What is a Bulk SMS Reseller?
A bulk SMS reseller is a business that buys SMS sending capacity at wholesale rates from messaging providers and resells it to businesses sending marketing campaigns, notifications, and two-factor authentication codes. The reseller operates a branded SMS platform; the upstream provider handles carrier relationships, A2P compliance, and delivery infrastructure.
How Bulk SMS Reselling Works
The wholesale SMS provider operates connections to mobile carriers worldwide. The reseller gets API access and a branded admin dashboard for managing campaigns, contacts, and billing. Customers send messages through the reseller's branded platform; the upstream provider routes them through carriers and bills the reseller per message.
Common Bulk SMS Use Cases
- Marketing campaigns — Mass-send promotions to subscriber lists
- Appointment reminders — Reduce no-shows with automated SMS
- Two-factor authentication — Send verification codes during login
- Order notifications — Confirm purchases and shipping
- Customer alerts — Service outages, price drops, restocks
Bulk SMS Pricing
Wholesale SMS prices range from $0.003 to $0.05 per message depending on destination country. Retail markups of 30% to 100% are common. Volume discounts increase margins for high-sending customers.
A2P Compliance Requirements
A2P (Application-to-Person) SMS is heavily regulated in many countries. Resellers must register senders, get message templates pre-approved, and comply with opt-in requirements. In the US, this means 10DLC registration; in India, DLT registration; in the UK, opt-in compliance under PECR.
