Why Choose Mobile Broadband Over Fibre?

Traditional fibre broadband needs a phone line, an engineer and a socket drilled into your wall. Mobile broadband arrives in the post, works the same day, moves house with you — and is often cheaper.

No Engineer Visit

Your SIM card arrives by post. Insert it into your MiFi device and you're online in minutes — no waiting weeks for installation.

Works Anywhere

Take your broadband wherever you go. Perfect for renters, rural properties, caravans, offices and temporary accommodation.

Router Included

Your 4G/5G router comes with the package and lands on your doormat ready to go. No line rental, no setup fees, no activation charges — the price you agree is the price you pay every month.

Cheap Broadband FAQs

Do you offer rolling monthly broadband?
Yes. Broadband Lite and 5G Premium are available on a rolling monthly contract: a 1-month minimum term, then it carries on month to month until you give 30 days' notice. Broadband Lite is from £25.95/month and 5G Premium from £38.95/month on Three, with the router included.
Is a rolling monthly plan still a contract?
Yes. It is a 1-month contract that you sign online and pay monthly by Direct Debit. There is no long minimum term to sit out — after the first month you can leave whenever you like by giving 30 days' notice.
How do I cancel a rolling monthly plan?
Give 30 days' notice using the online Cancel Contract page in your Silux Mobile account, or email info@siluxmobile.co.uk. Your service and payments stop at the end of the notice period.
What is the cheapest broadband in the UK?
Silux Mobile mobile broadband starts at £15.95/month on a 24-month plan — either Broadband Lite on Three or our portable MiFi. No landline is required and the router is included and delivered to you. Prefer a shorter commitment? Plans start from 1 month — rolling monthly Broadband Lite is £25.95/month with 30 days’ notice to leave — and 3-month plans are from £19.95/month plus a £15 refundable holding deposit.
Do I need a phone line for cheap broadband?
No! With Silux Mobile mobile broadband, you use a MiFi router or a 4G/5G router with a SIM — no phone line, no engineer visit, nothing drilled into your wall. Your router arrives by post; plug it in and connect.
How fast is cheap mobile broadband?
Our 5G mobile broadband delivers speeds of 80–400 Mbps. On 4G, typical speeds are 10–50 Mbps with Broadband Lite and 50–150 Mbps with 5G Premium. This is fast enough for HD streaming, video calls and working from home.
Is mobile broadband reliable for rural areas?
Yes — mobile broadband is often the best option for rural areas where fibre isn't available. Our Three network covers 99% of the UK population outdoors, including rural areas where fixed-line broadband struggles.
How long is a Silux Mobile broadband plan?
You choose, from 1 month: a rolling monthly contract from £25.95/month (1-month minimum term, 30 days’ notice to leave, £30 refundable holding deposit), or a fixed 3, 6, 12, 18, 24 or 36 months. Longer plans get the lowest monthly price — Broadband Lite is £15.95/month over 24 months — and 3-month plans start at £19.95/month plus a £15 refundable holding deposit. Whichever term you pick, the price is fixed for the life of the plan and the broadband moves with you if you move home.
Will my broadband price increase during my contract?
No. Your price is fixed for the life of your plan — there are no price increases during your contract and no annual inflation-linked price rises. What you sign up at is what you pay.
Are broadband upgrades free?
