There are two steps: set up an incoming number that you can divert to cheaply from your existing US number, and then have a method to forward that number cheaply to a UK mobile. In the US, most VOIP companies do not offer free incoming numbers, so it gets complicated.

What sort of number are you forwarding from? That's the first step, to work out where that can forward to at a reasonable cost. If it's a US cellphone, it can likely forward for "free" (plan minutes) to any US number.

If your US cellphone can forward to a UK mobile, what would the rate be? That might save a lot of bother if affordable, but I doubt it is.

So, you need a US number to forward to. ipkall.com does free numbers. These free numbers need to terminate at a VOIP account.

So, you next need a VOIP account (anywhere in the world) that has good rates for UK mobiles, AND will accept incoming SIP connections from ipkall. I don't know about voipcheap specifically, others can maybe answer if they work with ipkall.

(you could also get the US incoming number, and the voip account, from a single provider, although there is then usually a monthly charge for the number).

So the way it works:

1. divert your US cellphone to the ipkall (or other) US number
2. set up the ipkall.com number to reach your SIP account at the VOIP provider (if you get the US incoming number from your VOIP company by paying a monthly charge you don't need this step)
3. go onto the voip provider's account panel and set up an unconditional divert to your UK mobile, which will be charged as an outbound call

Set up a couple of alternatives, in case one turns out to have unacceptable delays or quality.
