Comms vs Linq for customer messaging
Compare Comms and Linq using real channel eligibility, webhook tests, number lifecycle and a quote for your messaging workload.
Start with the workflow
Reviewed . Current product facts
Choose a provider by whether it supports your application’s actual send, receive and support workflow. Check channel capabilities on the proposed line, supported destinations, authenticated webhook events and delivery-state semantics. Avoid selecting a service solely by bubble color.
Linq’s pricing page lists Pro starting at $260/month and Enterprise by quote (checked 16 October 2026). It does not say how many lines or messages the starting price covers, so ask Linq to quote your line count and workload.

Compare dedicated production lines with dedicated production lines. A shared trial is useful for proving an integration but is not equivalent to an assigned customer number.
| Requirement | Evidence to request from both providers |
|---|---|
| Channels | Capabilities for the actual sender line, recipient and supported country. |
| Replies | Signed webhook payload, retry policy and conversation identifiers. |
| Number lifecycle | Provisioning eligibility, inventory, porting rights and offboarding terms. |
| Operations | Support response, incident history, retention and an SLA if required. |
| Commercial terms | Monthly plan, usage, setup, commitments and migration fees. |
What Comms provides
Comms offers a hosted messaging API, signed inbound webhooks, a team inbox, optional agents and hosted MCP. Free is a shared test line with 100 messages/day. Plus is $50/month on a shared platform line. Dedicated is $200/month with $0 setup; it is a different plan with a dedicated number.
API line claiming requires workspace approval and available inventory. A denied claim returns line_claim_not_allowed; unavailable inventory returns no_available_line.
RCS requires a supported dedicated line, carrier enablement, and a compatible recipient. Sending currently supports one plain-text message to an E.164 phone number.
Porting requires approval and a supported number. Confirm port-in, port-out, geographic availability, fees, and timing before planning a migration. You can cancel replacement setup before submitting the transfer; a submitted transfer cannot be canceled from the setup panel.
AI usage is billed separately from messaging plans, through prepaid Comms credits or a connected customer OpenRouter account. No messaging plan includes AI usage. Review credit-purchase fees and model costs before enabling a hosted agent.
Test each provider
Use a consenting recipient and an eligible test line. Send a message with a stable retry identity, receive a reply, verify the webhook signature, replay an event, and reconcile a delivery receipt. Test explicit channel failures and uncertain sends separately. An accepted request is not a delivered message.
For a SaaS integration, use two tenants and prove that a reply cannot reach the wrong tenant. Check human handoff, opt-outs, credential scopes and line offboarding. Ask each provider for number control, supported countries, throughput and service terms in writing.
Fit with your backend
Comms can be evaluated as a hosted API alongside an inbox and optional agent/MCP workflows. Linq may fit when its current tooling, available channels and commercial terms meet your application’s needs. Confirm those requirements with its current docs and a trial.
Use the same tenant-isolation, reply and retry test rather than assuming that similarly named features behave the same way.
