Verizon uses a CDMA network. ATT&T uses a GSM network. They are two totally different systems. Devices from one can not work on the other.

i know but usually you can unlock phones and i was wondering is rooting also unlocking your phone
A rooted phone is not the same as an unlocked phone(which can only be done legally by the carrier, at least in the US). A rooted phone is giving the user access to the phones system which is normally blocked. An unlocked phone is a phone not tied to a carrier(Verizon, Sprint, Att&t, T-Mobile). You can still buy an unlocked phone but the process of unlocking a phone is now illegal in the US. It can only be done by the carrier.
Even if a Verizon phone were unlocked it can never be used on Att&t because they are totally different technologies. Technically a Verizon phone would work on a Sprint network but there are other issues which don't make it really possible.

A buddy of mine has a Droid 2 Global as a personal phone and an AT&T crackberry from his employer. With a turbo sim or other unlock method is it possible to be on both networks at the same time with the D2G? He wants to be able to receive voice calls from either network and use Verizon for his data. He's just sick of having to carry around 2 devices when oncall.
I've already got him rooted and on Fission, but I'm not very familiar with this device as I'm an Epic user.
No, you can only use CDMA or GSM, not both at the same time.

And even if you could, Verizon locked out all US GSM carriers.
Is it true I can simply put an at&t sim card in the phone and use a dumb phone plan if I buy an unlocked ones? Also does it get at&t 3g?

Besides SIM unlocking you need to perform the US band unlock as described both here, on Rootzwiki, and who knows where else, to use the DROID2 GLOBAL on AT&T or T-Mobile.
As AT&T uses standard WCDMA bands, yes, it will work with their 3G voice/data network as long as the band unlock hack is in place.

Thanks I couldn't find any posts that were newer than a year ago. Now to find someone selling one here with everything done.

I doubt there are a lot of band unlocked D2Gs on sale as reflashing the SBF image breaks the hack.
You can perform the hack yourself provided you buy a SIM unlocked device.
Refer to http://forum.xda-developers.com/showthread.php?p=22769743 for instructions. Do note that whenever you soft-brick your device you will need to SBF back to 2.4.x and apply this hack.
Remember to never ever update the device to 4.5.629.
Thanks. Hopefully I get lucky but its Greta to have that link

Dumb phone plan from who? If you get everything done (band unlock as described in the other posts) you can use your phone with an AT&T SIM and don't need any plan at all from Verizon. Is the theory that AT&T won't recognize it as a smart phone because it is not one that they ever sold?

I guess so. I found a list of every phone that works for att dumb plans and it was on it.

Any non-carrier-locked GSM phone that has compatible bands can work on AT&T's network. You don't even need a list, just check which bands AT&T uses and check the phone's tech specs.

I think the problem is that people don't want AT&T to recognize the phone as a smartphone and helpfully add on a data package on postpaid plans, (presumably these people are intending to use Wifi for data). The claim was made that some people had moved a SIM from dumb phone to a smartphone purchased elsewhere, and suddenly they got billed for a data package. See, for example, http://www.zdnet.com/blog/bott/can-at-t-really-add-a-pricey-data-plan-onto-your-wireless-bill/2667
In the past, there were posts saying that you were "safe" if you used a model that AT&T had never sold, as their system would not be able to recognize it as a smartphone. Not sure how true this really is!
They probably detect it based on IMEIs. But yeah, it's just a speculation without clear facts.
Hey all, sorry for the noob question, I have always unlocked Motorola phones in the past, because at my work, ATT doesnt get signal (My provider), but when I unlocked my Motorola phones, then I would get great signal from T-Mobile, and Cell One.
Well now I got this HTC Inspire, rooted it with the Ace Hack Kit (S-off, and all that), got CM7 on it.
BUT at work, I scan for signal, and all it shows is AT&T (Which doesn't get barely any signal at work). So why doesn't it find T-Mobile or another provider which has signal there?
Also I noticed my dad's iPhone does the same thing, even though his is factory unlocked, it won't use any towers besides AT&T. That really sucks IMO, because I always unlocked them, to get my full potential siginal..
Anyways if anyone could answer this, I'd greatly appreciate it. I could stick in another sim to make sure it's unlocked, but I'd have to buy one on ebay, and then I read all over that the Ace kit unlocks it, so I'm like wtf..

Enter the correct apns for t mobile or flash a ROM that has T-Mobile carrier options.
As for the iPhone I couldn't tell ya

If you used Ace Hack Kit, then your phone is probably unlocked. Whose is your carrier?
For the iPhone, when you say factory unlocked, do you mean AT&T unlocked it. I don't know that any iPhones come unlocked from the factory. When AT&T unlocks a phone (or gives you an unlock code) I think it will only use a non-AT&T signal if AT&T isn't available, i.e. in another country.

Thanks all, and yes his iPhone is factory direct unlocked.. Bought straight from Apple.
Anyways, thanks. I will manually enter the T-Mobile APN and see what that does..
OK, so I am not an expert here but I know enough to give information that should help answer my question.
I have a Verizon (CDMA) Samsung Galaxy S3 (SCH-I535). I'd like to use this phone with a NET10 BYOD SIM card, but I'm not sure it will work. By all indications, my phone is a world phone that includes a GSM band. I say that because I can scan and attempt to connect to both AT&T and a local cell company that are both GSM services. In other words, I can select GSM/UMTS as a network option and it appears to work.
Trouble is, I don't have access to a GSM SIM, so there isn't any way for me to test this without spending money on the SIM card. SO in a round about way, I want to know if this will work. Can I buy a NET10 BYOD SIM, select GSM/UMTS under "Mobile Networks" in teh settings, and expect phone, text, and data to work?
I'm especially hoping to hear from people with the SCH-I535 Verizon GS3 if you've ever done this.
If this is not possible, is there any other BYOD SIM program that will allow for phone, text, and data in a CDMA Verizon phone? If so, what is it?
Thanks everyone.
If Verizon has not unlocked the phone off their carrier, then it will not work. (If you have the Jelly Bean Update, then its unlocked) If it is unlocked, then your in luck.
Mind you that I dont have this phone. But your phone is capable of ATT networks. Just avoid T-Mobile networks unless you want to be on EDGE.

I have a Verizon Samsung Galaxy s3, I have moved it to a straight talk plan, as most of u know there service runs off AT&T and T-moble, Verizon hates AT&T and blocks data use on there network everything but E, What i am trying to find out is can I root my phone and flash a AT&T rom over my Verizon branded phone so it will unlock my 4G? I already have the AT&T sim card in the phone.

I don't think it's going to work. When you signed contract with VZ, they locked your phone to their network. After the contract expired, they will unlock your phone so you can use it on any carrier. If you're not under contract, you can check with Verizon to make sure your network is unlocked, from here on you can use your ATT sim card to register with ATT. Second method, you can search for how to unlock Verizon network and try it. (input a special dial code to access the network unlock hidden menu and unlock from here).Good luck and post back.

The hardware does not support LTE for AT&T. I'd you want LTE on AT&T, buy A GSM phone (or AT&T S3) and live your life. Flashing another carrier rom is not advised by any means on the Verizon S3. Best you'll get with our S3 is edge or 3G. Verizon doesn't hate AT&T, they're incompatible networks because AT&T uses GSM bands and Verizon uses CDMA bands. A small number of phones work across multiple carriers as far as LTE but that's because they have every band included in the phone (for example the iPhone 5S). Other phones on Verizon will only get edge or 3G.

Thats all I really wanted to know i guess, is if the hardware was the same in all samsung galaxy sIII, I am still a noob with smart phones, I thought the hardware was all the same just the firmware was branded to whatever comp. sells them, and with the GSM\CDMA the galaxy sIII runs both.

OK, now I understand what you are looking for. It's not recommend to flash rom from one carrier to another, you could hurt your device. I thought you 're looking to move from VZ to ATT, but seems like you already done that (network unlocked), and now you just want to change the boot animation (Verizon logo during boot up). You should search for VERIZON modified rooted stock rom or custom rom with bootanimation kernel support. Once you installed custom rom/kernel you should able to pick and chose from many bootanimation liking to your taste..and change greeting, display etc...
