Frequently Asked Questions
A data only SIM is a SIM card plan that only comes with a monthly mobile data allowance. They don’t include minutes or texts. They are usually used on portable devices that you wouldn’t need to call or text from. Examples include laptops, Wi-Fi dongles, iPads, and tablets. Our data SIMs are not strictly data only SIMs, as they come with unlimited texts and data as standard.
No, data only SIMs are not any faster than SIMs that include minutes and texts. Data speed depends on the network and plan you are on, as well as your location.
This entirely depends on the device you are using the SIM with. You will still have a phone number, but the device needs to be able to interpret the SMS texts and calls you receive.
