I’m trying to find out if the " Arduino & Raspberry Pi b-gsmgnss Quad-Band GSM, Dual SIM, GNSS, Bluetooth Shield" device will allow the Raspberry Pi 4B to initiate calls, to a nework modem, for example; in situations where there isn’t your favorite Starbucks or Chick-Fil-A wifi link but there is cell phone coverage. A store-and-forward device, for example. And, conversely, can the same shield allow incoming calls to bring the Raspberry Pi 4B onto a network under the same environmental conditions?
Hi Weedware,
Welcome to the forum.
This isn’t mentioned in the product specifications.
I believe you would be better to contact the manufacturer to obtain all the answers to your questions: [email protected]
