Why does the cheapest VoIP plan so often cost more than it looks?

Summary

Because the low number in the ad is rarely the number you pay. Seat minimums, a second license the plan depends on, features held back for a higher tier, and separate charges for numbers and texting all sit outside it. Rework the price at your own headcount with the features you need, and the order of the "cheap" plans often changes.

A worked example: Teams Phone

Microsoft lists Teams Phone Standard at $10 per user per month, paid yearly. The same card says to "add PSTN service with Teams Calling Plans, Operator Connect or Direct Routing" and that "a separate license for Microsoft Teams is required." On its own, it cannot reach ordinary phone numbers.

What you addMonthly, per user (paid yearly)
Teams Phone with Calling Plan, US (includes Teams Phone Standard)$17
Teams Essentials, if you have no Teams license yet$4
Total$21

The $17 plan comes with 3,000 outbound domestic minutes for the US and is priced with communication taxes and fees included, which is unusual; most providers list taxes and fees as extra.

Minimums and missing features

Aircall sets a minimum of three users on Essentials and Professional, so a two-person office pays for three. Google Voice keeps "call routing with auto attendants and ring groups" on Standard, which is offered only as an add-on to a Google Workspace plan; the Voice-only Starter is for one user in the US. A team that wants a shared main line should price Standard and Workspace together from the start.

Small charges that add up
