Broadband for 6th generation iPad

Do you have a WiFi Only or WiFi+Cellular model of iPad?

If you have a Cellular model, you simply need to arrange a pay-as-you-go Cellular plan with your chosen Cellular provider - who will provide a SIM card.

Alternatively, if you have a WiFi Only model of iPad, many Cellular providers offer Mobile Broadband routers to buy (also known as MiFi) which provide a WiFi hotspot. Again, you will need to add a suitable Cellular plan - either pay-as-you-go or contract.

depend on what equipment they give you, if it's an usb dongle with a sim card then no

if it's a small wifi router box with a sim card then yes, if it's a wifi router box with a cable to fiber or adsl or the likes then yes.
