Questions

Is there a KiCad symbol and footprint for the SIM808?

Yes. The symbol is EasyEDA_Cloud:SIM808 and the footprint EasyEDA_Cloud:GSM-SMD_68P-L24.0-W24.0-P1.00-TL, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the SIM808?

SMD,24x24mm, with 68 pins. Its footprint is drawn on this page.

Where is the SIM808 datasheet?

SIMCom Wireless Solutions publishes it: the Datasheet link on this page opens it.

Where can I order the SIM808?

JLCPCB lists it as part C126275, with 0 in stock; the sellers' links on this page open their listings.

What can replace the SIM808?

Parts like it in the library: the SIM7000E by SIMCom Wireless Solutions, the SIM7000C by SIMCom Wireless Solutions, the SIM2000C by SIMCom Wireless Solutions and the SIM7000A by SIMCom Wireless Solutions. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the SIM808?

19 boards in 17 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
