update lang...sakin din ayaw na mag 3G hahaha pero method ko kasi nasa modem....Kapag nag failed it means successful yun di na ako maghihintay ng 30mins.....after mag *222*1*1# dapat magfifailed tapos dun kana sa *222*2*1# it's either failed or may mag popup na your roam off is successful sabay reboot or airplane modeAko kasi naghihintay muna ng 30mins bagi mag-unblock, Airplane Mode On the Off, tapos saka magdial for unblocking, tapos airplane mode on and off ulit. Wait hanggang 10 secs, unang kapit niya sa data 3G then magpapalit into 4G.
