The cheapest plans cover calls and voicemail, and they usually drop recording and CRM tools.
Cheap is the right pick when you only need calls and voicemail.
Recording, analytics, and CRM links usually sit on a higher tier.

The cheapest plans cover calls and voicemail and little else. They usually drop call recording, analytics, and integration with your CRM. Cheap is the right answer when you genuinely do not need those, and an expensive mistake when you do.
Entry tiers are the cheapest, and the savings come from what they leave out. Check whether texting, recording, and extra numbers cost more on top. A cheap base plan with three add-ons is not cheap.
There are free apps that give you a second number. They are not business phone systems: no main number routing, no shared voicemail, and no support when a call fails. They suit a sole trader, not a team.
Usually call recording, reporting, CRM integration, and priority support. Some entry plans also cap texts or exclude them entirely. Read what the tier above includes, because that gap is what you are saving.
Compare the all-in monthly total for the same number of seats and the same term. A sticker price with fees excluded is not comparable to one with fees included. Normalize both before you decide.
