moblie phones

Anyone know where they sell these sim cards? I understand that these cards are prepaid but in what amounts do they come in? Lastly, I'll be using in to check in with family back in the U.S and was wondering how much it would be to call per minute. Thanks for the help folks!

Any shop selling mobile phones with the sign MobiFone/VinaPhone or Viettel can help.

Check these websites for details:
MobiFone
VinaPhone
Viettel

Calling rate from US is around 10-15Ct/min.

Thanks for the info. RB! Is there a difference in service between the 3? Which one do you recommend?

I've used Mobifone for the last 2.5 years with no complaints. Can't remember having a dropped call and they have good access to the internet.

They all operatve a GSM 900 network each. MobiFone is a swedish-vietnamese joint venture. VinaPhone is a state run company and Viettel is a business arm of the military.
I would go for MobiFone. They have the first mobile network in Vietnam and from my experience best reliability/coverage. MobiFone is a roaming partner of Cingular, so you can probably page home for 0.16$/msg.
If you want to call home from your mobile, get a calling card. The rate is approx. 0.12$/min

nicky we are heading there from NZ in 3 weeks and my wife asked NZ Telecom the same kind of question and they are loaning us (at no cost but the calls) a phone that we can use there. While calls will be expensive to NZ txting isn't.
