Frequently asked questions and legal terms

Data-only SIMs (sometimes referred to as a data sim) are SIM cards designed to provide data and internet access.

These SIMs don't include minutes or texts and are mainly designed for tablets.

Data-only SIMs are the ideal choice for devices that have a SIM card slot, so you can keep connected without WiFi.

Our plans are available with deals on 4G and 5G connectivity to make sure you get the fastest experience.

Data-only SIM cards will function in a phone.

However, you won't be able to make calls or send texts.

Data-only SIMs can't receive or send text messages.

The purpose of a data-only SIM is to provide internet access while you're out and away from home.

However, because you receive a phone number with a data-only SIM, you can use WhatsApp.
