Grandfather was given this phone to replace his broken one, tossed his SIM in and its asking me to unlock it from Koodo, he cant remember who gave him the phone and unfortunately I dont live near him.

Is there a AIO lock code for these things?  I tried searching online but its all asking for money to unlock it and because I’m not a Customer, I cant unlock it via Self Help?

Current wait for a callback is 2 hours, currently in que .  Wondering if anyone here has any ideas or can help?
