Detailed Steps
Unscrew the four upper screws from the yellow cover of the hub.
Carefully remove the cover by flipping it over.
Be cautious! The hub's battery is attached to the cover, so avoid pulling too harshly. Also, the screws securing the cover may fall out when flipping it over, so make sure you're over a flat surface where the screws can easily fall.
Disconnect the two micro USB cables opposite the fan.
Insert your SIM card correctly into the second slot of the Hub (beneath the pink tier).
Reconnect the micro USB cables.
Gently reposition the yellow cover on the hub.
Screw the four screws back into the cover to secure it to the base.
Turn on the Beekee Hub.
