HI no only blackberry locked with t-mobile or else unlocked one will work with t-mobile sim ..Else if the blackberry is locked to some other network provider then until you unlock your blackberry you can't use it with t-mobile sim ..You can easily unlock your Blackberry mobile using sites like UnBBlock.com here they render unlock code for all blackberry mobile models at reliable cost ..After unlocking your mobile you can freely use it with any GSM sim in any countries ...
