How do you use a mobile data plan on your laptop?
Use a 4G dongle
For internet via a 4G dongle, you have to use a SIM card with a mobile data plan. You place the SIM card into the 4G dongle, which you then plug into the USB-A port of your laptop. You can use the SIM card of your mobile phone, if you have a mobile data plan. You can also buy a separate SIM card with just a data plan.
Take your MiFi router with you
With a MiFi router, you can set up a wireless network via a mobile provider. You need a SIM card with a mobile data plan for that. A MiFi router is more than the mobile internet solution for just your laptop, because you can use the network of the MiFi router with multiple devices at the same time. So with a single router, you can send your email with your laptop and check out recipes for dinner via your tablet.
Connect to a public WiFi network
To use internet on your laptop on the go, you can look for a public WiFi network. You can usually find one in trains and restaurants. You can connect to such a network for free. To confirm the connection, open the browser on your laptop and follow the steps that appear automatically.
Note: a public WiFi connection isn't secure. Never sign in with your back information on a public network, for example.
Use the mobile hotspot of your phone
Do you have a phone with a mobile data plan? If so, you're ready to use the internet on your tablet. The technology behind this is called tethering, which you can find via your phone settings. You can connect to the mobile network of your phone by connecting your phone to your laptop with a USB cable, or simply connect wirelessly via WiFi or Bluetooth.
Go for a 4G laptop
LTE laptops have a special module built-in that makes mobile internet (4G) via a SIM card possible. You don't need a dongle for that, but can simply insert a SIM card with a mobile data plan into a slot on your 4G laptop. You can leave the SIM card inside and use 4G internet every time you open your laptop.
