I have a fairphone 2 with lineage OS 16. I noticed a problem about using it abroad in some countries (Egypt, Peru, Bolivia, etc.) while it works well in EU. The device cannot connect to any cellular network (2G, 3G, LTE).
Please check your SIM !
Thank you for your fast reply. If I use the SIM from EU country it does not work in that foreign countries. While the same SIM works with samsung s2 and lineage OS 15.1. Is it possible to solve this?
I tried with a local SIM instead of a roaming SIM. In this case the fp2 can use all the networks (2G, 3G and 4G) even if the latter is not listed in the previous Web site.
As I told you the same roaming SIM works well in other smartphone.
What could be the problem?
