WNC IMS2 3.3V Supply Voltage

Unsolved

I am working on a design using the WNC IMS2 cellular module. The specifications say that the minimum voltage is 3.3V, however all test current (Amps) ratings are given for 3.8V and 3.8V seems to be the recommended/nominal supply.

 

My question is: will the IMS2 be able to join the LTE-M network properly and transmit/receive data if the supply is 3.3V? Will it have a more limited range than at 3.8V?

 

It would be great if we didn't need to include a DC boost converter from 3.3V to 3.8V
