How do I migrate to a new SMS provider?

Last reviewed 1 min readReviewed by BroadNet engineering
Quick answer

Migrate to a new SMS provider by running the new route in parallel with your current one, re-registering sender IDs in each market, updating API or SMPP credentials and webhook endpoints, testing delivery on real destinations, then shifting traffic gradually while watching delivery receipts. A phased cutover — not a hard switch — protects deliverability and lets you compare cost per delivered message before you fully commit.

The long answer

Everything worth knowing, nothing that isn't.

§01

Re-register sender IDs early

Sender-ID registration has lead times in many markets, so start it before cutover to avoid a gap where messages are dropped. See /answers/how-to-register-sender-id.

§02

Run in parallel and compare

Send a slice of real traffic through the new provider alongside the incumbent and compare delivery rate and operator error codes per country — this is how you verify route quality rather than trusting a coverage map. See /answers/how-to-choose-sms-provider and /answers/sms-deliverability-economics-2026.

§03

Update integrations

Swap API keys or SMPP binds, repoint delivery-receipt and inbound webhooks, and re-test encoding and segmentation before shifting volume. See /answers/what-is-a-messaging-webhook and /answers/how-to-test-sms-integration.

§04

Cut over gradually

Ramp traffic to the new provider in stages while monitoring DLRs, keeping the ability to roll back. A gradual migration turns a risky switch into a measured, reversible move. See /answers/what-is-dlr.
