View Full Version : iPhone 3G intermittently losing sim??

16th August 2010, 05:59 AM
I recently bought a 3G second hand and it worked a treat. However, since upgrading to os 4.0.1 it occasionally loses it's sim card- I get a 'no sim installed' notification. Only shutting down and redrafting the phone will bring it back. It is a pain because sometimes it goes without me noticing. Could this be the os itself, or perhaps an app causing it to play up?is this a known bug?

I get this too... It's *really* annoying. I've had a perfect phone for almost 2 years, but since upgrading to iOS4 it's been appalling.

Try a SIM swap.

Get some compressed air and blow some air out of the SIM card slot.
