Out of contract and looking to save some money on a like-for-like, or better plan? Perhaps you're ordering a new phone, such as the iPhone 11, Note 10, OnePlus 7, Google Pixel 3a, Huawei P30, or Samsung Galaxy S10? Either way, then you're in the right place for the best SIM Only deals.

Over the past few years, SIM contracts have seen something of a resurgence. These SIM Only deals allow you to move networks easily and give you great value for money; they're available either on a 12-month, or even rolling monthly plans. 

These SIM-only arrangements are also ideal if your contract is up and you want to save money by not upgrading to a new phone. They're also great if you'd rather buy a mobile phone SIM free and just use EE, Vodafone, Three or O2 for connectivity.
