What is prepaid mobile broadband?

A prepaid mobile broadband can also be called a “prepaid data plan”. It is a prepaid SIM card that only includes data and no calls or texts. You purchase a price plan that gives you a certain amount of data for a certain amount of time. Once your data is used up or the expiry period has passed, you will need to recharge to continue using the service.

Many prepaid data plans are valid for 28 or 30 days, which roughly corresponds to a month. But it is also common for providers to offer 365 day prepaid mobile broadband.

How does prepaid mobile broadband work?

When you order a prepaid mobile broadband, you will get a SIM card that you can place in a tablet, router or laptop. If your device doesn’t have its own SIM card slot, you can also place the SIM card in a dongle, which you then plug into the USB port of the device that you want to connect to the internet.

Tip! Some providers offer eSIM for their prepaid data plans. That means that if your device is eSIM compatible, you could opt for an eSIM instead of a physical SIM card.

Once you have placed the SIM card in your device, it can connect to the internet. This means that you’re not limited to using public Wi-Fi if you want to use your laptop or tablet when you’re travelling. If you want several devices to be able to connect to your mobile broadband, you can put the SIM card in a router or Wi-Fi Hotspot. Wi-Fi Hotspot are small, portable routers that you can bring with you when you travel.
