Why my phone number didn't change on my information when receiving parcel, that sim card is having a signal problems especially its globe.....i switched it to TNT so that i can receive call whenever my parcel arrived, BUT WHY is the contact number didn't change even when i change it before ordering, its already been a week when i change it, but it didnt change.....the number did change in my profile but the number that is being use did not change so im having a problem receiving calls
