Q: An unlocked Optus iPhone 4s which accepted a Telstra SIM whilst on IOS6 failed to accept the Testra SIM after an upgrade to IOS7. Many visits to the Optus Shop and the Apple Store have failed to resolve the issue.
An "Out of Contract" Optus iPhone 4S accepted and worked perfectly with a Telstra SIM.
Following an upgrade to IOS7.0.4 the iPhone 4S will no longer work with the Telsta SIM.
The following error message is recieved
“The SIM card inserted in this iPhone does not appear to be supported”
Apple Store Genius Bar on checking the 4S iphone in the Apple database indicate that the Service Details Policy is assigned to “Australia Optus (Singtel)” and only Optus can unlock it.
Optus indicate that teh iPhone is unlocked and I have a stalmate as noone is able to advise how to rectify the issue.
A checkof teh Telstra SIM was undertaken on another IOS6 Optus 4S iPhone and it functioned correctly.
I am aware others have had this issue as there is a reference to it on the Optus Support Community.
It means that an international SIM cannot be used in teh iPhone until the issue is resolved
I am of teh opinion teh it is an IOS7 software upgrade issue not a problem with teh harware or the carrier
I await any feedback
Thank you
