Which business phone systems have a free trial, and what do you pay once it ends?

Summary

Of the 23 US providers we track, nine print a trial length on their own pages. Seven days: Quo, Grasshopper, Talkroute, Aircall. Ten days: CallHippo. Fourteen days: Dialpad, RingCentral RingEX, JustCall. One month: Microsoft Teams Phone Standard. What you pay afterward is the entry plan each one sells, which on annual billing runs from $10 a user a month (Teams Phone Standard, calling plan not included) to $30 (Aircall Essentials, three seats minimum). Three of the nine say no card is needed to start: Grasshopper, CallHippo and JustCall. Teams Phone takes a card and rolls into a twelve-month paid subscription unless you cancel. Two providers give you thirty days to get your money back instead of a trial (Ooma Office, Phone.com), and five others publish no trial at all.

Providers whose own pages print a trial length, shortest first, and the entry plan you pay for once it ends. Trial terms and the card column read from each provider's pages on October 5, 2026; the price is the plan held in this dataset, checked on the date shown. Where a page says nothing about a card, the cell says so.

What you cannot test during the trial

RingCentral spells out the most. Its trial is for new subscribers only, covers up to 20 phone lines and two devices, and "SMS is not available for trial use." Any trial hardware has to go back within 21 days of cancelling or you are billed for it. A team that texts customers all day cannot rehearse that part before paying.

Teams Phone Standard is the phone system without the phone network. The one-month trial covers the Standard license; calling a regular number needs a Microsoft calling plan, Operator Connect or Direct Routing on top, and the trial does not include one. You can test the dial pad, voicemail and routing between colleagues. You cannot call a customer's cell.

Aircall's paid plans start at three licenses, so a one-person trial is a test of a product you cannot buy at that size.

Quo's page says "Try Quo risk-free for 7 days. Cancel anytime (we'll even remind you)" and nothing about limits. Dialpad's says "14-day free trial with easy self-service setup." Where a page is silent on limits, read that as not stated, not as none.

What happens on the last day

Microsoft is the explicit one: "After your one-month free trial ends, your subscription will automatically convert into a 12-month paid subscription and you'll be charged the applicable subscription fee." A credit card is required to sign up. The trial is a month; the commitment that follows it is a year.

Talkroute: "If you cancel a free trial within 7 days of activating an account you won't be charged a thing (unless you choose to activate paid service before the end of your trial period)." The clock starts when the account is activated, not when you make your first call.

Google Voice has no trial of its own that we could find. It is an add-on to Google Workspace, and the Workspace trial is 14 days for up to 10 users. Google asks you to complete payment setup first and says the payment method will not be charged until the trial ends. Whether Voice can be attached during those 14 days is not something Google's trial pages say.

Grasshopper, CallHippo and JustCall all say no credit card is needed. That also means there is nothing to charge on day eight, eleven or fifteen; the account simply stops.

"Free trial" with no number of days

Three providers advertise a trial without saying how long it lasts. Zoom's trial page lists Zoom Phone "for unlimited domestic calls, SMS messaging, transcription, and more" behind a Start free trial button, with no duration printed. net2phone's plans page has Start Free Trial buttons on each UNITE tier and no length either. 3CX's pricing page has a "Start your free trial" button and, separately, says "Get the 3CX StartUP perpetually FREE for up to 10 users including hosting," which is a free edition rather than a trial; whether that beats paying per seat is its own question. All three may well tell you the trial length at sign-up. We record what is on the public page.

Thirty days to change your mind, instead of a trial

Ooma Office does not run a trial. It has a 30-day money-back guarantee: cancel the account within the window, and hardware bought directly from Ooma is refunded once it is shipped back in its original packaging. Ooma does not refund shipping, and it will not refund hardware bought from a third-party reseller. Ooma says to contact its Customer Care team to cancel, and that charges continue if you do not.

Phone.com prints "30-day money back guarantee" on its pricing page and lists no exclusions there. A guarantee differs from a trial in one way that matters: the money leaves your account first. Budget for the first month and the number, then claim it back.

magicJack for Business is neither. Its $9.99 a line for the first twelve months, renewing at $15.99, is an introductory price, and the page we read lists no trial and no refund window.

The ones that sell by demo or quote

Nextiva's pricing page offers a demo ("No credit card required for demo") and no trial. Vonage Business Communications, Intermedia Unite, 8x8 and GoTo Connect publish no trial either. Intermedia, 8x8 and GoTo Connect route you to sales for a quote, and the last two publish no prices at all, so for them the number comes out of that conversation too.

Testing with your real number

Do not port your business number into a trial. The FCC's guidance on porting is to keep the old service until the new one is working, and a trial that ends on day 14 is not yet a service that works. Test on the temporary number the provider hands you, decide, pay, and port afterward. Can you keep your business phone number when you switch providers? covers the porting rules.

The free plan that is not a trial

CallHippo's Basic plan is $0 for six months and then moves you to Starter. It is the only free-for-a-period plan in this dataset, and the table of what it includes and what Starter costs afterward is in Is there such a thing as a free business phone number?.
