Above mentioned turn-around-time is only approximate and it may vary from time to time for various reasons. SMSHorizon do not have any control on this, however, we will be here to help you through the process.

To speed up approval, consider registering with multiple operators and try submitting different content with different operators.

Note: While creating multiple DLT accounts, your PE ID will remain same and all templates/headers will be synced with each other in realtime. That’s the real advantage of DLT technology.

Now let’s begin with the registration part,

DLT Registration

Choosing operator

Every operator has their own DLT portal and the advantage of this technology is that all operators are in sync with each other and so any changes made on DLT portal will be updated with all others in real-time. 

While you may choose the operator you wish, we would suggest you to go with Jio for now, as the process is simple and easy. Most importantly its FREE (temporarily).

You may also register yourself with multiple operators, if you wish so.

How to Register?

  5. Fill up the form with your KYC details and submit.
  6. You will receive an email with your Entity ID (usually in 5 mins)

Entity ID which is also known as PE ID (Principle Entity ID) is the unique ID for your DLT a/c. This ID will remain the same across multiple operators.

If you have not received the email, don’t worry, login to your DLT account now and you can find your entity ID on the top left in Jio DLT portal.
