I have a WileyFox Storm [kipper], and I recently upgraded from CM13 to LineageOS 14; it has one EE contract SIM (I'm in the UK). After flashing the ROM, I discovered that I now have more APNs than I had before (I used to only have EE Internet and EE MMS). I know have EE Internet, EE MMS, Asda Mobile, T-Mobile Broadband, T-Mobile Internet, and T-Mobile PictureService.
Can someone explain why I have so many now? It is, by default, selected on T-Mobile Internet, and I have actually seen a much larger coverage of LTE than before around where I live.
Is there a benefit to having this many? Which one should I select with the radio button?
