What is Wholesale SMS Termination?
Dollu's wholesale SMS termination service gives aggregators, carriers, MVNOs and OTT platforms a single hub into more than 800 mobile operator connections in 220+ countries. You bind to our SMSC cluster over SMPP 3.4, submit traffic with your own sender IDs and message classes, and we terminate each message on the direct, premium or wholesale route that matches the quality tier you selected for that destination - returning operator delivery receipts and full per-message accounting.
Our route portfolio is built on direct SMPP interconnects with mobile network operators, supplemented by a small number of vetted premium hubs for coverage in markets where direct binds are not commercially available. We do not resell grey routes, and every supplier is tested continuously with live handsets so that the DLRs we return to you reflect real terminal delivery. Routes are classified as Direct (operator bind, sender ID intact, real DLR), Premium (single-hop hub, sender ID intact) or Wholesale (cost-optimised, sender ID may be replaced), and you choose the tier per destination.
Rate decks are published per country and per operator, updated with a minimum of seven days' notice on increases and available in the portal, by scheduled email and through the API in standard formats. Capacity is provisioned per bind cluster with committed TPS and burst headroom, and our NOC watches every route for delivery-rate, latency and DLR-conformance drift around the clock, moving traffic before your customers notice.
For mobile operators we offer the other side of the relationship: managed A2P termination into your network with firewall enforcement, contracted enterprise traffic and transparent revenue share, so international A2P becomes a monetised, protected product line rather than an uncontrolled cost. Our carrier-relations team is available at [email protected] to discuss bilateral traffic exchange, hubbing arrangements or a full monetisation partnership backed by our SMS firewall.
A2P SMS path: from your application to the handset.
Why choose Dollu for wholesale sms.
The advantages of buying from a carrier that owns its network, interconnects and operations - rather than a reseller.
Coverage without 800 contracts
One agreement and one bind cluster reach the operators that would otherwise take years of bilateral negotiation, with new direct connections added every quarter.
DLRs you can trust
Every route is verified with live handsets so the delivery receipts we pass back are real terminal DLRs, not fake or hub-generated acknowledgements - critical when your customers bill on delivered messages.
Transparent, competitive economics
Per-operator pricing, volume tiers and no hidden surcharges; rate changes are notified in advance and available by API so your own rating engine stays in sync.
Capacity for real peaks
Multi-tenant SMSC clusters in Europe, the US and Asia with thousands of messages per second per customer and horizontal headroom for OTP bursts and campaign spikes.
Monetisation for operators
MNOs and MVNOs gain a managed A2P termination channel with firewall enforcement and revenue share, turning grey traffic into contracted revenue.

Direct, premium or grey.
Where an SMS route class shows up: in delivery, in the sender ID your customer sees, in the truthfulness of the delivery receipt and in the compliance risk you carry.
| Dimension | Direct operator | Premium aggregated | Grey routesNot offered by Dollu |
|---|---|---|---|
| Delivery | Direct SMPP bind to the mobile operator; the highest and most consistent delivery | Via a vetted hub or Tier-1 aggregator holding operator agreements; high delivery with occasional re-routing | Via SIM farms or unauthorised international paths; unpredictable, filtered and blocked without notice |
| Sender ID | Registered alphanumeric ID, short code or long number preserved exactly | Registered sender ID normally preserved; may be substituted on a few destinations | Overwritten with a random numeric sender; your brand is invisible |
| DLR quality | Handset delivery receipts from the operator | Operator or hub receipts; reliable, occasionally delayed | Fake or aggregator-generated receipts; no proof of delivery |
| Compliance risk | Lowest - operator-approved, with DLT, 10DLC or sender-ID registration completed up front | Low - operator agreements in place; Dollu vets every hub it uses | High - breaches operator terms and local law; carries fines, blacklisting and lost sender IDs |
| Price position | Highest per message; the lowest cost per delivered, verified message | Mid | Lowest headline price; the hidden cost is failed OTPs, blocked traffic and brand damage |
Dollu does not sell grey routes. Every destination on our deck is direct operator or premium aggregated, and the route class is shown against each price so you know exactly what you are buying.
