Energy work happens in places phones can’t reach and radios sometimes give up. From offshore rigs to wind farms in remote spots, crews need a way to talk that just works. Push-to-Talk over Cellular (PoC) can deliver that.
The global PoC market hit $7.50 billion in 2025 and is projected to climb to $16.65 billion by 2034, with energy and utilities ranking among the fastest-growing segments.
Below you’ll find five PoC tools for energy companies worth a look in 2026.
We’ll open with a side-by-side comparison, then go deeper on each one.
How These 5 PoC Solutions Compare
Each tool below brings something different to the table. Some lean into rugged hardware, some into mission-critical software, and some keep things light for smaller crews. Use this as a starting point, then dig into the details below.
| Solution | Best For | Devices | Standout Feature |
| Peak PTT | Field crews of all sizes | Rugged radios + apps | 99.999% mission-critical uptime SLA |
| Microsoft Teams | Crews already on Microsoft 365 | Any iOS/Android phone | Free with paid Teams license |

The table is a quick scan, so don’t sweat the details just yet. Each option below digs into what the tool does, the standout features, and what it can cost you. If a row catches your eye, jump straight to that section.
1. Peak PTT
Peak PTT builds rugged PoC radios and runs three software platforms (K2, PeakLink, and Everest) on multi-carrier 4G LTE. The Everest tier carries a 99.999% uptime SLA with one-second PTT call latency, AES-256 encryption, and high-availability redundant servers. If you run oil, gas, solar, wind, or nuclear sites, Peak can match the platform to your risk level.
Key Features
- 999% mission-critical uptime SLA on Everest tier
- 60-second GPS tracking and breadcrumb history
- AES-256 encryption for voice and data
- SOS alerts, lone-worker, and man-down features
- Rugged IP54-rated handsets that ship same day
- 24/7 U.S.-based human technical support
What is the cost for Peak PTT?
Peak’s PTT-284G handset comes in at $129 with no contract required. Service plans run on a fixed monthly per-device fee, and lease bundles can roll devices and airtime into a single monthly payment if you’d rather skip the upfront hardware cost.
2. Microsoft Teams (Walkie Talkie)
Microsoft Teams Walkie Talkie turns Android and iOS phones into PTT radios, riding on the same Teams channels your office already uses. It runs over Wi-Fi or cellular data, with no extra licenses for paid Microsoft 365 and Office 365 subscriptions. Energy crews already on Teams can fold in field comms without buying new tools.
Key Features
- Built into the Teams app on iOS and Android
- Connects through your existing Teams channels
- Works with wired and Bluetooth PTT-button headsets
- Encrypted voice over Wi-Fi or cellular data
- Managed from the Microsoft Teams admin center
What is the cost for Microsoft Teams Walkie Talkie?
Microsoft Teams Walkie Talkie comes free with most paid Microsoft 365 and Office 365 subscriptions. If your energy company already runs Teams, the PTT layer can cost nothing extra. Per-user Teams pricing varies by plan tier, so check what your existing license already covers before paying for another tool.
3. AT&T Enhanced Push-to-Talk (EPTT)
AT&T EPTT runs sub-second PTT calls over 4G, 5G, and Wi-Fi, with two tiers (Standard and Advanced). The Advanced tier adds 3GPP Mission Critical PTT features like emergency calling and LMR interoperability. Energy companies on FirstNet can layer priority and preemption on top, which can matter during storms or grid events.
Key Features
- One-to-one and group calls up to 250 users
- 96 talkgroup channels in LMR-style interface
- Encrypted multimedia messaging (text, photos, video, files)
- Web-based Corporate Admin Tool and dispatch console
- Geo-fencing and live location sharing
- Works on rugged handsets, smartphones, and PTT-only devices
What is the cost for AT&T EPTT?
EPTT is sold through AT&T Business with monthly per-device pricing that varies by tier and contract. EPTT-only plans (no voice or data browsing) are available on select devices, while Advanced rolls in priority services and LMR interoperability charges. Quotes come direct from AT&T sales reps.
4. Motorola WAVE PTX
WAVE PTX is Motorola’s nationwide PoC subscription service, working across smartphones, TLK rugged radios, and MOTOTRBO LMR systems. The SafeGuard add-on layers in 3GPP MCPTT features like emergency calling and ambient listening. If your energy team already runs Motorola radios, WAVE can bridge old and new on one network.
Key Features
- Carrier-independent broadband PTT subscription
- Multimedia sharing (text, photos, video, file attachments)
- Talkgroup scanning with priority preemption
- Geofence-based temporary talkgroups (SafeGuard)
- Ambient and discreet listening for dispatchers and supervisors
- LMR interoperability with MOTOTRBO and other radio types
What is the cost for Motorola WAVE PTX?
WAVE PTX runs on per-user monthly subscriptions with no capital expense and no long-term commitments. The SafeGuard package can run around $8 per user per month on top of the base service. Pricing varies by reseller and bundle, and TLK radio hardware adds an upfront device cost on top.
5. Verizon Push to Talk Plus
Verizon Push to Talk Plus runs on Verizon’s nationwide 4G LTE network, with approximately one-second call setup and Wi-Fi failover. It calls out energy as a target vertical, supports up to 3,000 users with the Advanced Group add-on, and bridges to land mobile radios for crews still on legacy systems.
Key Features
- Sub-1-second call setup over 4G LTE or Wi-Fi
- Group calls up to 3,000 with Advanced add-on
- Discreet Listening and User Check via Group Command
- Windows-based dispatch console for control rooms
What is the cost for Verizon Push to Talk Plus?
Verizon PTT Plus pricing starts around $30 per line, according to public listings. Add-on bundles like Group Advanced and Group Command bump that up. Rugged hardware (Kyocera DuraForce PRO, Samsung rugged phones) is sold on top, often with multi-year service commitments to lower upfront device cost.
Picking the Right PoC Tool for Your Field
PoC tools have come a long way, and energy companies now have plenty of solid picks to choose from. Peak PTT can deliver a full hardware-and-software package with carrier-grade uptime. Microsoft Teams Walkie Talkie keeps things software-light if your crews already carry phones.
AT&T EPTT, WAVE PTX, and Verizon PTT Plus lean on big carrier networks and LMR bridging. Match the choice to your sites, your safety risks, and your budget. If your crews work in remote spots and downtime can cost lives or millions, the right PoC tool can pay for itself fast.
