# How do I choose an SMS provider?

> Choose an SMS provider on five measurable criteria: route quality (direct operator agreements versus grey routes), geographic coverage, deliverability transparency (real-time delivery receipts with operator-level error codes), throughput and uptime SLA, and compliance support (sender-ID registration, data residency). Price matters, but the cheapest per-message rate is usually a grey route that costs more per delivered message. BroadNet runs A2P to 200+ countries — direct to the operator in 86, over 1,000+ direct operator connections — at a 99.99% platform SLA — see /operators.

## 1. Route quality is the single biggest factor

A provider either holds direct A2P agreements with operators or resells cheaper grey routes that impersonate P2P traffic. Direct routes preserve your sender ID, deliver predictably, and return real operator error codes; grey routes are blocked by SMS firewalls in hours-to-days. Ask any shortlisted provider, in writing, whether the route to each of your priority countries is direct. See /answers/what-is-grey-route-sms.

## 2. Deliverability transparency

You cannot manage what you cannot see. A serious provider returns per-message delivery receipts (DLRs) with operator-specific error codes, not generic UNKNOWN failures — so you can diagnose why a message failed and to which network. See /answers/what-is-dlr and the /tools/smpp-error-codes lookup.

## 3. Coverage, throughput and SLA

Match the provider's footprint to your destinations, confirm sustained throughput (TPS) for OTP-class bursts, and get the uptime SLA in the contract. BroadNet sustains up to 30,000 SMS/sec per node and publishes a 99.99% platform SLA. See /answers/what-is-tps and /answers/what-is-throughput-sla.

## 4. Compliance and regional support

In regulated markets you must pre-register alphanumeric sender IDs and, increasingly, honour data-residency rules. A provider with local regulatory knowledge and operator relationships shortens go-live. See /answers/how-to-register-sender-id and /regulations.

## 5. Total cost of a delivered message

Compare cost-per-delivered-message, not the headline per-message rate. Grey routes look cheap until you add re-sends, sender-ID degradation, and the customer-experience cost of failed OTPs. See /answers/how-to-reduce-sms-costs.
