Module is able to make and receive voice calls, data calls, SMS and make GPRS/LTE traffic in -40℃ ~
+85℃. The performance will be reduced slightly from the 3GPP specifications if the temperature is
outside the normal operating temperature range and still within the extreme operating temperature
range.
