Kelir vs Quo (formerly OpenPhone)
Same business phone system feature set. Two delivery models — softphone app or real cellular line.
Quo (rebranded from OpenPhone in late 2025) and Kelir ship overlapping business phone system features — auto-attendant, voicemail with transcripts, call recording, two-way SMS, hunt groups (on Quo's higher tiers and Kelir Team). The difference is delivery: Quo runs as a softphone app over Wi-Fi or data, with AI-powered call summaries and shared-inbox SMS as differentiators. Kelir runs the system on a real cellular eSIM line — calls ring on the native dialer, the line works without internet, and 2FA SMS is reliably accepted. Quo wins for desk-bound teams whose workflow lives in the Quo app; Kelir wins for teams whose phones are mobile.

Who should pick which?
You run a sales or customer-support team that lives in HubSpot/Slack, you take most of your calls from a desk on stable Wi-Fi, and shared-inbox SMS workflow + AI call summaries are core to how the team works. Quo is purpose-built for this — Kelir is not.
You're a solo professional or small team, you take work calls on the move (cars, job sites, cafés, in transit), 2FA SMS reliability matters, and you don't want a softphone app between you and a ringing phone. Cellular quality and native dialer behaviour are non-negotiable.
Same business phone system underneath — auto-attendant, voicemail transcripts, recording, hunt groups, IVR. Quo wraps it in an AI-powered shared-workflow app; Kelir wraps it in a real cellular eSIM line. The $9.99/mo delta between Quo Starter and Kelir Solo is the price of swapping softphone delivery for cellular delivery — and getting back native dialer ringing, no-app-required calls, and 2FA SMS that works.
Common questions
Yes, in late 2025. Same product, same team, new brand. The URL is quo.com; openphone.com still redirects. Pricing is unchanged from the OpenPhone era.
Yes. Quo supports port-out, and Kelir supports port-in. Submit through Kelir's port flow with your Quo account number and PIN; expect 2–3 business days end-to-end. Kelir gives you a temporary US number to use during the port window.
On Team Pro, yes — call summaries and transcript search ship as part of the Pro tier. Solo and Team Starter currently include voicemail transcripts but not full-call summaries. Quo's AI feature set is broader and is explicitly the centerpiece of their Business and Scale tiers.
Not on the immediate roadmap. Kelir's model is real cellular numbers per seat — shared-inbox SMS doesn't map cleanly to a cellular line, since the line belongs to a SIM, not to a workflow. Teams that need shared SMS in Kelir use departmental numbers with team-wide forwarding rules in the portal.
Quo Starter is software running on AWS — its marginal cost per user is low. Kelir is a real cellular line with VoLTE interconnect, carrier-grade infrastructure, and per-line costs that don't compress. The $9.99 difference reflects what's underneath: software vs cellular interconnect.
