863678 - APN Settings: automatic configuration does not work for MVNO users

Status: RESOLVED WONTFIX

(Firefox OS Graveyard :: Gaia::Settings, defect)

Description

[Fabien Cazenave [:kaze]]

Steps to reproduce:
 • use an FxOS device with a *new* SIM card
 • Settings > Cellular & Data > Data settings
 • see the list of APN presets matching the current SIM card

Expected result:
 • the APN preset matching the current SIM card is selected

Actual result:
 • the *first* APN preset matching the current SIM card is selected

At the moment we only rely on the MCC/MNC tuple to filter all “compatible” APN presets. This is fine in most cases because there’s usually only one operator per MCC/MNC tuple, but it can be an issue for some operators, especially with MVNOs.

As an example, 208/10 matches SFR and all the related MVNOs (NRJ, Coriolis, Keyyo…). So if a user puts a Keyyo SIM card into an FxOS phone, the default APN settings will be the ones corresponding to SFR — which will probably not work.

We should use the SPN info (which is also stored in the SIM card, along with MCC/MNC) and compare it with the “compatible” carrier names to pre-select the most likely APN preset. This should be enough for most MVNO users.
