Nokia 9110 6

A quick fix..

This how to get rid of "Insert SIM card" or " Sim Card Rejected"

message and will prevent the phone from turning itself off.

I used encounter frequent 'Insert SIM card' messages appearing on
my phone display and the phone module used to turn itself off.

You can now fix this as it's a very common problem of N9110. It
results from poor connection between battery pins which power the
SIM card and the phone module.

This problem was corrected by the manufacturer in N9110i model, but N9110
users are left by Nokia without any help... Fortunately, this fix is not difficult
and us users can do it ourselves.

All you have to do is to stick a small piece of tape (about 1-2 mm thick) in a
place shown on the picture above, elctrical tape is very good to use.
