Vias Groups is an India-based bulk SMS service for users and resellers. Resellers can create their own SMS gateway, brand their portal as they like, pick their own SMS prices, and claim themselves as the developers. Resellers can even subsequently offer their services to other resellers. Users can create and manage multiple sub-accounts and allot credits, validity, etc. to those accounts. Accounts can be integrated with third-party applications programmatically via API.
