Ang nasa isip ko lang paps eh since openline ko sya nabili.matagal kona rin hindi nagamit dahil nawala nga ung unlidata ng sim ko.I think this problem already existed since last March this present year, where Smart locked access to the DEFAULT SIM ONLY of their Prepaid Wifi Modems. Making it hard to insert another Smart SIM Cards and I have not seen any workaround since but to change the IMEI of the device. I think a few threads here have topics to change IMEI's, feel FREE to search it ts.
