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.

While I was working in Korea, I bought a Galaxy s3 SHV-E210 (Korean Model) cell phone. When I bought, I was told that I would be able to use it over here in the States. AT&T was able to put a sim card and activate it on their network, however I only get 3G. The Sales rep told me that the bands for 4G/LTE are different in Korea than stateside carriers, so I may, or may not pick up 4G/LTE. I've done some research and found that the band in the phone can be changed using certain codes. When I enter *#9090# it brings up a menu, I've tried changing some of the 4G/LTE, 3G options in that menu but I never get 4G. I know how to root and put custom firmware on devices, so if that is something I need to do then I am comfortable with that. Can this phone be changed to get a 4G/LTE signal? are there any more "codes" that I can enter in to get any other options that will help me? has anyone here ever change the band on their phone to work on 4g? Thank you for any and all help.
AT&T uses LTE band 1 for service.
since E210S only supports band 3 and 5, and 3 and 8 for E210K, there's no way to access AT&T LTE network with your device.
It is reported to support band 1 for newer devices like S5 and G3 and AT&T LTE devices might work in Korea since May 2014,
LTE won't be available with Korean S3 in US.

its working for me after covert the the os to international version
I'm sorry in advance if this is a stupid question, but I can't seem to find an answer anywhere.
I bought the unlocked XT1527 from Amazon.com thinking there were a lot of bands listed and it would likely work wherever I went. However, in Singapore, with M1, it almost exclusively connects at 2G, though sometimes shows me LTE. In the UK on Three, it won't connect to anything at all.
Is there any way of changing this up with software or do I just need to get a new phone?
All you need to do is match the bands of the phone with the carrier you're going to use. Check that the Moto features the primary frequencies, but non-US countries usually have very different LTE/Hspa bands.
I just unlocked my gear s with by code
Its not asking about network code again when i insert any sim card
But there is no network signal
I went to serch manual for signal operators but still nothing appears
Can you help me

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.
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.....
Dear,
Apologies if I put the topic in the wrong place. I bought the LG V60 in a European web shop. (alza shop) But the problem arises with the 5G network the device simply does not have the option "5G network mode" There is only automatic and 2G 3G and LTE. I contacted LG myself and got the following answer.
"There are technical dependences here. These dependencies are different per country.
The V60 is 5G capable (for a limited number of bands though) but it does not work for all providers in all countries.
This depends on the V60 suffix as well. If 5G could not be fully tested for a specific provider it is sometimes switch off in software.
In the Netherlands for example 5G on V60 only works for the KPN provider at the moment (Android 10).
If you put in a different SIM card (so not KPN) the device will not show the 5G option.
This situation will change in the future with SW update"
Is there help here and does anyone have any information related to this? Has anyone had a problem like this and has solved it without waiting for the software update ?

Hi!
In Switzerland is the same: the v60 has 5g active only for swisscom operator. I have it now with yallo/sunrise network and it doesn't show any 5g option.
I tried to flash stock rom from poland but still no effect. Probably the limitation is on the radio part of the rom.
Maybe someone here with more knowledge could shed some light on what is the best approach to take...
I was wondering if just by simply unlock the bootloader (now possible on the european version of the v60) we could get a workaround for unlock the radio limitations...
