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.

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.

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.

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.

So this may be a dumb question, but I can't help but to wonder. Is there a way to use different carrier's networks? I know each operate on their own frequencies or ranges, but it seems with all the things you can do with this phone it could be possible. I think it would be amazing if I could use T-Mobile's or Verizon's 4g network, or just switch carriers whenever one had better service/reception. Is there an app for this maybe? Would it require installation of different modems every time you switch networks? Would you have to modify sim card somehow? Is there any kind of information I can read on this somewhere? Any info is appreciated.
You can only connect to the carriers network for whom you have a sim card for.

I know that. I'm wondering if there is a way around that. Verizon doesn't have sim cards right? At least not removable like ATT. Maybe it's just a matter of programming/software on your simcard. I'm just wondering if doing this would be possible. I know how the game goes now, just wondering what stops us from doing this? Aside from the morality issues of stealing.

Verizon gives u a SIM card if u say u are traveling abroad, and want to use their service abroad.
AT&T and T-Mobile along with some others are aa GSM style of network. Verizon, sprint and others.are based on a CDMA network. They are completely different. The only it could be possible if is all the companies 4G networks were the same, such as LTE.

Yes their is. If you have AT&T you can add T-Mobile's APNs along with any other carrier that is GSM that supports your frequency. However, if you switch to that other carriers APN you will be bill astronomical roaming charges.

AT&T is switching to UMTS for their 3G. Same 850 and 1900 bands though. And will be upgrading to LTS for 4g sometime in the near future. I actually install the UMTS cabinets, 850&1900 radios, and coax at towers around here. So there's no possible way to take whatever it is on a sim card that works for a CDMA network and throw it on an AT&T simcard somehow(maybe like a stored contact) and use that programming selectively?

The sim card ties a phone to a carrier. There is no software to bypass this. Some phones support 2 sims via 2 slots. As for vzw, there sim is a vodaphone sim and only works in other countries as there is no vodaphone service in the us.
If you want multiple gsm carriers you need multiple sims. EU has a hundred different sim cards to support all the carriers.

The OP is wondering WHY it needs a sim card. Stop being such a smart ass.
No I don't have a problem with using a SIM, I was with TMobile for a while and know how useful it is, as a matter of fact when I was in the Navy we had a sim imbedded into our smart card IDs. I appreciate the link, does this also make it a world phone or will is it only used for LTE?
No, this is not a world phone. The SIM is just a spec that is required for LTE

While the Charge (or, any other LTE phone) isn't technically a "world phone", it can be if the country you go to supports LTE - at least partially.
The Charge doesn't support VoLTE (Voice over LTE), which requires a special modem chipset. I believe the Revolution does have the VoLTE chipset. If you have an LTE phone with VoLTE, your phone will eventually be a "World Phone" when other countries implement VoLTE.
That said, you may be able to use your LTE phone in an LTE country to make calls using a VoIP application, such SIPDroid.
On the bright side if you switch between 4g phones, you can just plug in your sim card like a GSM phone.
That's what I do to switch between my Tbolt and Charge, none of that x228 stuff. Just plug in my sim and all is well

That's IF the country you are in is using the same LTE bands as the US. Think about it, how many GSM bands does a phone need to support to work for Voice and Data in every country?
GSM and CDMA are forks of the same technology.
Way back when things split, the CDMA-based carriers (at the time AirTouch, and Sprint) decided that (partially in order to keep carrier lock-in) it would be better to include everything needed for connection to the network within the body of the phone. Essentially, CDMA phones have the SIM integrated into the SOC.
In comes LTE, which Verizon decided on as their 3.9G technology, but also happens to be SIM-based and doesn't support the integration with the SOC like CDMA.
If you look closely, the primary technology behind GSM networks is actually called WCDMA.
LTE must dictate that the SIM be removable then because it could easily be integrated. Otherwise 4G looks like an afterthought.
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?

I dont think this is true as verizon can still lease their spectrum to other carriers like Straight Talk to piggy back off their network. The biggest problem for him is going to get a non-approved 4g device on verizons network. Verizon does not want people taking flagship devices to other discount carriers. Networks like Cricket dont actually own any spectrum, they just lease it from the bigger carriers at a discount. But verizon only allows a select group of ESN's to connect to it, usually for crappier phones. Some people will go so far as to clone their ESN to get it to work, but that requires special tools developed for your phone and can be quite tricky.

I doubt Sprint is using 700 they are probably using spectrum they got from the nextel acquisition (not looking stupid now lol).

those other Verizon 4g Lte phones, like the moto Bionic, have radios and antenna that support those GSM frequencies, and the engineering software tools to perform those tasks have been leaked.
Afaik, but I haven't looked in a while, after making those seem edits it unlocks Gsm/Edge for Att, T-Mobile and global roaming. I think it also enables hspa for Att but not T-Mobile due to frequencies the bionic's radio supports or doesn't support. It does not enable Lte for any other carrier.
its my understanding that the radio chips and antennas in the TB only support Cdma/Evdo and VZW's upper 700mhz block LTE
It also doesnt help that ril for the thunderbolt is closed source because of the svdo capabilities in it.

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.
