Switching guide
Tells may be a Twilio alternative for high-volume SMS teams that prioritize hands-on operational support alongside messaging infrastructure. Twilio and Tells differ in product breadth, operating model, support structure, and commercial terms — Twilio sells a global self-serve platform with published support tiers, while Tells attaches an operating team to US and Canada high-volume programs. The right choice depends on countries, channels, volume, internal resources, and service expectations.

The teams that get the most from a move are US/Canada senders at meaningful volume whose bottleneck is operations, not APIs: programs spending engineering time on registration paperwork and carrier-review back-and-forth, teams weighing paid support tiers to get more hands-on help, and organizations running SMS, RCS, voice, and AI conversations across separate vendors. Teams that need broad international coverage, or that genuinely prefer self-serve control with support purchased as needed, are often well served staying on Twilio — the side-by-side comparison covers that honestly.
Your engineers run registration, monitoring, and escalation on the platform’s tooling
The Tells team executes the operational work inside one accountable scope
Monthly and peak volumes; sender types in use (10DLC campaigns, short codes, toll-free); countries; use cases and opt-in flows; current registration status; the channels you want (SMS, MMS, RCS, voice, AI agents); and your integration surface (API, webhooks, platforms). With that, the team can propose a migration plan and commercial terms.
Registration and campaign approval timelines, deliverability outcomes, and carrier filtering outcomes are not any vendor’s to guarantee — Twilio says the same about 10DLC timing on its own pages. Carrier and registry approval decisions remain outside any provider’s sole control. What a provider can own is the quality and accountability of the operational work around those external decisions; that is the part Tells commits to.
Common reasons are operational rather than technical: wanting the provider’s team to run registration and carrier-review work, wanting support included in the relationship rather than purchased as a tier, or consolidating SMS, RCS, voice, AI agents, and number lookups into one accountable scope. Twilio remains a strong platform — as of July 23, 2026 it documents four support tiers and paid professional services — so the question is which operating model fits your team.
For qualifying accounts: 10DLC, short-code, and toll-free registration preparation and submission, carrier-review follow-ups and remediation, routing and deliverability monitoring by sender, route, and segment, opt-out and suppression handling, and escalation — plus implementation help on the API, RCS, AI agents, and call announcements.
It depends on sender types, registration state, volumes, and whether numbers port or new senders are provisioned — which is why Tells scopes it before promising dates. Registration and carrier review timelines involve external parties on any provider.
No provider can honestly guarantee that. Deliverability depends on use case, consent quality, content, sender reputation, and carrier decisions. What Tells commits to is the operational work: monitored sends, investigation of filtering events, and remediation with carriers.
