    EDIT: sorry, I misread the question
    Yes, I've tried to use a Verizon SIM card on an AT&T phone and it did not work. I'm not sure if it was unlocked.
    I had to buy a carrier-free
    unlocked iPhone 7 to use my Verizon SIM.

    Resurrecting this post as we approach the launch of the iPhone X. I’m a T-Mobile user and was planning on simply ordering the T-Mobile model, but noticed that this model was ONLY compatible with T-Mobile and AT&T, whereas the specs for the Verizon/Sprint iPhone X seem to imply that that model would also be compatible with T-Mobile and AT&T (although Apple is seemingly deliberately vague about this on their website and Apple Store app).

    My question is...should I just order the T-Mobile model and have a phone that will work but will have less resale value later (and wouldn’t work if I decided down the road to switch to a CDMA carrier), or should I order a Verizon or Sprint model and cross my fingers that it will work with my T-Mobile SIM?

    Nice catch in the compatible Cellular and Wireless band section, it does seem to indicate that the CDMA phone has all of the bands necessary for GSM.


    The * Note right before the footnotes seem to indicate that the phone will be software limited to either the GSM or CDMA networks.

    So if I were you I would not risk it.

    I would be interested to hear other peoples opinions.

    You will be unable to get a Verizon phone, unless you have a current Verizon account. Stick to getting the T-Mobile version and don’t worry about the future. If my memory serves me correct, I think you can go into an Apple store and swap a GSM phone for a CDMA one if you can prove you actually switched carriers since part of the benefits of doing IUP is having a truly carrier neutral phone; they do however require ou have a carrier plan when you activate the phone.

    Not GSM. VoLTE as a full replacement for CDMA was a rumor several years ago.

    I prefer GSM. It just opens up far more flexibility in terms of global usage, global devices and SIM cards. SIM cards are glorious things.

    If you don't plan on using a CDMA network then I wouldn't bother trying to get a Verizon/Sprint model. But yes, that model if unlocked will work fine on T-Mobile. However, the CDMA model does give you the flexibility to switch between all the major carriers. Honestly, I would just wait a few weeks for the SIM-free model to release and buy that because the only way to get the Verizon/Sprint phone would be to wait in line at the Apple store and that's assuming they actually have iPhone X in stock. Those are my only choices since I'm on Verizon Prepaid.

    Ok, I will likely just order the T-Mobile model then. I'm planning on paying full price for it directly from Apple, so is it safe to assume that since I'm not going through a carrier payment plan that I can simply swap in my existing T-Mobile SIM card (from my iPhone 6 Plus) when the X arrives?

    Will the iPhone X have a repeat of last year's situation? That is, the CDMA model uses a Qualcomm universal modem, and the GSM-only model uses a less mature Intel modem that may have some performance issues?

    Any idea when the SIM-free iPhone X will release?

    I'm still on an AT&T family plan but would like to switch us to a T-Mo family plan after getting the X.

    I also want to enroll us in IUP for the first time, to get the X (last year I waited for the SIM-free 7+ and purchased it outright for the whole family).

    For a T-Mo plan looks like I'll have to visit an Apple Store in person starting 11/3, which is a hassle.

    Should I just stick with our current AT&T plan to be able to order the X via IUP *online*, then switch to a new T-Mo plan myself afterward?

    Are there any promo benefits to opening a T-Mo plan after buying our own phones (BYOD)?

    Where did you get that information? I am a T-Mobile user and I had no trouble odering a Verizon iPhone 8 from the online Apple Store. I put in my T-Mobile SIM and it works just fine.

    I tried that when the 7 was released. Once you go through all the steps to select the specific phone, it asks you for your carriers, details, number, social, zip code. I guess at this point they connect with Verizon to validate.

    For the sake of testing I just went through all those steps with an 8 (using iPhone app), final step it asked me for my verizon account details. I am assuming when the iPhone X sale begins, it will be the same case. So unless you have a Verizon account, I don't think you can buy a Verizon phone.

    I’m not sure why, but that didn’t happen with my iPhone 8 Order.

    That’s because the 8 is not as popular and was not restricted to you having to be a current subscriber of the carrier in which you ordered the phone for. The X will be like every other flagship phone on launch day... you can pay full price and have it unlocked, BUT you MUST be a subscriber with the carrier you order the phone for.

    I pre-ordered a Verizon variant from Apple Store Online using my friend’s verizon credentials. I guess after reading the thread, i just have to replace the included verizon sim with my own sim and activate the phone with my friend’s credentials, right?

    Activating the iPhone X with my friend’s credentials will not result in deactiving the current sim and service he has it with his current phone since the Verizon activation process is for verification?
