Zonitel vs Quo (formerly OpenPhone)
A Full Phone System, Not Just an App
Short answer
Quo (formerly OpenPhone) is an app-based phone service from $15 per user on annual billing ($19 monthly), with an AI agent that can answer calls. Zonitel is a full business phone system at $30, $25, or $20 per extension month-to-month, with an auto attendant on every plan, desk phones, digital fax, WhatsApp, and English/Spanish support.
OpenPhone rebranded to Quo in September 2025. It is popular with solo founders and small teams that want calling and texting in an app. Zonitel adds the pieces a growing office usually needs — phone menus, desk phones, fax, and WhatsApp — with month-to-month billing. Facts about Quo come from Quo's own pricing and support pages, checked on October 7, 2026.

When Quo May Be the Better Fit
Every business is different. These are cases where we'd tell a friend to look closely at the other option.
You're a solo founder on a tight budget
Quo Starter is $15 per user on annual billing — less than Zonitel's $30 tier for 1–5 extensions.
You want an AI agent to answer calls
Quo's Sona agent answers live calls (10 calls a month included, then $1 per call or a monthly tier). Zonitel's AI answers texts and analyzes calls, not live calls.
You only need an app
If your team never uses desk phones, fax, or phone menus, Quo's app-first approach can be simpler.
You send lots of picture messages
Quo includes MMS in its texting. Zonitel bills MMS separately.
