How to recognize if the number is ported to another mobile network?

When establishing a call by an audible signal you can identify whether the number belongs to the network of T-Mobile or is transferred to/from another mobile network. The audio signal is short and can be heard before the establishment of the call, only when transmitted in a mobile network other than that which belongs under the prefix area code.

When T-Mobile subscriber calls a fixed number, the audible signal indicates that the called number is located in the fixed network operator that is not the holder of the number, or the number changed geographic location within the same numbering area, but remained in the same network operator .
