Comparison
OpenPhone (Quo) pricing vs Signilio for sales teams
Published pricing, what a plan includes, the fees that show up later, and the shared inbox, side by side. Checked September 25, 2026.
The short answer
Quo, formerly OpenPhone, is a business phone system with a very good shared inbox, priced per user with unlimited calling and texting under a fair-use policy. It is not a campaign tool: its own pages say mass texting is not available, group texts stop at ten people, and automated sends cost a cent each. For a small team that texts conversationally from a shared number it is excellent value. For a sales team sending campaigns to a list, it is the wrong category, and the estimator below prices only what it can, the seats.

Common questions
- Is OpenPhone (Quo) cheaper than Signilio?

Note: OpenPhone (Quo) does not offer campaign sending to a list: "Mass texting or bulk texting is not available in Quo"; group texts stop at ten people; larger sends must go out as separate consented messages. Signilio is $189.99 a month on its Pro plan for the same team, carrier fees included. Which one is cheaper changes with volume and team size, so the calculator above gives your own number.
