Benefits of choosing Smarty

  • No Credit Check SIM. Smarty SIM-only plans are available without a credit check to every customer. The flexible SIM plans are only 1 month long and are paid upfront so there is no need for checking credit history.
  • Low-Cost & Simple Plans. The no-frills approach to providing 1-month SIM plans means Smarty's prices are much lower than other networks.
  • Refunds On Unused Data If you're a low data user there are some Smarty SIM deals that give you a refund for any unused data every month.

Which Smarty SIM plan is right for me?

Smarty splits their six SIM deals into two loose categories: "Data discount" plans which range from 1GB - 3GB, and their larger plans which range from 30GB - Unlimited data.


Data Discount Plans

These "smaller" SIM plans are 1GB for £6, 2GB for £7 and 3GB for £8 but what makes them interesting and potentially very popular with low-data users, is the refund they give on unused data.

Each month you receive a refund of £1 per unused GB in the previous month. The refund is obviously capped for each plan (eg the 3GB plan can only give back £3 if you use zero data) but for customers looking for a cheap SIM deal it's a really great feature to have!


Larger Plans

They're really showing their Three Mobile heritage here with the large allowance SIM plans. Smarty's largest 3 plans are 30GB for £10, 100GB for £15 (this is a limited time offer and may revert to 50GB at some point) and the excellent Unlimited Data SIM for £20. As with all of Smarty's plans, data allowances are totally unthrottled and the unlimited plan is truly unlimited.


It's worth also noting:

  • Smarty's plans can be cancelled at any time
  • There is absolutely NO credit check required
  • Each Smarty SIM has unlimited texts and calls
  • Each Smarty SIM has unrestricted tethering

Data Coverage & Speed With Smarty

Smarty uses Three Mobile's network and you can check their coverage here


Does Smarty Offer 5G Connectivity?

Smarty's website states 5G connectivity will be happening "soon". Because they run on Three's network it's safe to safe they will have 5G connectivity eventually. If you have a 5G handset already or are considering that you might need a 5G SIM then we suggest you contact Smarty directly for clarification.

Is Smarty a good SIM network for roaming?

Smarty offer free roaming in 35 European destinations on all of their SIM only contracts. If you're planning on going further afield, you will need to "top up" your sim like a PAYG contract and any unused data can be used when you return.

Frequently asked questions

Is Smarty the right SIM network for me?

If you're looking for a simple, no-fuss SIM deal then Smarty are a great choice. Not requiring a credit check means that they provide great SIM contracts for bad credit.


Is a 1-month SIM the only contract offered by Smarty?

Yes, Smarty's plans are kept simple and flexible. 1-month SIM plans can be cancelled or changed at any point..


Do Smarty SIM plans have WiFi calling?

No, Smarty don't currently offer wifi calling.


Do Smarty Plans have free tethering?

All Smarty SIMs allowed unrestricted tethering within the UK - Great for use with their unlimited SIM deal.



Is my data really unlimited on Smarty's Unlimited plan?

Unlimited data plans are truly unlimited with Smarty. Their fair use policy states anything beyond 1000GB/month is considered to be commercial use - Using your phone 24hrs a day for normal usage would just about use 1000GB per month. When travelling in the EU, customers will be subject to a fair use limit of 19GB each month.
