Thank you for the reply.

But as per your explanation, once I initiated MO SMS, I cannot do MO call until MO SMS has been completed. Is that right? But I don’t think that’s the case with most of MS’s.

MS’s are capable of sending the SMS while the call is in progress.

I read somewhere that once call is initiated, SMS would be sent in SACCH.

I suspect that SACCH being used for SMS transaction is only used in this sceanrio: “Sending SMS “after” initiating a call.” Am I right here?

But in my case, I am having trouble to initiate the call during SMS transaction because the SMS’s too big.

How should I handle this case?
