Customers on the lookout for a great mobile deal are in luck as Three Mobile and TopCashback have teamed up to offer a ‘free’ 12-month contract. The one-day flash event provides new Three customers with £120 cashback on a 12-month SIM plan boasting a hefty 120GB of data.
This means the year-long contract from Three can effectively come at no cost. However, those eager to snag this bargain must be swift because it expires at 11:59pm on Monday, 10 March 2025. The SIM-only deal is priced at £10 per month, but thanks to the generous cashback offer, customers can recuperate their outlay by signing up here.
The comprehensive package also includes complimentary 5G, unlimited calls and texts to UK numbers, access to the exclusive Three+ rewards app, and the capability to use your data allowance as a Personal Hotspot to tether other gadgets sans Wi-Fi.
To take advantage of the Three deal, follow these steps:
-
Log in or sign up to TopCashback.
-
Search for Three SIM Contracts or click on this link and select ‘Get Cashback Now’.
-
Proceed with your purchase as usual.
-
Your cashback will be tracked and appear in your TopCashback account within 7 working days.
-
The cashback will become available to withdraw and spend once Three SIM Contracts has paid TopCashback the commission for your purchase.
Opinions about Three Mobile’s service vary widely on Trust Pilot, though some reviews are glowing. A satisfied customer expressed their delight, praising the customer service team: “Their professionalism, patience, and deep knowledge made my experience seamless and stress-free. They went above and beyond to find me the best deal, ensuring I left not just satisfied but genuinely impressed.”
However, some users have reported that Three Mobile’s network connection may not be the strongest in certain areas, so it’s advisable to check the coverage before committing. One user shared their experience: “Signed up last year. Okay, at my house, but there was poor signal around the UK on my travels, so I changed network.”
