I am curious as to whether anyone else has attempted to use this device to dial up a digital service provider. I see where the AT manual says that the command sequence is simply ATD followed by the number and a semicolon. I try and get nothing but "error" even with CMEE=2 its still the same cryptic "error" message. I'm thinking there is a mode issue to be addressed. Any insight is appreciated.
If you want to make voice calls i have bad news: Arduino did not connect the I2S pins from the modem. I don't know why and i asked a several time in this forum to do so. It would be sooo easy like they did with the MKR1400....
So if you want to make voice calls, you have to take a MKR1400.
