Hello, I have a Nokia 6101 and I've twice experienced an incredibly
annoying problem with it (to use mild words).
I did a good search with google but I didn't find anything. A perusal of
Nokia's web site and forum didn't help either.
First of all, I must say that the phone was originally bought in Italy
(from Telecom Italia Mobile) and then moved to England, where I'm using
it with Orange UK. I exchanged the SIMs and it worked fine at once
(i.e., the phone is unlocked), so I assumed everything was OK.

The problem I mentioned is as follows: the phone appears to work
normally and reports good strength for the signal BUT if people actually
try to call me the phone doesn't ring at all and (so I've been told) is
seen as switched off.
Furthermore -- and even worse -- apparently they are also unable to text
me (the text is somehow rejected, I don't know the exact error message
other people get). Also, if I try to call or text someone while the
phone is in this zombie state it doesn't work (sorry I didn't write down
the exact error message I got).
In fact trying to use the phone is the only way of knowing that
something is wrong. I've been using this phone for about a month and
this thing has happened (as far as I know!) twice, once just a few days
after I first got the phone, and the second time yesterday (which caused
an untold amount of distress as I was waiting for an important call).
Switching the phone off and then on again solved the problem in both
cases, so I assume is some sort of firmware problem, possibly a minor
incompatibility between my phone/firmware and Orange Uk.
Has anybody come across a problem like this? What should I do?
Any feedback would be very welcome, because otherwise I'll have to do
sample calls every 15 minutes just to check that the phone is working
properly!

This are the details of my firmware, as given by *#0000#:
