Unlimited SIM deals: Save a SHEDLOAD with this Three offer
This is one of the biggest unlimited SIM deals we've ever seen: sign up for two Three SIMs and you'll save an eye-boggling £330
As unlimited SIM deals go, this is incredible: if you sign up for two unlimited Three SIMs on a two-year contract, you’ll be able to save a preposterous £330. That’s because you’ll be getting one of the SIMs half-price for six months (£11/mth), before the cost rises to £22/mth for the remainder of the contract. Meanwhile, the other SIM will remain half-price (£11/mth) for the whole of the two years. That adds up to just £22/mth for both SIMs for the first six months and £33/mth thereafter – which is unbelievably good value. It’s perfect if you and a member of your family are both looking to save money.
Let’s put it into perspective: a SIM with 24 months of unlimited 5G data would usually set you back £22/mth with Three, £35/mth with Vodafone and £35/mth with EE. Even our favourite budget choice, iD Mobile, charges £16/mth for one SIM, meaning it would work out as £32/mth to buy two.
In short, not only is this one of the best Three offers around at the moment, but it’s also one of the best unlimited SIM deals we’ve ever seen. All you need to do is decide who’s going to be the recipient of bargain bottomless browsing with you. Make sure you get in there quickly too because discounts this delicious don’t usually last for long.
In our most recent review of Three’s service, we praised its value for money and growing 5G network, which Opensignal found to be the widest in the country. It delivered a lightning-fast average 5G download speed of 204Mbits/sec, leaving second-place EE in the dust. Our major criticism is with Three’s comparatively so-so customer support scores, but most users were still satisfied with their service in our Mobile Network Awards survey.
However, the unlimited SIM deals from Three haven’t finished yet. If you only want one SIM, you can currently get unlimited 5G data for just £11/mth for the first six months of a two-year contract (then £22/mth for the remaining 18 months). To sweeten the deal, Three is also throwing in a whopping £100 prepaid Mastercard if you’re switching to the network. Phew!
The double unlimited SIM deal from Three is still our pick of the bunch, though, offering truly extraordinary value for money. Once again, just ensure that you sign up as soon as possible to avoid disappointment.
