Do NOT cancel your contract manually

If you cancel your contract before transferring your number, your number will be permanently disconnected and you will lose it. The switching process automatically cancels your old contract once your number has moved.

How to Get Your SMARTY PAC Code

The quickest way to get your SMARTY PAC code is to text PAC to 65075 from your SMARTY phone. You'll receive your PAC code by text within a minute.

Family / Multi-line Accounts: If you have multiple numbers (lines) attached to the same account, the text-to-switch service often won't work. In this case, you will need to log into your account online or call customer service to request your PAC.

Leaving SMARTY while keeping your phone number is simple. Text PAC to 65075 from your SMARTY SIM to receive your PAC code within one minute via SMS. The code is valid for 30 days. You can also request your PAC through the SMARTY app or by logging into your account on the SMARTY website. Since SMARTY only offers 1-month rolling plans, there are no minimum contract terms and no early exit fees to pay. Provide your PAC code to your new mobile network when signing up, and they will initiate the number transfer. Your SMARTY service will end automatically once the port is complete.

SMARTY STAC Code

To leave SMARTY without transferring your phone number, text STAC to 75075 from your SMARTY phone. Your Service Termination Authorisation Code will be sent via SMS within one minute and is valid for 30 days. The STAC code cancels your SMARTY account without porting your number, meaning the number will eventually be recycled. Because SMARTY operates exclusively on rolling monthly plans, there are no cancellation fees or contract penalties. This is a good option if you already have a number on another network and just need to close your SMARTY account cleanly.

Which Network Does SMARTY Use?

SMARTY is a mobile virtual network operator that runs on the Three network. It is actually owned by Three (part of CK Hutchison), making it Three's own budget-friendly sub-brand. SMARTY customers benefit from Three's network infrastructure, which provides 4G coverage to around 99% of the UK population and an expanding 5G network across UK cities. Three operates the UK's largest 5G network by coverage area, which SMARTY customers can access at no additional charge where available. SMARTY differentiates itself with a no-nonsense approach — there are no contracts, no speed restrictions, and unused data discounts on selected plans where you pay less if you use less data.

SMARTY PAC Code FAQ

Does SMARTY have any contract tie-ins or exit fees?
No, SMARTY operates exclusively on 1-month rolling plans with no minimum contract period. You can leave at any time without paying any early termination fees or penalties. Simply request your PAC or STAC code and switch whenever you choose.
Can I use 5G on SMARTY?
Yes, SMARTY includes 5G access at no extra cost on all plans, using Three's 5G network. You will need a 5G-compatible handset and be in an area with Three 5G coverage. You can check 5G availability at your location using the Three or SMARTY coverage checker before switching.
How does SMARTY's unused data discount work when switching?
On eligible plans, SMARTY offers a discount if you do not use all your data in a given month. If you switch networks partway through a billing cycle, you will not receive a discount for that partial month. It is best to time your switch to the end of your current billing period to maximise any potential savings.
Is SMARTY coverage the same as Three?
Yes, SMARTY uses the Three network so the coverage is identical. You will experience the same 4G and 5G signal strength and speeds as Three customers. Use the Three coverage checker with your postcode to verify signal availability in your area before joining SMARTY.
