Do you need to check the phone hasn't been locked to take Optus only SIM cards first?

Not just Samsung phones but most phones including the new iPhone are sold as region-specific devices.

In the USA you're always better going with AT&T for a number of reasons: (a) AT&T use one main 4G band for their network across the USA. In contrast T-Mobile use three different 4G bands. So unless your phone has all of these three 4G bands you might not get 4G with T-Mobile in the areas in which you're traveling, (b) the AT&T network is far superior outside of major cities. In contrast T-Mobile has less native coverage outside major cities and often relies on local partner networks for coverage and if you roam onto such a partner network you get a measly data allowance whilst roaming in that area (eg I think it's only 100MB or so).

Most major smartphone brands have near worldwide compatibility these days (with the exception of CDMA for Australian phones). You can check the compatible frequencies at GSM Arena by searching the model number of your phone. You will almost definitely not have an issue however.

Agree. AT&T is usually a better bet.
Yes I have done.. It's not :)
I have heard that. Just wondering if it was worth paying the bit extra. Looks as though I probably will.
So even on an umlimited data sim I'd be limited to 100MB in certain area's?

I'm on TMobile in the US for the last 5 years and I have to say that the coverage is really really good now (it wasn't a few years back). I travel a lot and have rarely been without service.
This page has the info on the bands (https://support.t-mobile.com/docs/DOC-4988) but the main ones are below. So long as your phone supports these bands you are good to go. Most phones support these, and many more, for when people travel internationally.
TMobile has much better rates for short term trips. Have a look at this one. https://support.t-mobile.com/docs/DOC-26344
And no, I don't work for them. I just despise AT&T as their coverage when I was with them was not as good.
Hope that helps

disastrous initial trip where I tried to buy a SIM locally and was bounced from pillar to post, eventually resorting to Starbucks free Wi-Fi
for the duration …. I now buy an AT&T SIM online and provision it up before we leave (but only turn phone with AT&T SIM on once you land IN USA).
I have done this on a couple of different Samsung Galaxy phones when we visit USA. Apart from one instance where the phones locked on to some random carrier and I had to manually switch them back to AT&T and an overnight in a log cabin just outside Yosemite, I have had fabulous coverage and ease of use in both cities and rolling plains.
Cheers everyone - Seems like AT&T is the way to go as I'll be spending some time out of cities.
