HI,

Can anyone help?

When I switched my mobile on today, a message came up saying SIM card rejected. I have taken the SIM card out and put it back a few times but still no joy!

Any ideas, as it was workin perfect last night!

Usually when mine does that just turning it off and on again sorts it. Sounds like your SIM could have become damaged somehow. I'm sure your provider will send you out a new one if you're on contract. If not, not sure really, try cleaning the contacts and get all the dust and crap out of the back of the phone.

the phone could be barred, unlilkely if its yours/has been working fine.

try reseating the sim, swithching on and of.f
