What I am trying to say is that you cannot buy a USA SIM card until you arrive in the USA. There are two kinds of phone systems in the USA, GSM and CDMA. GSM is what is used in Singapore so you can only use a GSM carrier in the USA.expat6023 wrote:Hi
Does that mean I can't use USA SIM card after arriving USA?
As i know, Singapore phone can use every countries' SIM card.
Am I wrong?
Appreciate for your reply.
Thanks
AT&T offers pretty much the same thing as well... now... didn't a few years ago. First couple of times I came back to the USA, only T-Mobile offered prepaid... last few years, 2009 onward, bought from AT&T for a comparable price.zzm9980 wrote:Singtel has a roaming plan where you can do data roaming in the US for something like S$20 per day.
Otherwise, what Strong Eagle said. Depending on how long you'll be in the US, T-Mobile will probably be your best bet. They have no-contract sim cards which would give you a month of 4g for like $50 USD a month.
