If your friend already has a USA cell phone or spare phone line, she could set up call forwarding to the prepaid European number. Alterna- tively, if you search on Google, there are a number of companies offering virtual number and 'follow-me' services, providing a US based number which can be forwarded internationally at rates that are not too expensive.
This may become extremely expensive if she is paying both call forwarding and incoming roaming rates with a prepaid roaming SIM, versus a country-specific SIM where generally only the call forwarding rate would apply.
