Can I unlock Infuse 4g to Verizon ?

No this a gsm phone.

Nope, this doesn't support CDMA technology, which is what Verizon and Sprint use. Unlocked, it will support GSM (SIM cards) like AT&T and T-mobile as well as foreign GSM providers. There are a couple of phones that do both, but to my knowledge AT&T has never had one.

No. No GSM phone can operate on Verizon's CDMA2000 network. Some of Verizon's phones are dual-mode and can accept a GSM SIM, but it doesn't go the other way around.
The Infuse can operate on T-Mobile's network, but only at EDGE speeds - TMo uses different bands for 3G than AT&T does.

Any luck on getting sensation to work on Verizon?

I'm thinking about switching to Verizon, and I saw that I could buy a sim card from them. My sensation is unlocked and was wondering if I inserted this sim card, would it work? Anybody tried this yet?

It won't work because VZW uses 700mhz while tmobile only supports 850,1900,1700 and 2100
I believe people have had success with using verizon 4g on AT&T and vice versa. Also, I think people are able to use tmo phones on ATT's lte network since AT&T galaxy note owners are able to use it on tmo's 3g.

There's also the whole CDMA-not-GSM and Sensation-not-LTE issues.

[Q] Verizon SCH-i535 on T-Mobile LTE

how can I get an unlocked sch-i535 to work on tmobile and access the LTE network, is there a certain rom, kernel, apn, or any other settings/process that can be done to work? I have a tmobile sim card in it and am only running on Edge Network, and since Phoenix (where I live) has LTE I want it bad

Shouldn't work. Most anyone has gotten (like you) is Edge data once they've edited their APNs. Additionally, each carrier supports different LTE bands so it's not compatible on Verizon's GSIII. It's not like the Optimus G which just had a dormant LTE band waiting to be exploited.

VZW to ditch CDMA.

Do you ever see a day when VZW will ditch CDMA and start using GSM? I hate not being able to use my phone with another carrier. I also don't see any real advantages to CDMA. Any thoughts or opinions on if you see this happening?

Verizon will switch from CDMA to GSM, probably never. CDMA is very well suited for covering long distances with a minimal number of towers. Therefore, CDMA is the best platform for countries with large land masses. CDMA is more secure, and the phones are more energy efficient. Also, CDMA phones produce far less EMI.
If you really need the international roaming, there are Verizon phones with global capabilities. Or switch to T-Mobile or AT&T, and deal with that headache.

I would love to see verizon ditch CDMA for GSM! Its a pain to have accumulated phones that I will not be able to use once I switch to a GSM provider. The problem is that it doesn't seem like there is any incentive for Verizon to WANT to switch from CDMA

CDMA is better than gsm in some ways and gsm is better than CDMA in some ways I prefer cdma

Verizon already has been rolling out LTE, is it not just a matter of time before they start to put all services onto that? I would think that at some point Verizon just won't need CDMA anymore.

There lte is CDMA...

Nope its CDMA at a higher frequency to allow faster speeds. How do you think these little companies do it like cspire? They can do it for cheap on CDMA

wish they would just because i'm not stuck buying a new phone whenI leave them.
Trying to decipher the threard now on if I can make my Droid 3 use ATT in USA

LTE is based on GSM technology. On current Verizon LTE phones, CDMA is used for voice and texting (and data when there's no LTE), but data (when there is LTE) goes over LTE. That's why you guys have SIM cards in your CDMA devices.
What verizon is planning to do is abandon CDMA for completely LTE phones in the future. What this means is voice, texting, and data will go over LTE, similar to VoIP. It's called VoLTE, which means Voice over LTE.

It's actually at a lower frequency than their CDMA bands. 700mhz band. Lower frequency has better wall penetration. Frequency has nothing to do with bandwidth either.

I know for a fact that lte runs on CDMA at cspire it may be different but there isn't no sim on cspire phones and they couldn't afford to upgrade all there towers with gsm anyway so is there different kinds of lte?

GSM doesn't just mean SIM card. LTE uses GSM protocols. Sprint is the same as CSpire; no SIM card slot. However there's a chip that emulates a SIM card inside the phone. It's probably the same case for CSpire users. The HTC One on Sprint has a SIM card slot though. So does the iPhone 5.

Well, if a phone supports LTE, it doesn't necessarily mean it can do GSM. For example, the HTC Rezound and most newer phones on Verizon do GSM, but only because the phone happens to support it because the chipset is designed for global roaming. But the Galaxy Nexus on Verizon, for example, doesn't do GSM even though it can do LTE.
There was a guy who took the Photon Q on Sprint (the Motorola slider), unsoldered the chip that pretends to be a SIM card, and soldered on a SIM card reader. He was able to use normal SIM cards in his Photon Q afterwards.

don't some CMDA phones have sims though?

Those are phones that also had a separate GSM radio in them for traveling abroad (like the DROID 2 or even the Touch Pro 2, which were not LTE phones).

Ahh, ok. nice to know. Going to attempt to get my D3 on USA ATT this weekend. I hope it works as I really don't want to shell out money for a new phone. I like my D3

There going to leave CDMA eventually but not for GSM. There is a new form of LTE they will eventually adopt because its backwards compatable with the original LTE . Than they can pull all of there cdma and older lte equipment along with the 1x stuff that has been phased out and removed as it dies.
I dont see all of this happening for another 4-5years for the full switchover though and its posable they may leave cdma in some markets to help coverage as it seems some areas LTE just eats it.

[Q] How to Switch to Verzion with T-Mobile's myTouch 4G Slide

Hi guys I have a question hopefully someone can help me with. I have the myTouch 4G Slide from T-Mobile but I want to use it on Verizons network. I know how to root and unlock the boot-loader but are there any other steps I need to take before this is functional? Any help would be greatly appreciated.

Version uses sim cards right? If so just search the threads here on how to sim unlock your phone, I believe I read one or two here before. You can also have it unlocked by tmo if your on contract with them or you can buy sim unlock codes

Verizon uses CDMA. The MT4GS is a GSM phone, so there is no way to use it on Verizon's service. It doesn't have a radio that is compatible with Verizon's towers.

Exactly! There is absolutely no way to get this phone, or any GSM phone that I know of, to work on Verizon's system. Even T-Mobile's new LTE service is different than the LTE from Verizon (not that this phone can work on either of those, either).

Haha, couldn't remember myself, hence the foggy reply! CDMA is such a pain, makes me wonder why anyone uses a carrier with it, I mean unless you never travel or want your phone to only ever work with one carrier....

There are a few Verizon and Sprint (both CDMA carriers) that have GSM backup. They market them as their "World Phones". The iPhone5 is one of them. If the phones have the GSM portion unlocked (Verizon automatically unlocks theirs, Sprint will unlock on request after a certain amount of time), you can use a foreign SIM and the GSM radio of those phones. But, you have to be careful, the phones default to the CDMA and if you have roaming turned on, in some countries that could be a VERY expensive oversight with roaming charges.
