1 year ago can you expound for me how you managed to connect the phone and which programmable sim you used.
otherwise i am also facing a syncronisation issue : and i can't attach it to the network
the srsue log file looks like this

Issue Description
I am trying to establish end-to-end 4G network and I have encountered an issue with SFN synchronization running the UE. After the message that SFN is not yet synchronized I get the message about SNR and RSRP status.
Setup Details
The setup I’m using is : 2 PC + 2 bladeRF -> 1st PC – running the UE -> 2nd PC – running the ENB and EPC in separate consoles
Expected Behavior
I want to connect the 1st PC to 4G network of the 2nd PC.
Actual Behaviour
UE Synchronozation error message [PHY] SFN not yet synchronized, sending out-of-sync [PHY] SNR = 2.3 dB RSRP = -86.8 dBm, sync=out-of-sync from channel estimator
Log UE :
Log EPC :
Log ENB :
Steps to reproduce the problem
I have tried to change different parameters in ue.conf file testing different tx and rx gains but without success. Also I put the same usim informations in user_db.csv file and I named the APN the same way in ue.conf and epc.conf file. I have ip_forwarding activated on both computers and I switched cpu on performance mode. I’ve tried to use srate=11.52e6 in ue.conf file but it gets even worse. Here are the pictures of my logs and ue.conf files.
UE.conf file :
Additional Information
Before using 2 bladeRFs, I managed to connect to 4G network using a cellphone Pixel 6 with a programmable sim as UE, so the problem is probably in my UE.conf file.
