When Three Mobile launched in 2003 it competed with O2 and Vodafone on price and flexibility, two benefits that Three Mobile carries forward on its pay monthly contracts and sim only deals to this very day. While MVNOs like Giffgaff and Virgin Mobile offer sim only packages, not all of them have access to 5G network speeds. Three Mobile features both 4G and 5G sim only contracts that range from cheap plans up to the most sought after unlimited 5G data offers. You can filter by contract length, data type or cost, giving you plenty of options to find the right sim only package.

Three 5G Sim Only Tariffs

View All

Just as Three Mobile was the last of the major networks to roll out its 4G services, it was also the last to announce its plans for its 5G coverage. But with ambitious commitments to cover 80% of the country with 5G network coverage by the end of 2023 Three Mobile offers some of the best 5G sim only plans provided by any UK network. The company features three 5G sim deals for £10 per month or less, though to access all of the cheapest Three Mobile 5G deals you will need to take out the 24 month plan rather than a one month rolling contract.

Cheap Three Sim Only Deals

The cheapest Three Mobile sim only deals start from under £10 per month, with a variety of budget options featured prominently in the network’s sim catalogue. If you set your filter at under £10 the list of applicable deals will automatically appear. As with Three Mobile pay monthly contracts you can often reduce the cost of your monthly premiums if you spread the deal out over a longer contract term. Three Mobile often promotes its sim only plans with free cashback offers, which either appear as credits on your contract or have to be claimed separately. If you are operating on a strict budget then cashback offers like these are excellent ways to reduce the overall cost of your plan.

Three Sim Cards with Unlimited Data

In the world of ever increasing mobile data reliance, having multiple options for unlimited data contracts is a major plus for any network. All of the Three Mobile unlimited data packages can be taken out on one month, 12 month or 24 month contracts, with the network often including promotions on its deals to reduce the monthly cost. Each Three Mobile unlimited data sim only package is 5G Ready, so even if you don’t live in a 5G area you can make the use of 4G data knowing that when you travel to an area with 5G you can still access the network’s superfast speeds.

One Month Rolling Three Mobile Sims

View All

To compete with MVNOs like Giffgaff and Smarty, Three Mobile offers one month rolling sim only packages that cost slightly more per month than longer term plans. Every Three Mobile one month rolling sim only contract is 5G Ready, and start from allowances of 4GB of data. Flexibility is the main user benefit of one month rolling sim only packages, though, as with all sim only contracts, they do require you to already have a phone handset. If your handset used a different network you might have to unlock your phone in order for your new Three Mobile sim only deal to be usable.
