[srsran-users] COTS UE does not see the corresponding network

Hi all,
I run sudo srsepc and sudo srsenb, the eNB and ePC are connected but the corresponding network cannot be found using COTS UE (Samsung Galaxy Neo 3). I am aware that the phone I used supports GSM900, so I have used the DL_EARFCN in the range from 3450 to 3790. I have changed the value of DL_EARFCN but it does not work. I have added the APN to my phone (according to here<https://docs.srsran.com/en/latest/app_notes/source/cots_ue/source/index.html#cots-ue-appnote>) but still couldn't see the network.
My setup was listed as follows:
1x Raspberry pi as eNB
1x laptop with ubuntu 20.04 LTS running ePC and remotely controlled eNB via PUTTY
1x USRP B210 connect to raspberry pi
1x COTS UE (Samsung Galaxy Neo 3)
The screenshot of EPC, eNB, USIM card details and configuration files are attached.
I hope someone can give me a solution to this problem. Much appreciated if you could provide me with a solution.
Thanks.
Seah
