Activating the SIM card that comes with your CheckFox 2.0

The device does not use up a lot of data so the prepaid SIM card should last a while, but in case you need to recharge it, you can do it in this account too. Or you can use your own data SIM card, of course, just make sure to change the APN settings accordingly.
