I have the same problem, the SIM card can’t be detected. Bending the pins a little bit changed nothing.
The sim card works fine in my Samsung Galaxy S3 Smartphone.
VMINT number_count = 0; number_count = vm_gsm_sim_get_card_count();
returns the value “-103”.
Which I think it means:
#define VM_SYMBOL_NOT_FOUND (-103) /* The error code (-103) means a symbol cannot be found in the firmware. */
returns the value “0”.
I’m using a sim card from “congstar.de”, it’s a provider that uses the t-mobile network.
