Porting from Fido to SO | Technical service details | Consumer forum

I am currently a Fido pay as you go customer. Recently I lost the SIM card along with the phone. Now I'm thinking about switching to SO. I do have another unlocked GSM phone. I can either buy a SO SIM card from someone on the board (with or without an assigned number) or from 7-11 directly (SIM + phone). My question is: would I be able to port my old Fido number to SO? E.g. do I need any information on the actual Fido SIM card in order to do the porting? I am the legal owner the Fido SIM (obviously), but I am just afraid someone might have picked up my lost SIM card and uses it. I do have the PIN for my Fido account which no one else should know. I appreciate any help. Thanks.
