Best Three Mobile Deals - September 2021

We have handpicked the best deals on Three for you, including some that will you not find on Three’s website, but you still buy directly from them. These include great value offers on SIM plans, mobile phones, home broadband and tablets.

SIM Only

SIM only deals are great value and can be significantly cheaper than a Pay Monthly phone contract.

Three currently have several offers available, including 4GB data, unlimited minutes, and texts for just £6 a month on a 12-month plan. Those looking for more data should consider the 12GB plan for just £8 a month. Other current offers including 30GB data, unlimited minutes, and texts for £10 a month and unlimited data, minutes, and texts for just £16 a month.

All Three SIM deals come with 5G at no extra cost, free roaming abroad and tethering included.

Home Broadband

Home Broadband is a great alternative to fixed-line fibre because you don’t need a landline or engineer visit. It’s also great value and is now available at the lowest ever price.

The Three 4G Hub can currently be picked up with unlimited data for just £14 a month on a 24-month plan, or £17 a month on a 12-month contract. While the Three 5G Hub with unlimited data now costs just £22 a month on a 24-month contract or £27 on a 12-month plan.

Mobile Phones

Those looking for a new phone will be thrilled to hear that a whole host of great deals are available on Three Pay Monthly phones.

There are far too many to list them all here, but several standout deals are available. These are exclusive deals that won’t find on Three’s website, but you still buy directly from Three.

The new iPhone 13 is available with 100GB data, unlimited texts, and unlimited minutes for £43 a month. Alternatively, you can pickup the iPhone 13 Pro for £51 a month, iPhone 13 Pro Max for £56 a month or the iPhone 13 mini for £39 a month.

Standout deals on Android phones including Samsung’s Galaxy S20 Fan Edition with 100GB of data for £36 a month, or the Galaxy S21 5G again with 100GB data for £40 a month.

A range of more affordable devices are also available so there is a deal for every budget.

Existing customer deals

Existing Three customers get access to exclusive deals when they take out an additional contract (2nd line) as a reward for being a loyal customer. Savings are available on all product ranges, including mobile phones, SIM Only and more.
