The service is a full unlock the iPhone from regional lock on the EMEA. This service can unlock all models and all versions of modems and firmware. Once fully unlock the phone can be upgraded to any version of the OS. The main requirement - in your test result by IMEI must be a string: Next Tether Activation Policy Description: EMEA Service.
IMPORTANT: Any other information in the line "Next Tether Activation Policy Description" means that the service can not be ordered. An example of this information:
Initial Activation Policy Description: 55 - EMEA Service
Next Tether Policy Details: 1 - Factory Default Policy
Lock Status: Locked
In this case, the line "Next Tether Policy Details" contains other information. Despite the fact that we are seeing as a result of checking the name of the "EMEA Service", a service order for such a result is impossible.
