These messages may or may not be triggered by a subscriber-initiated transaction and will not be blocked for subscribers who have otherwise blocked service messages also. These Headers are Case Sensitive...In short these service messages are needed and much necessary information for customers.

    SERVICE EXPLICIT SMS are one kind of unnecessary information to registered clients database or customer so this sms depends entirely upon DLT Operators to be sent to DND clients or not.

    Communication to Principal Entities (PEs) on Consents

    1. Consent Registration

    As per the provisions of TRAI's TCCCPR 2018, all Principal Entities are required to declare and register the consents of their customers on the DLT portal of Telecom Service Providers (TSPs).

    In this regard, we wish to intimate that the bulk consent module on Jio's DLT portal is now live and we advise all PEs to take the following actions on an immediate basis:

  • PEs to register their Consent Templates in the format given on DLT portal.

  • All the consent templates already registered / requested on the portal till date will be considered null & void, if they do not conform to the suggested format.

  • Register all your consent templates on the DLT system. Customers Consent data can be uploaded in the TSPs system.

  • Upload and submit the list of existing subscriber's consent which have been validly acquired by you from the subscribers / customers.

  • Kindly note that the customer consent data can only be uploaded against a duly approved consent template(s).

  • Ensure that the consent data is veracious, valid and acquired as per the due process.

  • In the absence of the customer consent in the TSPs system the PE shall not be able to send consent-based promotional/service explicit messages to their subscribers / customers.

    2. Guidelines for Consent Templates

    All the PEs are required to align their consent templates as per the following guidelines.

  • Registration of the consent template is a pre-requisite for uploading the consents.

  • The Consent Template should not contain any variables.

  • Brand/PE/Trade/Legal Name must be captured clearly in the consent template.

  • The purpose of the consent must also be mentioned explicitly in the consent templates.

  • Below are the Sample Consent Templates for your ready reference. Kindly note that the consent templates not aligned with the above guidelines will not be approved by the TSPs.

  • Sample 1

    [Brand Name]: Dear Customer, thanks for visiting The Design Studio in Andheri (W) today. We would love to stay in touch with you about our new launches and promotions. To continue receiving exciting offers from us on call/SMS.
    please submit your consent [Method of submitting consent to be appended by TSP; Not required from PE].

  • Brand/PE/Trade/Legal Name must be captured clearly in the consent template;

  • The purpose of the consent must also be mentioned explicitly in the consent templates.

    3. Additional security for the consent information

  • The consent data being critical to business, it is imperative that the same is duly protected and secured. However, it has been observed that the consent information whether knowingly or unknowingly and/or directly/indirectly is made available to the third party and hence the same is prone to being compromised or misused. In view of the same, we have introduced an additional security feature. The PEs have the option to secure this information by uploading it from their trusted IP sources and hence we have enabled the IP-whitelisting feature.

  • PEs now have an opportunity of availing this IP whitelisting functionality as a measure towards securing their consent data. We therefore, urge and recommend that PEs should avail this functionality and share their owned IP details (not third party) on the DLT portal of a TSP which shall be whitelisted for uploading the consents.

  • The PEs can provide their IP details on & we shall whitelist it.

    4. What is the process to register Consent Templates ?

  • PEs need to register their consent templates in these formats.

  • Kindly note that the consent templates which are not aligned with the below guidelines will not be approved by the Operators.

  • Register all your consent templates on the DLT portal.

  • The customer consent data can only be uploaded against a duly approved consent template(s).

    5. Are there any guidelines for Consent Templates ?

  • All the PEs are required to align their consent templates as per the following Guidelines:

  • Registration of the consent template is a prerequisite for uploading the consents

  • The Consent Template should not contain any variables.

  • Brand/PE/Trade/Legal Name must be captured clearly in the consent template.

  • The purpose of the consent must also be mentioned explicitly in the consent templates.
