Cloud Telephony: Why Wi-Fi Is No Longer Enough for Your Field Sales Teams

"Sorry, I can't hear you very well, I'm going through a tunnel..." or "Hold on, let me change rooms, the Wi-Fi isn't picking up well here."

We have all experienced this frustrating situation, either as the caller or the receiver. But for a salesperson in the middle of closing a deal, this isn't just a simple technical annoyance: it is a major risk of losing a sale and damaging the company's brand image.

Do you use a cloud telephony solution for your business but have concerns about your mobile teams?

To guarantee impeccable call quality while on the move, Wi-Fi and 4G/5G are no longer sufficient. Discover in this article how to ensure communication stability for your nomadic teams.

The Limits of "Full Cloud" on the Go: Dead Zones and Unstable Wi-Fi

The majority of current cloud telephony solutions operate exclusively on VoIP (Voice over IP). This means your voice is chopped into small data packets sent via the Internet. While this technology is excellent on a stable network, it becomes the Achilles' heel of the mobile salesperson.

Critical Reliance on Bandwidth

A classic professional mobile app requires a constant, high-quality internet connection. The problem? When traveling, network quality fluctuates constantly. Between switching from one cell tower to another, or the saturation of hotel or train Wi-Fi, data packets get lost. The result: choppy voice, unbearable latency, and dropped calls.

The Challenge of "Dead Zones" and "Grey Areas"

Despite growing territorial coverage, "dead zones" (no data network) and "grey areas" (insufficient speed for voice) remain a reality. For a field salesperson visiting clients in industrial parks or rural areas, relying solely on 4G/5G is a risky bet.

Battery Drain and Notifications

Running a VoIP application in the background consumes a tremendous amount of energy. Furthermore, operating systems (iOS and Android) often "kill" power-hungry apps to preserve battery life, which sometimes prevents the app from ringing during an incoming call.

The Native SIM Revolution: Why Using the GSM Network Secures Your Exchanges

This is where the fundamental difference lies between a classic VoIP app and the Un1ty solution. Where others force traffic through the Internet, we utilize the power of the GSM network via a professional SIM card (or eSIM).

What Is Voice over GSM?

Unlike data, the GSM network (the classic cellular network used for "normal" calls) benefits from absolute priority on cell towers. It is a channel dedicated solely to voice, guaranteeing stability that data can never offer.

The Advantages of Native SIM for Your Salespeople:

• Constant HD Audio Quality: No more choppiness, even with just one bar of signal.
• Zero Battery Drain: Your phone uses its native calling function, which doesn't deplete your battery.
• Simplicity of Use: The salesperson uses their smartphone's native dialer. No need to open a third-party app to make a call.

Understanding the difference between VoIP and GSM is crucial for your infrastructure. We detail these technical components and their impact on your ROI in Chapter 4 of our guide.

Service Continuity: The Secret to Reachability

For a Sales Director, "reachability" is an essential KPI. If a prospect calls back after receiving a quote and hits voicemail because your salesperson's app "crashed" or had no network, you create unnecessary friction in the sales cycle.

Fixed-Mobile Convergence (FMC)

The real challenge of corporate mobility is ensuring the client never knows if the salesperson is at their desk or on the highway. With GSM/Native SIM technology, the professional number is ported directly onto the SIM card.

• Outbound calls display the company landline number.
• Inbound calls ring everywhere, with the reliability of the national mobile network.

Security and Data Control

By using a pro SIM card integrated into your unified communication system, you maintain control. If a salesperson leaves the company, you recover the number and access to the data. Unlike calls made via a personal plan or WhatsApp, every exchange is tracked and synchronized with your CRM (such as Pipedrive or HubSpot), ensuring perfect information continuity.

Why Choose a Hybrid Solution?

The future of telephony isn't about choosing between cloud and mobile, but merging the two. A robust architecture must be able to switch intelligently:

• At the office: Use the power of the softphone on a computer for video calls and CRM.
• On the move: Automatically switch to the GSM network via the SIM for total reliability.

It is this dual approach that definitively eliminates "network stress" for your sales teams. A salesperson who trusts their tools is a salesperson who dares to make more calls, everywhere, all the time.

Reliability, the Foundation of Performance

Investing in a professional mobile app is a good thing, but ensuring it works in the worst conditions is a strategic decision. By replacing "Full VoIP" with a solution using the native GSM network, you offer your teams a work tool that matches their ambitions.
