Am currently using Glo sim on my BlackBerry z30, due to d end of whatsapp on BlackBerry, I intend to change my phone and my network, cos glo 3 gig work fast mostly on BlackBerry, and now due to the poor network and all the stress, I intend to reward my self by borrowing airtime, lavish it on calls before porting to another network.

Will a borrowed sim be allowed to port to another network? Even if it works, will it affect my current network?
Please people that have experience it or done something like that should please enlighten me.
