Bargain network offers UNLIMITED data for £18 a month – but for limited time only
SHOPPERS looking to switch mobile networks are in for a win.
Smarty has knocked the price of its Unlimited data plan down from £20 to just £18 a month, so now's a pretty good time to jump on it.

BUY FROM SMARTY
If your contract's ended or you're just hunting for a better SIM-only deal, Smarty is well worth checking out.
The network regularly rolls out limited-time offers, either cutting prices or boosting data, and right now, this Unlimited deal is one of its strongest.
For anyone who chews through mobile data, the Unlimited plan at £18 per month is a no-brainer.
It's excellent value from a fuss-free provider that keeps things simple, no gimmicks, just loads of data and solid savings.
But that's not all.
Smarty's 100GB plan has been bumped up to 200GB per month, doubling your allowance while still costing just £12.
That's a huge amount of data for the price, especially since there's usually a big jump in cost between mid-range plans and Unlimited.
If you're unsure about coverage in your area, you can use Smarty's coverage tool to check signal strength where you live.
There's also a free Ofcom mobile phone checker tool that helps you compare network coverage and find the best option for your location.
And with major providers now switching off their 3G networks to focus on 4G and 5G, it's a good time to make sure your plan and phone are future-ready.
