🔒 Closed Postpaid sim on semi-factory unlocked iphones

[fcaltair]

Hello guys,
Meron kasi akong semi-unlocked iPhone 5s at sinalpakan ko ng smart postpaid sim.
Ang nangyari is kakareceive ko lang ng sim and after 4 days when I checked my unbilled charges na shock ako kasi pumapatak dun at biglang nagcredit limit max ako kahit naka off ung LTE Data ko sa iPhone.
My usage so far is for txt lang sa smart numbers (which is unli text and calls to sun and smart networks) and no internet/LTE data usage dahil I have another postpaid plan for that.
So, gusto ko lang sana malaman if its safe to use postpaid sim , either SMART or Globe, sa semi-unlocked iPhones?
Sana matulungan o may makaexplain sakin guys.
Thanks
