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

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.

T Mobile is the exclusive US carrier for Sony Xperia. That includes all the different phones with Xperia in the name including the Ultra. If T Mobile does not sell it, it will be in the Sony store. The phone will work on ATT as well although the version currently on sale outside the USA will only work on the 3G network.

The c6806 is already available, and is the LTE version for north America.
Take a look here http://negrielectronics.com/sony-xperia-z-ultra-c6806-unlocked-black.html from what I read on internet while looking which I need in Europe. People was saying that the LTE bands on this model are those for North America. ATT use 700 and 1700 bands and T-Mobile use 1700 only. Both of those bands are on the C6806 version.

It looks like that website still says "Preorder" instead of order.. looks like its still not out yet.
Hey guys
If I remember correctly, if the phones is compatible with ATT it usually runs well on Canada LTE's right?
Thanks for any input regarding Canada better model to chose ( Rogers for example )

[Q] Sprint G3 LTE freq

Hi
was thinking of signing up for this great phone. Thing holding me back is whether if I travel overseas say to Asia/EU, would I be able to pop in a 4G/LTE sim card (assume unlocked by Sprint) and use the local data plan? The common band in the country I visit would be band 3,7. Would this work?
I think the 3G should work but not sure about 4G.
Thanks for any enlighten information.
Cheers.

The sprint G3 has bands 25, 26, and 41. I doubt it has any other bands.
All American variants are capable of running on all American networks, if they are SIM unlocked. The only American band not covered that I am aware of is band 5 on ATT.
They should work on 4G almost anywhere in the world really. I just checked again and yeah, other then band 5 all American variants of the G3 have all other bands in the radio and are capable of running anywhere you have a sim for it. Cheerio.

Using Gear S alone internationally with ATT version

I have a ATT version which i have unlocked and been using with Tmobile for about 5 days without issues.
I then wanted to use it internationally since i have Verizon for phone. I wanted to take advantage of the free texting and internet when abroad. my wife has Tmobile as well on her phone.
So we have been to Munich, Athens, and Barcelona and i have not been able to get any service whatsoever. meanwhile my wife with her Note edge has no problems with service.
Does it have to do with the bands of this att version?
has anyone used their ATT version Gear S internationally?
North American bands only. it's a dual-band phone. All Gear S versions are dual-band only. So, North America version will only work in North America (850 and 1900Mhz). Rest of the world uses different bands (900 and 1800Mhz).
What foxbat said. Sadly, Samsung didn't deem it necessary to make this quadband
Maybe the next version...
I don't think it is about the need but about the technical difficulties to squeeze in enough RF components and antenna for all four bands in such a small watch body. Remember, even in US, T-Mobile version should support at least 3 bands to get full 3G coverage but the T-Mo version of the Gear S only has two bands
ha....
May be the next version.
I don't about size limitation. i see cheap quad band watch phones from Asia that are slightly "smaller" than the Gear S.
I think of taking the sim out and putting it in an unlocked phone next time I am out of country to take advantage of tmobile great international perks.
i know usually Tmobile will be able to detect that i put it in a normal phone, but i am wondering if they will be able to do so while international roaming. Any thoughts?

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.

Carrier Unlocking the U.S. S9/S9+

My question remains, when carrier unlocking an s9 or s9+, is there any way to make it available on different network types like say if the phone started out using a carrier that uses CDMA, is their any way to flash it to utilize t-mobile's frequency bands?
I unlocked two galaxy s9+'s that were on xfinity, which uses verizon towers. The two phones did unlock, but only for carriers utilizing CDMA. I was hoping they would be able to be used on t-mobile after unlocking, but they can't. Only messaging and data works using a t-mobile SIM card. Verizon works fine. SO my question still remains, is there a way to make it work?
I used itekimei .com to have the phones unlocked, as I found they were suggested here on XDA. And they weren't really able to answer my question either. They said it should work with t-mobile, but the conversation ended with "t-mobile is having problems with unlocked phones." This is super frustrating trying to get an answer.
Edit: I found this forum https://forum.xda-developers.com/galaxy-s9-plus/help/sim-unlocking-sprint-samsung-galaxy-s9-t3783571 which debates whether it will work or not. Also this one specifically about Xfinity https://forum.xda-developers.com/galaxy-s9-plus/help/xfinity-mobile-unlock-service-t3796349. But mine didn't work. I don't think U.S. S9's are cross compatible from CDMA to GSM. I have been searching and searching and can't find a way.
Yes, the US unit hardware is cross compatible. Heck, Verizon itself isn't all CDMA. They are phasing out CDMA soon and most of their network is LTE.
I have a US unlocked S9+ and can use any carrier in the US. You could too, all you need to do is flash the US Unlocked firmware to the device using Odin.
Your problem may be the Xfinity firmware restricting certain bands is all. Or possibly the device isn't really unlocked.
