Three Mobile Sims - Sim Only Contracts from ยฃ5

Three Mobile Logo

Browse a wide range of SIMs and cut the cost of calling, texting or browsing by earning cashback with our 3 mobile deals. If you are happy with your existing Apple iPhone, Android or Windows device, whether you have a Samsung Galaxy S8, HTC or Huawei, and do not want to pay an upfront cost for the latest model, you can take up a SIM plan offering all-you-can-eat texts and which run for either one or 12 months.

If you want to switch to one of Three's Essential or Advanced Plans from another network, you can keep your existing phone number, enjoy a great Internet experience with 3G or 4g and make use of Wi-Fi texting and calling when using the Three inTouch app. As well as SIMs, Three also offer pay monthly and pay as you go mobile phones, mobile broadband, tablets and dongles, while existing customers can browse upgrades if you do want one of the latest devices.

All You Can Eat and Feel At Home


Three's contract SIM deals offer a range of great benefits if you do not want to change your mobile phone. If you choose an Advanced Plan, you can use all of your data allowance as a personal hotspot in the UK, unless you have opted for one of their all-you-can-eat data plans, in which case you will be able to use up to 30GB as a personal hotspot.

All of the plans come with unlimited texts, which will allow you to send as many standard rate text messages as you like in the UK, while if you are on one of the Advanced Plans, you will be able to send up to 5,000 standard rate text messages to the UK each month from any Feel At Home destination.

Feel At Home is available in 60 destinations, from Spain to New Zealand, and also allows you to use your data allowance, text and make calls to the UK from abroad at no extra cost. Take advantage of 4G at no extra cost if you have a 4G phone and are in a 4G coverage area, while if you run out of data part way through the month, you can buy more in your My3 account.

Make sure you never spend more than you planned thanks to their fixed data allowances and usage alerts for minutes and data, while if you do run out of minutes, you can block outgoing calls. You can also block calls and texts to numbers which always fall out of your allowance.
