AirPrime Q2687RD

The Q2687 Refreshed Intelligent Embedded Module is a self-contained E-GSM/DCS/GSM850/PCS 
GPRS/EGPRS 900/1800/850/1900 quad-band embedded module. It supports the Sierra Wireless 
Software Suite, the world’s most comprehensive cellular development environment which allows 
embedded standard ANSI C applications to be natively executed directly on the embedded module. 
For more information about Sierra Wireless Software Suite, refer to the documents listed in section 
13.2 Reference Documents. 
The Q26SM703RD is the embedded SIM (ESIM) version of the Q2687 Refreshed. It allows the use of 
two different SIMs – an external SIM and an embedded SIM. Note that the ESIM application has to be 
personalized by the card-maker. 
Note that this document only covers the Q2687 Refreshed Intelligent Embedded Module and does not 
cover the programmable capabilities available through the Sierra Wireless Software Suite.
