"IMEI" that is to say International Mobile Equipment Identity, if your handset not having this number then that will stop work since December 1. I think this will affect most of the Chinese made handsets, they only produce these kind of handsets (I don’t know why they were doing so). All mobile operators across India are asked Telecommunication department to stop services to such sets. To check your IMEI number of your set, just Type following code *#06# and get your IMEI number, which will have 15 or 17 digits, authorized by GSMA. If want to know manufacturing date of your handset (I think this code only for nokia sets, if some other set also recognize this code – please inform me ) along with IMEI then try this *#92702689#
Most of the imported low cost handsets are noticed with IMEI number, but duplicate or cloned one. Most of them coming from China, recently many of the Chinese firms are send millions of cheap handsets to Indian market which are invalid as per Indian and international laws.
The IMEI number is currently in AA-BBBBBB-CCCCCC-D format. AA is body identifier, BBBBBB is the remainder of TAC (Type Allocation Code), CCCCCC stands model of the set, D is validates the Id number.
