/*
Band Management
This sketch, for the Arduino GSM shield, checks the band
currently configured in the modem and allows you to change
it.
Please check http://www.worldtimezone.com/gsm.html
Usual configurations:
Europe, Africa, Middle East: E-GSM(900)+DCS(1800)
USA, Canada, South America: GSM(850)+PCS(1900)
Mexico: PCS(1900)
Brazil: GSM(850)+E-GSM(900)+DCS(1800)+PCS(1900)
Circuit:
* GSM shield
created 12 June 2012
by Javier Zorzano, Scott Fitzgerald
This example is in the public domain.
