I had a mobile number with another carrier (Rogers). I went on a trip the last 9 months and so didn't continue my plan and lost my number that I have had for 10 years. Now I'm back and ordered a SIM card from Koodo online yesterday. Today out of curiosity I called my old number with a different phone and found it was still unassigned. Is there any way for me to get my old number back and stay with Koodo?
