Hello i tried the Examples in the Arduino Lib. But i cant connect.
Has Anybody some Knowhow with this Board?

How is the best Start?
2 Antennas testet, both nothing.

My SIM is German Carrier Congstar (Mobilephone with Data, no Onlydatacard), but in the Cellphone the Card works fine without PIN...

While im on testing o got the follwing results...

Example "Bandmanagement":
Current band:EGSM_DCS_MODE
...not changed since i buy the Arduino

Example "PINmanagement":
PIN/PUK locked...try it in a cellphone
-> this i did then, ... and it works without problems and i have data "H"

"TestModem"
...Modem is functoning properly

"GSMscanNetworks"
GSM networks scanner
...thats all, it hangs at this

MODEM.debug();

some OKs...

some Errors...
AT+CPIN?
ERROR

try delay reponse after  set band

GSMBand band;
  band.begin();
  String bandName = band.getBand(); // Get and print band name
  Serial.print("Current band:");
  Serial.println(bandName);
delay(100);
 band.setBand(GSM_MODE_GSM850_PCS);
 delay(100);
 bandName = band.getBand(); // Get and print band name
 Serial.print("Current band:");
 delay(100);
 Serial.println(bandName);

I have the same issue. I use 2 sim cards, a main and a second card. The second card works fine and in debug mode I get the AT+CREG 0,1. The main card stays on CREG 0,0.
