The PLMN which is rejected the LU request was same as my HPLMN. But RAT was different. LU attempted on UMTS RAT since the UE is redirected into 3G from 2G. I would like to, Can PLMN reject the LU (#13) if it is with different RAT?. 25th August 2014 at 11:12 #69677 TamilGuest Can I have answer for this?
