Hi @dkwene ,
Try starting the phone in [https://support.fairphone.com/hc/en-us/articles/217869383-How-can-I-reboot-my-FP2-in-Safe-mode-|safe mode] to see if perhaps a downloaded app is causing the problem.
Take heed of the "''Please Note''" near the top of the page.

+Hi @dkwene ,
+Try inserting a different known working SIM card which uses the same network provider as your SIM cards and see if it works OK. Check if your card(s) work in a different known working same network phone. Basically swap SIM cards between two phones.
+If it still doesn't work try a [https://support.fairphone.com/hc/en-us/articles/115001610926-How-to-return-to-Factory-settings-on-my-Fairphone-2|factory reset] and then check if it works OK.
+''Be aware that a factory reset will erase all your data and downloaded apps, it will restore the phone to its' factory default condition. It will be like when you first bought it.''
+Before you perform a factory reset, '''backup the phone first''' using the phone's backup feature. That way if the reset solves the problem you can restore the phone, with all your data etc, from the backup that you made, using the phone's restore feature.
+If it still fails after the factory reset, then the phone is faulty.
+As it is new, consult the ''manufacturer's warranty'' statement, usually found with the documentation that came with the phone or in the User Guide as to what you have to do to make a claim for a manufacturer's warranty repair, replacement or refund
