Gear S is a dual-band device. So, it depends on what version (mostly importantly which region) of the Gear S you have and where/which carrier you are using it on. For example, North American versions of Gear S can't be used elsewhere and vice versa.

it was att network carrier i m trying to use it with Vodafone Egypt carrier my model is SM-R750A
software version is : R750AUCU1ANJ7
I contact with some online Co. they give me Nck, Provider, Subprovider and Defreeze codes
when i insert Vodafone sim card into my gear s it asked for network unlocking code .. i did enter the Nck code they give me and its accepted
but still no signal
so i think if there is a way to use the others codes like the provider or defreeze codes it may work
what do u think??

It is physically only capable of receiving 850MHz and 1900MHz signals that are used in North American countries. Rest of the world use 900MHz and 1800Mhz frequencies. Like I said, North American versions of Gear S can't be used out side North American. No codes will make it work. Different hardware.

[Q] Nexus 9 LTE on Vodafone UK doesn't get LTE

Hi,
There's a thread going on on the Vodafone UK forums about the Nexus 9 LTE not connecting to Vodafone UK on anything higher than 3G. I don't think this is very well known as the LTE version isn't as popular as the Wifi version, and then there are multiple mobile operators to choose from, so this might not affect many people.
Basically, a known working Vodafone 4G SIM in a known 4G coverage area will only establish 3G, never H, H+ or LTE/4G - this has been tested with multiple devices (I've got two here now) and multiple SIM's. The devices are unlocked, Vodafone don't require IMEI registration or anything like that. It should just be a case of putting the SIM's in. I've done all the checks I can think of (SIM's in another device - they get 4G, other operators SIM's in the device get 4G) etc.
Vodafone use LTE band 20 (and band 7 in a very few locations for LTE-A). Band 20 is known to work on the radios in the device because the same devices can connect to EE, who also use LTE band 20.
HTC are not interested as they say its a network problem, the device can register on EE and advised me to contact Vodafone.
Vodafone are saying its an unsupported device, I didn't buy it from them and don't really care, their first line support said the SIM is registering on their GSM network but never registers on the 4G network hence no coverage. After a conversation with second line support I was told that the device is trying to register on band 8 (900MHz) rather than band 20 (800MHz) which means that its a software/hardware problem - I'm a little bit dubious about this as how would they know unless it was negotiated by the SIM or something as their equipment uses 800MHz... ? I think he was basically lying to me to fob me off.
Google don't even have a way of contacting them about the device.
So as a consumer I'm stuck! Is there anyway I can debug the device myself? Can I see what bands are being used at different points in he SIM registering process with any software? Basically - any help or advice at all guys. It sucks to spend a load of cash on a device that half works, but what REALLY sucks is having no way to escalate a clear cut problem because there are so many companies involved!
Thanks in advance!

unexpected Response from network

I have just purchased a Gear s, which looks like it was purchased from the USA (T-mobile) & I am using it in the UK. It has been unlocked but when I put in the sim I do not get any single & within the call settings it displays unexpected response from network.
Any Ideas what could be wrong?
Thanks
Gear S is a dual-band phone only. So North America models won't work in rest of the world and vice versa. You are SOL.

Can you suggest where I might find out if my Australasian purchased Gear S + S4 will work in the UK?
Both devices bought outright (though so was my iPhone but the carrier still locked it into their service as soon as I put their sim card in)
To ask the question another way - if say travelling back to the uk (and assuming my devices are compatible with their networks ) - would I be better off prepurchasing a still quite expensive international package from the Australian bandits - or would an international package from Amaysim Lebara etc work with one their sims in the gear s and another in the galaxy device?
my provider is now offering slightly less extortionate international deals but as you say it depends on whether the GS is compatible with the other country's network.
I'd be happy to do that tap tap tap thing and just use the Gear S as a phone back in the uk
thanks
You need check Samsung for the specific frequency bands any of these specific local variants support. For Australia, it has networks use 850Mhz (which is one of the bands North America uses), 900 and 1800 (both are commonly used in rest of the world). So, I'm not sure what bands an Australian version supports.
Gear S for North America supports only 850MHz and 1900 MHz.
Gear S for rest of the world supports only 900Mhz and 1800 MHz.
Australia and Brazil have more complex frequency usage. So I don't have any idea. Japan is WCDMA 2100 only. So Japanese version contains no cell radio.
Thanks
I will get it exchanged
Best model for Western Australian users hoping to use it abroad
Gear S for North America supports only 850MHz and 1900 MHz.
Gear S for rest of the world supports only 900Mhz and 1800 MHz.

The somewhat-difficult-to-navigate Samsung Aus store is currently showing 2 different models
Telstra (900/2100) ----- GSM 900 DCS 1800 ---- 3G UMTS B1 (2100) B8 (900)
Optus Vodafone Virgin (850/2100) ----GSM 850 DCS 1800 ---- 3G UMTS B1 (2100) B5 (850)
Th Gear S still doesn't appear on the Telstra website ....(though it's their PAYG simcard in my watch)
but Optus is already offering the watch with a shared data plan
I bought mine from a 3rd party electronics reseller "**** Smith" but the Gear S has since disappeared from their store - go figure!
Thanks again for the ongoing education on battery considerations, pairing solutions, different types of network frequencies, and all your other helpful contributions
I'm not posting the details above in the hope of more free specific advice but more to share my experiences with other less techie users and potential users - plus writing it down helps my own understanding

Gear S AT&T Unlocked but does not recognize my carrier

I unlocked my gear s via cellularunlocker.net but my carrier does not recognized by my gear s. Anyone have a solution to this. My idea is that network band does not support. Im using GSM carrier so is there any way that it can be changed? Please help me out. I actually paid $25 to get it unlocked so i dont wont it to go to waste. Thanks alot.
Have you checked if your model supports the bands of the carrier you're trying to use? For e.g. a sim from Canada GSM carrier may not work with an unlocked UK watch.

hmm seem like it is the problem.. Is there anyway that i can change band in Gear S
No, it is the hardware limitation. You will have to buy another that is designed to work with your region. Basically there are two types of Gear S: one designed for North America, one designed for rest of the world. Neither will work in other region due to dual-band limitation.
Even within North America, there are also CDMA version for CDMA carriers and GSM version for GSM carriers.

Gear s T-Mobile not Working on a GSM SIM Card outside USA

Dears,
I need your help. I have Gear S R750T running on R750TUVU1ANJ7. I have just rooted my Gear S following the exact instruction in this link: http://forum.xda-developers.com/gear-s/development/definitive-guide-to-rooting-gear-s-t2973455
Unfortunately, SIM Card still not working even after rooting. There is no coverage appear in the watch.
Do you have any solution or suggestion to overcome this problem.
Thanks,
A.AZIZ
I have the exact same issue.
USA phones (and GearS watches with phone functionality) use a different communication channel than those for Europe/Asia.
So, if you're trying to use a phone/watch designed for one set of frequencies (for example USA uses dual band 850/1900) on a network with a different set of frequencies (in Europe it's 900/1800) it will simply not work.
You should definitely research this kind of info BEFORE buying any GSM type device (phone, smartwatch, 3g/4g tablet, ...) or you'll end up with a "WIFI only" device
EDIT :
Here's a list of countries that use the same frequencies as USA :
https://en.wikipedia.org/wiki/List_of_United_States_wireless_communications_service_providers
Also, for Yemen the network uses the GSM 900 system, so an American phone won't work : http://www.gsmarena.com/network-bands.php3?sCountry=YEMEN
Thanks verzipo for your reply
Thanks verzipo for your reply
I don't think the problem is the band frequencies as most mobiles whatever be GSM or CDMA brought from USA are working properly here in Yemen. Only mobiles which are factory locked or restricted by a carrier need a back door solution either by rooting or some utility applications. I feel frustrated and cheated by buyer that I spent more money for the Gear S on un-used feature in my country.
Anyway, I will try my best to use the WIFI feature to its end limit to compensate
Thanks Man again.....

What if i choosed the wrong ROM country?

I am having a problem with 3G network for along time even though we have 3G coverage in my place
i installed lolipop 5.0.1 and it worked perfectly but the 3g problem still
im in north africa but my phone manufactured in brazil ,under the battery it's written ANATEL and a number of 10 digits following it Do you think this phone works only in brazil and only under Alcatel. network ?
now an idea comes into my mind is to install a brazil region ROM with a brazilian carrier , but some told me ROMs are all the same and it won't resolve your problem
Do you think this phone works only in brazil and only under Alcatel. network ?
Dear experts please advice me in my case .....Thank you in advance
Each phone is set to use different bands. So unless the band's match up you will have issues.
but i do not have that carrier in my country here
It's not the carrier. It's the band's that are programmed into the device itself. This is something you have to be very careful about when getting devices from other carriers and countries as they don't all use the same bands.
I would look your phone up and see what bands it supports and then check what bands tour carrier uses. It's most likely they don't use the same ones so you will never see 3g.
so how do i check the programmed band on my phone?
By checking the device under the carrier that it was made for.
