Pay Per Line, Not Per Person
coreSimtex plans are charged per simultaneous call path, not per user. Size your plan to your actual call volume, not your headcount.
Most Teams calling providers charge a licence fee for every user in your organisation — whether they make five calls a day or five calls a month. That adds up fast. A 50-person office paying $15–$25 per user is spending up to $15,000 a year on calling, even though only a handful of people are on the phone at any given moment.
Simtex plans are charged per simultaneous call path instead. You buy the number of concurrent lines your business actually needs, and every Teams user in your tenant can make and receive calls through them. Fewer lines to pay for, the same coverage for your whole team.
No Lock-In Contracts
Month-to-month flexibility with no minimum terms. Scale up or down as your business needs change — cancel anytime.
