SMARTY Includes It As Standard

The major networks have been hiking prices by up to 8% every April. SMARTY doesn't. Here's what you get from day one.

No Annual Price Rises

EE, Vodafone and O2 all raise prices mid-contract. SMARTY uses 30-day rolling plans — your price stays your price.

Top up, switch plans, check usage, add family members — all in the SMARTY app. No waiting on hold, no branch visits.

Save Hundreds Per Year

Customers regularly report saving £20–£30 per person per month versus big-network contracts. For a family of four, that's £1,000+ a year.

Saving over £25 a month vs my old contract

It has saved me a lot of money — only paying £7/month (SIM only) where I was paying £32/month on a Three contract. The coverage is exactly the same because it uses the same network. I can't believe I didn't switch sooner.

Amazing value — truly unlimited

Amazing value, amazing coverage, brilliant customer service and 100% true unlimited calls and data — unlike other companies that throttle after a certain point. Switched the whole family over and we're all delighted.

Exactly what it says on the tin

Extremely good value for money, decent signal 99% of the time, user-friendly app, and fast data speeds. Been using SMARTY for two years now. No nasty surprises, no bill shock — it just works.

Years of great value, never let me down

Been with SMARTY for quite a few years now. Always found great value for money and it's extremely rare to come across poor or no signal. My wife and kids are all on it too. The group plan management is dead easy.

Switched four family members — best decision

Moved all four of us from EE. Combined saving is around £80/month. Coverage hasn't changed because they run on Three's masts. The rolling monthly thing is genuinely great — my teenager changed her plan three times in a year with zero hassle.

No throttling on the unlimited — actually unlimited

The unlimited data is actually unlimited with no speed cap — I was sceptical but it's been 8 months and I've never been throttled. Works great for hotspotting my laptop when working remotely. Saves me £22 a month vs Vodafone.

Frequently Asked Questions

Can I keep my existing phone number?
Yes. Text PAC to 65075 on your current network (it's free and takes seconds). You'll receive a PAC code — enter this when activating your SMARTY SIM and your number transfers automatically on the next working day. You never lose your number.
What network does SMARTY use for coverage?
SMARTY runs on Three's network, which covers 99% of the UK outdoor population on 4G. If you already get good signal on Three, you'll have the same experience on SMARTY. You can check your postcode on SMARTY's coverage checker before committing.
Can I put my whole family on one account?
Yes — SMARTY offers group plans, letting you manage multiple SIMs from a single account and dashboard. Each family member can have their own plan (different data amounts if needed), and you can manage billing centrally.
Are there any hidden costs or charges?
No. SMARTY publishes all prices upfront with no mid-contract price rises. There are no exit fees and no annual inflation-linked increases. The price you sign up for stays the same for as long as you stay on that plan.
Is the unlimited data actually unlimited — or does it slow down?
It's genuinely unlimited with no speed throttling and no fair-use cap on the unlimited plan. You get full 4G and 5G speeds (where available) regardless of how much data you use. This is different from some networks that slow you down after a threshold.
What if I want to cancel or change my plan?
Because SMARTY is 30-day rolling, you can cancel or change your plan any month with no penalty. Simply log in to the app, pick a different plan for next month, or cancel before your renewal date. There are no exit fees and no questions asked.
