Questions

Is there a KiCad symbol and footprint for the SIM7100A?

Yes. The symbol is EasyEDA_Cloud:SIM7100A and the footprint EasyEDA_Cloud:GSM-SMD_87P-L30.0-W30.0-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 SIM7100A?

SMD,30x30mm, with 87 pins. Its footprint is drawn on this page.

Where is the SIM7100A datasheet?

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

Where can I order the SIM7100A?

JLCPCB lists it as part C126260, with 1 in stock; the sellers' links on this page open their listings.

What can replace the SIM7100A?
