So it would seem that no one else has even posted this online, So i thought i’d create a quick Youtube “How to” style fix video. The iPhone will show a “No Sim Installed” Message like this

The Youtube how to…
I’ve thrown together a small video here for you to watch. Or play using the embedded youtube player below.
Update
This has actually turned out be to quite a popular video, Alot of people email me and comment on youtube thanking me for posting it, So If you have any questions then please feel free to leave a comment.

hi there i got an i-phone from ebay and the imei code is blocked is there any thing i can do ? if not i got buggered over
it an 8GB i-phone and its jail broken already any help would be great thanks alot bud

Gary, there is nothing you can do if its blocked by the Networks in the UK, The only way you will ever be able to use that phone again is outside of the UK. IMEI numbers are at the minute Country bound.
So if a phones IMEI number has been blocked for what ever reason you can still use it in other country. So you might want to sell it to someone abroad, and buy another for UK use.
I hope that help!

Hi Dan,
Jun 27, 2011, 11:12 pmjust to clarify, the two contacts need to be touching when no sim is inserted and not touching when the sim is inserted. That right?
Thanks
Dan Cunningham says:
Hi Ken,
Yep that is correct
Jul 16, 2011, 2:35 amKen says:
Thanks for your reply Dan, I tried both ways but still no luck.
Aug 25, 2011, 1:38 pmI’ll play with it a little more before I throw everything in the bin!
Cheers

Hi Karthi
This is for the iPhone 3GS and 3G only. The iPhone 4 doesnt suffer from this issue.

wat do u do if ur iphone 3g says that the iccid is unknown
Apr 01, 2012, 4:15 amDan Cunningham says:
@Mick : It’s nothing to do with that, Your phone should sync regardless of location Apple dont release country specific updates.
@freedy: Your motherboard ROM sounds like its corrupt. You possibly will need a replacement Logic Board to fix that. (In essence it’s probably not worth replacing as a used iPhone can be cheaper).
