[Q] Which US carriers? CDMA version? - Galaxy S II Q&A, Help & Troubleshooting

So I would love this phone but I am with Sprint and it doesn't seem like there is a CDMA version of this phone to be found anywhere. Am I lost or is it assumed there will be one compatible with Sprint and Verizon. I have no problem switching, I just hate AT&T's crappy network and never was a huge fan of T-Mobile. What can CDMA carreirs expect? I hope not the Tegra 2 version (gross). Otherwise I will just hold out for the evo 3d.

[Q] query regarding cdma network and rooting on evo 3D

In our area , there is available EVO3D cdma for cheap rate, it has a T-mobile logo on it, but the buyer says tht he has unlocked it for reliance cdma network
question is if i root it and put a custom rom on it, will it still be unlocked at reliance or it will be locked ??
if it has t-mo branding on it, it's probably gonna be the sensation, which is not the evo 3d. Secondly, t-mo is gsm only. If I were you, I'd verify if it really is the 3d, not the sensation, but I'm sure it will be the latter (if it isn't some scam to begin with)

I'm fairly certain my CDMA EVO 3D will NOT ever operate on a GSM network w/o changing the radio hardware inside.
Unless the GSM version comes with both radios inside, it will be impossible for it to operate on a CDMA network. "Unlocked" is generally a GSM term as GSM devices can be unlocked and then operate on any carrier.
Where as CDMA devices have to be programmed for a specific carrier. The programming process for a CDMA device can be a bit complex for people w/o computer experience.
Hope that helps clarify! I'm sure somebody else with more knowledge on the EUR versions of the GSM EVO 3Ds can chime in from their experience.

Also very great point! Don't think there is any GSM EVO 3D version being officially sold in the US under the TMO or ATT brand (the two largest GSM companies in the US). Perhaps a foreign GSM version of the EVO 3D, once "unlocked", could operate on a US GSM carrier such as TMO or ATT, but fairly confident TMO and ATT havent ever sold a GSM EVO 3D.
As a double check, if you wanted, a quick glance at the line up of phones available on their web site should help clarify. Or if you really wanted, call their customer service departments and ask about a EVO 3D or any type of 3D device to see what they have to offer.

[Q] Amaze 4G on Sprint network...

My girlfriend wants to include me on her new Sprint account. Sprint doesn't have an equal to my Amaze. Is this possible? Will everything be functional (except T-Mo's add-ons, of course)? Please shed some light. Thanks!
How do you plan to connect a GSM phone to Sprint's CDMA network?
no not possible, 2 different technologies. Sprint uses cdma and tmobile uses gsm.

The Amaze is GSM meaning it REQUIRES a sim card as do all T-Mobile and AT&T phones in the US. Sprint is on a CDMA network which works with the antenna inside the device, an internal "sim"card if you will. There is NO WAY to use a GSM device on a CDMA network. There are ways to flash Verizon, Metro, Alltel and other CDMA device to Sprint's network but not any GSM phones. Take a look into flashing the HTC rezound from Verizon to Sprint's network. That device has essentially the same specs but is CDMA. Hope this helps.
Why not ad her to yours? it will be way cheaper than Sprint.
Id be glad to do it for ya

[Q] Sprint not available

I was wondering if there is a way to use another carrier to get 4G for my tablet? I want 4G for my tablet but Sprint is not in my area. I would have to use US Celluar or Verizon. I checked Verizon and it would be $35ish a month. How do I change set it up for another carrier? Hoping I don't have to go as far as rooting it. Thanks!

Unfortunately you can't, even with rooting. That's because 4G isn't a wireless protocol, but rather a standard that defines minimum speeds for protocols that wish to call themselves 4G (or something like that). Different carriers achieve 4G through different communications protocols. Verizon and AT&T use LTE. T-Mobile uses HSPA+. Sprint uses WiMAX. Currently Sprint is the only carrier to use WiMAX, and the only other WiMAX provider is Clearwire. But since Sprint uses Clearwire for its WiMAX, if you had Clearwire available in your are you'd have Sprint 4G, too. (Also, Sprint is abandoning WiMAX in favor of LTE in the coming years, so WiMAX is pretty much dead).
Your best bet is to find a carrier that offers 4G service in your area and buy a wireless hotspot and a plan from them. The advantage is that you can also use that plan for other devices such as laptops and WiFi capable phones.
Thanks for the reply.. That sounds like a good idea!!

[Q] World phone capability

If the qualdcom processor on the EVO is ment to support LTE which in turn uses a sim card shouldn't that make the phone a world phone I know it is suppose to have an embeded sim. But my true question is will we be able to reporgram the sim once we get root or will write have to go with more of a hardware mod if we wish to make it a world phone.

Sprint uses embedded LTE technology to my knowledge, so its not like on Verizon where there is an LTE sim card. Also, this phone is a CDMA phone, and therefore does not have a regular sim card slot (Like phones on ATT or TMo). No software modifications will change this, and I highly doubt that anyone could even attempt to make a hardware modification to make this phone a world phone. Also, and LTE sim card is not the same as a regular sim card, as they perform different actions (access to LTE and the rest of the network is seperate).
Yeah I was thinking that it does not have the slot the thing is that the processor does support gsm also I was kinda hopeing it was like the rezound it is cdma phone on Verizon. It was found out that just by removing verizons LTE sim card and adding a gsm one it allowed the phone to work as a gsm phone.
the evo lte does not have the GSM and HSPA+ radios to be a world phone
When I preordered, the rep told me it was a world phone. I didn't think she was right but I didn't say anything.
Yeah i read the same post on Engadget i think. What a bummer was hopping it was since it is rocking the same processor that the at&t one (correct me if im wrong). Plus like i also stated was hopping it was like the HTC rezound on Verizon that with a experiment it ended up working. O well .... still kinda wanna take it apart and try wouldn't be xda without some experimenting or moding.
My friend has a Droid bionic which wasn't supposed to have GSM support, but it did through some hacks on rootzwiki and using a T-Mobile sim card. I think that the s4 includes a GSM radio, so its probably possible at least if the sim card can be accessed. Lte is GSM based so it is likely that GSM support is there if software is modified like it was on the bionic.

Sure, you can use it anywhere in the world that has a compatible CDMA network.
Many identify world phone with GSM radios (which the Evo 4G LTE does not have), but CDMA (which it does have) does work well for roaming in Asia.
I've roamed with my Evo 4G across Japan, Korea, and China for both voice and data. There's a full list of countries with CDMA roaming on the Sprint website. As soon as you arrive in country (if roaming works), you receive a free text with the rates and instructions on how to make international calls.

[Q] Do all HTC One's have the same radio frequencies?

I've been looking around for some good deals on a off contract HTC One. I'm currently on AT&T but I've noticed T-Mobile and Sprint HTC One's seem to be selling cheaper. I've read that all HTC One's have the same hardware including radios, but what about the LTE bands? Is there any difference between the carriers? And would I first have to unlock another carriers branded phone in order to get it to work on AT&T?

I'm pretty sure the T-Mobile One will work with AT&T's LTE network. Not sure if you need to unlock the AT&T or T-Mobile Ones to use on each other's networks. You can't use Sprint on anything but Sprint's network. Sprint uses CDMA and AT&T and T-Mobile are GSM networks.
You should get a T-Mobile version of the One, that is the best version to get. It will support both AT&T and T-Mobile LTE bands, plus regular AWS 4G on T-Mobile. You will need to have it SIM unlocked to use it with AT&T, eBay is where you can do it.
From where I am, socal, on CL everywhere, the AT&T version is always cheaper. T-Mobile version is harder to find and usually costs more.

Thanks for the answers. Good to know a T-Mobile phone will work should I purchase one.

Curious as well, can someone give solid proof of all bands? I wouldn't want to just fall back on word of mouth when purchasing a phone based on this info.
Thanks!
