SMARTY Contracts: The Good and the Meh

Let’s tackle the big question: “Does SMARTY do contracts?” Nope. And that’s the beauty of it. All plans are 30-day rolling, so you’re not locked in. If you hate it, cancel anytime. But if you’re after a 12-month deal to save a few quid, you’ll need to look elsewhere (check olimit.co.uk for comparison – more on that later).

What SMARTY Does Well

✔ Money-Back Data: Use 8GB of your 12GB plan? Get refunded for what you didn’t use. It’s not life-changing, but it’s a nice touch. ✔ One of the cheapest unlimited plans in the UK. Three’s network means decent speeds, too. ✔ Free SIM Delivery: No upfront costs – they’ll post it to your gaff for free. ✔ EU Roaming: No extra fees for using your data in Europe (capped at 12GB, though).

Where SMARTY Falls Short

❌ No eSIM Support (Yet): Annoying for travellers who want to ditch physical SIMs. But word on the street is SMARTY’s working on it. Check who offers e-sims here.

❌ Three’s Coverage: Great in cities like London, Manchester, or Birmingham, but rural areas can be hit-or-miss. During mass gatherings such as protests, the network may has issues delivering data. Check Three’s coverage map before committing.

❌ Basic Customer Service: No phone support – it’s all done via online chat or community forums.

SMARTY vs. Olimit.co.uk: Which is Cheaper?

If you’re hunting for the cheapest SIM-only deals, sites like olimit.co.uk often highlight SMARTY as a top pick. But here’s the tea:

SIM ONLY DEALS

SMARTY’s unlimited plan (£20) is £5-£10 cheaper than most rivals (EE, Vodafone).
However, if you don’t need unlimited data, olimit.co.uk sometimes lists smaller MVNOs (like 1pMobile or Lyca) with slightly better prices for low-data users.

For example:

1pMobile (EE network): 10GB for £10 vs. SMARTY’s 12GB for £10. Not a huge difference, but EE’s coverage is better in rural spots.

💡 Our thoughts: SMARTY wins for unlimited data and flexibility, but shop around for low-data plans.

Should You Get SMARTY?

✅ Yes if:

You want a cheap, flexible SIM-only plan.
You’re a heavy data user (that £20 unlimited deal is golden).
You’re in a city with solid Three coverage.

❌ No if:

You need eSIMs right now (hold out for their rumoured 2024 update).
You’re in the countryside – check Three’s map first.
You want perks like free Netflix or Amazon Prime (look at Voxi or O2 instead).

How to Get SMARTY

1️⃣ Order a free SIM from their website. 2️⃣ Choose your plan – no upfront payment. 3️⃣ Pop the SIM in your phone and done.

No frills, no fuss.

Rating:

⭐⭐⭐⭐☆ (4/5)

Cheap, flexible, and ideal for data lovers – just don’t expect hand-holding customer service.

There you go – a no-BS review that’s sharper than a Cockney’s wit. Now go save yourself some quid! 🇬🇧📱
