I've had my iPhone 6s with Verizon now for almost 2 years now, I'm guessing 2 years because I have only one payment left on the phone. Anyways, **my current 6s is the A1688 model**. The screen has a little crack, sound issues, etc. I found a refurbished 6s on Amazon for a decent price I think.

I ordered it from a 3rd party seller but it was fulfilled by Amazon which helps if you ever run into issues. Anyways, I got it today but it says A1633 on the back. I have no idea about phones not tech savvy, but what is the difference between my current 6s A1688 & the 6s A1633 they sent me incorrectly?

For example when I bought the 6s it said this "Apple iPhone 6S 64 GB Unlocked, Space Grey $349".

Also, the page said it was Fully Compatible with Verizon Wireless as seen in that chart & this one. Now when I go back to the order, when I click on it, it now says Apple iPhone 6S 64GB Space Gray - GSM unlocked. I thought GSM is T-Mobile/AT&T, so I'm confused?

Will this A1633 work on Verizon & will their be any difference with that phone vs my current one? I just wan't to make sure this phone that this new phone will be taking full advantage of the Verizon network.

Also, I just turned the phone on, I can't get passed this:
SIM Required: Please insert a SIM card.

Why can't I just get to the home screen, why am I stuck here? I swear, if I remember correctly, when I got my A1688 model you where able to set up your iPhone with just WiFi, I don't remember seeing any SIM card screen that prevented me from going to the home screen?

Thanks for the help & my apologizes for the long thread I just wanted to make sure I'm doing this right. Keep it, return it, etc.? By the way, the 6s they sent me has no cosmetic flaws.

Go to this LINK which will explain the different model numbers and which networks they work with. Also, I do believe you need to insert a SIM to set that phone up. I've never been able to set a new iPhone up with WiFi only.

It is possible, I've done it on my SE and my 6S. But you do need the sim to get the phone activated on a network.

The A1633 is the version Apple sold as the SIM-Free 6S. It will work totally fine on Verizon as it’s the version that works on the most networks.
