Reply To: High SDCCH Traffic in LA Borders


Pix said that PLMN not allwed appears by not being acceptable of a IMSI in a PLMN which that IMSI is not registered in that HLR or the HLR/VLR can’t get the response from source HLR.

Then what will yo usay, If I say, I have many sample, that a SIM gets the message PLMN not allowed, from a network. but some minutae later it can register. and this happens many for those SIMs.
