Tmobile Wing SIM unlock?

[Shiro]

Can I unlock a Tmobile Wing for use on AT&T without being a Tmobile customer, or having to pay for a sim unlock code?

I was not able to find a free unlock service for the mobile model that you have specified...since you are not a customer with T-Mobile I don't think either they will provide you with a free service.So, you can get a paid unlcok code for your t-Mobile Wing from Wickedunlock.com and remove the network lcok easily.
