Mobile station class B can connect to both GSM and GPRS, but only one connection may be used at a time.
During GSM service (voice call or SMS), GPRS is suspended, then resumed automatically after the GSM is
concluded. The consequences are:
- receiving SMS is postponed and voice calls are blocked while GPRS is active (outgoing SMS is not affected)
- remote GPRS connection is not possible while voce call is active
