Unlock Alcatel Goflip 4 for any carrier

I bought an Alcatel Goflip 4 from T-Mobile almost 2 years ago. I want to use it with a sim card from a Canadian carrier when I am in Canada. I have had multiple contacts with T-Mobile tech support and have been given four different unlock codes, none of which have worked. Has anyone been able to unlock one of these devices to use with other carriers?
