India may soon ban import of ‘Made in China’ mobile phones that lack the unique IMEI number, which helps authorities track people carrying these devices. Mobiles phones without the International Mobile Equipment Identity (IMEI) number are considered a grave security threat and concerns had been raised over their usage after terrorist attacks, like the one in Mumbai in November last year. IMEI is a 15-digit code which appears on the operator’s network whenever a call is made.
