A revolutionary new caller app for people who need more than one telephone number for business or personal reasons but pockets full of separate sims or cell phones and forwarded landline numbers does not appeal to them!
Wouldn't it be great if there was some way to have lots of different telephone numbers in one place, on your mobile?

Call your London Agent on your US or UK Number from Spain - or select and install a Spanish number and use that!

How much easier would your life be if you could have all your different contacts easily organised and categorized so that you always call them from the right number…all from the one phone?

What if you could purchase different landline numbers from any country in the world* and have them all on your ONE phone, using your SIM and your mobile phone carrier?

What if having all that was as easy as downloading a FREE app?

WorldMobile Solution's Caller App is the only caller app you'll ever need.

WorldMobile Solution's Caller App has been designed to be the most flexible and user friendly service in the world. It is truly versatile, with both GSM and VoIP calling capabilities, switchboard integration and is 100% operator independent.

The Caller App offers additional features never before seen on mobile calls like the Replicall service (Replicall - verb: to repeat, duplicate or reproduce a phone number when making a phone call - replacing the originating phone number with a copy of another one).

The Replicall service allows you to transmit a different phone number from your original cell number to the recipient – this is incredibly powerful for anyone in business as customers could be shown your company’s main phone number, for example, rather than an individual employees’ mobile number, creating a better overall image, and greater call control for the company.

Active ‘grey lists’ have been incorporated which allow you to always bypass the app for selected contacts if required and ‘blue lists’ which allow you to select which number to use every time for certain contacts or your original mobile number for different contacts, ideal for those who run several businesses.

By enabling you to transmit a different phone number to the recipient of your call your cell phone has now become a powerful tool both in business and personal arenas.

And what's more, for peace of mind, in the era of security and hacking concerns, our Caller App encrypts every phone call using SS7 and https encryption technology.
