4 | This sketch, for the Arduino GSM shield, checks the band
|
---|
5 | currently configured in the modem and allows you to change
|
---|
6 | it.

9 | Usual configurations:
|
---|
10 | Europe, Africa, Middle East: E-GSM(900)+DCS(1800)
|
---|
11 | USA, Canada, South America: GSM(850)+PCS(1900)
|
---|
12 | Mexico: PCS(1900)
|
---|
13 | Brazil: GSM(850)+E-GSM(900)+DCS(1800)+PCS(1900)
