A globe postpaid plan account was transferred under my name and it has been used for already a year. The set of phone was then also given to me with the sim which was already used. The old number was retained but as I inserted the sim, I cannot make a call or text. Signal is full but sim status displays emergency calls only. I expected since it was just a transfer of accountability, upon handing over of the unit to me, it is already usable. Is my sim not usable because its not yet activated? Thank you very much and please advise.
