Six iPhone Apps That Could Save You On Your Voice Plan

My friend recently told me about how he had to pay for overage fees on his iPhone 3G data plan in the past two months. He mentioned that because of this, he was going to try and save on both voice and 3G data plan by going offline whenever there is WIFI coverage. I thought it made perfect sense because in the normal course of a business week, he would have WIFI connectivity when he is in the office and when he gets home. Doing this would allow him to reduce his monthly limit from 1GB to 500MB.

In addition to the 3G data plan savings, he also said he can further save on long distance voice plan charges. He downloaded a few iPhone apps that he could use without using up any airtime. As long as he has WIFI or is connected to 3G, these apps will allow him to avoid using precious phone airtime:

MagicJack
This app let’s you call to any phone, as long as you already have the MagicJack hardware plugged in at home. Free calls in Canada and in the US.

netTalk
Can call anyone, including non-netTalk users and it’s free in Canada and in the US. My friend says this is his favorite so far.

UWewe
Registration is based on a real phone number. Allows you to call other UWewe users for free or any phone all over the world at a discount. The best thing about this is that you have 20 minutes of free calls per day, my friend says.

Viber
Lets you make free phone calls anywhere in the world and send text messages to anyone who also has the application installed. The username is your telephone number so it makes it easy to call anyone who also has the app installed. http://helpme.viber.com/index.php?/Knowledgebase/Article/View/18

Allows users to send and receive instant text and voice messages for free, to other Weixin users. http://chineseculture.about.com/b/2012/02/04/wei-xin-app-gaining-popularity-in-china.htm

Skype
Use this to talk to other Skype users for free, but discounted to any phone. Very popular because it’s so cheap.

I haven’t actually used any of these iPhone apps. What’s your take on any of the 6 listed here?
