Well i use VOIP (Skype) to make free calls to my sister currently abroad. She has skype on her pc and skype to skype calls are free. talk as much as you like for as long as you like for free. you can downlaod aplications such as “fring” for free as a VOIP application for your phone. all you need to make sure is that your current tariff has data included. In terms of quality ive never had a problem calling via skype. also using skype you can buy call out credit so you can phone londlines and mobiles aswell. very cheap to do.

Maybe u should try out the Cordia VOIP Magellan plan at http://www.magnumbers.com/ . Cordia VOIP Magellan plan enable callers to dial the Magellan number that they provided to u and reach u on the landline or mobile phone wherever you are in the world with their local rates.

Or u can try out Cordia VOIP other plans at https://www.cordiaip.com/

They are running a promotion right now where u can enjoy the first month free for all Cordia VOIP plans. The promotion code is AGLEEX182X.

Good luck.
