Having an Internet connection can be used to make free phone calls thanks to the VoIP protocol. For this you only need an application like Nextplus that provides you with your own number.
Free calls and text messages
This application gives the user a phone number with which to call and receive calls in addition to sending text messages (with attachments or GIF animations). And the most important thing of all: it's free as long as you communicate with other users of the app... otherwise, if you call numbers that don't belong to Nextplus, you will have to pay the corresponding charge.
It is advisable to do it through a wifi network unless you have a good data plan with your operator. These are the main features of the app:
- Receive a unique phone number for free.
- Call and receive calls.
- Send and receive text messages.
- Meet people with the Lucky Call feature.
- Send emojis, GIFs, attachments or voice memos.
- See which contacts are online.
