SIM Sizes


Our SIM card comes as a full size SIM card but you can easily pop out the middle to make the SIM card micro or nano sized to fit any device.


If you have a dual SIM handset it’s a great idea to run our SIM card as your secondary SIM. Check if your secondary SIM slot supports 3G data and experience our calls, texting and data across across the Vodafone, O2 and Three networks!
Dual SIMs


Q. How do I get low credit notifications?

If your monthly credit is running low we will contact you. The SIMs have a fair usage policy where our discretion will be used.

Q. Do I get charged for incoming calls?

No, our SIM comes with a UK prefix number so it works like a normal SIM.

Q. Are the SIMs 4G?

Yes, the SIMs are 4G.
