using vzw LTE device outside USA ?

LTE cards are basically next gen GSM sim cards, right?
Will a Verizon (cdma) phone that is LTE capable like the droid bionic work outside the USA?
Since LTE needs an LTE sim card, would an LTE device work outside the USA simply by removing the LTE card and inserting a local country sim card?
Thanks!

No the radio frequency is different.

If your device has an antenna that supports GSm then yes it will work. You wont get LTE of course.
Ala my Tbolt works in Europe.

I didnt' think the Tbolt had any GSM capability, where in Europe does it work az?

I have seen conflicting information on whether or not the Bionic has a GSM radio in it. On GSM Arena, they have the specs up now, and emphasize that it doesn't have a GSM radio, but when the phone went through the FCC, there are articles talking about how it will be a 'world phone'.
Does anyone work for Verizon, or actually know the situation? It baffles me that there are no LTE devices that are also usable in Europe.

Verizon piggy backs on Vodaphone's network in Eruope.
Check out http://b2b.vzw.com/international/Global_Phone/Europe/Germany.html for proof.
It isn't cheap though

Thanks for that page. I see that Verizon uses that network overseas, but it doesn't appear as though the Bionic has a GSM chip in it, does it?
There is almost zero CDMA in Europe.

Yeah, you won't get 3g speeds - but you will have basic voice and sms service.
My phone stayed at 1x the whole trip - but the vast aray of free hotspots in Munich kept me well connected.

Bionic is supposed to be a world phone with 3G service on European frequencies:

Thank you for that link. It seems that for every link that I find that says that the Bionic has a GSM chip in it, there is another link that says that it doesn't. Phonearena is a good site, so this keeps me being hopeful, but then I find sites like this: http://www.gsmarena.com/motorola_droid_bionic-3710.php
They don't have a GSM chip listed, and specifically say that, "it will not work on any GSM network worldwide."
I guess that we will not know until after it is released and Verizon is finally allowed to talk about it? I tried talking to Motorola about it, and I have e-mails out to Verizon, but I'm not getting any information back that is relevant.

Check the FCC page for the Bionic here.
It's referred to in the user manual.
Though I will say, I couldn't find the GSM stuff in the tests, so it may not have made the final cut. I guess we'll see for sure on Thursday.
The link you had was for the original Bionic (the Etna). It got canned and reworked. The code name for this version was the Targa. This also has a model number of XT875 vs. the original's XT865.

I am currently living and working overseas. I can confirm that 4G LTE does not work in China. Actually, neither does verizon's 3G, which i believe is evdo (?).

No dice on it being a world phone it looks like it.
Phone Arena posted the user manual from Verizon's site. The manual's been updated from what Moto submitted to the FCC. It looks like GSM/UMTS was dropped from the final version. Makes sense considering it wasn't mentioned in the FCC test reports.
Bummer.

I would like to make a note that this phone can work in specific countries. Yes GSM is used throughout the world as the primary network (freq. band) which this phone does not provide but, it can still work in countries that has the CDMA network capabilities.
If you look in the "Getting Started" guide which came with the phone, there are Three sections about the "Go Global", "International Calling", "International Romaning" service provided by Verizon.
What I find odd is why mention this service if this phone is not a world/global/international phone..
HERE is an Example of some Countries that this phone should work in.
Japan, Taiwan, China, South Korea, Philippines, Thailand, Bahamas, Canada, Mexico, India, etc....
for a full list you can find it on Verizon's Wireless Site.
I also called Verizon to verify if this phone will work in Japan specifically as it is a primary destination of mine. They told me that in their records, The Motorola Droid Bionic phone will work in Japan. There is though, supposedly, an issue in texting where you can receive but not send
Even if its on the list, call them to verify to be safe before making a trip with the phone.
I did also ask about Europe to verify since they use GSM and they said that it would not work there. I was testing to see if they would say something opposite to what was mentioned publicly... something possibly hidden lol
Note: The primary focus was, does this phone will work in a specific country that I might travel to while still using the Verizon's plan.
If you are looking to try and get this phone moved to another service provider in that country on the other hand, I cant guarantee that it would work or is even possible. This was not a question that I brought up to Verizon.
Also I did not ask about the 4G/3G Data plan overseas.

Bionic in Japan and China
I went to China in 2005, my CDMA phone worked fine, however it was an old phone. No smart phones in 2005. I went to Japan last year with my Droid x. Everything worked well, Navigation text, phone calls. However the entire time you are in 1x mode. No 3G service in Japan, for Verizon customers. However ATT customers often had no service. I only had no service in once place. Not in a big city.
Since Japan is moving towards LTE there is no support for 3G on the CDMA network.
I do not think an LTE World phone is ready yet, for the difference band Frequency LTE operates on in different regions of the world. I would be happy if my phone worked in Japan, and it will but you will not get fast speeds and Data is very expensive on the network. When I went it was unlimited data for $64. Now Verizon has international plans. That will give you up to 250 Mb for $100. THe good thing is at 1x, how much data can you use.

not sure why this thread is spanning more than two posts.
it's cdma. no gsm chip.
there are about a dozen countries that support cdma. google it.

well the thing is the 4g chip for LTE uses a GSM network, thus the sim card... but the GSM chip works for 700 mhz OMLY, which is a LTE network frequency ONLY, so if you roam out of country, to do texts and calls, it would have to use CDMA. Not only that, but atm verizon is the only LTE carrier to use 700mhz. (correct me if I am wrong about that) so unless verizon has LTE tours out of country (vodafone?) you only will get 4G here, and if you do get 4G out of country, not only would it cost you a arm and a leg, but if there is no CDMA in the area, you would have data only. no calls, texts, or such.

[Q] Importing a Tab from the U.S

Hi. I am concidering to buy a Galaxy Tab 10.1 from the united states. But i was wondering if it would support the norwegian GSM network ?
Somehow i got the impression that Europe and USA have different types of technologies to connect phones to their carriers..
Becase we have _INSANE_ taxes here in norway, i'm guessing it will be much much cheaper having a friend sending it overseas from the us.
But i need to know if its compatible with norwegian gsm-based network.
Edit: will all tabs be cdma only?

Also: bump
Sent from my GT-P1000 using XDA App

Theres no way they will all be cdma, and what are the networks you use?

Some will be gsm, some not (i think verizon is cdma, tmobile is gsm; gsm needs sim card). Just make sure that the model you buy requires a sim card. Then it will work. Alternatively you could get one from Canada.

It's possible, but consider two things (as above)
1. get a GSM tab (onw with a simcard slot)
2. have it unlocked (sim lock removed)

Unfortunately i dont know anyone that lives in canada. I need a friend that can ship it directly to me, with a note attached to it saying "happy birthday" or something to get away with the taxes from customs.

There are two types of GSM Tablets in the US. One is from AT&T, the other T-Mobile.
Both tablets support 850/900/1800/1900mhz bands so if your carrier is on these bands you should have no problem getting it to work. Whether its 3g capable or not, that's a different story as at least in the US only AT&T has the tri band UMTS necessary to get 3g and voice capability.

Is that better or is there a problem

GSMArena have it listed as supporting 900/2100MHz UMTS 3G. That means Optus/Voafone/Virgin in Australia, all UK networks, and any UMTS provider in Hong Kong except NTT DoCoMo.
In my experience, GSMArena usually f*ck up their frequency listings a lot.
It would be a huge departure for Verizon to make their new world phones 900/2100MHz when ALL the other world phones they've released are 850/1900/2100. Plus it would make the majority of their roaming agreements with partners useless.
I think it's pretty safe to say it will be at least 850/1900, perhaps 850/1900/2100. That means if your network uses 900MHz you're out of luck.
EDIT: Old thread, sorry. Have no idea why this one popped up!

Droid 4 can be working in hk because it is a cdma/gsm device, BUT verizon has locked down the gsm.
so basically, it wont work

DROID 4 is not a GLOBAL phone. It will only work on Verizon network.

ifixit's teardown has a chip identification:
http://www.ifixit.com/Teardown/Motorola-Droid-4-Teardown/7759/2
Has a Qualcomm MDM6600 chip:
from wikipedia:
MDM6600™:
Multi-mode modem
HSPA+ with data rates of up to 14.4 Mbit/s
CDMA2000® 1xEV-DO Rev. A/Rev. B support
GPS functionality, including support for Assisted GPS
I'm out of my element here, but that suggests global capability....as to whether it can actually be used, I haven't a clue.

Found some info here http://www.gobi.com/resources#Documentation
Specifically the Gobi3000 product sheet http://www.gobi.com/sites/default/files/Gobi3000r4.pdf
It seems like the chipset can support everything, but CDMA and GSM support are in two separate firmware images. Also even if the chipset has support, there's no guarantee that the requisite antennas and such are connected. But I've already read a few places that Motorola/Verizon plans to enable global roaming with a firmware update in the future, so I'd guess the hardware support is already in place.
The doc doesn't list support for 1700MHz AWS in the frequency list, but it does say "Prepared for UMTS-AWS" which implies that it could be supported with additional tweaks. So probably no US T-Mobile 3G support out of the box, dunno.

Hi,
i'm from italy, anyone know if motorola & verizon release Droid 4 for Europe ( milestone 4 ) with all gsm band? same the droid 1 and 2 released for EU with name milestone 1 and 2.
i read some rumors about a possible declaration of milestone 4 on Mobile World Congress 2012.

I'm not sure, but the Droid 4 does use a GSM Sim, and that would make me think that you could pic up a Sim in country and put it in your phone. I mean if you don't have to unlock your phone first.

I'm interested in this one too!
My carrier uses 900 and 2100mhz for hsdpa...

Apparently, the Droid 4 will have GSM roaming eventually.
http://www.theverge.com/2012/1/12/2...-and-lg-spectrum-will-have-global-gsm-roaming

There are a lot of possible show stoppers.
First, I don't think that this was an official VZW statement.
And, even if they will make GSM/HSPA work, it's unclear if and how SIM unlocking will work.
Let's see how it will work out with the xyboard tablets ...

The problem is D4 has dedicated LTE radio now which requires SIM card. My guess ia the Verizon's SIM is only compatible with their own network and can't do roaming just yet. Issue could not be technical at all. To be safe they decided to lock down GSM/HSPA radio for now. Once they figure out how their SIM cards can roam properly on other providers, they will likely push OTA update to enable the HSPA settings.
Verizon doesn't care if we want to use another sim card. Will likely make everything possible to prevent us from doing so. They however want their clients to pay for roaming badly. I am sure the matter will be resolved as this is a big revenue point for them.

Yeah, LTE uses GSM... there is no CDMA LTE connection which is why all the 4g phones have GSM frequency capability, but Verizon has them on a tight lock. It is possible for them to allow you to use in certain GSM areas but I don't think they would unlock it to be used with any other service.

The challenge isn't the hardware, but rather that the Droid 4 is a Verizon exclusive currently.
Thomas is correct; the radios have more flexibility than Verizon has allowed it. They have announced that sometime this year they will enable global roaming for the phone via their networks, which to me says firmware push.
I am hopeful that Moto will eventually release a GSM-friendly unlocked version, a la the Milestone vs the original Droid.

Verizon HTC 1 to T-mobile

Hey everyone. So i have a question that i can't find on here so im going to ask it. I have a Verizon HTC one unlocked. The sim car works fine and i can do everything on the phone with the T-mobile sim card. The issue is its always Edge data. Is there a specfic APN i have to use? something im not seeing? Does anyone else have this issue? It is a stock factory HTC One, nothing custom.

I don't think the Verizon model will have the correct radio frequencies to use T-Mo's LTE or HSPA+ network, hence you're stuck on Edge. If you're staying with T-Mo, I'd suggest selling your current One and buying a T-Mo specific HTC One.

This is pulled from Verizons website
Network: LTE, CDMA/1xEVDO Rev. A (800/1900 MHz)
Global Network: EDGE/GSM (850/900/1800/1900), HSPA/UMTS(1900/2100) aGPS capable for E911 emergency location, aGPS (assisted), sGPS (simultaneous), Standalone GPS, eCompass, GLONASS
T-mobile uses the 1900 Mhz base band and the HSPA as well. So i don't see the issue in that one.

From what I can tell, nobody uses the dual 1900/2100 to achieve 4G like TMO. The UMTS referred to on that phone is for worldwide use, not US. So while it may have the frequencies, it is not set up to use them like TMO. Your software and firmware are set up to work with Verizon and overseas, not with a competitor like TMO. TMO refers to theirs as HSPA+. However, it might work on the new "reframed" 1900 bands (which is called HSPA), but those are not very highly deployed. Unfortunately, I don't see LTE on that list of frequencies. The TMO LTE is really great. EDIT: I mean TMO LTE, which is also 1700/2100.
I suppose you could try unlocking it and flashing the TMO radio, but there is an entire thread on trying to unlock TMO frequencies (in that case on the developer version), and no one has figured it out yet.
I concur that your best bet would be to sell the phone and get a TMO model.

What he is referring to is that what Verizon uses as "3G" is CDMA technology. So although they (T-Mobile and Verizon) may be on the same frequency they're using totally different technologies. Just because it has a sim card slot for a Verizon sim doesn't mean the device will be compatible with another carrier's sim. A custom ROM would not resolve this issue. Your best bet would be to sell this device and purchase one from T-Mobile. :fingers-crossed:

My understanding is that the devices run on different systems for 3G and different LTE bands. You wont get more than GSM compatibility (GPRS, EDGE). Hopefully it is something that a software hack can fix but if you read around all the HTC One forums you will see no one has found it. Right now it is not possible.

It is hardware not software that is the issue. The T-Mobile variant has different bands than the other variants including Verizon. T-Mobile is a GSM variant while Verizon is a CDMA variant. Here is a comparison of the specs for the variants.

CDMA and GSM technology requires the antenna to be done differently. If they are not programmed to use those signals. Nothing you can dox will change it short of putting a new antenna in.

Because you can only unlock GSM. Cdma uses the serial/esn number of the device.

Has there been any update on this? I called tmobile and they said it was simply because I couldn't put in the APN. So, there's no chance that rooting the phone and putting a tmobile rom on it would fix the problem and let me get more than edge speeds.

I myself have been wondering the answer to this. The device might seem the same but under the cover they are different. The actual daughter board which the camera, vibrating thing, volume rocker, power button are connected to are fairly different from each other. The CDMA variant is not compatible with the GSM variant. Not even by adding a CDMA daughter board to the GSM motherboard and vice versa, the are made quiet differently and will not be able to use GSM bands on a CDMA m7

[Q] Using Verizon (1060) phone in the UK (on GSM)

I'll be going to the UK for a couple of weeks and want to buy a "pay as you go" sim card when I get to heathrow to get a UK phone number and make local calls.
Can I just buy the nano sim from the provider into my verizon phone and it will work or do I have to "convert" my phone with the t-mobile software before I go to activate GSM? I don't care about LTE, data over cellular is just fine for emails and msgs. My moto x is the unlocked Verizon dev edition.

It should work fine as is. VZW devices are already sim-unlocked.
Keep in mind, that the VZW version does not support the LTE frequencies used in the UK. It also doesn't support the 1800mhz UMTS band that is used by some carriers in Europe....so you MIGHT not even get HSPA+ if your carrier happens to use that band...
There is nothing you can do about either of the above 2 issues, since the radio hardware on the VZW variant doesn't support these bands. Phone calls & texts will not be an issue, since it DOES support all the GSM bands.
Good Luck

According to the specs, my phone has exactly the same bands/frequencies as the AT&T phone, except for lte. I guess I have to see if anyone in the uk uses 1800 utms and avoid them, I guess. But per your post, if I put a gsm sim in the phone it will just start to work on gsm in the uk. That's great news.

I don't know where you saw those "specs" but they are wrong.EDIT: I now see that you said "except for LTE" - this is correct.
Everything I said previously still applies...
The attachment should clear everything up for you.
The VZW unit does support all the same UMTS frequencies as the AT&T unit, but NOT the European model.
And finally: It probably won't "just start to work" on GSM. You WILL need to go to Settings > More > Mobile Networks --- and then select "GSM/UMTS". Then it will "just start to work"

Thanks....especially for that last step. I kind of figured there was something that I had to change on the phone

You may also have to manually input the correct APN info for the carrier you choose, but there should be directions with the Sim. It may just work, but it didn't for me in Australia. I had to manually do it.

^ The above is correct, but ONLY applies to DATA & MMS. Talk/text will work even without an APN. Most times, the appropriate APN is added automatically from the SIM.
