Q: Is straight talk CDMA 1429 or GSM 1429

The phone sold by Walmart for use on StraightTalk is the A1429 CDMA.

As a rule, you can not use a CDMA iPhone on any CDMA carrier other than the one it was originally sold for.

if the straight talk iphone is GSM A1429 using CDMA 3G netwrok, I can switch to Tmobile LET 4G network when I move. Does anybody know?

I have no idea what you are trying to ask. This doesn't even make sense.

No. StraightTalk does not offer unlocking. The StraightTalk iPhone is permanently locked to StraightTalk and can not be used on any other carrier.

Why don't you just ask StraightTalk?

Well then... if it was on YouTube, it must be true.

KiltedTim,

The reference you give does NOT state that Straight Talk phones are locked. It simply says that Straight Talk does not offer unlocking. Since unlocked phones do not require unlocking, you cannot assume that Straight Talk phones are locked simply because they state they do not offer unlocking. In fact, I just confirmed from Straight Talk that my CDMA phone (which I bought from Walmart) is unlocked.

CDMA phones that are unlocked can be used on any CDMA carrier, although the new carrier has to be willing to physically reprogram it (since there are no SIM cards).

Yes, the Straight Talk iPhone 5 has a nanoSIM slot. If the GSM side is unlocked then it can be used on other GSM systems. If it is locked, like Sprint is, it cannot unless Straight Talk unlocks it.

You are correct there is no CDMA "lock" but for the most part CDMA carriers don't accept bring your own phones.

That is absolutely NOT true. A CDMA iPhone can not be used on any CDMA carrier other than the one it was originally sold for. There is no (legal) way for a CDMA carrier to flash an iPhone to work on a different CDMA network.

Excuse me but that is NOT what Straight Talk says -- they say the phone is UNLOCKED.  Whether the new carrier CHOOSES to flash the phone is their choice but there is NO LEGAL restriction on this for an unlocked phone, CDMA or otherwise (and Verizon can change its policy on this whenever they like).  Furthermore, there ARE unlocked CDMA phones:

This I can take my iPhone to any budget carrier that operates using the Verizon network or to Verizon PROVIDED the new carrier is willing to flash the phone, which, since my phone is unlocked per StraightTalk, they are legally allowed to do.

If you disagree with this assessment, post EVIDENCE referencing a reputable third-party website rather than engage in what now appears to be a deliberate misinformation campaign on the part of you simply because you do not like CDMA phones (which, it should be admitted are more difficult to move from carrier to carrier than GSM phones because they lack SIM card capability).

You don't know what you're talking about.

If you want to take the word of some drone working at a carrier owned and operated by Wal*Mart, that's up to you.

The CDMA portion of the iPhone is NOT unlocked. There is no such thing as an unlocked CDMA iPhone. You don't know what you're talking about. The legal restriction is on changes to the firmware, not whether or not a CDMA carrier chooses to allow you to bring your own iPhone to their network.

Though there are unlocked CDMA phones, there are not unlocked CDMA iPhones.

Isn't it interesting that before you were saying that there were no unlocked CDMA phone but now you admit that there are. Only you still insist that there are no unlocked CDMA iPhones (although it *is* true that you cannot get them directly from Apple, which will only sell you unlocked GSM phones because a CDMA phone, even when unlocked, can only be used on the network [NOT CARRIER] for which it is programmed).  After all, if there were no ability to sell an unlocked CDMA iPhone, Verizon could not offer unlocking now could it, yet it does:

In any case, it is possible to purchase an unlocked CDMA iPhone -- direct from Verizon WITHOUT getting them to unlock it (since it COMES unlocked now):

My point is that if we are on the Verizon network, we can take an unlocked CDMA phone to ANY carrier on that network (though we cannot port them to the Sprint network). Since SmartTalk is on the Verizon network, it matters not (provided the phone is unlocked) to which of the several carriers that sell prepaid on that network I take it (or even if I take it to Verizon). The only question is whether the new carrier will flash it for me.

So stop saying "You do not know what you are talking about." It is insulting and violates the terms of service for these discussion boards. I am more than happy to stand corrected IF you do so in a manner that demonstrates a civil tone rather than beligerance and that is also backed by third-party verification via a reputable website (i.e., not comments from others who think like you do on this website but rather a more official statement).
