RUT950 Can't send SMS

Time goes by and i still can’t send SMS since i don’t remember when (2 years maybe)
It hangs up with “Waiting for response from modem” few minuts later “Failed to send message”
SIM card GSM etc are ok and sending SMS with other equipment.
Attached pictures (phone number was erased)

Who’s the SIM provider?

PL Orange GSM OPerator
