Subject: [PATCH] MNCs not in carrier_list can get the wrong MNC value
|
|
|
|
Mobile Network Codes that belong to SIM cards not specified
|
|
in carrier_list sometimes get the wrong MNC value.
|
|
|
|
This change aims to improve the likelihood of a
|
|
correct MNC.
|
|
|
|
Test: Install an RRO with apns.xml and look at the DB.
|
|
