How to Activate the Three UK Data Sim?

To activate the sim card all you need to do is insert the sim into your device and turn your device on. The sim will then automatically connect to the network, which will commence your 360 day plan. Please note, you will need to turn ON your DATA ROAMING function in your device before you can use the service.

Additional Sim Card Information:

International SIM cards requires your device to be unlocked, if you are unsure, please contact your service provider for more details.

Plans are subject to change without notice by the carrier but will do our best to inform you of any changes as soon as they arise.

How to recharge?

The UK Data SIM Card plan will last 12 Months from activation. If you are staying longer than 12 Months, you will need to recharge the sim. As mentioned above, if you wish to add credit or recharge the sim you can only do this whilst you are in the UK at ThreeUK stores, supermarkets, petrol stations and convenience stores. Unfortunately, you are unable to top-up online via the ThreeUK website, as it requires a UK debit/credit card that is linked to a UK residential address.

However, we advise that you visit a ThreeUK store when recharging, as this will ensure that the recharge has been done correctly and you have received the most appropriate plan.
