Three deals: This is the BEST unlimited data offer around

This 12-month Three deal via Affordable Mobiles gets you unlimited SIM-only data for a scarcely believable £9.50/mth

Not only is this one of the best Three deals around, but it’s one of the best SIM-only offers overall: you can get a year of unlimited Three 5G data via Affordable Mobiles for a gob-smacking £9.50/mth. You’ll have to claim your saving via cashback, but the process is straightforward and more than worth it to nab this astronomic discount.

To put this deal in perspective, you’d pay £21/mth for a 12-month SIM direct from Three, meaning you’re saving a whopping £138. Meanwhile, the same plan from EE would set you back £37/mth or £35/mth from Vodafone. Even better, Three boasts the most extensive and fastest 5G network in the UK, according to Opensignal’s latest round of tests

In short, this is an unmissable SIM-only deal that you should take advantage of quickly because it won’t last forever.

So what’s Three like as a mobile network? In our most recent Three review, we complimented its value for money, as well as its wide 4G and 5G network, which Opensignal has found to be the largest in the UK. It also now serves up the fastest average 5G download speeds by a country mile, posting 204Mbits/sec to second-place EE’s 129Mbits/sec. That’s a blistering score.

A small caveat is Three’s so-so customer support rating, but the majority of users were still satisfied with their service in our Mobile Network Awards survey. As we briefly mentioned above, another thing to bear in mind is that you’ll need to claim cashback from Affordable Mobiles to get the £9.50/mth plan (if you don’t, it will be £16/mth). Luckily, it’s just a case of occasionally sending an email with your network bill and full instructions can be found here.

And it’s well worth doing so because this Three deal is unbeatable: unlimited data with the fastest 5G download speeds in the UK for under a tenner per month. Again, just make sure to snap it up as soon as possible before it expires.
