Disadvantages of wifi calling

Wifi calling is a great way to make calls when you don’t have cell phone service. However, there are some disadvantages of wifi calling that you should be aware of. In this blog post, we will discuss the cons of wifi calling.

wifi calling is not secured

One of the biggest disadvantages of wifi calling is that it is not as secure as traditional cell phone service.

This is because your calls are routed through the internet, which is inherently less secure than a dedicated phone line.

Additionally, if you lose your connection or drop your call, there is no guarantee that your conversation will be picked up again. This can be a major problem if you are in the middle of an important call.

Annoying-Incoming-Call Attacks

This is where someone could make a call to your phone because the call would come over the internet.

The person on the other end could then just play an extremely loud and annoying sound, making it impossible for you to use your phone.

This could be a major problem if you rely on your phone for work or other important communication.

Intermittent Mute Call Attacks

In this attack, two people on a Wi-Fi call are both victims. The attacker doesn’t try to end the call, but instead just mutes the victims’ voices for a period of time.

Telephony harassment/Denial-of-Voice-Service Attack

This attack makes it difficult for people to have a conversation on a Wi-Fi call. The attacker lowers the quality of the call so that it is hard to continue.

Is Wi-Fi calling is safe?

Yes it’s completely safe despite a few disadvantages

When should I use Wi-Fi calling?

If you’re in an area with very poor cell service, your call quality will likely be much better over a WiFi connection.
