Six stories up, a rebar crew stands idle waiting on a pour that was supposed to start twenty minutes ago. The superintendent has the batch plant on hold. The gate foreman is texting a crane operator who cannot take his eyes off the load. Somewhere in the gap between those two conversations, half a day of schedule quietly evaporates.
That gap costs more this year than it used to. Construction input prices climbed 4.8% year over year in March 2026, the steepest annual jump since January 2023, while 82% of contractors report difficulty filling hourly craft positions. Thinner crews and pricier materials mean every idle hour lands harder on the bottom line.
Push to talk over cellular has become the standard fix, trading repeaters and line-of-sight limits for instant voice that reaches every crew on every site through one channel.
This guide covers seven providers contractors are weighing in 2026: what each costs, which devices it runs on, how it handles dead zones and documentation, and which type of operation it suits.
A side-by-side comparison comes first, then a closer look at each option, followed by the criteria worth applying before any contract gets signed.
Push to Talk Providers Compared: Price, Hardware, and Jobsite Fit
The push to talk over cellular market is projected to reach $8.21 billion in 2026 and climb to $16.65 billion by 2034, with construction named among the verticals driving that demand. Below is how the seven stack up on the terms contractors ask about first.
| Provider | Best fit | Service cost | Hardware | Jobsite standout |
| Peak PTT | Crews wanting dedicated radios without contracts | $24.95/radio/mo, flat | Rugged LTE handhelds, $129–$389 one-time | Ships pre-programmed; GPS every 60 seconds |
| T-Mobile | Firms already buying T-Mobile business lines | From ~$20/line on CoreMobile | BYOD smartphones, rugged handsets | Five-year price guarantee on talk, text, 5G |
| AT&T | Contractors on public infrastructure work | EPTT bolt-on from ~$3–$5/line | Smartphones, feature phones, radio gateways | Land Mobile Radio interoperability |
| Voxer | Small GCs and subs piloting PTT | Free tier; Business $6/user/mo yearly | Any iOS or Android phone | Live plus recorded voice with transcripts |
| Microsoft | Companies standardized on Microsoft 365 | Included with frontline licenses | Phones and Teams-certified headsets | Talk groups map to existing project channels |
| Motorola | Mixed licensed-radio and broadband fleets | Quote-based; add-ons from ~$8/user/mo | TLK 25, 100, 110, 150 devices | Bridges MOTOTRBO radios to LTE users |
| RingCentral | Offices already running RingEX | $5/user/mo atop a $20+ RingEX seat | Desktop and mobile apps | One vendor for phones, chat, and PTT |
Three camps emerge: dedicated radio programs, carrier-attached services, and software layers riding on platforms you already fund.
1. Peak PTT

Peak PTT is a push-to-talk over cellular provider since 2018. They operate from Valencia, California. Their model is deliberately simple: buy the radio once, pay one flat monthly rate, skip the carrier contract, and hand crews a purpose-built device.
Flat pricing, zero contract
Service is $24.95 per radio per month, unlimited and nationwide, with no term commitment. Hardware is a one-time buy: the compact PTT-284G at $129, the rugged PTT-84G at $229, the PTT-M14G in-vehicle mobile at $249, the PTT-324G at $259, and the touchscreen PTT-624G at $389.
Built for dust, drops, and gloves
Rugged models carry IP67 dust and water ratings plus military-spec drop testing. Latency stays under 300 milliseconds on LTE, transmissions are encrypted, and GPS reports every 60 seconds with geofencing and route history.
Why contractors pick it
Radios ship pre-programmed with your talk groups and land in roughly two business days, with channel changes pushed over the air free. A lifetime hardware warranty holds while service stays active, backed by a 45-day money-back guarantee.
2. T-Mobile
T-Mobile for Business sells push to talk as an app-based service layered onto standard business lines, with construction among its named target verticals. Contractors already issuing phones to supers add PTT as a checkbox on an existing account rather than a fresh procurement cycle.
What the lines cost
CoreMobile pricing has run near $20 per line under 2026 promotional terms, with activation credits offered per new line. A five-year price guarantee applies to monthly talk, text, and 5G data, though a class action filed in 2025 challenging how that guarantee is interpreted remained active through 2026, so get written terms.
Network reach
Ookla ranked T-Mobile the best mobile network in the US on second-half 2025 testing. Its mid-band 5G footprint covers roughly 300 million people at typical speeds of 300 to 500 Mbps.
Best fit and tradeoffs
Strongest for contractors already issuing smartphones to project managers and supers who want one consolidated bill. Rural coverage remains the weak point, which matters on highway, solar, and pipeline work far from a tower.
3. AT&T
AT&T Enhanced Push-to-Talk comes in Standard and Advanced tiers, both running over LTE and Wi-Fi. The carrier built it as a migration path for organizations sitting on aging licensed radio systems, which describes a large share of heavy civil and utility contractors.
Pricing structure
Bolt-on plans through FirstNet have listed around $3 to $5 per line, with PTT-only feature phone plans ranging from roughly $10 to $22 depending on device subsidies and the purchasing contract used.
Bridging your existing radios
The Advanced tier adds Land Mobile Radio interoperability, letting a smartphone user drop into a talkgroup with a licensed radio fleet instead of replacing it. FirstNet priority and preemption also comes into play on DOT, utility, and disaster recovery work where a site shares congested spectrum with responders.
Best fit and tradeoffs
Built for contractors on public infrastructure programs. Tiered licensing, approved-device lists, and procurement paperwork stretch timelines well past a plug-and-play radio order, so budget weeks between purchase order and first transmission.
4. Voxer
Voxer runs on phones crews already carry, with no hardware to buy and no dedicated device to charge overnight. That makes it the cheapest way to learn whether your team will use push to talk at all before committing any capital.
Free tier through business plans
The free version delivers live and recorded voice with 30-day message storage. Voxer Pro sits at $7.99 monthly or $59.99 annually. Voxer Business runs $6 per user per month billed yearly and adds unlimited storage, admin-controlled chats, voice-to-text transcription, message recall, and end-to-end encrypted private chats.
Live and recorded in one thread
The hybrid model suits construction well. A super talks live to the pour crew while leaving a message for a plumber working under a slab with no signal. Transcripts double as a searchable record for daily reports and delay claims.
Best fit and tradeoffs
Ideal for small GCs and subs testing the concept cheaply. No rugged device, no hardware button, and every other phone notification competes for attention on a screen coated in concrete dust.
5. Microsoft (push-to-talk app)
Walkie Talkie in Microsoft Teams ships with Microsoft 365 frontline licenses rather than as a standalone product. Microsoft aimed it squarely at frontline staff who need quick group voice without opening a call, a description that fits a framing crew reasonably well.
Cost sits inside your license
Firms already paying for Teams add push to talk at no extra software cost, which changes the calculation for any GC running a Microsoft-standard stack across estimating, scheduling, and document control.
Talk groups you already built
Press-and-hold transmissions broadcast to a Teams channel, so talk groups inherit the structure a project team uses daily: one per trade, one per building, one per phase. Administration flows through the Teams admin center and frontline hub, where IT provisions new sites and applies policies alongside Shifts and Tasks.
Best fit and tradeoffs
Suited to contractors with real IT support. Deployments stumble most often on licensing prerequisites and device compatibility, and no purpose-built rugged handset exists around the feature.
6. Motorola (WAVE PTX)
Motorola Solutions sells broadband push to talk as WAVE PTX, a carrier-independent subscription running over LTE and Wi-Fi. The company spent decades supplying licensed two-way radios to jobsites, and the platform reflects that history in both its hardware lineup and its dealer channel.
Devices and licensing
Purpose-built hardware includes the TLK 100 and 110 handhelds, the TLK 150 in-vehicle mobile radio, and the TLK 25 Wi-Fi wearable. Add-on licenses such as Wi-Fi backup list near $8 per user monthly, with core seat pricing quoted through dealers.
Where it separates from the pack
Bridging is the differentiator. A contractor with a MOTOTRBO fleet can put the crane operator on a repeater channel and the PM on a smartphone inside one talkgroup. Location-based temporary talkgroups add and drop members as they cross a geofence, useful on phased sites.
Best fit and tradeoffs
Right for mixed fleets protecting an existing radio investment. Dealer-mediated purchasing and quote-only pricing slow the process, and per-user costs typically land above flat-rate competitors.
7. RingCentral
RingCentral offers push to talk as a $5 per user monthly add-on license layered on a RingEX seat. It arrives as a feature inside a business phone system rather than a communications tool designed for anyone standing in mud on a deck.
Doing the arithmetic
RingEX starts at $20 per user monthly on annual billing for Core, $25 for Advanced, and $35 for Ultra. Effective cost per field user therefore lands between $25 and $40 monthly once the base seat is counted, well above dedicated radio service.
The consolidation argument
A contractor already running estimating, accounts payable, and dispatch on RingEX extends PTT to field supervisors without a second vendor, a second contract, or a second app competing for space on the phone.
Best fit and tradeoffs
Sensible for office-heavy operations. The add-on structure stacks quickly across SMS boosters and AI tools, and with no rugged hardware or physical button it suits supervisors, estimators, and PMs rather than crews swinging hammers on a deck.
Matching the Provider to How Your Crews Work
Labor pressure changes the math. Associated Builders and Contractors projects the industry needs roughly 349,000 net new workers in 2026 and another 456,000 in 2027, while AGC found 45% of contractors had at least one project delayed by workforce shortages. When one superintendent covers three sites, coordination speed becomes a schedule input rather than a convenience.
Weigh these before signing: coverage across every active site including basements, parking structures, and steel decks; whether crews need a gloved-hand button or can work a touchscreen; battery life across a ten-hour shift; recording and transcription for documentation; GPS and geofencing tied to your equipment accountability and protecting site assets program; and whether you already own licensed radios worth bridging. Total monthly cost per field user, hardware amortization included, tells more than any advertised per-line rate. Communication tools sit alongside construction safety methods and AI surveillance as part of one operational picture.
Making the Call Before Your Next Mobilization
The seven options divide cleanly. If crews wear gloves, drop things, and work where a phone screen fails, dedicated radio programs from Peak PTT or Motorola earn their keep. If your field staff already carry smartphones on a carrier plan, T-Mobile or AT&T folds PTT into an existing relationship. If coordination happens mostly among supers, PMs, and the trailer, Voxer, Teams, or RingCentral ride on software you fund anyway.
Test before you scale. Run a pilot on one active site through a full phase, checking transmission quality in the elevator shaft, the below-grade parking level, and the far corner of the laydown yard. Peak PTT’s 45-day guarantee and the trial windows offered elsewhere make that verification nearly free. The channel your crews keep reaching for is the one worth buying.
