Granite is a national telecom company that puts internet, voice lines, mobile service and network management for many locations on one bill. Its own summary is three short sentences: one bill, one provider, one point of contact.
The thing to understand is how it delivers. Granite brings service to each address over the networks of underlying carriers, and its quoting and trouble-ticket systems are tied directly into theirs. That is how it can offer the right connection at every location instead of only where one network reaches. On top of that it adds what it owns: monitoring, a customer portal, a warehouse operation, and a national team of field technicians. It is based in Quincy, Massachusetts, and serves the United States and Canada.
Best for
- Chains with many locations, such as retail, restaurants and healthcare, that want one provider and one invoice for connectivity, voice and mobile instead of a different carrier in every town.
- Organizations with fire alarms, elevators or payment terminals still running on copper phone lines that carriers are retiring.
- A small IT team responsible for many remote sites that needs someone else to watch the network and send a technician when it breaks.
- Pop-up stores, kiosks, construction sites and rural locations that need a connection faster than new wiring can be run.
- Field workforces and fleets of connected devices that need a SIM able to move between carriers.
- Companies that would sooner hand off the storing, configuring and shipping of network hardware than run that operation themselves.
A single-site business gets less from Granite. The whole design is about pulling many locations and many carriers together.
What they offer
Business Connectivity. Managed Access matches the connection type to each location: dedicated internet, fiber, cable and more. Fixed wireless delivers dedicated internet over a line-of-sight radio link where fiber would take too long. Wireless Broadband uses 4G and 5G as a primary, backup or load-sharing circuit, and Granite resells Starlink for places nothing else reaches. Its Rebill service consolidates the invoices from your other carriers into a single Granite bill with spending reports by location.
Managed and Co-Managed IT. Granite Guardian is tiered network monitoring, from round-the-clock checks with automatic ticketing up to device-level monitoring with an analytics portal. Premium Dispatch adds a trained technician on site with matching replacement hardware. Managed Network Services pairs monitoring with a small appliance called edgeboot that can restart and troubleshoot equipment remotely. Granite 360 is the customer portal for quotes, orders, tickets and dashboards. Managed Warehouse receives, stores, configures, kits and ships your hardware.
SD-WAN and SASE. Design, deployment and ongoing management of SD-WAN on your choice of Meraki, Fortinet or VeloCloud.
Managed Mobility. Device lifecycle management and data plan optimization across carriers, plus a Multi-Carrier SIM and eSIM that roams across more than 600 carriers in over 150 countries.
Voice. Granite EPIK replaces copper phone lines with a device that serves up to 8 analog lines, or 24 with an expansion unit. The company also sells SIP trunking, a cloud phone system, a cloud contact center, and Operator Connect for calling inside Microsoft Teams. See Voice Lines and SIP Trunking.

Proof
These stories come from Granite's own published, anonymized case studies.
A nationwide retailer facing the retirement of its copper and PRI lines. Granite designed a replacement across more than 2,000 locations that combined EPIK, SIP trunking and cloud-hosted voice. The case study reports that project management and rollout planning were completed within 90 days while deployment continued site by site.
A full-service restaurant chain. Its networks came from many providers, circuit installs were missing restaurant opening dates, and an outage could stop card payments. Granite brought the carriers under one relationship, standardized every site on one equipment design, added wireless backup everywhere, and pre-configured the hardware in its warehouse. The reported result was fewer outages and faster openings.
A company managing more than 100 healthcare facilities in the Midwest. It received over 200 telecom invoices a month. Granite consolidated more than 150 of them into one bill, raised bandwidth at over 60 percent of sites, and added edgeboot for redundancy.
For fire and alarm lines, the EPIK datasheet states that the device is permitted under the fire alarm code, NFPA 72, as what that code calls a managed facility-based voice network, and that it is approved for that use by the California State Fire Marshal and the Fire Department of the City of New York.
Good to know
- Much of the installation and repair work is done by Granite's own field technicians, with spare parts staged regionally. The company says most EPIK repairs are handled remotely.
- A Multi-Carrier SIM works only in devices that are carrier-unlocked and on Granite's approved device list, and the company says it makes no exceptions. A trial is available if you supply your own test device.
- Two EPIK datasheets carry the same 2025 date and describe different hardware. Only the third-generation model supports PRI and lists WiFi. Confirm which model your quote covers.
- SIP trunk projects include interoperability testing with your phone system before you sign.
- Granite's scale figures vary between its own documents. One 2022 sheet counts more than 6,000 corporate customers across more than 650,000 locations, and another from the same year says 700,000.

How buying works
The store is the easy part. Staying on the account is the job.
Anyone can show you logos. The reason to buy here is what happens on install night, and on the ticket you open nine months later.
