3510i simcard rejected problem

[szergej]

I've got a problem with my (new) 3510i. Sometimes (usually after outgoing calls) it writes "Sim card rejected". I turn it off then on again, and it works well again.
It does this about once a day.

Why can this be?

"sim card rejected" message is displayed when
you type the wronk PUK code 10 times.
or
when there are problems with the contacts of the sim.

make sure the contacts are clean, and the simcard is in it's place touching the contacts.

if the problem still exists - replace the phone. the warranty covers such problems.
