I’ve just tried this with the same SIM in a SIMCOM SIM300 module, and the held call can be reconnected with any of: AT+CHLD=1 AT+CHLD=2 AT+CHLD=21 AT+CHLD=3 ---

An old Fastrack M1306B will reconnected the held call with either AT+CHLD=1 or AT+CHLD=2 657\_09gg.Q2406B 1954500 102706 18:44 So this appears to be a recent SiWi bug. ---
