If you don’t feel that you can setup an US phone number with using this relatively simple to follow guide, I will recommend that you contact your technical savvy friend and see if they will help you. If they are willing to help you, then take them out to lunch or dinner as a way of saying thank you. Still, I will imagine that this tutorial will be easy enough to at least read through to see if it is something you would be willing to challenge yourself in setting up on your own.
