I was trying to use my Nexus S which I bought from koodo online shop with other networks. I used a fido sim, ekit sim (which is supposed to work with Nexus S) and a sim from another country but non of them worked. Then I thought the phone is locked, so I tried unlocking both through Koodo and a third party. In both cases, they said the phone in unlocked. Interestingly, I can not even upgrade my phone on the self serve website as it says that my IMEI is not valid. I want to know what I should do?

It will work on most networks not all. Which are you trying?
