Hi Neels,
Looking into your configuration, I managed to start sgsn,ggsn,nitb and pcu
without error. However, When I look into the pcu running configuration I
see that there is a different configuration from the starting one ( no
egprs ), is this normal? I changed it to egprs. Another issue that I faced
yesterday, was that I could connect my phone to the network (this one time,
today I was trying to connect but it didnt connected), and the symbol of
GPRS appeared, but couldnt make a ping to 8.8.8.8 for example, even after
doing the nat masquerade thing.

I see in the vty sgsn that my phone does several routing area update, but
does not connect. what it could be?

Here is my configuration attached, I am running everything on sysmo2050.

Best,
