Disclaimer This specific method is Canada only, however, I'm sure services like this can be found all over the world.
I recently started using this phone app called Fongo, it's based off of Voice Over Internet Protocol which allows you to call anywhere in the country so long as you have an internet connection. What's cool about this is that even on data, you can get about 12hrs of talk time with just 1gb. That's solely data usage assuming you aren't using wifi for the entirety of those 12hrs. Depending on how much you want to talk, you can get a data only service which accommodates your needs so it's super flexible. The best part is, whatever data you don't use is free data for the rest of the month. Unfortunately, texting is not part of the deal, however, you can get it for 20$ for 6 months. Another caveat to this is that it will generate a new number for you but contacts will still sync in the app.
