Hi,
Last thursday I discovered that my fairphone wasn’t working properly: it didn’t recieve any phonecalls, nor could I make any phonecalls. It wasn’t on airplane mode, there were no error messages, apps seemed to be working fine (I had been using the stopwatch). After a reboot many messages (sms and whatsapp) ans voicemail notifications came in.
Can you tell us what version of Fairphone u are running?
Im using fairphone 1.6 (Cherry)
I have a similar problem sometimes. Interestingly only in specific areas, were i am offline without noticing. Do you have a data connection in such cases? I had not. In my case, switching Flight mode on and off helped always.
Also i believe that got better with the 1.8 update, but i am not sure if that is just coincidence.
I have that problem, that my telephonecompany has changed APN-codes, I believe it’s called…
They have offcause testet there codes on all phones 
Now my phone is roaming all the time and I cannot send mms’s…
I have run from Herodes to Pilates for help, and I switched to the telecompany with the best net i Denmark a week ago, because a simcard from there company worked on the phone…
But today I am back at schratch 
No mms… It started roaming again 2 days ago…
I dont know what to do and am pretty frustrated now…
I have consulted the cell-phone-guru of Telenor, who has given up, and we have together called FP in Holland…
HEEEEEELP!! 
Thanks Ben, i’ll install the update and hope for the best…
Any other people with similar problems?
Hmmm… I think I’ll wait a little bit longer before updating to 1.8 (Software update v1.8 temporarily postponed)
Maybe updating to version1.7 is an option?
1.7 was a os version that was only preinstalled on some devices but updating to it on other devices never worked.
but you could apply for the 1.8.2 beta program.
I am afraid you have to wait for 1.8.2 sadly. But i take part in the Beta currently and there is progress.
@RosaBorg could FP support not help your? I remember other people reporting the FP showed roaming while in the home network. This had no effect on their charges luckily. Anything new to report here?
