides higher potential speeds but requires a compatible hotspot and suitable network coverage.
WiFi Standard
Newer hotspots with WiFi 6 can provide improved wireless efficiency and capacity, which can be particularly useful when several devices are connected at the same time.
Both the ZTE U10 and U10S Pro feature WiFi 6, making them particularly attractive if you expect to connect multiple devices.
Battery Life
If you're buying a hotspot specifically for travelling, battery capacity and expected usage time are important. Consider how long you'll normally be away from a charger and whether you'll have access to a power bank.
The ZTE U10S Pro features a 3000mAh battery with up to 10 hours of use, while the smaller ZTE U10 uses a 2000mAh battery.
Number of Connected Devices
If you're travelling as a family or using the hotspot for work, check how many devices can connect simultaneously.
The ZTE U10 and U10S Pro support up to 32 connected devices, making them useful when several phones, tablets and laptops need to share the same connection.
Network Compatibility
Always check that your chosen hotspot is compatible with the mobile network and SIM you intend to use. Actual speeds and performance will also depend on network coverage, congestion and signal strength in your location.
Do You Need a SIM Card?
Most portable WiFi hotspots require a compatible mobile data SIM with an active data allowance to access the internet.
The amount of data you need depends on how you plan to use the hotspot. Browsing, messaging and email use relatively little data, while video streaming, downloading large files and connecting several users can consume considerably more.
Portable WiFi vs Phone Hotspot
| Portable WiFi | Phone Hotspot |
|---|---|
| Dedicated device for mobile internet | Uses your existing smartphone |
| Doesn't drain your phone battery | Can increase phone battery usage |
| Designed to connect multiple devices | Useful for occasional connection sharing |
| Can use a separate mobile data SIM | Uses your phone's existing data allowance |
| Useful for families and remote working | Convenient for quick or occasional use |
Useful Portable WiFi Accessories
- Mobile data SIM: Choose a data allowance suitable for how often you'll use your hotspot.
- Power bank: Useful for keeping your hotspot charged during long journeys or days away from mains power.
- Protective case: Helps protect your hotspot while travelling.
- Charging cable: Keeping a spare compatible cable in your travel bag can be useful.
Can Portable WiFi Replace Home Broadband?
Portable WiFi can potentially provide temporary or backup home internet if you have suitable mobile coverage and enough data.
However, if you primarily need internet at one property and regularly connect TVs, computers, games consoles and other devices, a dedicated home 4G or 5G router may be a better option.
