Currently, cell phone user services can be interrupted for a multiplicity of reasons. Sometimes digital mode services can become unavailable - consider the case where a user is in between cells or is in a geographic area where digital mode coverage is unavailable. In that instance, if the cell phone is set in the AUTO mode, it switches to an roaming mode to receive the call. This is, however, expensive for the user who may not wish to pay the extra charges for roaming mode communication for receiving calls from anybody and everybody. So most cell phones have the capability to operate in roaming mode but typically it is more expensive which is why users mostly tend to program their cell phones in Digital mode to operate in digital mode and switch to roaming when necessary.

Disclosed is a method to detect when digital operations are degrading/interrupted/ low in quality and then allow it to move over to an roaming mode provided the user has the appropriate authority. This will apply for receiving incoming calls where the owner may not be willing to pay the high roaming mode price for every call but may be willing to pay to receive in that mode for certain people.

The cell phone owner buys this special service "passive roaming" from the provider. The owner specifies:
a list of people who can activate this service for this owner a pass code which these people will enter to gain authorization to switch the particular cell phone to an roaming mode (which costs more) (possibly) under what scenario the digital-to-roaming switch can be activated The provider will activate the "passive roaming" mode for this owner's service which will provide it certain special (extended alternative roaming coverage) facilities.

When a user calls the owner and the owner is unreachable in a digital mode (between cell towers or no cell coverage). It is assumed the cell phone owner has activated the "passive roaming" mode.

the user has the option (if the cell phone owner has given him the access) to access the owner's phone in the "passive roaming" mode operation the user then enters the pass code to access the owner's phone in this mode the provider checks if this user ha...
