Could the smartcover be causing invalid sim problem ?

I have had an Ipad 2 for approx 6 months and recently had the documented problem of 'Invalid Sim' or 'No Sim Installed'
After reading around, I took it along to Apple who immediately issued a replacement. I asked if it'was a known problem and the girl said that it was.

OK - great so I have a new Ipad to setup.

Talking to a friend the other day , he too had this problem in the UK we chatted together and the thing which we both have in common is that we both use the smartcover.

It occurs to me that perhaps the magnets which affix the cover to the device are somehow damaging the signal slot.
One of the magnets is located directly on top of the sim card.
Anyone good any feedback on this ?
I don't think I want to have the same problem in another 6 months ( when the warranty is finished )
 
My ipad2 is non 3g, but I stopped using my smart cover when I read up a little here on the damage it can cause. One trick a member came up with was to affix some tape to the magnet areas...

As I posted in that thread, I stopped using it before any of the pictured damage. In theory, magnets could have an effect on your sim slot. The only way to test this is to go without it for a while and see if the issue persists. It's not impossible that you got another faulty iPad, and it is a well documented issue as you say.

I don't know why you assert that.
Magnets can cause some very strange things - I recall ATM cards of mine kept close to a PDA in my bag, kept becoming unreadable by the machine.

Unless I can be convinced otherwise, I am not going to use the smartcover.

The purpose really of this post is to try to find others with the same problem and see if they majority are using smartcovers

Probably because I know a little bit about electronics and it seems that you don't. :rolleyes:

You are welcome to believe what you want to believe, of course. Whether or not it's grounded in reality is a different story.

Well maybe its not a magnetic issue. I am having the issue and it appears that the sim cover is damaged from constant pressure from the hinge. I'm thinking that constant pushing motion maybe damaging the sim or sim slot internally.
 
I have an iPad 2, and the sim slot is directly under the articulated part of the Smart cover hinge. There's a gap between the hinge and the sim carrier cover at all times, and the hinge is slightly wider than the sim cover. The width of the gap is about 0.5 mm, so lots of clearance.
