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

[Ignas Jarusevicius]

Hello Pedro,

I was using Sony Xperia F3111. I have just tried it with Samsung Galaxy
S5 and it registered successfully. I had to manually run if_masq.sh to
get the Internet access on the phone but I guess it is how it is
supposed to work.

Would it be possible to make srsepc also work with Sony phone? 

Regards,
Ignas
