''Sim Not Valid'' on activation screen! *PLEASE HELP*

I feel the same way. I lost count of all the misinformation that I saw in this thread e.g. claiming that Verizon's 2320 iPhone policy couldn't possibly include a non-US carrier lock (which it does). And then there was all the talk about "scam sites", when people were simply posting their GSX reports in order to determine the lock status of their phones.

I'm grateful for all the user reports in this thread though, because they pointed me towards the answer for my own iPhone's issue.

The issue here is that all verizon iphone 6's are unlocked for gsm in the us but there are some verizon iphone 6's that can be used internationally but you won't know unless you pay for a gsx report from a third party company. What you have is more than likely a regional locked iphone. It will work with att, tmobile etc but not overseas Or outside the U.S. Apple and verizon don't have answers because they operate in the US and can't tell you why it won't work overseas. Their only business is in the usa. Also if you put a verizon SIM card in an unlocked iphone it will work. My suggestion is to go on e bay and look for verizon iphone 6 unlock service or get an att iphone and unlock it or get an unlocked iphone 6. Don't have apple and verizon running you around and driving you crazy. They don't have an answer for this problem. They will finger point all day. Hopefully this helps. Good luck.

That's VERY BAD advice. I hope no one follows it. DO NOT PAY ANYONE FOR INFORMATION, as there is NO RELIABLE SOURCE of information EXCEPT APPLE. And whatever you do, DO NOT PAY A THIRD PARTY TO UNLOCK YOUR PHONE. All such sites are frauds who will take your money and not deliver a service.

ALL VERIZON IPHONE 6's ARE UNLOCKED WORLDWIDE. If you have one that does not work worldwide there is something wrong with the phone. Either it is damaged or has been hacked or jailbroken.

Alright so I've gone through the same problem though. IPhoneus variant Verizon unlocked not working when using Vodafone sim in india. It's working in Us when using any gsm sim.

So its only Airtel sim In India which is working with iPhone 6 verizon unlocked don't know about other countries.

So if you're in India and have other gsm network then port your number to Airtel which will make your sim work on iPhone 6.

Note:- The reason for the same I was reading somewhere and it says Airtel bandwidth matches the Verizon somehow and all us sim networks when in India takes airtel network to work so this might be the reason.

Hi sushant1727, tried my airtel sim with the problematic Verizon iPhone 6 128GB but it still gives the "SIM NOT VALID" error.

Hi my name is Jared I work for a Cellular compay trying to use vzw unlocked phone and had a customer port there # and I phone 6 into our company from VZW. Before this I had never had an issue activating an iPhone from VZW. This one though gave us this error with the sim not being compatible, which is how I ended up here. After 5 hours of me and my customer sitting in my store arguing with Apple and verizon about the phone being "locked" we came to the conclusion that vzw is right it's not locked and it had something to do with apple. We didn't get a result within the 5 hours. I activated a loaner product for him and he left. He kept calling the next day and finally got a rep that asked him to try this. Take our sim out, goto settings, cellular, roaming, CDMA international roaming (if your having this issue yours is probably on) turn it off and no more invalid sim error. I'm not sure if this is the same situation but it sounds like it and this is the fix!

"As a Verizon customer moving to AT&T, you're in a great position to reuse your iPhone 5S. You should be able to pop out the SIM card and replace it with a SIM card from AT&T or T-Mobile, turn off CDMA roaming, and you should be able to get AT&T 2G, 3G and even 4G LTE service."

What does this have to do with the post I made in January, where I said that the phone had a DEFECTIVE SIM or a hardware problem? I didn't say anything about the phone being locked?

sir Lawrence from what I see, you don't follow the conversation, if we all say that the phone is unlocked in the us and locked for the international don't you think we migh be right? I have the same problem with an iPhone 6 64 gb bought originaly from Apple Store as sim free, I had it replaced one time and now is not working internationally. they still can't do anything so far. and I had this kind of problem before with a phone being looked in USA, I had iPhone 4s bought from sprint with a GSM slot and was not working in the USA except sprint cmda but was working just fine in Europe any network .

While it is technologically feasible to lock or unlock an iPhone for specific geographies phones sold as unlocked directly by Apple are unlocked worldwide. And any replacement for an unlocked phone obtained directly from Apple should be unlocked worldwide. If it isn't someone made a mistake and you should take it back to where you exchanged it. Or call Apple. This also applies to any phone unlocked by the carrier it was locked to.

It it does NOT apply to a phone not purchased from Apple or unlocked by anyone other than the carrier the original phone was locked to.

No. You are not right. That is not how iPhone locking works.

Sprint is a CDMA carrier. For quite some time, it has been Sprint's policy that they will not unlock phones for use on any other US carrier. A Sprint iPhone 4S can not be used on any US carrier other than Sprint. If Sprint agrees to unlock it, which they will only do for a current Sprint customer in good standing, it will only work on Non-US GSM carriers.

If you are not s Sprint customer, you never should have purchased a Sprint phone.

the Sprint phone was just an another example that some phones can be unlocked for some geographic area and locked for some others, that one was old thing and I did not have any problem because i did not buy the phone from sprint to use in any other US network, it bought it to use for international and was working.CASE CLOSED.

My problem from now is that the currently iphone 6 is locked somehow on verizon, this what apple told me and verizon said to me that is not locked on verizon. and now that phone is somewhere in europe and my dad can't use it. probably the only think I can do is to have the phone return to apple and send me a new that is really unlocked for international use. but is gonna to cost me at least 200$ for the shipping back and forth

LTE capable phones sold for use on Verizon are not locked. If you're having a problem using it on a supported GSM carrier, then take it to the genius bar at an Apple Store in the US and have them check it.

Where exactly did you buy the phone you're having problems with? Did you buy a phone in the US with the intent of using it outside of the US?

i bought the phone from apple store, but meanwhile i had water damaged and they replaced me the phone with a phone that is apparently from verizon , phone that worked just fine in the usa with tmobile. but now i upgrade it to iphone 6s and i sent the phone to romania for my father to use it, but is not working.

i did some research and i found out that are other people with the same problem, and either apple or verizon couldn't do anything regarding that.

the fact that is bothering me the most is why in the world i got a verizon phone when i had sim free phone from apple store paid full price.

Look. Verizon phones are NOT locked. Why you believe you have a Verizon phone is beyond me.

What is the EXACT message your father is getting on the phone?
