Good VoIP Apps?

[Titanmowgli]

I'm looking for a good VoIP app to use in conjunction with a data only plan.  I plan to port an existing number onto one of these VoIP services.  I know that there's a bunch out there - Fongo, TextNow, TextPlus, etc.  Any recommnendations on which one would provide the best value, quality, etc.?

I've always just used Skype and with a small subscription that comes out to less than $2 a month, you can excellent quality. Calling landlines from it works great and is ideal when traveling.

I've got a voip.ms account that I would love to use all the time, however the SMS isn't fully functional.  It does have an SMS web interface, but that's too clunky for me at this time.

I've got an android phone, so I've setup the voip.ms account on the native dialer, alongside the regular settings for Public Mobile.

By default I use the PM settings for phone calls, but my voip.ms will ring in when someone calls, and I can select that account if I want to make a long distance call.

Google Hangouts. My sister uses Fongo with a data only plan and purchases their texting plan.

magicjack as well, can connect it to your house system and use as a landline and as a mobile line ith their app.  I started  to use fongo as it gives a free number and free calling to most of canada

Try Fongo. Gives you real local number. Good voice quality. Good luck.

Voip.ms (especially if you are in west coast)
