Using on At&t?

I'd like to buy this and use on AT&T.
What hoops do I have to jump through to make this happen?
The frequencies are supported (don't care about LTE).
For example if I buy unsubsidized on Amazon, do I have to call Verizon up and get a code from them that will let me use it on AT&T and other GSM carriers?

It's locked for US GSM bands, as far as I know. P3Droid has said that they're working on getting it unlocked. I'm sure we'll hear about it when it happens.

I bought my RAZR M at Amazon (Verizon, without contract) and i use it in Germany with O2 Provider.
No Problem, nothing needed. It´s not locked.

Correctamundo (sp). In further searching it looks like they block the MNC for at&t and t-mobile inside the radio firmware NV settings. Also there is a pesky "unknown sim" or something that pops up every bootup.

Working in India/Asia ?
Hi,
I'm planning to buy one in my visit to US next week. I intend to use it with GSM India.
Has anyone used the phone with GSM provider in India or other asian countries? I was told that GSM capabilities works only in european countries , so wanted to make sure of it before I buy it.
Thanks

Just check and make sure the bands that your network uses are supported. It supports all the standard GSM bands, so I don't see why it wouldn't work.

Do you have LTE menu option on your One? (not EE customers)

I am on Three UK, and although LTE is not rolled out yet, I was surprised that the LTE menu options do not appear at all. For example, why wouldn't I have this option in case I roamed to a foreign country that provides LTE to roamers.
In the network options I only have
WCDMA only
GSM/WCDMA auto
I know those on EE have another option for LTE.
Supposedly LTE and 3G SIMs are the same. In fact Three will provide free LTE access later this year automatically and without any administrative changes.
Could others confirm, if they are not on an LTE network, whether they see the LTE option on the phones network settings?

I think the phone only shows the option to turn LTE on or off if it detects LTE on your network so it should appear automatically once Three launch LTE

I agree! I decompiled Settings.apk of the HTC One and the network selection option uses RadioInfo class to determine what should be shown on the menu. In fact I can even see CDMA & EV-DO there.

Excellent. Perfect answers. Thank you. For some reason I had it stuck in my head that it was based on the SIM provisioning. I should have realised that it is based on the capabilities of the network you are currently connected to rather than a provisioning option.

I have LTE option on mine, got it on vodafone contract from p4u though the phone is sim free/unlocked.

Well done for finding that as it is buried in the P4U thread! Hopefully this thread will help others who wonder why they do, or do not, see LTE options in their menu!

Does this mean that it will work with AT&T LTE here in the US?

No. LTE bands in the US are way different compared to the LTE bands all around the world. I'm not sure about LTE Cat 3 though.

Can't select anything. Menu is gray...sounds logical to me without a SimCard

In reviews I keep seeing HSPA and LTE versions, which led me to believe there are models without the chip needed for 4G.
There is no answer on this though so I'm not going to rush to buy one until I know.

Do you have any other sim(Must not have LTE on it's network) you could try inserting?

GSM / WCDMA / LTE auto
SIM-free from p4u using Vodafone Italy SIM, in an area not LTE covered

Oh crap Now that looks like a sign that it should have LTE option nomatter what sim you insert.
By the way could you tell me what's your baseband version?

Baseband version:
4A.13.3231.27_10.31.1131.05L

Pin Unlocked Code From Brazil

Last month I bougth one Galaxy S5 in San Francisco's BestBuy, I ask for the Unlocked version for Brazil and Ask for the seller this mobile work in Brazil ? The seller say: Yes.
When I arive in my country I tested my sim card and this SIM card doens't work.
I call for the Samsung in Brazil and the USA Samsung.
I Call for my carrier in Brazil(VIVO)
After I found my guide and discovered that it was a North Africa and Middle East Version.
The model is SM-G900H.
I don't know about the my mobile carrier.
I don't know what to do.
Thank you.

fffft said:
Best Buy in San Francisco sold you a 900H phone? That is rather strange as there are no US carriers that use the 900H. I can only presume that they resold a used trade in phone that originated in some other country. You should look under the battery and confirm that you really have a 900H model. AFAIK, Brazil carriers use the 900M variant. Which means that if you really have a 900H it will probably have gaps in it's coverage with your carrier in Brazil.
Confirm that you really have a 900H model.
Ask your Carrier (Vivo) what frequency bands they use in their network
Go to the Samsung website and look up the specs for the 900H phone and see what bands the model supports.
If the phone is missing any Vivo bands, then you will be subject to more congestion and dropped calls than you would with the correct model. And if you are in a smaller town where less frequencies are in use, you may find no coverage at all.
As to the "pin lock", you didn't really describe what you mean.. but it's probably a SIM (carrier) or region lock, rather than lock screen pin. If so then you need to purchase an unlock code from a third party vendor on Ebay or other online site to unlock it for use with Vivo.

This model is right, I checked in my phone. SM-900H. But the VIVO Can't help me. I don't know what I do can I buy one pin code on cellunlocker or another website ?

..

fffft said:
You should first ask Vivo what frequency bands their system uses. If the 900H phone won't work well on the Vivo system, everything else is moot.
As to unlocking, you would have to get a SIM unlock code AKA IMEI unlock code (PIN) from Ebay or another online unlocking site. Not Vivo. Also consider if you want to make a claim against Best Buy or not? Do you want to try returning the phone because they sold you the wrong model or not?
Good luck.

You should confirm that information with Vivo. Then go to the Samsung web page and see if the 900H supports all of those Vivo frequencies or not.

Did you actually talk to Vivo to confirm their information?
A full model number would clarify the latter i.e. what region your phone originates from may determine which bands are accessible.

Today I recive this e-mail
Gabriel,
It seems you may still not be receiving our responses.
Often, the unlocked phones require a 5 minute phone call be made with a North American SIM card before they're fully functional throughout the world.
Is there someone in San Francisco you can send the phone to? They could then bring it in to us and we could attempt to unlock it for you. If we cannot, I will refund the item.
Thanks,
Dustin

Is Indian Edge+ (SM-G928G) compatible with major Canadian carriers?

I would be moving to Vancouver in 2-3 months, so wanted to know if I can pop-in a GSM sim (of one of the good carriers over there) in the the unlocked version of Edge+ available in India (SM-G928G). Which all bands it supports, any idea?
Thanks

I wouldn't be so sure. Check the band it supports for 4G. Usually Indian and Canadian carriers use different bands, so a 4G device capable in India might not work with 4G of Canadian carrier. Other than that, phone should work without a problem. If the 4G spectrum is not supported, your data would be limited to 3G.
Check what all bands are supported in your model, you can see it here I guess. Also, check here for the LTE spectrum used by different carriers in different countries.
Hope that helps!

Try pressing *#*#4636#*#*
Once you're at the Test Menu, select Device Information-> Set preferred Network Type -> LTE/GSM auto (PRL). This is how I change my network type on AT&T. If your network/device is compatible with LTE, you should see LTE symbol below 4G symbol on notification bar.

In my AT&T model, it works. And I believe it should work just fine for any other model as well as long as its S6 Edge+. Not really sure why it's not working for you. You just need to press #*#*4636*#*# quickly in the native dialer and that should open up the menu. You do not even need to click on dial button to make a call. You can search for your carrier specific model's service menu codes in google.

I downloaded an app from the play store and it shows that I am on T-Mobile B4 band. I will try that again to see.

Unlocked V35 and Band 71 (600 Mhz)

Does the Unlocked V35 include band 71 for t-mobile? I have done a search and the results are not conclusive. I know--or think--it is enabled for T-mobile wifi calling. But I do not know much else.

Yes, it does have band 71 (600Mhz).
In the dialer put in (277634#*#). It should show the band 71.

Thanks very much. I am trying to decide between the V35 (unlocked) and V40. This info helps.

The phone is compatible, however the carrier may not allow it.
T mobile for example only allows band 71, wifi calling and volte on their phones.
In other words: in addition to the right hardware support you need to have the right modem software and rom

I am using unlocked V35 on T-Mobile and it has Band 71, Wi-Fi Calling and VoLTE. Works well for me.

Has anyone know of a way to see what bands are enabled and or a way to disable some bands?
I use a signal booster when in bfe. And some times phone wants to switch to bands booster don't suport. Like 30 and 66 .

The later builds of the v350 awm firmware seem to work with tmobile WiFi calling and early ones, no. The certain fix is to flash your awm with ulm firmware and wifi calling works.
