Looking for a clear, reliable Phone GS review for your business telephony? Here, we sift through customer feedback and real-life usage, without jargon.
We analyze the strengths (Centrex, registrations, worldwide numbers, 24/7 support) and then the potential limitations: reliability, deployment and undisclosed rates.
Objective: to know when it’s relevant… or not, by putting Kavkom’s field expertise into perspective.
Phone GS is a VOIP Centrex telephony service provider targeting mainly small and medium-sized businesses, large corporations and public sector organizations. The offer focuses on ease of use, rapid activation and local numbers worldwide. Positioned more as an established, multi-site company in need of support.
On the product side: basic VoIP functions (inbound/outbound calls, switchboard, transfers, call waiting, voicemail) and useful B2B features, shared recording, pre-hook messaging, callback, PC softphone, call queuing and call automation. A customized open source CRM is mentioned. No AI, omnichannel or analytics bricks are documented. At Kavkom, we find these basics, plus advanced predictive dialer, dashboards and native CRM integrations (Salesforce, HubSpot, Zoho, Pipedrive, Zendesk).
Coverage and quality: Phone GS claims to offer worldwide numbers and unlimited calls to Europe (landlines and mobiles). No public technical indicators. Kavkom provides numbers in 50+ countries and unlimited FR/US/CA rate plans.
Security: Phone GS says it is RGPD-compliant, but does not specify encryption arrangements.
Kavkom applies call encryption and complies with the RGPD.
Support and deployment: Phone GS features a dedicated 24/7 advisor in French. Kavkom also offers French-speaking human support and rapid 100% cloud commissioning.
Rates
If you’re looking for a more modular approach, out-of-the-box CRM integrations and strong contractual flexibility, solutions like Kavkom are clearly worth considering.
In use, Phone GS covers the basics and remains simple to administer. We appreciated the easy handling, call recording with sharing, pre-hook messaging, callback, PC softphone, worldwide numbers and the promise of unlimited European calls. The presence of a 24/7 advisor is reassuring.
Remain cautious: undisclosed rates, few public technical indicators, unspecified encryption, and documented absence of AI, omnichannel or analytics. In comparison, Kavkom publishes its rates, quantifies calls and offers dashboards and CRM integrations.
Here, in a nutshell, is what we liked… and what could go wrong.
✅ Unlimited calls to Europe, landlines and mobiles
✅ Local numbers available worldwide, quick activation
✅ Call recording with archiving and sharing
✅ Pre-hook greeting and callback module
✅ Dedicated 24/7 advisor in French
✅ Basic call center functions: queues, call automator
❌ Unpublished pricing, difficult to budget (Kavkom posts prices from €10 and unlimited from €30)
❌ Few public technical metrics: no SLA, status page or MOS
❌ Undocumented encryption, no certification listed, DPA not available
❌ No AI, no omnichannel, no advanced analytics advertised

❌ Unlimited advertised on Europe only, less flexible than World options on quote
Kavkom removes the grey areas found at Phone GS with public rates starting at €10, a no-commitment, pro-rata offer, native CRM integrations, RGPD-compliant encrypted calls and real-time statistics. You retain control over budget, security and management, while simplifying deployment and day-to-day use.

Imagine you’re managing a field team or a support department, and you’re looking for a simple device for navigation, music and messages on the move. Phone GS seems a credible option, but you want to know what it’s like in real life. We’ve sifted through the reviews available on Google, Trustpilot and Capterra. Here’s what stands out, unfiltered, and what it means in concrete terms for your teams.
The overall impression is divided. On the one hand, many users praise the ease of use, compatibility with popular applications and responsive customer support in French. On the other hand, limitations include dependence on the phone’s connection, and hardware problems such as touchscreen failures.
“The 702B is the ideal size. It doesn’t obscure the TFT info. Customer service is present and very responsive… The main applications are there (Apple music, Waze, phone, message, maps…).”
“Love this equipment, very easy to use and high performance.”
“Touchscreen failed after less than a year despite warranty, laborious support responses.”
Operationally, this means that your teams can rely on a clear, familiar interface, and find essential apps without heavy learning. Quick wins for adoption, especially if the team is heterogeneous or not very technophile. But you need to anticipate the risk of service interruptions without a connected phone, and the time lost in the event of hardware failure. If the device is used for mission-critical tasks in the field, make sure you have a plan B in case of failure.
The returns do not mention details of prices, monthly or annual packages, discounts, installation or termination fees. No useful comments either on the ease of increasing or reducing the number of users, or on potential hidden costs.
In concrete terms, if you plan a gradual or seasonal deployment, you won’t have any user feedback on contractual flexibility. It’s a good idea to ask for a precise costing, examples of fleet evolution, and written conditions for periods of reduced activity.
“Very good support, quick response, product suited to my expectations.”
This feedback doesn’t mention price, but suggests that the product meets simple functional expectations. Without price data in the reviews, it’s impossible to assess the cost-benefit ratio on the user side.
The reviews don’t mention VoIP telephony, call recording or call analytics. The reviews focus mainly on the use of navigation and multimedia applications, and on ease of use.
“The main applications are there (Apple music, Waze, phone, message, maps…).”
Limitations appear on operation without a connected phone. One user reports that no GPS function is available when the smartphone is not connected, and that ordering on a specific model does not work.
“When the phone is not connected, no GPS function is available and the control on my 2017 1200gs does not work with this system.”
In practice, for a manager equipping mobile teams, this means that the system’s autonomy is limited. If the aim is to operate even in the event of a network failure or a discharged smartphone, there may be interruptions in use. For productivity, this is a key point to check upstream with a field test.
None of the opinions mention VoIP security, encryption, multi-factor authentication or SSO. On the other hand, there are weak signals about connectivity dependency, as well as hardware reliability issues.
“When the phone is not connected, no GPS function is available.
As far as pure safety is concerned, nothing can be concluded from the opinions. As far as continuity of service is concerned, the main thing to note is that the telephone link is a possible point of failure. If your teams travel to areas where the network is unstable, make sure you have simple instructions and pre-mission preparation checklists, otherwise you’ll be faced with unforeseen stoppages.
No user feedback on dashboards, exports, APIs or real-time indicators. Reviews don’t describe any reporting tools, or metrics that management can use.
“Love this equipment, very easy to use and high performance.”
In practice, it’s impossible to say whether usable KPIs exist to track adoption, usage rates or incidents. For operations management, this means you’ll have to set up your own tracking system if measurement is an issue.
No reviews mention number coverage, porting, or selection by country and region. The reviews do not deal with telephony as such.
So there’s no basis on which to judge internationalization or a local presence via dedicated numbers. If your strategy depends on multi-country coverage, these reviews won’t help you decide.
On this point, feedback is mixed. Several users praise the responsive support, available in French, capable of helping with configuration and customization. Another mentions slow responses in the event of a hardware failure.
“Customer service present and very responsive… instructions in French and coupling procedure.”
“Very good support, quick response, product suited to my expectations.”
“Touch screen failed… laborious support responses.”
Operationally, you can expect smooth onboarding if your usage is standard. In the event of a hardware incident, processing times may vary. To limit the business impact, it’s best to define a replacement process or buffer stock upstream. Otherwise, an isolated breakdown can immobilize a user for several days and postpone appointments in the field.
The reviews cite compatible applications from the consumer mobile ecosystem, including Apple Music, Waze, Phone, Messages and Maps. There’s no mention of business integrations, CRM or APIs.
“The main applications are there (Apple music, Waze, phone, message, maps…).”
For a sales or support team working with a CRM, the reviews don’t give any indication of native coupling, contact sheet pop-ups or automatic logging. If these integrations are a prerequisite, a technical validation must be planned before any deployment.
By cross-checking the comments, a few concrete lessons emerge for team deployment.
In short, reviews highlight a simple user experience, practical compatibilities and appreciated French-speaking support. Limitations include service continuity without a connected phone, and occasional hardware failures. If your team depends on flawless availability and controllable metrics, these grey areas will need to be addressed during your evaluation.

With Kavkom, I was able to easily resolve the issue of communication costs to my regular customers. My agents, too, were no longer restricted in their mobility, because even when on the move, communications are managed.
