It’s called Google Voice.
You sign up online, get a regular number that you can set to ring either on your phone or on the Google Voice website.
You can also get sms messages either on your phone (not applicable in your case), an/or on the website, and/or forwarded to your email.
It sounds like it would work in your situation as long as you have a computer with internet access (it might work for your ATM card too)
