I boought my iPhone 5 direct from the apple store on a post paid Optus plan. I have followed the advice on this site to restore the iPhone but it remains locked to Optus (activation server states SIM is not valid). Apple say only Optus can help. How do I unlock the phone if a restore and the current update isn't working?
Solved! Solved: Go to Solution.
Hmm it shouldn’t be locked as my old iPhone 4 required nothing more than syncing with iTunes before the new carrier sim would work. Not sure what IOS version you are using however the later versions required nothing more than a restart with the new sim in place. You may need to do a factory reset if you have problems with the update.
Edit: How long ago did you buy this phone?
Phone bought in Nov. 2012.
I have performed a factory reset by using the erase all content and settings from within the phone. Did not work. Then did another restore (not from a backup) and still get the SIM NOT VALID error. (carrier not supported, etc). Did one more restart just to be sure but still locked out.
Hmm the message you are getting is not what I recall however it has been a few years since I have messed with iPhone sims. Have you got a spare sim you can try in the off chance that it’s a sim related issue? You can get a $2 blank sim from the post office or many supermarkets and such if you don’t have one.
Hey @WillSith in some cases the IMEI has to manually unblocked. PM me your mobile number, full name, DOB and the IMEI and I can request this for you. Gen
The manual reset at the Optus end worked, Gen_R got this done in minutes....excellent response!
Warning to others, I didn't find this problem until I travelled overseas and tried a local non-Optus SIM even though all the info I read before my trip assured me it would work if it was updated to latest software version. No mention that "some" may need a manual reset. A very expensive and time consuming problem when trying to fix on the other side of the planet!
All good now though.
Hi Gen_R and WillSith,
I've reading through your posts, and I believe I might have the same problem as the one WillSith mentioned in this post. I got the exact same message as WillSith I.e. Your phone is locked..... activation code.... etc. I chatted with Apple, and they suggested and I performed the following; Factory reset (erase all settings), updated device to the latest iOS, and restored the phone via iTunes. Still the same error message appears. I checked with Apple and they said that according to their records Optus had already unlocked the phone. Like WillSith I too just discovered this when I went overseas (now in Vietnam), as an Australian Vodafone SIM card strangely worked fine.
I would greatly appreciate any advice or assistance.
Thanks in advance
@Steve1980 More than happy to help you out with this one. Can you please send us a PM with your mobile number, full name and DOB? Shauna
