Scenario 2:we used a Samsung Galaxy SIII handset to refill a new voucher by using the same USSD but the operation failed and we got the following pop up Message: “ Call barring Connection problem or invalid MMI code All outgoing for All Basic Services” Refer to the trace files on MSC. The main problem is in the register message. – When we used the SII handset the operation code is: activateSS (12) — But when we used Nokia 6020 the operation code is: processUnstructuredSS-Request (59) Why the network read the same message from different handsets in different way? Note : Ericsson Access network and Huawei Core Network. Thank you Author Posts Viewing 1 post (of 1 total) The forum ‘Telecom Design’ is closed to new topics and replies.
