I am using a NovaM R410M modem with a Raspberry Pi.
Latest Hologram libraries and OS is also up to date.
The below work 90% to send an SMS, but sometimes fails with the error “Failed to disconnect from cell network”
recv_s = hologram.sendSMS(number, message)
response_message = hologram.getResultString(recv_s)
logging.info('RESPONSE MESSAGE: ’ + response_message)

What could be causing this?
