Are you using a Unbranded Chinese mobile without having IMEI (International Mobile Equipment Identity)? You can’t use that kind of mobile phones after this April. All mobile phone service users have been directed by the Department of Telecom (DoT) to disconnect these phones. The telecom companies will disable connections that use Chinese mobile handsets. The mobile phone companies have undertaken to acquire the necessary equipment to track these phones by April 15 and discontinue their services thereafter – a process that is expected to take another 15 days, that is, by April 30.
