I know a little bit about Google Voice, but overall I am a newbie. Can you please explain?

Doesn't T-Mobile roam in Mexico too? It's a lot cheaper to keep it going ($100 first year, $10 a year thereafter) and it works in Canada too as an emergency phone. AT&T does not roam at all in Canada on prepaid.

It does indeed, but isn't it about 1.49 $/minute? I know it's much higher than their Canadian roaming rates.

I hadn't checked on that. It could well be.

Good News Canada Is Included.

That's a good deal
 

Sweet. Thanks for testing. I just bought 2 GoPhones for my trip to Cancun. No other provider seems to come anywhere close to $0.25 per min.

My wife just got back from Cancun and the AT&T 0.25/min worked great.
A bit of a hassle adding money from Canada as the GoPhones don't roam here.

You can add money using the AT&T website.

I have mine auto-top-up by $25 every three months to keep it alive.

I made a mistake by activating it online from here so they messaged the account password to the phone which dosen't work in Canada! I picked up an online voucher and phoned them and they added the money but said they will charge $5 next time. Forgot to get my wife to get the password while she was in Mexico and the phone was working. Next time we are in the US will get it set up properly. I think they have a $100 topup that is good for a year?

You should try to get your AT&T top-up vouchers from a reseler such as BabbleBug or Callingmart. The usually run a 8-12% discount scheme and charge no sales tax.
