Just wanted to post this here, since I couldn’t find information on it when googling.
If you are Norwegian and have HappyBytes as your carrier, you will experience problems with calling. If 4g calling is off, some calls won’t make it through, and you’ll receive an SMS about a dropped call. If 4g calling is on, calls will go through, but be listed as “unknown caller”.
This apparently affects all Fairphones according to HappyBytes. They’ve tried to reach out to Fairphone to get it fixed but haven’t heard anything yet.
Please be aware of this if you are experiencing problems, or considering purchasing a FairPhone in Norway.
