5 stars: this app has worked for years for me. never charged me a cent, doesn't make sense but I'm not arguing. it's come through for many times when my paid for cell phone has been busy with not operating properly and all you need is Wi-Fi. if you've been used it in places with low signal and still had clear phone calls and definitely text that work from those places
5 stars: Great service - same network as T-Mobile. I get a $9 invoice every month and still have unlimited calls and texting with 1GB. If you use this app, turn off
4 stars: I like the app really useful to make calls when you have no data just one problem I have with it. It's really hit or miss with notifications if someone calls me sometimes it'll ring sometimes it won't same with texts it occasionally will give a notification but occasionally it will not either. I'm connected to WiFi so they should be getting through and notifying me or ringing but it just doesn't sometimes.
3 stars: Good for what it is. Love that it imports all old messages when logging into a new device. Hate how sluggish it makes my phone, the frequent crashes, and how agonizingly slow the ap takes to start up, which is nothing compared to suffering I endure, each [usually failed] attempt @ answering calls...due to everything becoming unresponsive as I repeatedly & frantically press 'answer' until the call goes to Voicemail.
2 stars: It's an ok app, but quite often I have to log out then log back in just to see new messages...
