Phones that work with CDMA and GSM - Networking

Here's the deal. I'm spending the next 12 months in Canada. I want to buy a phone on the marketplace here and use it this year on a month to month deal with Canadian service. They are mostly GSM on the same bands as AT&T. When I return to the US next year I want to be able to use the same phone on sprint. How do I identify phones that work?

They will say "World Phone" or under the specs you will see GSM bands and CDMA bands. were on most CDMA phone you see "CDMA EVDO Rev A xx/xx/xxx/xxx/" only.

EDIT: You were faster typing eck0728
They are called world phones.
As far as I know Verizon and Sprint have HTC devices that has both, CDMA and a SIM card slot for GSM.
Check your preferred models.

What bands do AT&T/Canadian carriers phones use for full 3g?
Thanks gentleman.

HD2 on Verizon?

I'm just curious if there's anyone out there with an HD2 on Verizon? If not, is it possible to do it? The HD2 is a quad band device, so doesn't it have the hardware capable to be on a CDMA network? I was thinking that if I bought an unlocked HD2, I would be able to put it on my account with Verizon. I guess I would have to be running a different radio in order to do that though.
Anyone have any thoughts, comments, suggestions? I really want one of these phones, but I can't switch from Verizon because no other provider gives me 3g in my area. Plus, my Touch Pro 2 is getting dated compared to that 1gz Snapdragon!
HD2 is a GSM phone. Pretty sure it can't be made to work on a CDMA network.
Technology
GSM: 850/900/1800/1900 MHz
WCDMA/HSPA: 1700 MHz (AWS) / 2100 MHz
Taken from the HD2 tech specs on HTC's website.
If it has a CDMA radio, why couldn't it work if it were unlocked?
Does Verizon have a sim card to put in the phone? If not, how can they make it work on their network.
Verizon does have sim cards, they use them in the Blackberry Storm, which is both GSM/CDMA ...
But It may be like the storm if it is activated via the IMEI that it may not require a sim card ...
rly? i never thought verizon would use sim cards...can we bring non verizon phones them from lets say ATT to their network?
Verizon has SIM cards for their GSM/CDMA world phones. Sprint also has world edition blackberries with a SIM card. The SIM card is there so the phone is able to roam onto a GSM network outside of the USA. As far as I know this SIM card will not allow it to roam onto a USA GSM network, since there are no roaming agreements in place between VZ and ATT/TMO
The WCDMA on the HD2 is not the same as CDMA that VZ/Sprint use.
WCDMA is the 3G standard that GSM providers use. CDMA is well as far as i know the same old CDMA network that VZ/Sprint have used for ages with whatever "bolt on" enables 3G on their network. I dont follow the CDMA standard so i dont know all the specifics about the tech.
Edit:
I just did a small amount of wikipedia research. What Verizon/Sprint use is CDMA2000/EV-DO
http://en.wikipedia.org/wiki/CDMA2000
http://en.wikipedia.org/wiki/Evolution-Data_Optimized
This is not compatible with WCDMA,
Even though they both use "CDMA" family of technology http://en.wikipedia.org/wiki/Code_division_multiple_access
WCDMA is a wideband version http://en.wikipedia.org/wiki/WCDMA
Thanks for the replies guys. This is a bummer though. I was really hoping to be able to get an HD2 to use with Verizon. Oh well, guess I'll wait for the Droid X to release, even though I'd like to stick with WiMo.

Samsung Epic 4G

Hi Guys, dose anyone have any idea if the samsung Epic 4G for sprint supports GSM networks??
as I know it's 4G phone for sprint, works on Wimax networks, and I heard that it's GSM capable as well, is that true?
Thx
I hope that's true... but I think It hasn't a sim slot
Isn't sprint a cdma Telco? Otherwise you'll be hearing ppl like me buying the epic and using it I'm aus. I would love a gsm sgs with kb
Sent from my Apple Newton 2100
I'm pretty sure it's not. Sprint are CDMA (and their "4G" is WiMax). Their phones do not normally have any GSM capabilities.
Epic 4G General Forum
No, it does not have GSM. It's CDMA only and specifically (at least currently) U.S. only.

Actually, the Epic 4G is CDMA/WCDMA capable. WCDMA being a hybrid of different GSM technologies. If you go into the Phone Info Test Mode (*#4636*1111#) > Phone Information, you can see how to change how the phone's radio interacts with different cell towers in the area. While in the US, there's no point in having WCDMA on because there are no WCDMA service providers here. However, when you go overseas... well, you get the picture.
The only reason this phone really isn't strictly GSM capable is because the radio isn't compatible, and there's no room for a SIM card to contain GSM network subscriber data.
"W-CDMA (Wideband Code Division Multiple Access), UMTS-FDD, UTRA-FDD, or IMT-2000 CDMA Direct Spread is an air interface standard found in 3G mobile telecommunications networks. It is the basis of Japan's NTT DoCoMo's FOMA service and the most-commonly used member of the UMTS family and sometimes used as a synonym for UMTS.[1] It utilizes the DS-CDMA channel access method and the FDD duplexing method to achieve higher speeds and support more users compared to most time division multiple access (TDMA) schemes used today.
While not an evolutionary upgrade on the airside, it uses the same core network as the 2G GSM networks deployed worldwide, allowing dual-mode operation along with GSM/EDGE; a feat it shares with other members of the UMTS family."

Droid 2 Global on GSM

Hey guys, I saw this Global edition is coming out, anyone know if it would work straight up on a GSM network? I'm on Rogers in Canada, same netwrok as AT&T and unfortunately GSM android phone selection blows and I've wanted a Droid for ever. Does the Global have a SIM card slot, would it work as a GSM phone or is it strictly designed to work on CDMA and work on GSM from time to time?
Please for the love of god someone tell me it will work as a normal GSM phone, I want a good android phone
Well here in america I know they have the black berrys such as the storm 1 that are gsm and also have verizon "sim cards" in them (yeah, weird I know..) so I want to assume that the phone will be coming with a sim card slot somewhere but honestly I haven't heard much either about the droid 2 we..when I first saw it I had no idea what a "we" droid 2 was lol...neither did google ...hahah

Hahaha thanks man, I'm going to wait till thing gets pushed out finally hopefully someone will tear it apart.
But if anyone else knows anything else please chime in. This could be sweet if it works
Like the global phones of yesteryear (Blackberry devices, a few Windows mobile ones and some feature phones), they come with a VodaFone SIM for use with global roaming. It is SIM-locked (subsidy locked) however and you'll need to unlock it. Verizon routinely does this for regular customers on contract but if you buy the Pro or D2 Global unsubsidized they generally won't and you'll have to unlock it via a third party.
Once it's unlocked: It's tri-band UMTS. I'm not an expert on UMTS frequencies around the globe. I know it'll work in a couple hundred countries outside North America but I have no idea if it'll work at 3G speeds on US or Canadian GSM networks. It'll definitely work for phone calls and 2G data on AT&T, T-Mobile, Rogers, etc since it's quad-band GSM - this is how the global BlackBerry devices work. My old Storm 1 is still in use by someone on AT&T and I intend to sell my current unlocked Storm 2 when I finally break down and pick up one of the new global Droids.
Just got a Droid 2 Global. It has a VZW/Vodafone sim in it, no idea if it's SIM Locked(I'm sure it is). Once you get it unlocked, it shouldent be hard to get working with a rogers sim.
http://www.verizonwireless.com/droid-2-global-motorola-nbsp.shtml
states:
# All–Digital, 800/1900, CDMA EVDO rev A
# Quad Band GSM – 850/900/1800/1900MHz
# Tri–Band UMTS/HSPA – 850 /1900/2100MHz
So according to this, if its unlocked, it should work for Rogers or AT&T 3G
Any ideas on how to get it unlocked ?
i'm sure a third party company can unlock it like how the storm 1s were unlocked, just have to wait and see since it was barely released from vzw.
I got my D2 Global SIM unlocked yesterday. Called VZW Global Support (1-800-711-8300) and they gave me the code (once you put in a non-VZW SIM, it will automatically ask you for the code.) As long as your line has been active for at least 6 months with no late payments, they will hook you up.
HOWEVER, it appears there may be more to the unlocking process. When I did a GSM network scan, no networks showed up. Others on various forums have been reporting the same issue in the last day or so. Normally when you put in a SIM into an unlocked GSM phone, you will see the roaming network options.
It's possible that they have blocked US GSM networks and foreign networks will work fine, but I'm hoping others can shed some light on the issue.

Not quite. If you look at the D2G user guide on the Motorola website, it says on page 12: "DROID2 Global by Motorola switches effortlessly between CDMA, GSM 900, GSM 1800, and UMTS 2100 networks, so you can make calls in over 200 countries worldwide."
So it seems that VZW has restricted use of the 850/1900 MHz GSM/UMTS bands, even though the device has the hardware to support them. Most foreign networks use 900/1800 GSM and 2100 UMTS but AT&T/T-Mobile use 850/1900, which is why no one has had any success with them yet.
Hopefully someone can figure out a workaround.
Yes - hopefully someone can find a workaround for this. The same is true for the Droid Pro in that even once the phone is unlocked it will not work on ATT networks.

In North America and on GSM? The T889 is the one to grab

Looking at the Specs for the 4 versions and if you live in North America and use GSM the T889 seems to be your best choice. You get all North American HSPA bands and DC-HSPA 42Mbps not just HSPA 21Mbps as well as North American 700/1700 LTE.
Looking at the AT&T variant i317 seems we are getting the shaft. You get quad band HSPA only and 2 extra LTE bands you'd never use unless you travel a lot off the continent. My how quickly AT&T put the failed merger behind them.
There are 4 versions of Note:
1. International (+LTE): SGH-7100 / SGH -7105
2. SGH-i317 : ATT+(Rogers+Bell + Telus): HSPA 850/900/1900/2100, LTE: 700/850/1700/1900
3. SCH-i605 : CDMA + LTE 700
4. SGH-T889 : T-Mobile+Mobilicity+Wind : HSPA: 850/900/1700/1900/2100, LTE: 700, 1700
So why does T-Mobile's get DC-HSPA and not the other 2 GSM variants?
So do you know how to unlock the sim slot on this. i use simple mobile and straight talk but I want the t-mobile version because it has hspa+42 and the others dont which I find to be rather stupid. But Simple said I need to unlock it even though it is a t-mo hone and they use their network. Will T-mo unlock it for me if I call them since I am buying it out right.

Can't help you there friend, I'm in Canada. I know T-Mobile used to be pretty good about unlocking devices bought outright but not sure if policies changed. A T-Mobile member should be able to answer that question though.
I've been out of the phone game for awhile, so i'm a little confused. I'm currently on ATT, and as a matter of course, I would pick up there's, but if it doesn't have LTE in the states (I have ATT LTE in my area), then that's just one more reason to switch to T-mobile.
I'm already considering switching due to the cheaper plan and the ability to pick up the phone on a payment plan, which is VERY attractive to me and my current financial situation.
So,, Explain this to me like i'm five.. what exactly is the problem with the ATT Note 2?
nothing if you have AT&T. The t-mobile one only has an advantage if you use it as an unlocked device on pre-paid carriers like straight talk or simple mobile or solavei. The main difference is that if you use a t-mobile prepaid carrier like simple mobile and get the international note 2 it will be edge/hspa+21 onlyin refarmed, if you get ATT it is edge only unless you live in a 1900 re farmed market then it will only do hsap+21, if you get the t-mobile variant it is hspa+42 and has not active lte for when and if prepaid carriers get access to t-mobile lte when it comes online next year. The other thing is the t-mobile variant is a penta band phone which means it will run at full hspa+ data speed on any carrier. ATT or t-mo.

Ah, so since I have ATT in a LTE area (Phoenix), i'll get LTE (42?) on my phone, and no issues unless I decide I want to switch to a pre-paid carrier? But if I did get the T-mobile version of the phone, I could switch it around and I have more options as far as speed goes. Sound approximately correct?
What if I bought the phone from T-mo and switched it to AT&T? Is that even possible and would it have any pros or cons? (Buying full-price phone from T-mobile on their payment plan, using it on AT&T until my contract was up in Feb, then switching the phone to T-mobile with the cheaper plan?

It has LTE, but the HSPA bands are limited to 21mbps vs the 42 mbps HSPA of the T-Mobile variant (which works with AT&T's network on both LTE and HSPA).
Essentially, a faster HSPA radio, nothing else changes
Does anyone know if there will be modem problems like the Att i717 had when switching to tmobile? We waited a long time for a decent working modem which was a hacked blaze modem that worked the best with limited upload speeds, but great download speeds.
Or will the tmobile variant work like the galaxy nexus pentaband on Att or tmobile OOB? I'm tempted to get the tmobile, but will wait for the price to drop.
Torn due to accessories that now are not compatible with the new noteII.

So, If I buy the T-Mobile Note II non-contract price; it will work on AT&T's LTE and HSPA network?

I am on AT&T. I bought the TMOB Note II and unlocked it on cellunlocker.net. very easy.
I don't get LTE even though the device specs show LTE.
I tried different APNs but it always goes back to the default one on my micro sim.

As I stated above:
http://www.androidauthority.com/t-mobile-galaxy-note-2-lte-125982/
The Galaxy Note II features a Qualcomm 9215M chipset which provides the hardware capability to support both HSPA+42 and LTE. T-Mobile plans to reach more than 200 million Americans with LTE by the end of 2013. The Galaxy Note II will not automatically access T-Mobile’s LTE network. We will share more information on how and when the Galaxy Note II will support T-Mobile’s upcoming LTE network when the network is available.

I don't know if anyone cares, but I purchased the international version of the Galaxy Note II. I currently am using it on AT&T network and I maintain hspa+ the entire time. I work in Dallas, Texas but live 45 miles away, and I have awesome coverage all the time. The reason I post this is because all of you wanting LTE, should know more facts about it. LTE is nice, but it's a battery hog. Granted 4G speeds are nice, but in practicality, HSPA+ is obviously not as fast, but it's pretty danged fast and my battery life is pretty darned good as well.
If you are going to shell out the money for the phone itself, buy the International version. You can get them for around $660 dollars, and the price is dropping every day. Don't spend the same amount on a Carrier branded, bloatware infested phone. Just buy the unbranded one and you will be quite happy, I guarantee it.

all you have to do is wait like maybe a week or four days, for their system to recognize that you are using the note 2 on their system. then you call them and tell them that you will be going out of the country and they will ask you for your IMEI number and your email. and you will get your unlock code the next day, hope this help you.

You can try this:
1) With phone on, take off back cover and press your SIM card so it releases from the spring. It won't come all the way out as it's blocked by the battery. This seems fine - I didn't bother trying to force it out as I didn't want to break anything...
2) Once you see the message that the SIM card is removed, go to the dialer and dial *#2263#
3) You should see a menu with band selections. The current setting is "Automatic". If you switch to "GSM All", you will be EDGE (2G). If you switch to "WCDMA All", you will be on HSPA+ (3G, though AT&T and others call it 4G) and you will have lte too
4) Press the SIM card back into place until it clicks. For whatever reason the phone will not recognize it until you reboot. Upon reboot you should see your new setting in effect.
Let me know if this works!
So let's clear all of this up. Will the T-Mobile edition work on T-Mobile AND at&t (hspa+) StraightTalk here in the States? Just seemed a bit confusing and that is what I know is my big question. All help is appreciated.

It's my understanding that the T-Mo Note 2 runs on T-Mo's HSPA+42 network while the international runs on ATT's HSPA+21 network but only on T-Mo's 2G network. T-Mo is currently refarming areas of the country so that the international Note 2 will pick up T-Mo's HSPA+ network. I assume they mean T-Mo's HSPA+42 network.
EDIT: This was from a chat session with a T-Mo rep:
Me: So once the 1900Mhz refarming is complete, does that mean I'd have access to your HSPA+42 speeds?
Mary G: Yes, once the process has been complete, you will have the best service about the calls and most especially the data.
Now, we all know how misinformed reps can be but from what I've been reading, this seems to be legit. So my plan is to get the international Note 2. I get HSPA+21 now, an option for T-Mo HSPA+42 later as I know for a fact my area is currently being refarmed, more developer support, and no bloatware.
If I'm wrong about any of this, please someone let me know.

Will you get TMo HSPA+21 or only on AT&T?

What does "Global Ready" mean for the Verizon Note 3?

I am a little confused about some information I found on Verizon's Note 3 Page. It says that the Note 3 will be a CDMA phone but then lists the following bands:
CDMA Data – 1x and EVDO Rev0/RevA
LTE: B13 (700MHz)
Global Ready (GSM/EDGE: 850/900/1800/1900; HSPA/UMTS: 850/900/1900/2100 MHz)
(original link: http://www.verizonwireless.com/b2c/...t&action=viewPhoneDetail&selectedPhoneId=7194)
Does it mean that if sim-unlocked, it can be used internationally, and how, if it doesn't take a sim card? If it can be used internationally, I would much rather buy a Verizon (for the US) instead of AT&T. I use AT&T only because it's a GSM carrier.
I don't have the answer but I can recommend you to contact Samsung wireless. They certainly have much more credibility.
Good luck

All Verizon 4G LTE devices take SIM cards. They have to, since LTE is based on GSM. Also, historically, Verizon doesn't carrier-lock the LTE/HSPA/GSM part of their 4G LTE phones, so SIM cards from other carriers will work in a Verizon LTE phone out of the box.

I found the answer here, by the Answerer #2. The 4G/Data part of a global ready phone is GSM compatible, and only that part can be locked for data internationally; the calling part will still depend on CDMA in other countries. If that information is accurate, I will stick to an AT&T Note 3.

Truth be told. LTE has more in command with CDMA in terms of radio/air interfaces. It covered within 3GPP standards (GSM then EDGE, the UMTS, HSDPA, etc). Rather than 3GPP2 for CDMA1x and EVDO. That's why Alcatel Lucent had a leg up on LTE since its deployment is more akin (specterally) to CDMA. But they dropped the ball, and except for the US and Some Asian markets, the rest of the world has 3GPP based networks deployed.
the Simple version, is LTE is not directly compatible with any 2G/3G technology, but since its covered in 3GPP, the standards evolved quicker to ensure GSM/EDGE/HSDPA interworking.
And beyond that.. what most people dont know, that interworking doesnt really work that widespread yet. In the US most mobile handsets operate on dual frequencies (especially all VzW models, ATT models are catching up) so they effectively talk CDMA1x and LTE at the same time. iPhones do not support that capability, but GSM has work arounds to allow talk+data.
i'll go back to me hole now
(btw.. anyone with iOS7 and ATT.. what out you've got problems you dont know about when going back forth from 3G to 4G.. I know since at work we talked about how to fix it..
I believe a rumor was that it has the same LTE baseband chip as the iphone 5s so that you could potentially use the Verizon version on AT&T and T-mobile...any truth to that?

I found the answer here, by the Answerer #2. The 4G/Data part of a global ready phone is GSM compatible, and only that part can be locked for data internationally; the calling part will still depend on CDMA in other countries. If that information is accurate, I will stick to an AT&T Note 3.

Not true, I put a T-Mobile SIM in my Verizon Note 2 and made calls, sent texts, and used data on GPRS, EDGE, and HSPA+.

I have also done it with an ATT sim on my Verizon note 2.

Nice! Was this native to the stock Rom or is a custom one needed that has this ability "unlocked"?

Global-ready is basically verizon's way of saying that it has a GSM 3G radio as well as a CDMA radio. That allows the phone to operate in Europe where there is no CDMA service. You can purchase international service from Verizon, or purchase a SIM from a European carrier while overseas. All verizon 4G phones have a GSM 4G radio anyway, because LTE is GSM.
(This means that with an LTE carrier in Europe, any 4G Verizon phone can get data in Europe even if they can't place voice calls (VoIP still possible)).
If I am not wrong with what I am saying, Verizon LTE phones only support LTE BAND: 13, which means that IF you are willing to use 4G with different carrier, they have to support LTE band 13. I have tried to use my Verizon Galaxy Note 2 in South Korea, I was only able to use 3G network via WCDMA, I wasn't able to get LTE service at all. Correct me if I am wrong.

the different N3 variants due in fact support different LTE bands, so you are correct. Minor point not worth nitpicking from earlier post, GSM is not LTE. they both evolved from the same 3GPP standards body, but portions spread spectrum nature of LTE is more similar to CDMA than GSM.
I went to Korea last October, and they wouldn't allow prepaid 4g LTE. They would only allow 3G for prepaid service.
I had a note 2 rooted and custom rom when I went. I'm a US citizen and you have to wait about 2-3 days before you are allowed to sign up for any plan on what they told me.
