SMARTY is offering an unlimited data SIM card for £25/month with no credit check and a one-month rolling contract.
In the UK, SMARTY is currently offering an unlimited data SIM card. For £25/month, customers can get a plan with unlimited minutes, unlimited texts and unlimited data. There are no speed restrictions for using too much data and the plan is available on a one-month rolling basis with no credit check required.
In this article, we’ll review SMARTY’s unlimited data SIM card. We’ll start by looking at their unlimited data plan including what you can do with it, both in the UK and when travelling abroad. We’ll also compare SMARTY’s unlimited data SIM card to alternatives from other mobile networks. Finally, we’ll look at the coverage available on SMARTY and how you can keep your existing phone number when joining the SMARTY mobile network.
Unlimited Data on SMARTY
No Download Limits & One-Month Rolling SIM
SMARTY is a low-cost mobile network in the UK, owned and operated by Three as their low-cost subsidiary. The SMARTY sub-brand specialises in one-month rolling plans, giving you a SIM card with no commitment and with no need for a credit check.
SMARTY’s mobile phone SIM card with unlimited minutes, unlimited texts and unlimited data costs £25/month:
SMARTY’s unlimited data plan works on a pre-paid basis so you’ll pay for each month’s usage in advance. The payment will be taken automatically from your registered credit card or debit card unless you disable the automatic renewal in your SMARTY account. For any out-of-bundle usage (e.g. for international or premium-rate phone calls), you can top-up a separate cash balance onto your SMARTY account.
4G Download Speeds
With SMARTY’s unlimited data plan, you’ll get access to full-speed 4G on the SMARTY mobile network.
On SMARTY, there are no speed restrictions for using too much data. This makes it a little bit different to giffgaff’s £25 goodybag with Always-On data which only provides 4G download speeds on the first 20GB per month. On giffgaff, download speeds are restricted to 384kbps (0.4Mbit/s) between 8am and midnight each day once you’ve used 20GB of data.
Whilst SMARTY doesn’t have any speed restrictions for using too much data, it’s worth knowing about their fair usage limit of 1,000GB per month. According to SMARTY, this is used to identify commercial usage of their services:
We have set a usage cap at 1,000GB. When tested, using a mobile for every minute of every day only used around 1,000GB in a month. Setting this cap helps us to identify any commercial use of our services, which is not permitted by our terms and conditions.
If you’re travelling abroad to another European country, you’ll be able to use up to 19GB of data per month at no extra charge. This is possible when travelling to one of the following 34 countries:
Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, French Guiana, Germany, Gibraltar, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Liechtenstein, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Reunion, Romania, Slovakia, Slovenia, Spain, Sweden and Switzerland.
If you’re travelling outside of Europe, it isn’t possible to use the allowances from your unlimited data plan. Instead, you should check the SMARTY website for information about roaming charges. You should also top-up your account with a cash balance before you depart.
If you’re regularly travelling abroad to non-European countries (e.g. the USA, Australia, New Zealand, etc), it might be worth having a look at Three’s Go Roam Around The World offer instead. This will allow you to use your data allowance at no extra charge in 71 destinations, including many destinations that are outside of Europe.
Tethering & Personal Hotspot
You can tether and hot-spot all of your data with no speed restrictions.
It’s also possible to use a SMARTY SIM card in other devices like your tablet, mobile wi-fi router (MiFi) or 4G home broadband router. In fact, you could even combine SMARTY’s unlimited data SIM card with something like a Huawei B525 router to replace your home broadband connection. With an upfront cost of about £120 for the router and then a monthly fee of £25/month, this is competitive in both price and speed against traditional fixed-line fibre broadband services.
Comparison to Alternatives
At present, there are five mobile networks offering an unlimited data mobile plan in the UK: SMARTY, Three, giffgaff, Vodafone and Virgin Mobile.
In general, it tends to be slightly cheaper when you take an unlimited data SIM card from Three. You’ll also get some extra features like Go Roam Around The World (inclusive roaming in 71 destinations). At £25/month, SMARTY’s unlimited data plan is a little more expensive, though it does come with the extra flexibility of being a one-month rolling deal.
Vodafone offers a range of different download speeds across their unlimited data plans. You’ll get speeds of up to 2Mbit/s on Unlimited Lite, speeds of up to 10Mbit/s on Unlimited and uncapped speeds on Unlimited Max.
giffgaff offers Always-On data on their £25 goodybag, giving you unlimited downloads using coverage from O2. However, 4G speeds are only available on the first 20GB per month, with maximum speeds then reducing to 384kbps between 8am and midnight each day.
Virgin Mobile offers unlimited data using coverage from EE. This is available for £27/month on a 12-month contract. You’ll need to be a Virgin TV or home broadband customer to sign up for the SIM card from Virgin.

Network & Coverage
3G & 4G Coverage from Three
On SMARTY’s unlimited data plan, you’ll get coverage from the Three mobile network. At the time of writing, this equates to 99.8% population coverage on 3G and 98.3% population coverage on 4G.
You can double-check the coverage in your area by entering your postcode on SMARTY’s online coverage map:
SMARTY doesn’t provide any 2G coverage so your smartphone will need to support at least 3G coverage at a minimum. You may have limited functionality when using a SMARTY SIM card in some dual-SIM smartphones.
5G Coverage Launch
At present, 5G coverage isn’t available to customers on SMARTY.
Three, SMARTY’s parent mobile network, has announced the launch of 5G coverage for August 2019. This will initially roll out in London, followed by another 24 towns and cities before the end of the year:
Birmingham, Bolton, Bradford, Brighton, Bristol, Cardiff, Coventry, Derby, Edinburgh, Glasgow, Hull, Leeds, Leicester, Liverpool, London, Manchester, Middlesbrough, Milton Keynes, Nottingham, Reading, Rotherham, Sheffield, Slough, Sunderland and Wolverhampton.
It is yet to be confirmed whether customers on SMARTY will receive 5G coverage at the same time as customers on Three.
Keeping Your Phone Number
If you’d like to keep your existing phone number when joining SMARTY Mobile, it’s a straightforward process to transfer it from your old mobile network.
To do so, start off by ordering your unlimited data SIM card from SMARTY. It will initially come with a temporary phone number assigned to it, allowing you to test out the service before moving your phone number over.
Once you’ve done this, request a PAC Code from your old mobile network. This should be provided to you free of charge within 2 hours of your request.
Once your SMARTY SIM card arrives in the post, and once you’ve had the chance to make sure everything’s working correctly, provide your PAC Code to SMARTY by submitting it through your online dashboard. SMARTY will then schedule the transfer of your phone number, normally within 2 working days.
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:
