As seen here on my blog : http://dancunningham.co.uk/2010/05/30... this is a quick how to video on the no sim problem with the iphone 3g and 3gs - the issue is quite. And my itunes keep on saying there is no sim card installed in the the iphone you are attempting to activate, i been putting a att sim and it didn't work at all and i tried to put a t-mobile sim and that didn't work. what can i do. One of these will be to disable the “no sim card installed” alerts across your ios device. another useful function is to replace/change the “no sim” from the status bar to “no service”. additionally, iphone users can also get a chance to remove their carrier name if they wish to hide it from everyone else..
If you get an alert about the sim card in your iphone if you get an alert that says invalid sim or no sim card installed, follow these steps. make sure that you have an active plan with your wireless carrier.. Iphone, iphone 3g, iphone 3gs: look between the sleep/wake button and the headphone jack at the top of the phone for a slot with a tiny hole in it. this is the tray that holds the sim card. this is the tray that holds the sim card.. The same way. as long as you have a sim card, it works fine..
