[Nexus 5X Q&A, Help & Troubleshooting] rezz93:
In the GSM mode of phone info the phone # displayed is the actual # of the phone.

In the CDMA mode the phone # is a completely different #. Same area code of the actual but different 7 digits.

When calling that CDMA # from another phone it rings about 10 times then goes silent.

Calling it from the 5X it goes to voice mail system and entering my pin allows me to listen to msgs.

There is a 3rd # also in the phone settings>about phone>status>phone>status>imei information listed under "Min". Same area code but completely different #.

When calling this # from land line it goes to voice mail...but that VM does not say Project Fi customer like the regular VM does.

Calling this # from 5X goes to same VM system. Leaving a msg does not come to my phone voice mail.

This sounds confusing because I'm confused. :confused:

My guess is this all has something to do with Google Voice.

Looking in /data/data/com.android.phone there are 4 folders. cache, code_cache, files and shared_prefs. The 2 cache folders are empty.

The files folder has 4 xml files.

/data/data/com.android.phone/files/carrierconfig-com.android.carrierconfig-89011201004001880640.xml

/data/data/com.android.phone/files/carrierconfig-com.android.carrierconfig-8901260971103773923.xml

/data/data/com.android.phone/files/carrierconfig-com.google.android.apps.tycho-8901260971103773923.xml

The shared prefs has 2 xml files.

/data/data/com.android.phone/shared_prefs/_has_set_default_values.xml

/data/data/com.android.phone/shared_prefs/com.android.phone_preferences.xml

The xxx #s are my phone number

The other 4 files have config info as well. Here's an example of one carrier config:
