List of Free Calling Softwares

Below is the list of free voice/video calling software applications for all major operating system platforms which can be used with Mobile Phones as well as desktop pc. Using these softwares services you can call the other party with no charges at all. Because these softwares use the VOIPtechnology (Voice Over Internet Protocol). Voip is a method of transmission of voice signals, multimedia signals over the internet. With voip you can make call using internet connection/wifi instead of your service provider’s network all over the world. But there are some conditions –
1. Both the parties should have an internet (For Mobile Phones preferably 3G network/WiFi connection is required).
2. Both the parties should have this software installed.
3. Call can be placed and received only if this software is running.

    • Skype:

Most popular software and freely downloadable app on the net. This software supports all major operating systems like Windows, Apple’s iOS & Mac, Android and Symbian. Both the parties should have an account on skype to access the service. With Skype you chat using their instant messaging and you can call from skype to skype on –
1. Mobile to Mobile
2. Mobile to PC
3. PC to PC
Mobile to Landline or PC to Landline requires a premium account.

    • Tango:

Tango application is also free calling service. It uses the same address book as that of the device, synchronizes with it and shows a tango tag against the contact if they are registered to tango hence with just a click you can place a free call to the tango user. This synchronizing feature is not available in the Skype. It works with iPhone, Android, Windows Phone, Windows PC. It can be downloaded freely from app store or android market place and registering on tango is quiet simple and easy.

    • Viber:

Viber application also allows free calling and sending messages. It’s a lot simpler than Skype but it you can’t make video calls from it and there is no desktop client for talking to those on a computer but it does have some advantages, such as the lack of need to create an account. Viber just uses your mobile number to make the calls (although the actual call is made over the Internet) and similar to tango viber also uses your existing phonebook numbers instead of having to create and add new contacts, as on Skype. If you just want to talk to someone using an Android or an iPhone (a version for BlackBerry phones is in works), Viber is a lot easier and simpler choice.

Detailed Review: Nokia N9

Nokia is one such company which always try to innovate and develop new stuffs. They never try to jump on the hot technology which isn’t developed by them, like Android. Similar to Apple they use their own technology for their devices. 2011 was not a good year for Nokia, it faced loses, laid off the employees.
In the month of August 2011 they introduced a new Smartphone Nokia N9 based on the new Os called as MeeGo. In the Nokia Nseries N9 is the first Smartphone based on MeeGo 1.2 “Harmattan” Os. MeeGo Os is a Linux based open source operating system targeted for Mobile Devices, Netbooks, Tablets and other consumer electronics like IPTV. But the company has already announced that it will not return to MeeGo for its Future devices since it has planned to use Microsoft’s Windows Phone 7 Os.

    • System:

N9 is built on Texas Instrument’s OMAP 3630 which is a system on chip controller which includes three other processor in it, the main core being the 1GHz ARM Cortex Processorresponsible to handle the applications and the Os tasks. The other two processor help in the the image processing, audio processing and data transmission. Phone has two versions based on the fixed storage space, 16GB & 64GB, this means there is no expandable memory card slot. 1GB of low power Mobile DDR RAM. Battery is integrated in the device. It means we can’t remove the battery, if anything bad happens then we have to send it to company for service. Battery life for GSM phone is 11 hours and WCDMA its 7 hours and is charged using the micro usb. This phone uses Micro-SIM card slot. So if you have a mini-SIM card (which most of us have) then contact your operator to replace it with micro-SIM card. As per the company you can run numerous apps simultaneously like games, maps, video player, camera. There are very few external keys, Lock/Unlock key, volume control and a reset button. This means the phones uses touchscreen as the major user interface. Phone works with full featured sensors like –

Accelerometer – Used to change the display orientation from landscape to portrait & vice versa.

Proximity sensor – deactivates the display and the touchscreen when the phone is brought near to face during a call.
Ambient light detector – Adjusts the display brightness automatically.
Dual microphone – Helps in cancelling the active noise while on call.

    • Display & Camera:

N9 has a 10cm High definition AMOLED display with the capacitive multi touch functionality and with aresolution of 854 x 480 pixels (FWVGA – Full Wide Video Graphics Array). This display looks sharp in the direct sunlight & it is built using Gorilla technology. It means the glass used for the screen is scratch resistant. There are two cameras on phone front and back which helps us during a video conferencing under a 3G network. Front camera is a VGA but the back camera is a 8MP, 4X Digital zoom with auto-focus and dual LED flash. The Carl Zeiss lens does a great job of capturing the moment.

    • Music & Connectivity:

There is a 3.5mm AV connector and a High speed USB connector. This AV connector can be used for video output where we can connect it to TV and watch videos from the phone. But as i mentioned before there is no HDMI connector in this phone. Other connectivity includes WIFI, GPS, VPN support, Bluetooth 2.1, NFC (Near Field Communication) and FM Transceiver.

    • Availability and Price:

The Phone is not available in the giant market in the Western countries it means no US, UK, France, Germany.
For the countries where Nokia N9 can be purchased directly please refer the Nokia site. As i mentioned earlier that the company has no future plans to produce anymore smartphones using MeeGo Os but there will be full support given for the released phone both for hardware and software. Price of N9 excluding taxes and subsidies ranges from EURO 480 to EURO 560depending on the handset memory storage space. This phone may be having some drawbacks but has won many hearts of its users.
