Analysis:
There is not much difference between licensed goods and parallel goods. The parallel version and menu text are different. The characters licensed in Hong Kong are traditional, while those licensed in the Mainland are simplified. The operation and stability of the system are the same. Parallel imports can use some functions only by setting relevant parameters themselves.
Regular licensed products and parallel imports can be identified by product packaging, and the mainland version of licensed products is Sony Ericsson W550c；; Parallel imports for cable love W550i；; China Mobile's customized models will also have special marks.
IMEI bar code of the outer packaging box: licensed and tearable (divided into 1.2.3, and pasted with three different mobile phone three-guarantee vouchers respectively); Parallel imports are generally printed directly and cannot be torn.
Check the IMEI (mobile phone serial number): The IMEI displayed on the mobile phone should be consistent with the IMEI on the inside of the mobile phone body and the IMEI on the outer packaging box.
