XMAS is proposed on two different series: XMAS01 and XMAS02.

The two series differ mainly on the type of GSM device equipped on these devices. XMAS01 is equipped with a GSM / GPRS full options to four bands can withstand any option or application we developed. XMAS-02 version is a light version of XMAS-01 equipped with a two GSM bands but only some specific functions necessary for some applications have been reduced keeping the essential functions and reducing costs.
And well indeed considering the operating costs at the design stage, because using a GPRS system can be useful if you have an important flow of data as a text message or a call can be useful if you want to exchange data occasionally or for specific events.

XMAS-01 for a professional, sophisticated and complex applications.
XMAS-02 has been designed to operate faster and more ergonomic, but not less reliable.

One of the most important differences is the ability to receive sms. XMAS-01 can receive and send text messages while XMAS-02 is Enlarged to send sms but not receive.
