CDMA phones only have a SIM card for when they're running on a GSM network. I.E. overseas.

How come Sprint doesn't use a sim for their LTE? Is the sim even necessary or is to bring global usage to the Verizon version?

The SIM card is used for 4g. 3g and voice is over the cdma radio. And sprints does have a SIM if I'm not mistaken it's internal tho and cannot be accessed.
The biggest problem with the "non-removeable" sim setup that Sprint uses is you can't just pop it out & stick it in another phone.
I do this all the time with my VZ sim card.

thats for sprint? it looks like verizon its all handled through the sim for both lte and 3g.... right?
As far as I know its just the lte that needs the SIM. Now of course the phones are made to not function w/o them but I'm pretty sure it's only the 4g that actually relies on it
I just bought a Verizon GS3 on craigslist, but it didn't come with a sim card and in my ignorance I didn't know it needed one. I don't have a verizon account and I want to use this phone on pageplus. So is a sim card necessary, or can I get a sim card somewhere without having a verizon account?
It's an LTE sim card. Not a true sim card. It's still a CDMA phone.

Sorry for my ignorance, but I have no idea what this means. Can I use this phone without a sim card in it on pageplus?

I'm not sure if pageplus uses sim card or CDMA phones. For example, at&t is all GSM (sim card), their phones won't work on Verizon (CDMA) and vice versa.

Pageplus is CDMA, it uses Verizon's network. Without a sim card in the phone it doesn't seem to be able to find a network...but what do I know

You can have this phone on gsm. If you put a normal sim into the lte sim slot you can use other networks. The downside is you will not get 4g or in some cases you wont even get 3g.

So you can 'technically' have it on gsm.

Hello, It is my understanding that Verizon phones are unlocked. have an HTC One phone that I would like to switch from Verizon to ATT. When I put a new sim card in the phone, it seems the ATT network is being blocked. Any thoughts?

Vezion is a CDMA provider which does not use sim cards (only mini sims i think for specific devices) while att is GSM which uses both mini sims and regular sims.

Thank you for your response. The HTC One has a mini sim card. I have an AT&T mini sim card to put in the phone, but when I do so it doesn't recognize the AT&T network and the CDMA/GSM setting is blocked. There is a way to switch networks. Could someone please help me out in identifying how? Thank you for your help in advance!

Verizon LTE phones are all sold unlocked and use sims. Also every model that I can think of sold in the last couple of years has GSM bands to be sold as "world phones". I appreciate the attempt to be helpful, but spreading misinformation is the opposite of that. After some more trial and error, it was an ATT provisioning issue
i bought a Us Cellular phone off ebay and since it has a sim card slot, i assumed it would work with my gsm sim card. it didnt. my question is that is it possible to flash it from being cdma to work with a gsm sim.
Hi, thank you for using XDA Assist. Generally it is not possible. Whether it is cdma or gsm is hardware dependent.
im new so im wondering how to change to sprint on cdma phone
Buy sprint SIM card?

Dude you know what CDMA is all about?!
If You have sim card just enable CDMA in phone settings, set your network to 3G (band 1900)
