VoIP calling and WiFi calling are two similar telecom features, but what exactly makes them different from one another?
It’s officially 2025, and all of us at Data Talk want to first and foremost wish your business team a very Happy and Healthy New Year!
It’s understandable if you’re looking to learn more about your business phone system, including popular Web-based mediums like WiFi calling and VoIP calling. These calling features have been used all throughout the world for several years, and there’s still a lot of confusion out there about what makes these two systems different from one another.
So, what exactly is the difference between WiFi calling and VoIP calling? Let’s explore both of them in detail in the below sections!
What Exactly is VoIP Calling?
Voice over Internet Protocol (VoIP) allows business teams to attend calls from any device via a Web connection. This telecom technology essentially converts your voice into data packets, which are then delivered to the call’s other end with crystal clear clarity and quality.
VoIP calling is just one facet of more comprehensive VoIP services, and some of the common advantages of VoIP calling include:
- Cost-Effectiveness: VoIP calls tend to be much more affordable as compared to traditional landlines, and this is particularly the case for international and long-distance calls.
- Flexibility: VoIP calling allows your team to use a wide variety of different devices, including tablets, smartphones and desktops.
- Many Telecom Features: Today’s VoIP solutions include popular features like conference calling, call forwarding, Find Me/Follow Me, call recording, and much more.
- Seamless Scaling: Scaling a VoIP phone system up or down only takes a matter of a few clicks!
- Tech-Savvy Integration: Businesses in 2025 need a lot more than just VoIP technology, and the good news is that VoIP systems can easily be integrated with your other business applications—like your CRM platform.
Some of the disadvantages associated with VoIP calling include:
- Web Dependency: VoIP systems rely on a strong, stable Web connection, which can sometimes lead to issues during internet outages and moments of poor coverage.
- Tech Complexity: VoIP systems are sometimes more complex than they initially seem, which is why the vast majority of businesses are better off hiring expert support like the Data Talk technicians when they need help installing and configuring their VoIP capabilities.
What Exactly is WiFi Calling?
WiFi calling refers to business calls that are made through a WiFi connection, as opposed to your telecom network carrier. WiFi calling has become very popular throughout recent years, and this is partly because it doesn’t require specific applications or physical phone lines.
Most of today’s smartphones are capable of conducting WiFi calls, and it usually only requires a few swipes to activate this built-in feature. Some of the common advantages of WiFi calling include:
- Improved Coverage: WiFi calls often provide improved cell coverage when you’re located within a weak network.
- Great Clarity: WiFi calling typically provides great call quality, especially as compared to traditional landline calling.
- WiFi Integration: WiFi calling can also be easily integrated with other WiFi services and devices.
Some of the common disadvantages of WiFi calling include:
- WiFi Feature Requirement: WiFi calling inevitably requires people to have network availability.
- Compatibility: WiFi calls also aren’t possible unless your device or carrier provides compatibility.
- Limited Telecom Features: WiFi calling isn’t a specialized feature that specifically supports businesses, so it’s typically lacking in comparison to VoIP calling.
- Security Concerns: It’s also possible for WiFi calling on an insecure network to be susceptible to security risks.
The Differences Between VoIP Calling & WiFi Calling
Considering that WiFi is pretty much everywhere and VoIP technology is used by countless businesses, it’s important to understand how these two features differ from one another.
This is why the Data Talk team is always available when you need help acquainting yourself with the many capabilities of these communication channels. Below are a few major differences between VoIP calling and WiFi calling that you should know about:
- Network Reliability: VoIP calling functions independently via the internet, whereas WiFi calling solely works within a mobile device’s network infrastructure.
- Phone Number: VoIP calling will utilize a separate, VoIP-based number, whereas WiFi calling utilizes the phone number that your cell provider gave you.
- Calling Capabilities: VoIP service providers offer far more calling capabilities than cell providers, and WiFi calling will always be held back by a cell carrier’s available features.
- Expenses: VoIP calling is free among your office’s users, and WiFi calling doesn’t include extra charges—except for data usage.
- Security: VoIP calling features end-to-end encryption provided by telecom experts, whereas WiFi calling is safe when connecting to a carrier’s network and unsafe when using public networks.
- Application: Companies often use VoIP calling as a primary phone service, and WiFi calling is best used when you have a weak cellular network.
Choosing The Right Telecom Channel For Your Business
Although it’s safe to say that both calling methods are slightly similar, it’s important to remember that they cater to two distinct market segments.
Here are some factors that business leaders should keep in mind when determining whether VoIP calling or WiFi calling is right for their team:
Calling Nature
One of the most important factors to keep in mind is the basic nature of your company’s daily calling habits.
Since WiFi calling uses existing mobile device numbers and cell service coverage, it’s ideally best for personal calls.
On the other hand, VoIP calling makes both international and long-distance calls easier than ever—all without revealing your employee’s personal cell number. VoIP systems also offer comprehensive call insights and reports, which generally makes it a better option for business communication.
Network Coverage
Your company’s physical location often is a primary factor when choosing between WiFi and VoIP calling. WiFi calling is a valuable feature when your area just so happens to have poor cell service, even if you have an active WiFi connection. This will essentially be your backup connection that’ll help you maintain telecom consistency.
VoIP calling is known for its scalability, which is a huge reason why it’s viable for business phone systems. You’ll be able to receive and make international and long-distance calls at a fraction of the cost of traditional landlines, and you’ll also reap the rewards of countless tech-savvy features and functionalities.
Cost-Effectiveness
WiFi calls might seem affordable at first, until you see your data usage in your next monthly bill. Data consumption via WiFi can be far more costly when compared to VoIP phone system plans that are typically tailored toward businesses with large call volumes.
VoIP providers like Data Talk offer all sorts of pay-as-you-go and flexible plans that make it more cost-effective than ever to get high-quality VoIP calls at affordable rates.
Telecom Features
WiFi calling offers pretty standard features and capabilities like caller ID and voicemail; however, VoIP calling offers a massive amount of features like live monitoring, call recording, IVR, call analytics, call reporting, and so many other features that enrich the business communication experience.
If your company’s communication needs require extensive functionality and monitoring, then there’s absolutely no denying that VoIP services are your go-to telecom option!
