Welcome to SA Tech Help
Does it require a special modem installation for it to work. I got it second hand and I do not know if any such modem may still be there even if it was installed from factory. Thanks

Hi. Please note that you will need to have a WWAN (Wireless Wide Area Network) Modem to work together with the SIM card slot under the battery. Alone, the SIM card will not be anough for connectivity. Please comment below if you have a WWAN modem listed under Device Manager.
