I love using this app! I do not have a cell phone and I can call anyone locally for free on my tablet. The only downside for me though is that the app only works when WiFi is available, but since most places have WiFi access now, it isn't much of a problem. One the best features of this app is the option to have add-ons. For a few dollars extra you can add texting and/or long distance minutes. All in all, it's a great way to stay in contact with everyone since I added the texting option to my tablet! A must buy!!
Tried it on my smartphone and it worked great, now I put it on my android tablet and it won't let me add any contacts,says the app is not working and in error, contacted support,looks like I won't hear from them in a hurry,good thing I'm only out $1.99 Canadian,,gonna uninstall it and never use this crap again. What a rip off
Greatapp I installed on my old Samsung Galaxy S3 which was an old Bell cell phone. I use it as a home phone through my home wifi. It didn't cost me a cent to get a new phone number and use. Can call most major cities in Canada for free no more long distance charges. Better than those other Internet home phones as I didn't have to buy an Internet adapter or pay monthly charges. I don't use sms texting as I use Viber for that which is free too. Quite happy to have a free home phone. (PS I also have it installed on my tablet too.)
I installed this on my Kindle fire so I would be able to make phone calls on it. It works great. Very rarely it cannot connect and by this I mean if I change the wifi I'm using the notification turns red instead of green. I just have to open it and it reconnects. Just be aware of that and you have a great free phone app. I also installed it on my kids phones so they can have free calling on wifi too.
