3. Benefits of VoWiFi

VoWiFi means

VoWiFi can be used to make calls in places with weak mobile signal coverage, but that is not where the advantages end. Here are some of the most significant ones:

  1. Enhanced Coverage: VoWiFi removes dead zones, making it possible to receive calls or make calls even in places where you would have very little mobile network signal. A dependable Wi-Fi connection guarantees flawless communication whether you are in an underground parking garage or a remote mountain cabin.
  2. Cost Efficiency: VoWiFi allows users to make phone calls without dealing with complications or additional fees related to cellular services because calls made over Wi-Fi are generally free. VoWiFi is a great option for people with prepaid plans or for those who travel abroad and wish to escape exorbitant roaming fees.
  3. High Definition Voice Quality: VoWiFi resolves the issue of blurry voice calls over the phone. This is because the technology uses a connection over Wi-Fi, which is faster than 4G and even 5G networks in some cases, guaranteeing better voice quality.
  4. Experiences of the User: VoWiFi, in contrast to OTT apps like WhatsApp or Skype, integrates into your phone’s default dialer and SMS apps. Therefore, you don't need to download any other application to reap its advantages.
  5. Being Environmentally Friendly: The use of cellular towers is lessened because calls are routed via Wi-Fi, which greatly benefits the environment and reduces energy consumed within communication systems.

4. VoWiFi vs. VoLTE Comparison

VoWiFi means

Many telecom operators around the world currently offer VoWiFi, which is a continuation of the advancement of communication technology alongside Voice over LTE (VoLTE). VoWiFi and VoLTE have the same purpose of improving call quality, but they operate over different networks and have different features. Read the comparison below.

Feature VoWiFi VoLTE
Network Used Wi-Fi Network 4G LTE Cellular Network
Signal Dependency Relies on stable Wi-Fi or mobile data Depends on a strong mobile signal
Call Quality Offers high-definition (HD) voice quality Also delivers HD voice but can be affected by congestion
Battery Consumption Generally lower due to efficient Wi-Fi use Moderate consumption as it relies on cellular towers
Coverage Ideal indoors or remote areas with poor mobile signal Wide coverage in most urban or sub-urban areas
Roaming Costs Often lower or free when using home Wi-Fi networks Can incur additional charges on roaming

Note: The efficiency of either method may change depending on the policies and infrastructure investments of your network operator. For further comparisons, check out reviews from Verizon’s official blog and other trusted blogs.

5. Pros and Cons of Using VoWiFi
