[bbc] India has banned imports of mobile phones which do not have a unique international identification code.
Cheap mobile handsets without the code and imported primarily from China and Taiwan are popular in India.
Over 25 million such handsets are now in use in India, according to the federal telecom ministry.
Last year, Indian intelligence agencies had said phones without the code were being used by terrorist groups in attacks in the country.
