Hi All,
SMS Contents are not stored by any Mobile Service Provider (MSP), except on the request of an investigative agency. It is similar to phone tapping and would amount to infringement of privacy, if it were to be stored and read by all.
Now comes the question of how long the call detail records (CDRs) are stored and what info they contain.
CDRs are stored upto Seven Years by all MSPs. But they periodically shift all data on tapes and on the server maintain records for anywhere between 6 months to 1 year, this can vary on the operator and pre-paid and post-paid accounts.
The CDRs primarily contain following information:
1. The call originating from the mobile phone (Outgoing call)
2. Call terminating at the mobile phone (Incoming call)
3. SMS originating from the mobile phone (Outgoing SMS)
4. SMS terminating on the mobile phone (Incoming SMS)
5. Start time of Originating or Terminating of the call/ sms
6. Duration of the call
7. Tower ID (Which can be reduced to location within 300 meters roughly) at which the call originated and terminated.
Now comes the question of validity of that SMS as an evidence.
An SMS stored in the Handset is an admissible evidence, but the same need to be proved as per the Indian Evidence Act 65B.
For the same a back-up/ screen shots etc needs to be taken and original handset has to be presented for inspection alongwith an affidavit.
Unless the above conditions are fulfilled, it is a tampered record, which is not admissible.
Hope that clarifies the basic queries regarding SMS as an evidence.
