How much does 10DLC (SMS) registration cost?

The fees are carrier pass-through charges, and none of them go to Votel:

Brand registration: a one-time fee of about $4.50 to verify your company.

Campaign (use case): $1.50 a month for Low Volume Mixed, which we recommend, or $10 a month for the standard option. Three months of the campaign are prepaid when you submit.

If your application is denied, each new review is charged.

A phone number costs about $2 a month on top of this. Carrier prices change from time to time, and you see the exact cost on the pricing page before you submit.
