Is your mobile phone Kosher or Jekyll?
Press *#06# and the international mobile equipment identity number appears.
Then check the 7th and 8th numbers:
IF the SEVENTH & EIGHTH digits are 02 or 20, this means your phone was assembled in the Emirates and is bad quality
Seventh & Eighth digits 08 or 80? Your phone was manufactured in Germany, which is OK quality
Seventh & Eighth digits 01 or 10? Your phone was manufactured in Finland, which is very good
Seventh & Eighth digits are 00: your phone was manufactured at the original factory and is the best quality
Seventh & Eighth digits are 13 - this means your phone was assembled in Azerbaijan, which is very bad quality and possibly dangerous.
Mine's 02 - Emirates.
