Does AT&T V10 on Verizon? - AT&T LG V10

My girlfriend really wants the mint colored V10 at&t has exclusivity over, but she's on Verizon. I'm not sure how locked down Verizon is. I believe V10s have both CDMA and GSM radios. Please and thank you

It may accept the Verizon SIM but it may not connect to LTE.
Carrier branded devices are tricky. We're not completely to the point of switching devices between carriers in the USA as fluidly as it should be.

No AT&T has no CDMA radio, it will not work calls/sms on Verizon.
EDIT: I know it would only be the back portion of the phone, but you could get the light blue / cyan / mint? back battery cover off ebay or amazon.

So what about global travel to countries that don't have GSM networks? Is the AT&T variant useless?

Verizon CDMA doesn't work outside of US and has to switch to GSM globally (Verizon Global/world phones are CDMA domestically and GSM Globally), so if AT&T GSM is useless in Countries without GSM (are there any?) then the Verizon is as useless. . Anyways as far as I know, there are only GSM and Verizon variants
Verizon works on AT&T, since it switches to GSM. AT&T does not work on Verizon, since it's CDMA.

There are plenty of countries that aren't GSM. Canada, Argentina, Puerto Rico, U.S. Virgin Islands, China, India, Japan, Austria, Germany, Poland, Russia and Sweden to name a few.

[Q] Droid 2 Global 3G Bands outside the US

Hi all. I've just found out about this brilliant phone. Had no idea it existed. I've always liked the Motorola Milestone (qwerty physical keyboards are a must to me) however i ended up getting the wrong version of the milestone (european) with the wrong 3G bands for my carrier so i could only get Edge speeds.
Anyways, it seems like the Droid 2 Global version uses simcards. I live in the Dominican Republic, Claro (my carrier) runs on the 850/1900 bands and it seems like the D2G can work with them, in theory. I've been reading a couple of threads regarding this though, it seems like those bands have been locked out by verizon so people don't use it on other US carriers such as AT&T which happens to run on the same bands i need (850/1900). But others say its the carrier ID that has been locked out. I read something about a user being able to get 3G speeds on Chile, but i've no idea what bands he was using.
What i want to know is, if i ordered a Droid 2 Global phone, would i be getting 3G speeds using my Claro simcard here after having it sim-unlocked?
There's also the Milestone 2 of course, but they seem to cost $500+ plus they dont specify which bands the phone works with. I dont want to end up buying the wrong phone version again. Also, It seemsl ike the droid 2 global is being sold for a less ($300-400).

read the spec
I am using my SIM-unlocked D2G fine here, on a carrier that uses 850MHz UMTS.
The Milestone 2, as far as I know, is still only available in a 900/2100 UMTS variant so far.
From what I gather, the lock Verizon put on the radio to prevent use on US GSM carriers is based on the MCC (mobile country code) number associated with networks based in the USA, and not the frequencies themselves. In effect, once unlocked the phone will work with any GSM provider (on a supported frequency), except those based in the U.S. This would explain why the AT&T 850MHz network (MCC 301) doesn't work, whereas the Telstra 850MHz network I use (MCC 505) does.
One complication about buying a Droid 2 Global now, is that from various reports on this forum, some devices don't respond to their SIM unlock codes (!) and are effectively unlockable. If I were buying a D2G now for use on a GSM carrier, I'd only buy one that has already been unlocked - wouldn't want to take the chance on getting a phone that is unlockable. This might be why some are being listed for dirt cheap!

Wow thats not good is it. Thanks for the advice, i'll make sure the phone is unlocked. I've never really understood how phones are unlocked by third party anyways. But I understand you can have them unlocked by giving verizon a call and under certain conditions, they'll provide the unlock code for free.
I was in the Dominican Republic last week with my D2G and it worked perfectly (unlocked using Rogers Canada service). Claro service sucked a bit (coverage wise) but worked fine (3G), Orange (EDGE) seemed a bit better where I was.
I am pretty sure you will be fine AS LONG AS you get unlockable/unlocked D2G.
ok one last question,
does anyone know if a droid with bad esn will work ok with a different carrier's simcard if unlocked?
I would assume droids with bad esn will be going for cheaper on ebay
bas esn mean d phone could be stolen so it will b a hassle to clear the esn
How can one know if the phone has a bad ESN? Just wondering.

Obtain the esn from whomever you are purchasing from. Then ask Verizon regarding the esn you were provided.
Sent from my DROID2 GLOBAL using Tapatalk
but wouldnt you only need a clear ESN if you're going to use the phone with CDMA? or would that affect GSM usage as well ? (simcards)
According to the eBay listing I bought mine from, it has a bad ESN (at least, it explicitly stated "will not activate on Verizon") - but the GSM/UMTS radio works fine.

Bad ESN will only affect use on Verizon and its MNVOs (possibly). GSM networks will work fine. Just remember though if it's not already unlocked, and the ebay unlocker codes don't work, it will probably be near impossible getting verizon to give you the code for a phone with bad esn.
thanks for the info. I''ll look for unlocked plus bad ESN phones on ebay and see if theyre any cheaper

What carriers can use?

I am currently using the phone as a pure wiiFi item. I will be coming out of contract with them and do not plain to get a nother contract. I know that att has a pay as you go for $.10/min with a $15 for 100mb. Belive it or noth that is enough for me for data as I normly only us the phone for about 20 min and 10-15 mb a mounth.
What I was woundering is if I unlock the phone are there other carriers I can go to with this phone so that I can compair? Thank for any help on this.
Yes, when you unlock you can choose any carrier of your choice
Big Dog Infuse I997 ICS CatyRom
Which country are you in? You basically need to check what bands the carrier you want to switch from uses. They need to match what your infuse can use otherwise it won't work.
The phone supports: UMTS 850/1900/2100 and GSM 850/900/1800/1900. I think T-mobile runs on a different band but I don't know for sure as I live in Canada. Here in Canada you can use this phone on Rogers (the carrier that sells it), Bell, Virgin, Fido but I don't think it will work on WIND. If memory serves me correctly it might not work on T-mo, Verizon or Sprint (because Sprint and Verizon are on CDMA). If you are in the US you might want advice from someone other than me though.

yeah but umts bands are incompatible so you still only get 2g.
Isn't it possible to band unlock the infuse, but it requires more than the typical efforts. wasn't some group offering to do it for $50 if you send your phone to them?
Straight Talk. Uses AT&T's networks. But you have to buy a phone off of them with a sim.
Sent from my SGH-I997
There are different types of carriers in America and there are many things scarier can,do to lock certain devices to the network. Tmobile and att are gsm carriers and have some compatibility But they use different bands. The talk works and edge works. No 3g.
Sprint and Verizon are cdma and are not compatible. However Verizon,has phones that are both gsm and cdma and can,work on att. Nextel has Sim cards but are iden. Boost is also half cdma and half iden. And begin is basically sprint.
Then there are the no contract deals like strait talk. Problem is the Sim may be locked to the phone and even if you know the phone has a Sim and is working off atts network it may not work. The strait talk thing is only known to work if you buy a $200 Nokia smartphone and many of those have Tmobile Sims that are locked to the phone. I'm not sure how to tell the tmo version from the att version without looking at the Sim itself. Strait talk seems to just buy rights to use other networks, I've seen phones at Walmart with gsm on the box and others with cdma on the box. I think they use all the major networks depending on the phone.
I also saw an ad for simple mobile. Seems promising but appears to be Tmobile
So no 3g.
In Canada almost all carriers are 100% compatible with att phones. All but one but I forgot the name. So if you're Canadian you have options.
Do not know if you know about this- New T-Mobile Monthly4G $30 Unlimited Web & Text with 100 min of talk

[Q] Unlocked One S from Canada (bands)

Hey guys just wondering if anybody has unlocked a One S (bought from a Canadian Carrier) and tested it out on Wind or Mobilicity.
I emailed HTC asking them about the bands supported by the phones and this is the reply I got.
Fido: HSPA 42 Mbps
Bell: HSPA 42 Mbps 2100/1900/AWS GSM 850/900/1800/1900
Sasktel: HSPA 42 Mbps
Telus: HSPA 42 Mbps
Virgin: HSPA 42 Mbps
Click to expand...
Click to collapse
Asked them if the other phones had the same bands
I do apologise for the misunderstanding, but the bands would be the same for the One S on each network.
That being said, I will suggest to contact Wind Mobile to verify if a unlocked phone will work to its fullest potential or not. The reason I mention this, is that some providers put a limit on the connection, on an unlocked phone.

So I was just wondering if anybody has tested this out and knows if it works on Wind or Mobilicity by just unlocking it or if the AWS bands are "locked" just like the Galaxy Note.
Wrong. Canadian One S are not AWS.
If we would have AWS onboard we would have the T-Mobile US phone

Are you sure Penta Band ONE S exist in Canada/USA ? read post #3
As for the official HTC site says. HSPA/WCDMA:Europe/Asia: 850/900/2100 MHz
BUT Your links would make sense according to the note Network bands in regions other than Europe and Asia Pacific may be different, depending on the mobile operator and your location.
I too, am trying to find out too what bands does the Canadian version support
Fido , Bell, Virgin all listed HSPA 850 1900 2100 but Telus only listed 850 1900 , so that leads me to believe 1700 is not supported.
However at the same time, the international version isn't penta band, nor the T mobile version... Where are theretailers getting their penta band One S in black?
Maybe the device is penta band from the fatory but carriered modified ?
My Telus One S arrives next week and I will unlock it but ufortunately Wind doesn't
operate in SK so I won't be able to test it.
I tried to look at the demo phone and I couldnt find the menu option to select networks.

The black unlocked international One S is for sure not pentaband as far as I know and supports less bands than the blue version. I am assuming the blue versions are all the same and just branded differently. My suspicion is Fido/Bell/Virgin/Telus aren't listing the 1700 band so that people do not buy and unlock them to use with Wind/Mobilicity.
That's too bad there has to be someone out there that has attempted to try it on Wind/Mobilicity. It's such a pain how every site/company is showing different specs.
The European version will not work with AWS. Currently the only *confirmed" AWS version is the T-Mobile US version. However if S-Off is ever achieved then flashing a T-Mobile US radio could "unlock" the bands in the European version and other versions a la the Snapdragon Galaxy Note.

I am aware the the European one does not have AWS. However I am not asking about the black European model. In Canada we have the blue model just like the one with T-Mobile in the States which leads me to believe that the Canadian version=the American version; I just need some confirmation.

Does anybody mind looking under the cover for the model / FCC ID / Industry Canada certification numbers and reporting back with the carrier they got the phone from and the FCC ID. They should be printed on the label near the headphones / headset jack.
These are the variants available in Canada.
PJ40100: UMTS Band V (850)
PJ40110: UMTS Band II (1900)/IV (AWS)/V (850)
PJ40200: UMTS Band V (850)
PJ40210: UMTS Band II (1900)/V (850)
I went to Telus and Bell today ( the Fido and Sasktel stores didn't have working demo models ), I checked the FCC tags and both of them showed "PJ40110". on the top line.
I didn't look at the FCC ID or IC.

Awesome! Thanks a lot, I really appreciate it. Now I can safely go out and buy this with no worries
Please be aware that you will buy an unsupported phone, unlock the bootloader to root the phone, most probably voiding your warranty in the process (there's talk that the root-only (and not requiring unlocked bootloader) method for the NA One X works on the One S) then Sim-unlock the phone (by a paid code or the new hack), find the APNs for your carrier...
... And hope that all works...
I don't want to scare you but make sure you fully understand all risks. Specially if you buy the phone outright and don't have an account on that carrier...
Despite the fact that I can't test data (as it should be locked in my account) here is a shot telling that I'm on 3G UTMS (which can't be done with this SIM on a non-AWS phone like my iPhone).
I got one from Virginmobile had it unlocked it and am now using it on Mobilicity.
The Rep at the store assured me it wont work but i tried it and it did.
Reason for buying from there was because it was on sale.

[question] cdma / gsm ?

Hey guys, i would like to buy an one s the next days but i have an important question, since the c2 [s3 processor] will be the only one sold in the future in some european/asian countries (not in mine, just s4 here):
whats with CDMA / GSM? i read that t-mobile us has gsm phones but does that mean that the one s is only sold in the gsm version?
i am just asking because i don't want a phone without "enough" custom roms in the future, because there will be some for the c2 version only and if there are a lot for cdma only it won't be much for a european s4 gsm version.
thanks!

CDMA and GSM are different ways of transmitting radio (cell phone) waves.
In the U.S., to my knowledge, only Verizon uses CDMA. All other carries use GSM and most international carriers also use GSM. If you buy the phone from T-Mobile US, you can only buy the GSM version. If you buy it from Verizon, you can only get the CDMA version (this assumes Verizon actually sold the One S). I'm not sure about international carriers, but I would expect that most operate the same way. It would not be smart for a carrier to build out both CDMA and GSM networks due to the expense involved.
No matter where you get it or which SoC it has, S3 or S4, it will be GSM.
Thanks for your answers but it is too late, no one s from tmobile left in Vienna, they say one month... but I'm sure then they will get only c2...

Verizon and Sprint are CDMA. T-Mobile and AT&T are GSM. By extension, Virgin and Boost are CDMA since they piggy back of off Sprint here. We also have regional carriers like MetroPCS and Cricket kthat are CDMA. IIRC, T-Mobile US phones are better than AT&T phones with international compatibility.

Sim unlock galaxy s3 on verizon? :(

Can someone please help me with me new galaxy 3s? I just bought it from USA and i want to use it on Greece but it is locked on verizon.... What should i do?
That's an 800MHz/1900MHz CDMA phone. If Greece is like the rest of Europe and uses GSM, the phone doesn't have the radios to work there, so you can't use it. (The SIM is for data, not voice, but you need the basic connection to the network for it to work, and a CDMA phone won't connect to a GSM network.)
You should sell the phone to someone in the US (who wants a Verizon phone - it can't be "unlocked" for other carriers) and buy the GSM version of the phone.

That's an 800MHz/1900MHz CDMA phone. If Greece is like the rest of Europe and uses GSM, the phone doesn't have the radios to work there, so you can't use it. (The SIM is for data, not voice, but you need the basic connection to the network for it to work, and a CDMA phone won't connect to a GSM network.)

New Verizon phones have worldwide roaming ability (including the S3) so it should work on any GSM carrier outside the US.

It is a sch i535rwb 4g phone. How can i check if it has a worldwide roaming phone? Also what should i do so that i can use it in Greece?
You need the SGH T999 (The GSM variant of the SGSIII) The Verizon variant should NOT work in Greece on a Greek carrier.

Are you sure for that? If i am not wrong this is an US version too, whats the diference and i can use sgh t999 in Greece?
I used to think it was native but apparently not. You can still enable worldwide roaming though.
Here's the thread, you need to do some hackery

You can just root it and and flash the synergy mod rom and it will work on any carrier
Does it actually have a SIM card slot or just a built in one?
If you're looking to use it primarily in your area I'd look for a different phone - sell or trade this one. I've heard the GSM can be used but that it's pretty terrible and certainly not what you'd want for a primary phone.
