I lost mobiledata shorty after installing /e/ os on my fp3

hi
i switched to /e/ some time ago. noticed the mobiledata connection didnt work anymore. i didnt care much since i honestly dont use anything else than wifi and offline all my apps and such, but now i discover new roadblocks in how modern society wants you to interact with the infrastructure and need the 4g to open a mailbox.
exciting stuff, i know.

more details:

  • it says its connection but nothing goes through
  • 4g icon is there but all apps and browser gets timeout.
  • the same goes for 3g and edge.
  • the carrier triangle has a little exclamation mark
  • ive fiddled with settings on access point names with instructions from carrier support
  • they allso say everything looks okay on their end
  • im not 100% sure the problem started just after /e/ install
  • a few certain apps can go through. fbmessenger gets some messages and pokemmo can play with no problems. good connection too
  • i can even download android updates on 4g with ok speed
  • when i switch to mobiledata some apps react as if they get a sudden new surge of connection in a few seconds till it reminds itself “oh right. im offline”

is there anyone who may have had the same problem and found a solution?
or maybe someone know how i should troubleshoot this problem?
maybe its a problem i should tell /e/ foundation about?
or is it time to switch for a more reliable carrier company?
i know i went through alot of options after switching, could i have enabled/disabled something i shouldnt have touched? that includes dev options (needed that for the install in the first place)

any help at all will be highly appriciated
cheers
jonas

That sounds a bit like DNS issues. Did you try to reset Mobile carrier settings yet?
Settings → System → Resetoptions

I made it work!
thanks for the suggestion mr. switch, while your DNS suggestion didnt work by itself i got new determination and keywords for further searching and came over this site:

my APN settings was there with detailed description and tailored for my carrier, plot everything in field by field (mostly empty fields), push save, reboot and voila! 4g is back in business
whoever made this website deserves a medal since it was much more helpful than the supportpeople that actually get paid to know these things and the APN guide they had was heavily outdated.
i suspect it could be proxy (should be empty) or APN protocol (should be IPv4/IPv6) but i dare not test this hypothesis further.
had i known it was so simple i would done it months ago
hope this thread can help people with the same problem in the future
cheers

If some web services work and others don’t, then in case DNS isn’t the culprit the IPv4/IPv6 APN settings really are something to look into. Usually both are needed, but users have observed carrier APNs with only one of both configured, resulting in the trouble described.

I’ve just set up my fp5 and I’m also not getting any 4G with my sim. Same as you it says I’m connected. I’ve messaged my sim provider ill get back to you once they have a solution.
