4. Using free Apps
There are lots of apps that let you send SMS texts for free, but mainly to USA & Canada phone numbers.
Apps such as: Textme, Textfree, Text-Now, Talkatone, Free-tone, etc. But we don't recommend such apps, due to their strict limits & unreliability.
5. SMS via Wi-Fi
Yes, you can. Most smartphones can send and receive SMS texts & MSMS messages via WiFi, instead of cellular data.
You need a robust app for this, we recommend Signal app for this purpose. But you have many choices out there.
