What is VoLTE calls? Advantages, disadvantages & functions at a glance
The way we make mobile calls has evolved significantly in recent years. One of the most important developments in this area is VoLTE (Voice over LTE). But what exactly does it mean, and what are the advantages and disadvantages of this new communication technology? In this article, you’ll learn everything you need to know about VoLTE calls, how they work, which devices support them, and whether you should activate them. Especially in times when stable phone connections are essential, VoLTE plays an increasingly important role. But is it really worth activating VoLTE, or are there potential drawbacks? Here, you’ll find all the relevant information.
Many people are unaware of which network technologies are used for making calls and how Voice over LTE differs from traditional calling methods. Yet, this new standard offers many benefits that can greatly improve your daily life. Whether you frequently travel or handle business calls, the improved call quality can make a significant difference. Even for casual use, VoLTE is interesting because you can continue browsing the internet without interruptions while making a call.
What Are VoLTE Calls? Everything You Need to Know
VoLTE stands for Voice over LTE and refers to the ability to make voice calls over the LTE network instead of the traditional 2G or 3G networks. This technology promises better call quality, faster call setup, and simultaneous use of voice calling and mobile internet.
VoLTE Calls Meaning: A Simple Technical Explanation
Previously, phone calls were transmitted using the “circuit-switched fallback” method, where the mobile network switched back to 2G or 3G for voice calls. With Voice over LTE, however, your smartphone remains on LTE, allowing for the highest quality calls.
How VoLTE Calls Work: A Behind-the-Scenes Look
VoLTE uses IP-based telephony (VoIP), meaning calls are transmitted over the internet, similar to messaging services like WhatsApp or Skype.
The Difference Between VoLTE Calls and Traditional Calls
| Feature | VoLTE | Traditional Telephony |
|---|---|---|
| Network Type | LTE | 2G/3G |
| Call Quality | High (HD-Voice) | Lower |
| Call Setup Time | Fast | Slow |
| Simultaneous Internet Use | Yes | No |
Which Networks Support VoLTE Calls?
Not all mobile providers support VoLTE nationwide. While o2 was an early adopter of this future technology in Germany, many Swiss providers are still lagging behind. Smaller providers often do not include VoLTE in their plans.
Should You Activate VoLTE Calls? What You Should Know
If your mobile plan and smartphone support VoLTE, you can activate the function in your settings.
Requirements for Using VoLTE Calls
- A VoLTE-compatible smartphone
- A compatible mobile plan
- A SIM card that supports VoLTE
- Activation of VoLTE in your phone settings
When Should You Disable VoLTE Calls?
There are situations where disabling VoLTE can be beneficial. For example, in poorly developed LTE networks, VoLTE may cause issues. Additionally, LTE calls can drain battery life more quickly.
VoLTE Calls vs. Wi-Fi Calls: Which Is Better?
If you are in an area with poor LTE reception, making calls over Wi-Fi can be a good alternative.
Advantages of VoLTE Calls: Why It’s Worth Using
VoLTE technology offers numerous benefits:
- Faster call setup
- Best voice quality
- Simultaneous internet browsing during calls
- Better network coverage in LTE areas
Faster Call Setup
VoLTE enables significantly faster call setup than traditional calls. While a standard call can take several seconds to connect, VoLTE calls are almost instantaneous. This means less waiting time and an immediate connection—especially useful in business or urgent situations.
Best Voice Quality
By using HD-Voice, VoLTE offers much better voice quality compared to older network standards. Voices sound clearer, more natural, and have fewer background noises. This is particularly beneficial in noisy environments or for business calls.
Simultaneous Internet Browsing While Calling
Unlike traditional 2G or 3G calls, where internet access is interrupted during a call, VoLTE keeps the LTE connection active. This is particularly useful if you need to look up an address, check an email, or use an app while talking on the phone.
Better Network Coverage in LTE Areas
In many regions, LTE coverage is better than older 2G and 3G networks. With VoLTE, you can maintain a reliable phone connection even in these areas, making it especially useful in rural regions or inside buildings where LTE signals are often stronger.
Disadvantages of VoLTE Calls: Are There Any Downsides?
While VoLTE has many benefits, there are also some drawbacks:
- Not included in all mobile plans
- Higher battery consumption
- Call quality depends on good LTE coverage
Not Included in All Plans
Although VoLTE is a modern technology, not all mobile providers or plans support it. Particularly in budget or prepaid plans, VoLTE may not be available. In such cases, users must rely on traditional 3G or 2G networks for calls.
Higher Battery Consumption
Using Voice over LTE can drain a smartphone’s battery more quickly than older call technologies because the device must maintain a stable LTE connection throughout the call. This can be noticeable during long calls or in areas with weak LTE coverage.
Dependence on Good LTE Coverage
For seamless VoLTE performance, a stable LTE connection is essential. In rural areas or buildings with poor LTE coverage, users may experience dropped calls or reduced call quality. If LTE is unavailable, the phone automatically switches to 3G or 2G, potentially causing delays or short call interruptions.
Key Advantages and Disadvantages at a Glance
| Advantages | Disadvantages |
|---|---|
| Best voice quality | Higher battery consumption |
| Faster connection | Not all providers support it |
| Browsing while on a call | Dependent on LTE coverage |
Conclusion
VoLTE is an advanced communication technology that significantly improves call quality. If you have a compatible smartphone and the right mobile plan, you can enjoy crystal-clear voice calls.
In regions with well-developed LTE networks, VoLTE offers substantial benefits. If you are looking for the best mobile plan, comparing different providers can help you find the best option.
