Do You Need a SIM Card for a Caravan or Motorhome Router?

So, you’ve purchased a router for your caravan or motorhome. But you didn’t realise that a mobile internet kit actually needs a SIM card. Yes, every Falcon router needs a data SIM, or an eSIM on the 5G routers, to connect to the internet. This guide is going to tell you exactly what kind of SIM card for your router you need and how to get online as quickly and simply as possible.

Why Every Caravan and Motorhome Router Needs a SIM Card

A mobile internet kit for a caravan or motorhome has two parts working together.

The antenna picks up the 4G or 5G mobile signal from nearby network masts. The body of a caravan or motorhome can weaken mobile signal, which is why a phone inside the van can struggle or show no service. An antenna positioned outside the vehicle can help the router receive a usable signal where a phone inside can’t.

On a roof-mounted kit, the antenna sits outside and above the vehicle body. On a portable kit, you place the antenna in a window or outside, and you can move it to wherever reception is better. Either way, the benefit is improved reception where a usable network signal is available.

The router is a WiFi router with a SIM card slot. It takes that mobile signal and turns it into a private WiFi network inside your van. Your phone, tablet, laptop, and TV connect to the router’s WiFi like at home, and the router uses the SIM card to access the mobile data network. That’s movie nights and gaming sorted.

Without the SIM card, the router doesn’t connect to the internet. The antenna and router work, but data doesn’t pass through. The SIM tells the mobile network who you are and that you’re entitled to use their data.

This is why every Falcon router kit says “SIM not included.” The SIM is the data connection. Every Falcon router is unlocked, so you can connect to any UK mobile network.

Do I Need a Separate SIM?

Not always. You may already have a suitable SIM. You can use the physical SIM from your phone, provided it fits the router and your network’s tariff permits use in a router. The 4G kits take a standard-size SIM and the 5G kits take a nano SIM. If your phone uses an eSIM, it can’t simply be moved into the router.

This is particularly useful for couples travelling together. If one of you has a large or unlimited data allowance, you may be able to place that SIM in the Falcon router and share the connection between your phones, TV, tablets and other devices.

Family can still call the other person’s mobile. The phone without its SIM can keep using internet-based services such as WhatsApp over the router’s WiFi. Normal calls and texts to that SIM’s number won’t arrive on the phone while the SIM is out of it.

When you leave the vehicle, you can put the SIM back in your phone, or connect to your partner’s mobile hotspot.

The main benefit is simple: you use the data allowance you already pay for, without automatically buying another SIM or taking out another contract.

What Kind of SIM Card Does the Router Take?

A SIM card for a WiFi router needs a data allowance and a plan your network allows in a router. That can be the SIM from your phone, or a data SIM made for mobile broadband, not calls and texts. Most mobile networks offer data SIMs, either as pay-as-you-go or on a monthly contract.

Confirm with any network that the plan allows use in a mobile broadband router. Some consumer plans allow for smartphone use only and may restrict or throttle data when used in a router.

Falcon’s 4G kits use a 150Mbps router that takes a standard-size physical SIM. Falcon 5G router kits (the EVO MOBILE 5G, EVO FLEX 5G, and EVO DTV 5G) accept either a nano SIM or an eSIM.

A physical SIM is a removable card that you insert into the router. An eSIM is downloaded electronically instead: you scan a QR code from your network and activate it on the router. Check that your provider supports the router’s eSIM setup and permits router use. More networks offer eSIM data plans, which makes setup even quicker.

Two Ways to Get Connected

Bring Your Own SIM

Because every Falcon router is network-unlocked, you can use any UK network. Slide it into the router’s SIM slot (or activate an eSIM plan on the 5G routers), and start using the data.

The Ofcom Mobile Coverage Checker lets you check 4G and 5G coverage by network at any postcode or location. This is useful if you have regular pitches or touring routes and want to pick the network with the strongest signal there.

When choosing a SIM to use in your Falcon router, check:

Allowance

How much data do you actually need? That depends on how often you tour, what you use the internet for, and how many people share the connection.

Plan type

Pay-as-you-go suits occasional touring. You top up when you need data and pay nothing when the van’s on the drive.

A monthly contract suits regular touring and usage. Some networks offer 30-day rolling SIMs to avoid contract commitments.

Router compatibility

Confirm with the network that the plan can be used in a mobile broadband router. You should check consumer-facing SIM-only deals, which sometimes exclude router use.

SIM size

A standard-size physical SIM for the 4G kits. A nano SIM or an eSIM for the 5G kits. Check the card size before ordering.

Coverage

Use Ofcom’s checker or the network’s coverage map to verify signal in the places you travel to.

The 120GB EE SIM. Ready to Use. Out of the Box.

When you order any of the six Falcon kits listed below, you can choose the “With EE SIM (120GB)” option.

It is a 120GB preloaded EE data SIM, valid for up to 12 months from activation. No monthly contract and no recurring subscription. It is a Pay As You Go SIM, and it currently adds £60 to the kit price.

The 12 months is how long the preloaded data stays valid, not a minimum contract term. You can use the allowance at any point across the 12-month validity period.

Follow the minimal setup steps and connect to EE’s network without a separate plan.

Travelling in Europe: Which SIM Should I Choose?

Staying in One Country

If you’re spending most of your holiday in one country, a local prepaid SIM or eSIM can give you more data for your money than your UK plan’s roaming allowance.

For example, Vodafone Spain’s Prepago M tariff, checked in November 2026, costs €15 for 28 days and is available as an eSIM. It includes 270GB for use in Spain and a separate 23GB allowance for roaming in the EU, UK and USA. Don’t confuse the larger domestic allowance with the amount available when you cross into another country. Prices and allowances change, so check the latest package details before you buy.

Touring Several Countries

If you regularly cross borders, a UK SIM with suitable European roaming, or a Europe-wide travel data package, may be easier to manage. Roaming allowances can be much smaller than a plan’s UK allowance:

• SMARTY includes up to 12GB of EU roaming data each plan month, including on its larger plans, so it isn’t a high-data option for Europe on its own.
• Lebara includes EU roaming of up to 30GB on its SIM-only plans, subject to the plan’s allowance and its current terms.

Whichever you choose, check the countries covered, the validity, whether the plan permits router use and any roaming restrictions.

Choose a Falcon System to Suit Your SIM

For eSIM flexibility, choose the Falcon EVO MOBILE 5G with the 3400Mbps router. It supports both downloadable eSIM profiles and a physical SIM, so you can buy a compatible local or travel data package online without visiting a shop or changing a card.

If you’re happy to use physical SIM cards and want a lower-cost system, the Falcon 4G range remains a practical option. It can use a suitable UK roaming SIM or a local physical SIM. Its 150Mbps router takes a standard-size SIM, so check the card size before you buy.

Either way, you choose the data provider and package that suit your journey, without automatically taking out another long-term contract.

How Far Does 120GB Actually Go?

Most use streaming as a reference point.

According to Netflix’s data usage guidance, standard-definition streaming uses up to 1GB per hour per device, and HD streaming uses up to 3GB per hour per device.

Used entirely for streaming on one device, a 120GB allowance gives you approximately:

• 120 hours of standard-definition streaming, which is just over four hours a week across a 28-week touring season.
• 40 hours of HD streaming, which is around an hour and a half a week over the same period.

These are illustrative figures.

Standard definition is a practical way to make the allowance last longer. Dropping Netflix from HD to standard definition saves up to 2GB per hour per device. On smaller 19 to 27 inch camping TVs, viewed from a typical seating distance, the difference can be less noticeable. It’s worth setting the video quality in your streaming apps while you’re on mobile data.

Every device sharing the WiFi draws from the same 120GB allowance. Two people streaming different things at the same time doubles the data consumption rate.

What 120GB Means for Everyday Use

Browsing, email and messaging generally use much less data than video streaming. O2’s guide to mobile data puts 1GB at around 11 hours of browsing, or 16,000 emails without attachments.

On those figures, a 120GB allowance used for one thing only gives you approximately:

• 1,300 hours of general web browsing, depending on the websites and content.
• Well over a million ordinary emails without large attachments.

These are alternative examples of using the allowance. You couldn’t do all of them alongside the full streaming hours above. Actual usage varies with attachments, background updates and the number of connected devices.

120GB can go a long way for touring customers, particularly if you choose standard-definition streaming and manage background data use. For heavier streamers with multiple devices running, monitor usage and consider a contract SIM with a larger allowance.
