Fipy, is LTE.deinit needed after every deepsleep?

[bramelfvering]

I'm using a fipy to send some sensor data with LoRa after which it goes into deepsleep for 15 minutes.
The first time the fipy boots up i deinit the LTE-m modem. Which takes about 4 seconds.
if my code detects a deepsleep reset, it skips this lte-m deinit.
Do i have to deinit the LTE-m modem after every deepsleep even though i don't us it in my code.
I can't find any documentation if the LTE-m modem inits after a reset like the WLAN does even though i don't use it.
