Overview

What is a data only SIM deal?

A data SIM is like a standard SIM for your phone, but it only comes with internet (or data) and does not include minutes or texts. They are used in tablets, iPads and mobile devices such as dongles and MiFi routers.

Unlimited data only SIM

At the current time Three don't offer unlimited data only SIM plans, but they do have plans with a whopping 20GB of data allowance per month.

However, please note Three do offer unlimited data on their SIM Only plans for phones.

Which type of SIM Card do I need?

Devices support different types of SIM, with either a standard, micro or nano SIM required. You can check with your manufacturer website, or if in any doubt you can always call Three free on 0800 358 9048.

  • Standard SIM - For use in the majority of mobile broadband dongles and MiFi devices.
  • Micro SIM - For use in many more modern tablets such as the Apple iPad, Apple iPad 2 and the Apple iPad 4.
  • Nano-SIM - For use some of the latest devices including the iPad Pro, iPad Air, iPad Air 2, iPad Mini 2, iPad mini 3 and iPad Mini 4.

Why Choose SIM Only?

Why choose a Pay Monthly data SIM?

Pay Monthly plans have a number of advantages over standard tablet and mobile broadband contracts;

  • Shorter Contract Lengths - The majority of tablets and mobile broadband devices come on 24 month contracts, but SIM plans are available on 1 month or 12 month contracts.
  • Keep your existing device - If you already bought and paid for a tablet or dongle you are happy with then why buy another one and pay more than you need to?
  • Great Value deals - Because Three don't have to cover the cost of the tablet or dongle they can pass on the savings to you the customer.

Why Choose a Three data sim deal?

  • 4G at no extra cost - All Three plans come with 4G at no extra cost. Don't have a 4G device or aren't in a 4G coverage area? Don't worry you can still enjoy Three's superfast 3G network.
  • Free Roaming Abroad - Use your internet abroad at no extra cost in 19 Feel At Home destinations.
