SIM requirements to phone abroad from the US?
I will be traveling to the US soon and I will be expecting to make phone calls abroad from the US. Is it possible to phone abroad from the US with a Vietnamese SIM card with a Vietnamese carrier (since that is the SIM card I currently have)?
If not then when I do purchase a SIM card in the US, what other requirements, besides dialing the correct country code syntax, will be required for me to phone abroad while in the US?
Furthermore, if I were to buy a SIM card in the US, how will I enable access to 3G on it? Will this require registering with a post office/carrier centre ...etc? Thanks.
