I have a motorola v60 tri-band phone which was purchased through t-mobile. The t-mobile account is not active now as I switched to another carrier. I was told that I could use this phone internationally with an appropriate international sim card. It was once "unlocked" by t-mobile for international use through their services. How do I tell if the phone is truly unlocked? I do not have access to another sim card from another account. Since my t-mobile account is not active (it has been permanantly closed) I don't think that calling t-mobile will help.

It would be great to know if this phone will work with an international sim card before actually buying one.

Thanks
