Thanks, donnaw. Forgot to say I'll be bringing my iPad only this time. I'm there every year for business and this is the first time without my notebook. I've always stayed at the Four Seasons and have access to their wifi. Good point I should check what my costs are with them as I take it for granted as a necessity for my travels.
I have the new iPad purchased from Apple and here in Montreal, Canada for that matter, does not distinguish which carrier you use. I was told it should work on either. Anybody know for sure?
The Cdn new iPads are basically compatible with AT&T's network.
You will need to obtain a microsim from AT&T or an Apple store. I have heard you can get them free from an Apple store by asking, but might have to pay at an AT&T store.
For billing info, the easiest is if you have an AMEX card. Use the hotel address. You will need the postal code as well as the phone number as well. Just use the hotel main line and address. If you don't have an AMEX card, you will have to get one of those prepaid Visa cash cards. I tried to get it to work, but I was never successful. I have read that other's have had success.
The best plan is the 3Gb for $30. There is also a 5Gb plan for $50 and a 250 Mb plan for $15. All last for 30 days. You can activate the plans on your device.
You can also cancel your plan before the 30 days are up and this can be done in Canada. I have activated a 3Gb plan in Canada, traveled down to the US and then connected without any issues as well as cancelled the plan in Canada. This was with my iPad2, but I don't see why it wouldn't be the same for the new iPad. I will be heading down soon to pickup a new LTE AT&T microsim for my wife's new iPad so I'll confirm for the new iPad later. .
As for hotel WiFi, depending on your physical location the connection could be spotty. As another poster stated, it would probably be cheaper just to use your iPad. If you install a remote desktop app, you could even log into your work laptop at home.
I would be interested in hearing your results when you get back form Vegas.
