Goodcall's 'unlimited minutes' has a meter — and it runs on unique callers, not time
Goodcall is the only vendor in this market that bills by how many distinct people call you, so a busy month can quietly double your Starter bill before you notice the cap exists.
“Unlimited minutes” is true on Goodcall, and it’s also a misdirection. The minutes are genuinely uncapped — talk for an hour, talk for ten, the price doesn’t move. What moves is the number of distinct people who reach your line. Goodcall is the only vendor in our dataset that meters on unique customers rather than minutes or calls, and that one design choice is where a busy month gets expensive.
The direct answer
Goodcall’s Starter is $79/mo and includes 100 unique customers. Every additional unique caller that month costs $0.50. So a Starter line that serves 300 unique callers runs:
$79 + (300 − 100) × $0.50 = $179 that month.
That is more than double the sticker price, and you won’t see it coming, because the trigger isn’t call length or call count — it’s how many new faces dialed in. A single busy month (a promotion, a seasonal rush, a viral post) is exactly the kind of event that floods you with first-time callers, which is precisely what the meter counts.
The tier you should have been on
Here’s the part the overage hides: by the time Starter hits 300 callers, you’ve overshot two cheaper outcomes.
| Plan | Monthly | Unique-customer cap | Cost at 300 unique callers |
|---|---|---|---|
| Starter | $79 | 100 | $179 ($79 + 200 × $0.50) |
| Growth | $129 | 250 | $154 ($129 + 50 × $0.50) |
| Scale | $249 | 500 | $249 (flat, well under cap) |
At 300 callers, the Starter plan ($179) costs more than Growth ($154) — a plan that includes 250 callers outright for a flat $129. The crossover is earlier than most buyers realize: Starter’s overage catches up to Growth’s flat $129 at just 200 unique callers, and from there Growth is strictly cheaper. Starter only stays cheaper than the Scale tier ($249 flat) until roughly 440 unique callers — past that, Scale wins.
In other words, the overage meter doesn’t just cost money; it costs the right plan. A Starter buyer who runs hot for one month pays $179 for service that Growth would have delivered for $129 — and Growth would have absorbed the surge without a single overage line.
Why this is unique — and why that matters
Across this dataset, every other flat-rate vendor that advertises uncapped usage caps nothing on the customer side. NextPhone’s Pro and Growth tiers ($199 and $299/mo) are flat unlimited inbound with explicitly “no per-minute fees.” Loman’s Starter and Premium ($199 and $399/mo) state “no per-minute fees, no overage charges” outright. Their bills are volume-independent: a quiet month and a record month cost the same.
Goodcall is the lone exception. Its meter is invisible on a normal month and only fires on your best one — the month a promotion lands, the month word-of-mouth spikes. That’s a defensible model (unique callers are a fair proxy for value delivered), but it inverts the usual reassurance of a flat plan. “Unlimited” here means unlimited time, not unlimited reach.
How to read this
If your caller base is stable and under 100 distinct people a month, Starter at $79 is genuinely flat and genuinely cheap. If it isn’t — if you run campaigns, have seasonality, or simply don’t know your unique-caller count — price the plan at the month you’re hoping for, not the month you’re having now. At 300 unique callers, the honest number is $179 on Starter, or $129 on Growth for the same surge handled cleanly. The lesson isn’t that Goodcall is expensive; it’s that the one vendor billing on unique customers is the one vendor where you have to forecast a number nobody else makes you think about.
