Help getting MKRGSM1400 to work with BT M2M sim

I am having trouble connecting my MKRGSM1400 with BT "machine to Machine" (M2M) sim

according to BT all i have to do is put in the APN number EEM2M

am i missing something?

const char PINNUMBER[] = SECRET_PINNUMBER; "leave blank" ? const char GPRS_APN[] = SECRET_GPRS_APN; EEM2M const char GPRS_LOGIN[] = SECRET_GPRS_LOGIN; "leave blank" const char GPRS_PASSWORD[] = SECRET_GPRS_PASSWORD; "leave Blank"
