I have two FP2 and a AldiTalk/MedionMobile (O2/Telefonica) sim. In both FP2 I don’t get a 4G connection, though the sim works with FP3 and Galaxy S5. I switched Wifi off and did a reboot to the phone. The download speed with 2G is about 20KB/s. The OS is a recent LineageOS.
I got a SMS from the network provider that I should enter a special PIN to the sim to save the configuration, but the PIN didn’t work at all.
it never worked beforce, these phones are new to me.
I think, I tried it at the fairphone user meeting in Hamburg, but I am not sure
I got the first FP2 for paying the postage and the other from @nudge to repair the first one, since I thought the mobile data problem and the reconnects of the wifi would be a general problem in the radio part.
Thanks, that is an important detail.
No, I didn’t think of a SIM card problem till now. Maybe I ask a neighbour for a SIM card.
Well if your SIM fits the FP3 it’s a Nano SIM (4FF), whereas the FP2 takes a Micro SIM (3FF). The FP2 slot being larger, of course the SIM can be inserted but likely improperly placed for the contacts to align correctly. As stated above, an adapter can be used but that’s not advisable.
I would recommend you obtain a new SIM of micro SIM size.
This could always be the point: Use the first, left slot, if it is open, the right one won’t work for LTE. I had the same problem using 2 SIM cards. Both O2/Telefonica, still working today. Only the left one has LTE.
