The government is moving ahead with linking Aadhaar with mobile SIM cards and all unlinked phones will be deactivated after February 2018, said sources. The sources said Aadhaar mobile linkage was being done as per orders of the Supreme Court passed in February this year in the Lokniti Foundation case.
All SIM cards have to be verified with Aadhaar within a year from the date of judgment, with all unlinked phones to be deactivated after February next year, so criminals, fraudsters, and terrorists cannot use the issued SIMs. The sources said biometrics cannot be stored by the mobile operators nor they have access to any of the other personal data.
They said biometrics collected should be encrypted by the telecom company and sent to UIDAI at that moment itself and any storage of biometric by a service provider is a criminal offense punishable with up to three years of imprisonment under the Aadhaar Act 2016. The government had told the Supreme Court in February that it would put in place, within a year, an effective mechanism for the verification of prepaid mobile users who constitute 90% of the total subscribers. 
Asking the government to put in place the mechanism for the verification of existing prepaid mobile connection holders “as early as possible”, the court disposed of the petition by Lokniti Foundation seeking the scrutiny of the subscribers so that those having prepaid mobile connections on fake identities are weeded out.
