Hamra- I haven't been having any problems with Skype lately. I used it yesterday to videochat with my parents-- but we used to have random problems with Skype and vonage in previous houses, so who knows
I use a lot of apps regularly - but these require the other person to have the app:
-I really like Viber for calls. I think it's the best- but it requires the other person to have a smart phone. I also use it for text messages and video/ photo sending
-I also use what's app all the time for text messages, video/ photo sending. I prefer Viber, but not as many people have Viber it seems.
-A few of my friends contact me on Kakaotalk-- which is good too.
-You can leave voicemails with people using Voxer. I don't really use it myself, but it was popular about a year ago.
I use facetime for people with Mac products.
We still have an old Vonage number that we have been to lazy to disconnect... we pay too much for it, and keep talking about discontinuing it, but haven't yet.
edited to add costs --
The costs depend on who you are contacting. IF you and the person have a smartphone and the same app, then the calls/ sms/ etc are free using skype, whatsapp, kakaoutalk, viber, voxer.
If the person does not connect using a computer or a smartphone, then you are pretty much limited to Skype. And then each country has different rates.
I think it's worth paying to have a highspeed internet connection in your house so that you never have problems with these various apps/ programs.
That said, I also call the US on my Q-Tel cell phone a lot... but I pay an extra QR 100/ month to my plan for some sort of international plan and I get a ton of minutes I can use to call internationally.edited by JillMV on 28/07/2013
