Are 900-2H681/682 able to receive SMS while online over modem?

Yes, they are able to receive, but only able to process the received SMS after closing an active GSM/HSPA connection!


TM-H devices with a GSM option are able to process SMS only when the modem is not used. If the device is connected to the Internet through GPRS/HSDPA, all SMS sent to the TM-H will be received by the modem but read by device only at the end of the current connection. No SMS will be lost until the internal modem memory is full (if the Operator doesn't buffer the SMS).
