Calling within the UK
Whilst in the UK, the included Unlimited minutes and texts can only be made to standard UK landline numbers (for the UK starting 01, 02, 03) and mobiles within the UK. Calls to other numbers including Premium rate, Business rate numbers and non-UK numbers are not included.International Calling
In order to make international phone calls from the UK, you will need to add credit to the sim card. You can only add credit whilst you are in the UK at 3 UK stores, supermarkets, petrol stations and convenience stores. Unfortunately, you are unable to top-up online via the 3 UK website, as it requires a UK debit/credit card that is linked to a UK residential address.
Alternatively, we recommend that you use data based apps such as Whatsapp, Viber, Skype, etc to make international phone calls rather than adding credit for international calls.
Please note: Adult content and apps that ThreeUK have deemed as adult content is blocked on this sim.
If you are travelling with another person it is important to have the ability to contact one another at any time especially in an emergency. We highly advise that you both purchase a sim card so you can keep in touch.
International SIM cards require your phone 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 we will do our best to inform you of any changes as soon as they arise.

This UK SIM Card plan will last 30 Days from activation. If you are staying longer than 30 days, 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 3 UK stores, supermarkets, petrol stations and convenience stores. Unfortunately, you are unable to top-up online via the 3 UK website, as it requires a UK debit/credit card that is linked to a UK residential address.
However, we advise that you visit a 3 UK store when recharging, as this will ensure that the recharge has been done correctly and you have received the most appropriate plan.
Alternatively, as another option if you are travelling for longer than 30 days, you can purchase additional sim cards based on the duration of your travels. If you are travelling for 60 days you can purchase 2 separate sim cards, and then swap them over at the end of each 30 day period (however, each sim card will have a different phone number).
