Nadiscover ko lang now...I tried many times kasi may 100pesos na laman yung blocked sim ko...if repost sensya na but i think hindi nman siguro.
CONS: blocked na sa SMS kahit maibalik yung internet
SOLUTION: if my laman na load, just register tru dial tricks using *121#(100% tested).....pwede lodan yung sim then just use dial tricks to register(Not tested)
