Make sure that the voltage on the VBAT pins will never drop below 3.0V, even during a transmit
burst when current consumption may rise up to 2A. If the voltage drops below 3.0V, module will be
power down.

*Note: 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.
