@muskist Ok, thanks. I'm using a Fairphone 3+ and changing to 2G doesn't make a difference.

@muskist Did you experience that on a Fairphone 3 or a Fairphone 3+?

@luksus After a week of using it as my daily driver I want to give some feedback: I can confirm all points from your edited first post. Mobile data is not working at all on my FP3+ (no matter if 2G/3G or 2G/3G/4G).
I`m impressed how stable it is running at this early stage. I used a Nexus 5 with UT before and expected the Fairphone 3+ to be more buggy, because the port is not as matured yet. Keep up your great work!

Hi @luksus, first of all: Thanks for all your great work on this port. I installed it on my Fairphone 3+. In my case, I had to wipe the data partition using TWRP.
