PRICING, COVERAGE, RESTRICTIONS
================================
DoubleCheck comes with 1 free check. For more checks, the following charges apply:

Checks = Cost
20 = 0.99$
50 = 1.99$
100 = 2.99$
200 = 4.99$
300 = 5.99$
The mobile operator of a number is found dynamically (is not received from a database). This operation is costly and as a result we are obliged to charge per check.

COVERAGE: Almost anyone in the world can benefit from DoubleCheck since it covers all mobile operators in 202 countries.
Full list of supported countries : http://www.doubleip.com/idoublecheck

RESTRICTION: For limited users with exchange and LDAP synchronized address books, the functionality of checking the mobile network is available but the information cannot be stored on the address book due to technical limitations. Also, it is not possible to synchronize the checked contacts with email clients that do not support custom labels (ex. Outlook). A workaround for this case is: from within the app, change back the label to a default one (ex. mobile), synchronize and then re-assign the found operator name to your labels. The process is straightforward and can be done within 2 minutes.

Also, please note that most MVNOs (Mobile Virtual Network Operators) are not supported, i.e. DoubleCheck will show the Mobile Operator whose infrastructure is being used by the MVNO.

HOW DoubleCheck CAN SAVE YOU MONEY
=====================================
You know your friend, George, is on AT&T (or Verizon or any other company), same as you.
Talking to AT&T numbers is free for you...
So you talk and talk and when the bill arrives you find yourself paying for calls you expected to be free !!

Why? Because your friend George has left AT&T and is on another operator now, BUT he kept his number.
