What is a prepaid data SIM card?

A data only SIM card is a SIM card that doesn't come with any minutes or text messages. You only receive data.

Prepaid data SIM cards are absolutely perfect if you need an iPad SIM and you want to go online but there's no WiFi available.

Those who would use a data-only SIM card are mainly those who have a data-only device, like an iPad or a hotspot device. That way, they can access the internet in areas where WiFi is not accessible. For instance, say that WiFi is not accessible in a certain location but the 4G LTE or 5G wireless network is available.

Someone in need of internet access for business, school, etc. would then be able to secure mobile broadband internet via tablet or mobile hotspot and a bring your own phone plan. That way, the person can connect to the internet and check anything essential.

Data SIM card sizes

There are different sizes of SIM cards. What you need for a SIM card size is dependent on the device you own.

The iPad requires a nano SIM card. While older tablets may require either a micro SIM card or a standard SIM card.

Most SIM cards are 3-in-1 tri-cut, meaning that they're one size fits all. Simply cut the card to the size you need to fit the device.

How to switch to a prepaid data SIM plan

Switching to a cheaper carrier is simple.

  1. Pick a plan. Consider how many connected devices you have and then choose the amount of data you need. Not sure? Get a clearer picture with our data usage calculator.
  2. Prepare to make the switch. Make sure your current account is paid up and in good standing. If you're bringing a mobile hotspot device with you, make sure it's unlocked to use on another carrier.
  3. Set up your new plan. Keep your current carrier account open until your new one is ready to go. You'll get a data only SIM card from your new provider. Follow their instructions to activate your new plan.
