If you just make a couple calls or texts here and there and do not travel much a mobile phone that works is probably all you really need. If you're looking for a bit more or even just want to take advantage of features like free street maps so you do not find yourself lost in a big city, you should think about all the mobile accessories out there. You can even make calls for free with some of them. Here are the top 5 most useful mobile phone accessories.

1. Fring

Fring lets users make calls for free. Fring users can communicate with each other via mobile phone internet connection, for free, provided the two people connected both have Fring. The application lets you make video calls, engage in live chat via the likes of MSN Messenger and Google Talk, and connect with all your friends on Facebook and Twitter. One of the main selling points of Fring is that it does not use up the minutes or SMS texts you've bought from your mobile service provider. If you subscribe to a low-cost international calling service you might be able to connect the service with Fring so that you can call abroad for almost free and still not use up your minutes.
Fring is a mobile application that supports devices including the iPhone / iPod touch, Android, and Windows Mobile. Fring operates on accessible mobile internet connections (3G, Wi-Fi, GPRS, EDGE, WiMax).

2. FaceTime

If you have an iPhone 4 or iPod Touch you can get video calls for free. Connect with your loved ones on the other side of the world as if you're in the same room, all from your mobile. Keep in mind that both the caller and receiver must have FaceTime in order to share a video call.

3. Google Maps Mobile

You're probably very familiar with the amazing detail provided by Google Maps. You can now use the application on your mobile phone and never be lost again. Your phone must be equipped with GPS and have internet connection, but the service is free to download.

Google Maps Mobile is excellent if you're in your car and do not know the route to your destination. You can, of course, ask Google Maps Mobile in English where you are. Get rid of clumsy paper maps for good. Pedestrians who do not want to be seen with an ancient road map also find this mobile accessory worthwhile!

4. Car Speakerphone

It's now illegal to talk while driving in many countries / cities around the world. Even if it is not illegal to do so where you live, it is never safe. Car speakerphones, or Bluetooth car speakerphone kits, are essential for any driver who intends to make or receive calls whilst driving.

If you live in a sunny region, you can purchase a solar-powered speakerphone that does not require you to use an AC adapter or USB charger.

5. PIN-free International Calling Services

If you're looking to make low-cost international calls or even calls for free , a PIN-free calling service is an excellent choice. PIN-free means that you do not have to dial a million numbers from your mobile phone just to make an international call. The service connects directly to your mobile phone, and some companies even give potential customers calls for free.
