Staying connected while travelling in the UK does not require hotel WiFi or fixed broadband. Whether camping, working remotely or travelling between cities, a portable wifi solution can provide internet access through mobile or satellite networks. The best option depends on your location, data needs, connected devices and network coverage.
What Is Portable WiFi and How Does It Work?
Portable WiFi lets you connect phones, laptops and other devices to the internet without relying on fixed broadband. A portable WiFi device, often called a mobile hotspot or pocket WiFi device and sometimes referred to as MiFi, typically uses a SIM or eSIM to connect to a 4G or 5G mobile network and then creates a private WiFi network that nearby devices can join.
The portable WiFi device itself does not provide internet access on its own—you normally need a compatible mobile data plan or data allowance. Like a smartphone, a mobile WiFi device also depends on cellular coverage, so speed and availability vary by location. In remote areas beyond reliable 4G or 5G coverage, satellite internet is a separate alternative for getting connected.
What Are the Main Portable WiFi Options?
There is no single solution that works for every type of UK travel. Your choice will depend on coverage, portability, battery life, data requirements and the number of devices you want to connect.
Phone Tethering
The simplest option is to use your smartphone as a hotspot, sharing its 4G or 5G connection with other devices. It requires no extra hardware or data plan, but can drain your phone battery quickly. Experimental research found that enabling Wi-Fi tethering increased average power consumption from 20 mW to 270 mW on a Nexus One, even without data traffic, with researchers describing existing tethering systems as “power hungry.”
Mobile Broadband Dongles
A mobile broadband dongle is a compact USB device that uses a SIM card to connect a laptop or PC to the internet through a mobile network. As Vodafone explains, “a data dongle is a simple device which connects to the USB port on your device” and provides internet access via the mobile network. It is convenient for single-device use but less suitable for connecting multiple devices.
Dedicated Mobile Routers
A dedicated mobile router creates a WiFi network using a mobile data connection. Some models have built-in batteries, while others run via USB or mains power. A portable router is useful for campers and remote workers who need to connect multiple devices without draining their phone battery. It can also provide a more stable connection and, on some models, support stronger cellular reception through external antennas.
Satellite Routers
Satellite internet is another option for travellers heading to locations where mobile coverage is weak or unavailable. Instead of connecting to a terrestrial mobile network, satellite equipment communicates with satellites overhead.
Satellite internet can be useful for travellers heading beyond reliable mobile coverage. For campers and remote workers, Starlink’s Roam service is described as being “best for motorhomes, nomads, and campers, and working on the go,” with plans starting from £55/month. Starlink Mini has an average energy consumption of 25–40W, according to Starlink’s specifications.
How to Get Temporary WiFi Without Broadband in the UK?
You can get temporary WiFi without fixed broadband through phone tethering, mobile broadband, or other wireless internet options. This can be useful when moving house, waiting for broadband installation, staying in temporary accommodation, travelling, or dealing with a short-term broadband outage.
For a few hours or days, phone tethering is usually the simplest option because it requires no additional WiFi hardware. For longer periods or multiple devices, a portable WiFi router with a prepaid SIM or rolling data plan provides a dedicated connection without relying on your phone.
If you need temporary internet at home, such as while waiting for fibre to be installed, 4G or 5G home broadband can be a practical option. Some UK providers offer rolling monthly plans, allowing you to use a 4G/5G router without committing to a long-term broadband contract. Availability and performance depend on mobile network coverage at your address.
Whichever option you choose, check mobile coverage, data allowance, number of connected devices, and how long you need the connection. Mobile WiFi still requires a usable 4G or 5G signal; in remote locations without reliable cellular coverage, satellite internet may be an alternative.
How to Choose Portable WiFi for UK Travel, Camping and Off-Grid Use
The best setup depends on what you plan to do online and where you expect to use it. A solution that works well for a weekend city trip may not be suitable for several days of camping.
Network Coverage and Data Plans
Check the coverage map for the mobile network used by your SIM or router before travelling. Coverage can vary significantly between locations, particularly in rural and remote areas, so a network that performs well in a city may not provide the same connection at a campsite or other off-grid location.
Your data allowance should reflect how you plan to use the connection. As a rough guide, one hour of HD Netflix streaming can use around 3GB of data, while lighter activities such as web browsing and email generally use much less. For reference, 1GB equals 1,000MB. If you plan to stream regularly, make video calls or work remotely, a larger data allowance or unlimited plan may be more practical.
Speed, Battery Life and Connected Devices
Consider how many devices will share the connection and what you will use them for. Basic browsing and email require less bandwidth than HD streaming, video calls or large file uploads, while connecting several phones and laptops at once can place greater demands on the connection.
Battery life is especially important for camping and off-grid use. A pocket WiFi hotspot may be convenient for short trips, while longer stays may require a device with longer battery life or an external power source. A travel WiFi router can also allow several people to share one connection without relying on a phone hotspot.
Portable WiFi Cost in the UK
Portable WiFi costs in the UK depend on the device, data allowance and type of plan. If you already have a portable WiFi router, your main ongoing expense will usually be the SIM or mobile data plan.
For example, SMARTY's data-only plans currently range from £5 for 2GB to £20 for unlimited data, with 15GB at £9, 40GB at £13 and 100GB at £17. These are one-month rolling plans with no long-term contract.
For temporary WiFi or occasional travel, a smaller prepaid or rolling data plan may be sufficient. If you regularly stream video, make video calls or work remotely, a larger allowance or unlimited plan may offer better value. Remember that the portable WiFi device itself may be a separate upfront cost, so compare the device price, monthly data cost, allowance and contract length.
How to Keep Your Off-Grid WiFi Powered
An off-grid WiFi setup needs both a connection and a reliable power source. Where cellular coverage is available, a 4G or 5G router or portable hotspot can provide internet access with relatively low power requirements. In more remote locations without reliable mobile coverage, satellite internet may be an alternative, but satellite equipment generally requires more power.
A power bank may be enough for a small hotspot, while larger satellite systems may require a portable power station for extended use. The right power source depends on the equipment you use and how long you need to stay connected.
How Much Power Does Portable WiFi Use?
The power consumption of a WiFi setup varies significantly by device. A small mobile hotspot may consume only a few watts while operating, whereas larger routers and satellite terminals can require substantially more.
A simple way to estimate energy consumption is:
Energy Used (Wh) = Power Consumption (W) × Operating Time (hours)
For example, if an off-grid WiFi setup averages 40W and runs continuously for 10 hours:
40W × 10 hours = 400Wh
Actual energy use can vary depending on the equipment, signal strength, connected devices and network activity.
How Long Can a Power Station Run Your WiFi?
If you're camping or working remotely off-grid, the runtime of your WiFi setup depends on both its average power consumption and the usable battery capacity of your power station. Once you know these figures, you can estimate how long your connection can stay powered.
Use the following formula:
Runtime (hours) = Usable Battery Capacity (Wh) ÷ Average Power (W)
For example, suppose the same WiFi setup averages 40W and you have a power station with 1,000Wh of usable capacity:
1,000Wh ÷ 40W = 25 hours
That gives a theoretical runtime of about 25 hours. Actual runtime will be lower because of conversion losses and the power station's own energy consumption. If your off-grid WiFi setup also includes a laptop or phone, include those devices when estimating your total power needs. This is especially important when planning electricity for camping, where several devices need to share the same portable power source.
For longer off-grid stays, a portable power station can keep your connectivity equipment powered and can be recharged with solar panels where conditions allow. For example, the BLUETTI Elite 200 V2 power station provides 2,073.6Wh of battery capacity, which can support a WiFi setup alongside connected devices such as a laptop or phone.
Conclusion
There are several ways to stay connected around the UK without fixed broadband. Smartphone tethering is simple, mobile routers support multiple devices without draining your phone’s battery, and satellite systems work where cellular coverage is limited.
For occasional trips, your phone may be enough. For regular camping or remote work, a dedicated wifi box for travel offers a more convenient setup when paired with a suitable data plan and reliable power source.
Consider four factors: network coverage, data requirements, connected devices and power consumption.
