Also I noticed this mainly happens the more I wait without making any connection between a terminal and the network, so if I connect the terminal to the network, then wait 10 minutes, and try to execute an USSD code, it is more likely than there is a error establishing the connection.

This sounds like the time I was using a B210 without a solid external clock.
Randomness to the point of sometimes seeming reliable.

Funny part is, it didn't get better when I connected a GPS antenna.
Then learned that the B210 had only the external connector without a GPS receiver inside.

Connecting the 10MHz external oscillator made things work nicely.
(Or a sysmoBTS also does.)
