Hello, I read in the data sheet at the following link:

That the Wi-Fi kit is optional. I wanted to know how I can buy it

Hello nfrete - welcome to the Forum community. I wasn’t able to find a part number for the optional Wi-fi kit, so I have e-mailed my Product Manager to see if this is something we can order for you. As soon as I have his reply, I will let you know.

Hello nfrete - I apologize for the delay in getting this information for you. The supplier has added the part that has a SIM socket. The part number is IPC2210A-B03M6CW, which is DigiKey part number
