Frequently Asked Question
How can we see in which network the RB900L is actually operating? Is there an AT command? Can we force the RB900L to one of the networks (2G/3G/4G) in case several of these networks are available?

You can check this by AT+COPS? command. Last parameter is "access technology selected" where 0 means GSM, 2 means UTRAN and 7 means E-UTRAN
You can also select the network technology using AT+WS46=x command, below is the description of x parameter:12 - GSM Digital Cellular Systems (GERAN only)22 UTRAN only25 3GPP Systems (GERAN and UTRAN and E-UTRAN) (factory default)28 E-UTRAN only29 GERAN and UTRAN30 GERAN and E-UTRAN31 UTRAN and E-UTRAN
