[srslte-users] srsEPC: UE unable to register on network

[Ignas Jarusevicius]

Hi Pedro,

Thank you for looking into this. I attached enb.pcab together with
enb.log and epc.log from the same run.
The APN settings on the phone are:

APN: srsapn
Proxy: not set
Port: not set
Username: not set
Password: not set
Server: not set
MMSC: not set
MMS proxy: not set
MCC: 001
MNC: 01
Authentication type: none
APN type: default
APN protocol: IPv4
APN roaming protocol IPv4
Bearer: 4G
MVNO type: none

I have tried changing APN in epc.conf and on the phone but result was
the same.

Regards,
Ignas
