Why should you switch to a SIM Only deal?
A SIM Only deal offers you a bundle of minutes, texts and data just like a standard mobile phone contract. However, you don't get a smartphone, you only get a SIM card included, which enables you to save money and can also mean a shorter contract.
One of the main reasons to choose a SIM Only plan is to save money. SIM Only plans are cheaper because the operators don't have to offset the cost of a mobile phone, enabling you to get more minutes, data and texts for less.
SIM Only plans also have shorter contract lengths than standard 24-month mobile contracts. 1-month, 12-month or 24-month SIM contracts are available, or you can even choose a Pay As You Go SIM card for even more flexibility.
One final benefit of SIM only plans is they have less strict credit checks compared to pay monthly phone contracts. Making them great for those with bad-credit, or those worried about their credit score being impacted by refusals.
Three SIM Only deals are some of the cheapest available and come with a host of extras you won't get on other networks.

Firstly, all plans are 5G Ready at no extra cost. When 5G becomes available in your area you will be able to enjoy the superfast speeds it brings and until then you can still access Three's 4G network.
Three also offer truly unlimited data plans with no speed caps or usage limits. Personal Hotspot (or Tethering) is included on all plans enabling you to share internet with other devices over WiFi. Similarly, all plans support WiFi calling, 4G Super Voice (or VoLTE) and come with free WiFi on the London Underground.
Three SIM Only plans are available on a 24-month, 12-month or 1-month (30 day rolling) contract lengths. That offers you a lot more flexibility compared to Pay Monthly phone plans which come with lengthy 24 month contracts. 24-month plans offer the maximum savings for those looking for the best possible value. 12-month plans are a good compromise between contract length and price. While, 1-month rolling plans are great for those looking for the most flexibility. At the end of the month the plan will automatically renew (or roll) into the next month, unless you inform Three that you want to cancel.

A 1 month (or 30 day) rolling contract is a great way to enjoy the lower prices of a contract deal without having to commit to a lengthy contract. Contracts automatically renew every 30 days unless you tell Three you want it to end. This makes it great if you are waiting for a new phone to launch, or want to buy a short-term SIM for using abroad.
