Does anyone know the low cost way to call outside China to US, Europe ? Thanks

use a phone card ip 17968 card

Use Skype...

Skype is the cheapest, $0.02 per minute anywhere in the world and crystal clear sound most of the times.

Another option would be to dial 12593 then 00 + country code etc when you use China Mobile (0.8-5rmb/min)http://www.bj.chinamobile.com/index/engsite/support/nb/60890/

Indeed. Buy a skype out account and you'll be able to call for very low rates. Sound quality is good.

Hi,

VOIPDISCOUNT is the best. For 10 EURO you can use it for free as long as you want.USA,Canada,Hong Kong,most of the European country's landline is free to call.
The voice quality is good.

Download the program,install,register,pay,and use!

Good luck.

Steve

Same like the Voipdiscount posted above:

The trick is with all these companies, that you need to buy (at least) 10Euro credit by them, AND THEN YOU HAVE 90-120 DAYS TO USE THE SERVICE (either calling free destinations or paying destinations.
Sometimes they change the list of the free destinations without prior notice.
Conclusion: buy credit for 10euro and reload when needed, never buy credit for 100euro or so, even if you use up your credit frequently.

Beside all that, I am very happy with Freecall, instant connections, line breakup almost none, good voice quality.
Skype sometimes fuzzy.Freecall 99.5% ok.

if u have cmcc sim card just buy a 17909 card. When u make ur calls just dial 17909 then the number as u usually would. Really cheap
