6.2 THE MOISTURE SENSITIVITY LEVEL

The moisture sensitivity level of SIM5300E is 3. The module should be mounted within 168 hours after
unpacking in the environmental conditions of temperature <30°C and relative humidity <60% (RH). It is
necessary to bake the module if the above conditions are not met.
