Why would a factory-unlocked Iphone get an invalid SIM error?

I bought 2 unlocked iPhones to sell overseas and they are giving an invalid SIM error. Both of them are the factory-unlocked version. Could someone help me with this?

Positive that they are unlocked. I bought them personally at an Apple Store and the invoice says unlocked iPhones (I also paid the unlocked iPhone price).
The Cell Service Provider has iPhone as one of its supported phones. Not sure exactly which MicroSIM the person is using though.

After upgrading to iOS 7.0.6, I get intermittent "invalid SIM" error.

After upgrading to iOS 7.0.6, I get intermittent "invalid SIM" error where the carrier strength (top left corner) should be.   Of course I loose all data and cellular connections at that time.   The only workaround is to power the device off and back on.   I have to do this at least once every 2 or 3 days since the upgrade to 7.0.6.   Anyone else having SIM related errors since the upgrade?
This happened once before when I first updated to iOS 7.   The next patch that Apple sent out resolved the issue, and I haven't seen it again until now.
I hear 7.1 may be coming out as soon as next week.   Any chance this issue is resolved in that release?

Thanks for the input. That link shows steps that I've already taken. I know it sounds weird, but I believe it may be software related. Like I said before, this happened once before when I first upgraded to iOS7.   I lived with the issue, having to reboot the phone every couple of days, until the next update from Apple. Once they sent out the next update, the problem went away.
If it is not software related, then it must be a corruption of the software download and installation. I did it over the air. Possibly downloading whatever release comes out next will fix it because it's a new installation. The software itself may not have the fix in it, but the act of downloading and installing the new software may fix it. Just a thought...

I keep getting an "invalid sim" error on my 4s!

Just received my new AT&T phone today. Set it up with no problems. Then I get an "invalid sim" message. After rebooting a couple of times it goes away, but it keeps coming back. Thoughts?

I found that if you remove the SIM card, reseat it in its frame, then reinsert it, it seems to solve the problem.
Turn off the phone.
I got a paperclip and popped out the sim card by putting the end of the paperclip in the tiny hole on the side of the phone (its on the opposite side of the volume controls). This will pop out the sim card.
Take the sim card out of the casing, blow on it for good luck, then place it back in the casing.
Push the casing back into the phone until it snaps into place.
Turn the phone back on.
It's been 24 hours and haven't had any issues since. Hope this saves you from standing in line at the Apple store....

Why does my factory unlocked iPhone say 'Sim is invalid'?

So i restored my iphone and it all of a sudden would not let me activate it and would tell me my sim card is invalid? after it's been perfect for months. so i go to the apple store and the employee replaces my iphone and tells me to order a new sim card. so i do just that, and with the new phone and the new sim card it still would not allow me to activate my iphone, and it comes up with the message 'sim card is invalid' I really am so frustraded because it has been a week without my iphone and it's really not the time for it to shut down on me. -help would be awesome.

I would take it back to the Apple store. Maybe the replacement wasn't an unlocked phone.

How do I get a factory unlocked iPhone 3GS out of (connect to iTunes) mode?

How do I get a factory unlocked iPhone 3GS out of recovery (connect to itunes) mode?
Once the iPhone 3GS is in DFU mode and plugged into iTunes, the restore and update process begins. The restores process are as followed:
Extracting software > Preparing iPhone for restore (blank screen) > Preparing iPhone software for restore > Restoring iPhone software > Verifying iPhone restore > Restoring iPhone firmware > The iPhone cannot be restored. An unknown error occurred (1).
I clicked on the more information tab and was taken to a website with some troubleshooting. I did what they suggested (based on the error #) and still no luck. I’ve tried to restore and update about 10 times now but the same message keeps coming up at the end. What should I do now?
P.S: I have the latest version of iTunes (11), my windows is up to date etc ...

If you have a beta copy of iOS6
1. You are a developer and will know how to transition from beta
to release version and to use the Develpoer forum
2. You have a pirate copy of the beta and no-one on this Apple hosted Forum can help you

Why factory unlocked iphone require Sim activation ?

I have Factory Unlocked iphone 4, why required sim activation ?
Iphone was on OS 5.1 I upgraded on 7.1.2, first of all the Update failed in start then I had no choice but to restore and now it requiring sim activation, well it's non contract Phone why it need stupid sim activation ?
Why the update got failed ? Steve Job's dream was every hand should hold iphone (We'll provide best of the best) but looks like it can not be accomplished without him (that's my opinion, no offense).
Let me know what is the solution for that, I don't want to install the CYDIA on that like everyone else.
Regards,
M.Aqib

You mean any Sim could be used for activation ?
I unlocked it through at&t website, I am having a legal Phone
I have updated it for the first time.
Mentioning Steve Jobs means he cares about his customers, I don't know about the rest nor I see (again it's a opinion nothing personal).
About the Jailbreak I am not impressing anyone nor I need to and it's not a threat it's a solution I got when I Google it and saw couple of videos on Youtube, it's not something I have said, I said I don't want to do it if you have read my post properly.
You can't OBLIGATE customers like this, show a bit of professionalism.
Looks like you have taken this a bit personal. Customers use this forum for help not to be disrespected. That's not the way Apple should treat it's customers.

Will Apple cover my factory unlocked iphone 3GS anywhere in the world?

Hello,
I'm planning on buying a factory unlocked iphone 3GS directly from the Apple Store in Hong Kong.
Will Apple cover my iphone with the warranty worldwide or only in Hong Kong?
Thank you.

What I meant to say is that technically, hardware-wise, almost all iphones 3GS are the same (I believe the models in mainland China don't have GPS?).
It's no WiFi in China. GPS used to be illegal in Egypt, but they changed the law recently.
Correct me if I'm wrong but I suppose that the carrier lock is a software lock, which can be removed (we've all heard about it), but gets reversed once you update to a new OS version.
Carriers can ask Apple to unlock particular phones. The next time the iPhone is restored via iTunes, new firmware will be downloaded from Apple and will display a message saying it has been unlocked. It will stay unlocked if updated. Unofficial unlocks (which can not be done on current iPhones) will re-lock if the iPhone is updated.
I know it is the way it is, but I believe most of you would agree that if you buy a telephone, you shouldn't be forced to go with one carrier or another. That is why when I pay for an unlocked phone, I pay much more, go get the freedom (without hacks) to choose the carrier I want (where in contrast I pay much less for calls and internet than with the exclusive iphone carrier).
It would be much easier for Apple if all iPhones were unlocked, and the same in all countries, but the carriers make a fortune from their exorbitant roaming charges, so where the country's laws allow, insist that Apple not make any unlocked iPhones available in their countries.
By the way, MMS is not something most people use. There are some statistics on the internet about the ratio of SMS to MMS and it was something like 10 to 1.
All the 3G and 3GS iPhones are capable of MMS, but the carriers have to support it.

Factory Unlocked iPhone 3G giving "No Signal" woes

My iPhone 3G is from Italy - factory unlocked. Confirmed by iTunes when doing a restore.
Any UK SIM (o2, Vodafone and Orange) I put in the phone shows "No Signal" unless I am right underneath a tower. BUT, if I put my Malaysian SIM in the phone and run roaming with Maxis I get 4-5 bars everywhere - get that!?
Is it a SIM thing - i.e. different technlogy of SIM cards ? I notice the Malaysian SIM has a smaller active area than the UK SIMs.
Or is my IMEI or ICCID profile somehow blocked b he phone or the phone limiting the juice to he antenna for some reason with a UK SIM.
Running 2.2.1 and 2.30.03
Any advice or next steps I have run out of options.
many thanks to those that can contribute.

Allan
Your advice is about all I can think of doing. I have a friend in Milan that the phone can be sent back to. I have a funny feeling that when I get the phone back I'll have the same issues.....
I can get a antenna replaced here in the UK for about GBP60....but that would invalidate the warranty.
What is a lingering doubt over it being a hardware issue is why would it work perfectly with one contry's SIM and not anothers ?

Problem Factory unlocked Iphone 4s

Hello! Need help , I recently bought an factory unlocked iphone 4s from USA apple store, and only after 3 weeks it's not working. Problem is I'm in Europe , and I've spoked in Germany on customer support about my problem and they advice me to come in an apple store in Munchen to see the iphone ,
after arrived in apple store they had checked the device and told me that is true there is a problem with this and they have to change the iphone!
After the come with a new iphone they told me they cannot change the device beacause it is buyed from USA , and they don't have the code in the system for USA iphone!!!!!!!
It is possible something like this?
It is a stupidity in my opinion!!!!
Why they are official apple store? Why we have international warranty ????
It is not my problem they don't have the code in the system ...
How can I solve this without going to USA ?
Thanks

The warranty is not international. This is not new or unkown.
You would have to get the iphone to the U.S to get warranty service.
This is why it is advatageaous to get the iphone in your country of residence.
Sorry.

T-Mobile SIM card won't work with my replacement factory unlocked iPhone 5

On Saturday, my rear camera on my factory unlocked iPhone 5 stopped focusing. I took it in to my nearest Apple store and they replaced it. Problem is, now I can't get my T-Mobile SIM card to work with the replacement phone. The guys at the genius bar sent me to T-Mobile to see if a new SIM card would fix the problem, but I'm still getting an "Unsupported SIM" error when I try to activate the phone. Any insights?

Do you have information about the model no. of original purchase that is printed on the back cover ?
What is model no. of the replacement iPhone 5 ?
If T-mobile SIM worked on the original purchase and does not work on the replacement iPhone 5, they gave you a wrong model.
