I too have Fibertel 3 megas and I work with clients in China and the US on a daily basis using Skype. BUT i would not recommend them. Their speed and volume is never as advertised and I have had very spotty internet. Their customer service is very poor in my opinion. My service dropped to almost nothing and after calling them, they were not able to resolve the problem for almost half a month (they had to redo their main wire to the building if you can believe it!). Even afterwards, their speeds are very irregular, though they say it should be fine now.
