I ordered my son his first phone... The preowned iPhone SE. When the phone is turned on or charging it vibrates... Loudly and constantly. It also came with no SIM card. I assumed these phones were in good working order... According to the description they are suppose to be. I did not open the box when it arrived because it was a Christmas.gift ... This has ruined my son's Christmas. I am about to have to make a payment on the plan that we have not had a chance to use at all!! I hope that Koodo can help fix this... And get me a working phone quickly.
