I have BB9700 and Optus is the server in Australia. If I go on holiday in Vietnam, what sort of SIM card I have to buy so that I can use both for voice and Blackberry internet.
Thank you very much

You will likely not be able to get BlackBerry service without a contract in Vietnam. Viettel Telecom is the only BlackBerry service provider in Vietnam, and from what I can tell they do not offer this service on PAYG.

Thank you for your info Lusty. In that case, I can only use it for voice calls like an ordinary mobile, can't I?

Correct.
