[srslte-users] srsEPC multiple SIM with same IMSI

[Ignas Jarusevicius]

Hello,

I have multiple test SIM cards with same IMSI/keys. Does srsEPC support
connection of multiple UEs with the same IMSI? From my initial testing
it seems that the second UE (with same IMSI) is unable connect once one
is connected.

Also, some time ago Pedro sent me a patch to make srsEPC work with sony
Xperia F3111 phones:

However, it is still not in master. Is there a reason why it is not
included? Does it cause issues for others devices?
