“Call Me Free” – How it works!
Users in the USA share a “Call Me Free” number with folks back home. To call you, they first dial a local Call Me Free number. Ultra Mobile answers and prompts them to enter your Ultra Mobile USA number. Ultra Mobile then connects the call for Free.. “Way Coool”. Local numbers are available inthese 44 countries.
