VERIZON SIII: Can I use this phone with a GSM carrier, or is it only CDMA.

Hi, I noticed that the Verizon SIII has a SIM card slot on the back. My question is, can I use this phone (verizon version) on AT&T network or T-Mobile using a SIM card?
Thank you!!!

This is not the Verizon SIII forum .

[Q] verizon galaxy s3 on tmobile network help

Hi guys, so my mom has her gs3 on verizon and she bought a sim card for tmobile. We activated it and we get Edge data speed but nothing more. We live in a LTE area with great service but we just have edge. how do i get her data to LTE or HSPA+? Also when entering *#*#4696#*#* i dont get the option to change the LTE/CDMA radio like i use to

The vzw gs3 is not compatible with T-Mobile. Be glad you get edge
Different radios in the devices.

+1. Edge is all you can get with any non Verizon US carrier.

Verizon SIM Card in US Cellular SIII?

I accidentally bought a US Cellular Galaxy SIII brand new. But turns out, there is no coverage anywhere close to me except for Roaming on Sprint. So can I activate A VZW sim on a broadband plan for a galaxy tablet and then put it in my phone? Can a cricket 4G sim work in it? It is a CDMA phone that takes a 4G sim and I really want to use it.

[Q] Verizon s3 sch-i535 4g lte work with singapore singtel sim?

I recently found a phone at the bus stop and it is a verizon s3 sch-i535 4g lte. The whole SIM card and memory card holder was removed. I am wondering whether my singtel(singapore carrier) iphone 5 4g lte will work in it? Because if it does, I wouldn't mind spending a couple of bucks getting it fixed. Please let me know if it will work or if I can do anything to make it work. I live in singapore.Thanks

Using cricket sim on device?

I have a straight talk S3 (Verizon based) and a cricket sim card. How do I make the cricket sim work in the phone?

You need a CDMA SIM from any CDMA carrier and it will work as soon as you put it in, then you set your APNs to Tracfone APNs.
If your Cricket SIM is a GSM SIM then it won't work, it MUST be a CDMA SIM.
Verizon CDMA LTE SIMs are only $3-5 on eBay. I'm sure you can afford the price and the wait while it is mailed to you.

I used a friend's Verizon Galaxy SIII at one point... kind of... it took a while to detect the network each time the phone started up and it was only EDGE/2G
So, it works for phone calls and very slow data... might be okay if you're usually on wifi, but it's really better to just have a phone that is compatible with Cricket's HSPA+ 3G and 4G LTE network(s).

They are asking about the SIM because they have a straight talk s3 and that device has to use Verizon S3 ROMs and that makes the Straight Talk S3 require a SIM to have working mobile data, it won't work without the SIM. They weren't asking if they can use a Straight Talk S3 on Cricket network.
