How do I check whether a subscriber has subscribed to the GPRS

Run the LST GPRS command with the subscribers IMSI specified. If the command output contains a context ID and an APN, the subscriber has subscribed to the GPRS.

 

in the MSC or HLR ?

It is checked from HLR.

output will give the total status of the subscriber.
