9900 'Insert Sim Card'

Hi I've got a 9900 which i haven't used for around 4 months.


Noone has used it since then, when I got it all i done was upgrade it to the latest os.


Now when I try to put in any sim, it doesn't detect it. I'm not sure what the problem is.

Re: 9900 'Insert Sim Card'

Hi and Welcome to the Community!

Here is a KB that discusses that error:

  • KB10824 Insert SIM Card, or Data connection refused

Hopefully it contains something useful! There also are multiple existing threads on this site that discuss that exact error...your review of those might prove useful, and a search of this site, using the error message, error code, or symptom, should reveal all applicable existing threads to you.


It is also possible that the SIM card has gone bad...you should talk to the provider of the SIM card to be sure.

Good luck and let us know!
