SMARTY is offering 50GB data for £10 with no contract & no credit check. You’ll also get 5G coverage at no extra cost.

In the UK, SMARTY is currently offering a massive 50GB of data for £10 per month. Available on a one-month rolling basis with no contract and no credit check, you’ll get access to 99% population coverage from Three. You’ll also benefit from 5G at no extra cost, the promise of no annual price rises and inclusive EU roaming (up to 12GB per month).

In this article, we’ll look at SMARTY’s 50GB plan including what you’re able to do with it and the features you’ll get included. We’ll also look at SMARTY’s mobile network coverage and how you can keep your current phone number when you switch to SMARTY Mobile.


In the UK, SMARTY is a popular mobile network that offers flexible one-month rolling SIM cards with no need for a contract or credit check.

As a special offer that’s running until the 7th November 2022, SMARTY is offering an extra 20GB data per month on their £10 plan. This means you can get 50GB data with unlimited minutes and unlimited texts for £10 per month. You’ll also get 5G at no extra cost on a 5G-ready phone.


This 50GB data plan should include more than enough data for the vast majority of smartphone users in the UK.

At present, the average UK smartphone user consumes around 6-7GB data per month. Therefore, even if you’re a heavy data user, this 50GB plan should give you enough of a buffer so that you won’t need to worry about your usage. For instance, your 50GB data allowance will allow you to browse the web non-stop. Alternatively, you can stream around 10,000 songs or 100 hours of standard-definition video from the internet (25 hours if you’re watching in HD quality).

As an alternative to the 50GB data plan, you can also consider SMARTY’s other SIM-only plans which start from just £5 per month:


For instance, you can get 12GB data for £7 which is a good alternative if you don’t need quite as much data. SMARTY also offers an unlimited data plan for £16 per month.

SMARTY Features

No Contract & No Credit Check

On SMARTY, your 50GB data plan is available on a one-month rolling basis with no contract and no credit check required. This gives you lots of flexibility to change or cancel your plan at any time. Your monthly bill will also be capped by default so you won’t be able to run up unexpected charges by mistake.

If you’d like to make some out-of-allowance calls or if you’d like to travel outside the EU, you can top-up your SMARTY account with Pay As You Go credit.

No Annual Price Rises

In the UK, most mobile networks have an annual price increase built-in to their plan. This price rise can sometimes be as much as 3.9% above the rate of inflation. On many mobile networks, this means you’re likely to see a price rise of around 10% early next year.

In contrast, SMARTY doesn’t have any annual price rises built-in to their plan. They’ve also pledged “not to introduce annual mid-contract price rises”.

Inclusive EU Roaming

If you’re travelling to one of 34 European destinations, you’ll be able to use your SMARTY plan allowances at no extra cost when you’re abroad. This includes your unlimited minutes, unlimited texts and up to 12GB data per month.

If you’re travelling to another destination that’s further afield, you’ll need to top-up your account with a cash add-on before you depart. You’ll then pay SMARTY’s international roaming rates.

Network & Coverage

3G & 4G Coverage From Three

On SMARTY, you’ll have access to 99.5% outdoor population coverage. This is powered by Three’s 3G and 4G networks, meaning you’ll get the same coverage as customers on Three. In recent years, SMARTY has been upgrading their 4G service with technology such as 4G+ so you’ll often be able to get download speeds of more than 20Mbps on 4G.

To double-check the coverage that’s available in your area, enter your postcode on SMARTY’s online coverage map:

If you’re using a compatible mobile phone, you’ll also have access to Wi-Fi Calling and 4G Calling on SMARTY. This will allow you to make better-quality HD phone calls. You’ll also be able to call in more places (i.e. wherever you have a wi-fi connection).

5G Coverage

If you’re using a 5G-ready phone, you’ll now be able to access SMARTY’s 5G network in over 300 UK towns and cities. This gives you average download speeds of more than 200Mbps (around 5-10 times faster than 4G). You’ll also benefit from more network capacity and lower amounts of latency. This should you give a better overall experience.

Tethering & Personal Hotspot

Tethering or personal hotspot refers to the process of sharing your smartphone’s internet connection with another device (e.g. with your laptop or tablet). It’s a convenient way to get mobile broadband on your other devices, allowing you to get connected without the need to look for public wi-fi hotspots.

On SMARTY’s 50GB data plan, you’ll be able to “tether and hot-spot all of your data with no speed caps as long as you’re in the UK”. This can be a good way of using up your additional data if you don’t normally use the entirety of your 50GB data allowance every month.

Keeping Your Phone Number

If you’re switching from another mobile network to SMARTY, it’s easy keeping your current phone number.

Start by ordering your 50GB SIM card from SMARTY’s website. This is only available until the 7th November 2022. The SIM card will initially have a temporary phone number assigned to it, allowing you to test out SMARTY’s service before you move your phone number to it.

Once you’re happy to move your phone number over, you can request a PAC Code from your old network. This is available through your mobile network’s website or app, or by texting PAC to 65075. You can then submit the PAC Code to SMARTY through your online dashboard. Once you’ve done that, your phone number transfer will normally be scheduled for the next working day.

For step-by-step instructions on how to move your phone number to SMARTY, please select your current mobile network from the drop-down menu below:

  • Smarty does not sell vouchers.
    They make topping up by cash unduly complicated.
    They’re basically just trying to lock you in, make it ‘easy’ to hand over your credit/debit card details, but difficult (impossible) to pay as you go,.
