I would like to send an SMS to a registered mobile phone from the code running in STM32 board.
Hello,
I haven't checked the compatibility pin by pin, but here is an Arduino expansion board available: A000043 ARDUINO, SHIELD, ARDUINO, GSM, INTEGRATED ANTENNA | Farnell element14
STM Nucleo boards feature an Arduino expansion port, so this might broaden the area where to look.

The A000043's page mentions that it is no longer manufactured. Otherwise it appears to be very useful.
Sorry, my bad.
There seems to be a newer version, but I can't find it in Farnell catalogue: https://store.arduino.cc/arduino-genuino/arduino-genuino-shields/arduino-gsm-shield-2-integrated-antenna
