6.3. Operating and Storage Temperatures
The operating and storage temperatures are listed in the following table.
Table 30: Operating and Storage Temperatures
6.4. Current Consumption
The values of current consumption are shown below.

13
Within operating temperature range, the module is 3GPP compliant.

Within extended temperature range, the module remains the ability to establish and maintain a voice, SMS, data
transmission, etc. There is no unrecoverable malfunction. There are also no effects on radio spectrum and no harm to radio
network. Only one or more parameters like P
out
might reduce in their value and exceed the specified tolerances. When the
temperature returns to the normal operating temperature levels, the module will meet 3GPP specifications again.
