| | Sporadic "Invalid SIM card" error
Please Login to Remove!
Hello to all,
my BB (which I love so much) lately gives me a problem I cannot solve so far.
From time to time it would just stop receiving calls, emails and everything else and display "Invalid SIM card" error. In the beginning I would just switch it off, remove the battery, put it all back and turn it on again and everything was fine again. But lately this is just happening too often.
I have tried with brand new, different, battery - problem is the same.
My provider - AT&T, this is the original phone, hasn't been unlocked, there was no need since I use AT&T network. The phone works fine when there is no error and I am very sure this has nothing to do with locking/unlocking the phone (I have googled and searched - this forum as well - and always got the unlocking as solution which is not the case here).
AT&T help desks was unable to help with this.
Please help. Thanks.
