I have United Mobile sim and will be traveling to Europe. I plan to use callbackworld for all outgoing & incoming calls. My clients have my 1800 + pin number from callbackworld which will reach me on my cell phone. I have tried it out & it works fine.

However - I see UM uses the callback system also.
UM rate - 0.39 Callback 0.14

When I dial out using callbackworld I have a 909 callback number to call, hang up and then I receive a callback & then dial any number.
How I do I know that my callback is coming from callbackworld and not UM?
