Free long distance calls including International calls

Free International Long Distance Calls Talkster or FreeRinger

Note that Talkster is no longer free beginning of the year of 2010.

Talkster provides free International phone-to-phone calls including landlines and mobile phones. As of today, it supports 38 countries. I have been using it for a year already. You don't have to sign up before use. Simply go register your phone and your callee number in exchange for talkster numbers and then you both are ready to call each other.

Each call seems to be limited to 2 hours.

If you don't use the talkster number for a while, you may not be able to use it and call. In this case, you may get a busy signal saying the line is not available or something. Simply go to Talkster again and re-input the numbers; the problem should be cleared itself.

FreeRinger uses Talkster service to provide free calls. With FreeRinger, you don't have to use a physical phone to make calls. You can make calls via Computer-Phone and send/receive calls via your SIP phone. There is absolutely no software download and it is completely online. However, you have to create an account with them first. This feature is great for off-country traveling, or you don't want to use a physical phone to make calls.

Free WiFi Locator: JiWire
It lists all available free WiFi hot pots in 140 countries. The service will be no use if you don't have an Internet to access it first. Thus, you would be better to do the research of the location while you are being connected.
