Recently I retired my old iPhone 4 (running ios 7.1.2) và decided I would give it to lớn my brother lớn use as a glorified iPod touch. So I connected it to lớn iTunes, mix it lớn restore, & gave it to lớn him, and he connected it to his iTunes. It came up with the usual thiết đặt sequence, but came up with the message asking for a SIM card. Being a CDMA model, it doesn"t even have a SIM card tray, so I am highly confused, and can find no way around it other than jailbreaking it. Any help is appreciated, I"ve never had this problem before after restoring it.Bạn sẽ xem: Iphone 4 cdma hà nội

User profile for user: caseycat0221Unfortunately I"m unable to restore the phone from a backup, as every time it"s connected lớn iTunes, the phone & iTunes both come up with the same message about the SIM card. I would try to put it into Recovery Mode, but the lock/unlock button is broke & I cannot power the phone off, so I"m waiting for the battery to lớn run down. If Recovery Mode doesn"t work, I"ll have no other option but to tương tác my carrier.

There is a post not that much further down the page dealing with & listing exactly the same issue that you have - namely that when the phone is restored, it will keep asking for a sim card to be inserted into the phone & of course a Verizon CDMA iPhone 4 does not have a sim card tray.
The OP on that thread tried contacting Verizon without much luck, but thegioinghiduong.com is apparently aware of this fault, so you need to liên hệ thegioinghiduong.com tư vấn regarding the issue & you need to talk to a senior thegioinghiduong.com engineer to lớn fix this issue.

This is a problem of Verizon"s. They pushed a carrier update khổng lồ all Verizon phones, including those that vì not have SIM slots, lớn unlock the GSM side of the phone. You need to gọi Verizon, possibly escalate the problem lớn tier 2 tech support. Although by now, 2 months later, all Verizon CSRs should know about it.

But my phone wasn"t through Verizon. It was with a smaller company. I did contact the carrier. They said they could unlock it but couldn"t help me with this issue.
That"s the first case of heard of this issue with an MVNO. Call your carrier & explain lớn them what I posted. The will have to contact Verizon.
I FINALLY got this issue resolved. I kept getting the message on my phone and in ITunes. I got thegioinghiduong.com lớn speak khổng lồ me without having to lớn pay the fee. The rep told me he has seen this a few times in the past. There is something they have to vì chưng on THEIR kết thúc in the software to update the older phones so that it stops telling my Iphone 4 to lớn insert a sim card.
But there were still issues. He said that I had to vị the update/restore because the phone was unlocked by the carrier và when it tried lớn update/restore I got that message. So, when the engineers fixed it for me, the new update RELOCKED my phone. They tried to lớn unlock it again (the rep said he has never seen them offer lớn unlock a phone before but since their software was what locked it again they would). So, when I had lớn restart again I got the sim card required message yet again. So, another ticket put in by the rep & they tweaked the update, restored, & the sim thẻ message went away but the phone was locked...yet again. This extremely nice rep kept calling me back with updates all day long trying lớn fix this issue. Anyway, after his last ticket that went into great detail the issue I was having the engineers let him know that the older CDMA phones can NOT be truly unlocked. Even though it said unlocked on their system and was "unlocked" by the original carrier for me, it was international only (he said most people don"t know that). But, within the US I was still locked lớn the original carrier & they would never be able to unlock it so that I could get service through another carrier. If they try I will get the "sim thẻ required" message each time. He said jail breaking wont" fix it either since that is to just unlock features và not carriers. He informed me that newer cdma phones can be unlocked because they use GSM as well as CDMA but older ones will always be locked to lớn the original carrier no matter what they do. So, my older phone is only useful for camera và wifi stuff. It can never be used as a phone unless I go with the original carrier which doesn"t even have service in my area. Wish I had known that before I bought the straight talk activation kit for $70 which is non refundable even though straight talk assured me it would work (I talked to them before I purchased it but they still won"t give a refund).
