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 :

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.....

I Got last month one SX56 from Siemens, stated by the store to be use it worldwide.
However, it never connected with cell company in Los Angeles, which I
didn't bother with it since I was planning to use with TIM in Brazil, and the chip that I was using is from over there. I have arrived in Brazil two days ago and still no connection.
My question to you is that the band switch program(from XDA, installed by the store) shows that 900/1800Mghz band is possible, however the reference guide booklet only mentions dual band 900/1900;Is the intermediate band 900/1800 a software function commanded by the band switch program or the actual hardware must be triband in order to work the 900/1800?
Please note that under automatic configuration, it gives a choice of choosing TIM Italy telecom, which operates 900/1800.
Any suggestions or advices on your part are welcome.
Thanks,
Alex
Your hardware is not capable of working on 1800 band.
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!
Has anyone been able to access Service Mode on the X Mini (or some other Asus phone)?
I have an unlocked X Mini that I'm trying to make work on a local Wireless provider (GCI), and I've successfully rooted the phone using the primary technique already described on this forum. After putting in my sim card all I get is a small 'x' next to the signal bars. I was able to get the phone to work with an AT&T sim just fine, and I've been able to get another AT&T phone (Galaxy S4) to work after changing frequency band. GCI uses 850 and 1900 for 2G/3G and Band 4 for LTE. AT&T phones also use those bands, so I should be able to configure the frequency bands accordingly. Unfortunately, most of the solutions I've seen on the interwebs are geared toward more common Android phones.

Code:
*#*#4636#*#*
The 4636 option gets me to a potentially useful menu, but what I'm looking for is more like the *#2263# menu that allows for setting frequency preferences. I've successfully used this menu on a Galaxy S4, and now I'm looking for something similar on the X Mini.
No one else has had a problem connecting this phone to a non-AT&T network?
I have mine unlocked also..and it connects fine with T-Mobile on my end...
T-Mobile US here. I just got my AT&T unlock code today and successfully unlocked. There's no non-LTE service where I live, and sure enough, I have no service. I found a thread on using some Qualcomm tools to change the bands used by the modem, so I may try that.
First of all, thanks in advance for any help or tips you can provide! I did a search and found one thread from selveral months ago that asked a similar question, but no one had responded.
I have a Gear S that a family member purchased in South Korea directly from Samsung. It works great when it's connected to my phone, but I'd like to use it as a standalone device, preferably on Verizon. Verizon said their system doesn't recognize the IMEI so they can't add it to my account, but that I might be able use an already activated SIM card.
Unfortunately I don't have any devices that use a nano SIM like the Gear S, so doing this would be some hassle, and I want to have some idea that it would actually work. Looking around on line, it appears there may be a issue with the frequency band used by the watch and that used by American carriers, but I can't tell for sure if this is an issue for this device or whether it is surmountable.
Is there any way to get my watch to function as a standalone device on a US carrier? Can I use it on Verizon? If so, what steps are necessary?
Model number: SM-R750
Software version: R750XXU1BOG1
You have two problems here:
1. Gear S is dual-band only. Only US version will work with US carriers. Rest of the world use the entirely different bands.
2. Verizon is a CDMA carrier. It still uses CDMA for voice, text and 3G data. Only the LTE data uses SIM card. Verizon's version of Gear S doesn't use SIM card at all. So, even if you get a compatible US version of S, unless it has Verizon name on it, it won't work.
Hi guys,
I rooted the phone, installed audio and viper mod... but the only reason I even got that far was trying to root the phone to get additional bands added to the modem. Seems like I am not getting far lol.
The ulefone power 3s I got does not work in canada for bell... as it lacks 3g apparently and only has 2g and 4g? 4g data works, calling phone with 2g works. So data works for bell mobility and rogers, but voice and sms does not work with bell mobility... only with rogers/fido/koodo.
I am going to switch to rogers from bell due to better cost (45 a month plan with data) vs 80+ with bell... so ill get voice working but im worried then how much this phone will work when roaming in the states and what have you....
I seem to be only able to find how to edit bands with qualcom based phones but ours is a p23 or mtk 6763 processor phone.
Did you figure this out?
Just wondering if you were ever able to unlock the bands. I am having a similar issue
Fault of the smartphone made in mediatekļ¼
The japan domestic carrier company where iPhone is set to use all of carrier bands in Japan merely hangs SIM lock and sells a terminal, but even which carrier is available if I cancel it.
However, there is no human being who wants to use this even if the phone which is how much which is the phone which is usable only in Japanese Tokyo where only a measure band of 3G and the LTE is usable because it is sold domestically without most of the carrier bands in Japan being available is bargain as for the smartphone made in mediatek
Even if the person buying it appears if baseband sets it freely and can add it, such an application does not exist.
Because I get the root right, in z3c of sony where band addition is possible freely by QPST and QXDM if it is a phone of snapdragon, there are still many users
The smartphone made in mediatek is a really useless (not smart) phone in Japan
