Reply To: ATT flag



ATT = Disable means that the MS is not able to IMSI-ATTACH to the network in this cell. So when someone turns on its phone in this area, its phone won’t attach.
As a consequence, this phone is not reachable if someone tries to call it.
On the other hand, it is possible to make a call. And as soon as the call is being made, the MS becomes de facto attached. Therefore it will be reachable for the next “T3212” hours.
i wonder what “logical” reason you had when you decided to set it to disable, not even knowing what this parameter does 🙂
I’m sure they had very logical reasons to build a nuclear plant in Fukushima…
