As said on the chat verbatim:

Through conversations in MicroPython, this part came-up: https://www.lcsc.com/product-detail/2G-3G-4G-5G-Modules_SIMCom-Wireless-Solutions-A7680C-LAAS_C2981435.html

It is a lot less expensive than the alternatives like Quectel EC25 Some module for it would be $20 shipping and antenna included: https://www.aliexpress.com/item/1005005131888666.html

Important point: The A7680C-LAAS module in particular is only working with Chinese network standards. There might be an equivalent module for different zones. Worth checking before picking the actual part.
