SMS forwarding to an international phone number

I live and teach abroad but I need to stay connected to my bank account in the US, to Amazon, etc. I need to be able to receive sms messages to get verification codes on my phone but my bank will not accept an international phone number. I have read of android apps that will forward sms messages to another phone number or to an email. Does anyone have any experience with one of these? I have an cell phone in the US with an active phone number.

 

Thanks! Google voice does not work outside of the US - Google's decision, not the other country. Also, the app needs to manage an international phone number - 2 digits for the country code and then 11 digits for the phone number
