[Q] Can you change mobile data bands in your smartphone? - General Questions and Answers

Hi all, I just realized I made a mistake when buying a smartphone abroad. I got a MotoE 2nd gen XT 1524.
This are the bands that work in my country:
2G: 850 / 1900
3G: 850 / 1900
4G: Banda 4 (AWS, 1700, 1700/2100*) / Banda 28 (APT700, 700 MHz**)
And these are the bands my phone has:
LTE band 1(2100), 3(1800), 7(2600), 20(800) – XT1524
HSDPA 900 / 2100 – XT1524
2G bands GSM 850 / 900 / 1800 / 1900 – all versions
I know, I'm in trouble. But my question is... can I try something before starting to cry? :crying:
(BTW, I'm suuuuuuuuuuuper begginer, it's my first real smartphone, I had a feature phone before this one)
Thanks!

Hello!
I had a simillar problem with the XT1524. I also live in Argentina.
The XT model is international, so at a hardware level you have all the bands, but it is limited by the software.
The solution is (tranks to JasonPro11):
1. Download "4G LTE Switch" from PlayStore.
2. Run the app (does not require special permissions).
3. Go to "Set preferred network type” and choose LTE/GSM.
4. In the upper corner go to "Set Radio Band" and choose "USA Band".
5. Restart and enjoy LTE and 3G in Argentina...

[Q] Using 3g Argentina (Movistar) [WCDMA 850?]

Hi! I've bought this phone (SGH-T959V) from T-Mobile on USA, and when I went to Argentina, I found that the carrier that I have (Movistar) mixes the frequencies or something like that.
It uses GSM 850 / 1900 and UMTS 850 / 1900. By default, my phone can't use 3g (neither HSDPA) from this carrier.
Dialing *#*#197328640#*#* And going to Network Control > Band Selection, I can choose which frequencies to enable / disable.
If I disable GSM 850, and enable all the rest, I can get to use 3g on the 1900 Mhz, but I get much lower signal.
The frequencies that I can enable / disable from this menu are:
GSM 850
GSM 900
FCS 1800
PCS 1900
WCDMA 2100
WCDMA 1700
WCDMA 1900
I don't know how this works, I want to use my phone and be able to use 3g / HSDPA / HSDPA+ / 4g if possible..
I think that I need to find a way to enable WCDMA 850 on my phone.. Is it possible?
I am using the last upgrade from Kies (Gingerbread) 2.3.6
Do I have to flash a new modem? I've searched for available modems for this phone, but none of them say anything about enabling WCDMA 850 frequency
When I go into Settings - Wireless and network - Mobile networks - Network mode it has a GSM/WCDMA (auto mode)
Have you tried that?
Yes, I've tried that, that option is enabled!
In the GL9003L model (Samsung Galaxy S too) from this country, the WCDMA 850 option is enable (also the WCDMA900). Isn't there a way to add that frequency to my phone >.< ?
The hardware doesn't support UMTS 850 which you said is used by your carrier's 4G. You won't be able to use this phone on their 4G network.
Buh, so there's no way to change the frequencies it uses?
Sucks I can't use 3g (not 4g, 3g!!!) on my country
No you won't be able to. According to this page, these are the frequencies available on the phone:
http://www.gsmarena.com/samsung_galaxy_s_4g-3719.php
2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 1700 / 2100
Click to expand...
Click to collapse
Your network will have to be running on exactly those frequenices to get 3G/4G
I think that is wrong.. I have another carrier that works on the 850 / 1900 band and I CAN user their 3g (mostly because I can connect to the 1900 band..), but I can't use HSDPA+.
So:
with one carrier, Movistar, that uses UMTS 850 / 1900 I can't use 3g, it only connects to the EDGE network, and when I dial *#0011# with the GSM bands disabled it says that the 3g service is limited and I can't use it at all.
With the other carrier, Personal, that uses the same bands, I can use 3g on the 1900 band, but can't use HSDPA or the 850 band.
Also, from the #*#*193728640#*#* menu I can choose the UMTS 1900 band.
I've a similar problem the difference is a got 3G but not 4G and can't figure out what is going on. I'm with digicel and the only use 1900 wich is already enabled. I once tried movistar and had the same problem I suggest you another carrier
This's my problem:

Do not trust phonearena as it has wrong information about our device frequencies that it can use.
umts 1700,2100,1900
So basically no, you won't get anything else than edge on those 850/900 frequencies.

OnePlus 4G Frequencies

Hi Guys ,
I have the Chinese variant of the OnePlus. I am able to use H+(3g) fine in my country. However i am thinking to switch over to 4G . But i am unsure if it supports the 4g frequency here .
However i just confirmed from my network provider that they are offering 4g on 1800Mhz frequency. Does the Chinese version ( with Cm11s ) supports this ?
Jip the Chinese variant supports 4G / LTE band 3 / 1800MHz :good:
"Network standard:
GSM: 850/900/1800/1900
TD-SCDMA: 1880-1920 / 2010-2025
WCDMA *: 2100/1900/850/900
TD-LTE: 2570-2620 / 1880-1920 / 2300-2400
FDD-LTE *: 2100/1800/2600
* WCDMA and FDD-LTE standard two networks need to use international roaming"
Taken from translated Chinese site here
PS: I have a Chinese Variant running CM11s using LTE (1800MHz) in South-Africa right now.

[Question] Moto G 3rd Gen International Network Compatability

Hi all, I'm considering buying an unlocked GSM Moto G 3rd Gen, and I am trying to figure out how it will work outside the US with other network operators. The 2 areas I am interested in are Hong Kong and Ecuador.
The network specs for the Moto G 3rd Gen are:
Code:
Technology GSM / CDMA / HSPA / LTE
2G bands GSM 850 / 900 / 1800 / 1900
CDMA 800 / 1900 - XT1548
3G bands HSDPA 900 / 2100 - XT1541
HSDPA 850 / 1700(AWS) / 1900 / 2100 - XT1540
HSDPA 850 / 1700 / 1900 - XT1548
4G bands LTE band 1(2100), 3(1800), 7(2600), 8(900), 20(800) - XT1541
LTE band 2(1900), 4(1700/2100), 5(850), 7(2600), 17(700) - XT1540
LTE band 2(1900), 4(1700/2100), 5(850), 12(700), 17(700), 25(1900), 26(850), 41(2500) - XT1548
Speed HSPA 42.2/5.76 Mbps, LTE Cat4 150/50 Mbps
GPRS Yes
EDGE Yes
GSM information from: http://www.worldtimezone.com/gsm.html
China, Hong Kong (SAR):
Code:
900 1800
3G 2100 CSL Ltd; 3G 2100 HKT; 3G 900/2100 Hutchison; 3G 2100 SmarTone;
4G LTE HKT 1800/2600Mhz; 4G LTE Hutchison 1800/2600Mhz; 4G LTE SmarTone 1800Mhz;
Ecuador:
Code:
1900 850
3G 850 Claro; 3G 2100 MOVISTAR;
4G LTE CNT Mobile 1700Mhz;
My conclusion from the data above is:
Voice/SMS/2G Data - Supported in both HK and Ecuador because the Moto G supports all 850, 900, 1800, and 1900
3G Data - Supported in both HK and Ecuador on all carriers since all frequencies for the carriers are present in the phone specs for 3G
4G LTE - Supported in both HK and Ecuador on all carriers because all frequencies listed by the carriers are present in the 4G LTE list
Could someone eyeball these specs and let me know if I'm drawing the correct conclusions or if I'm actually misunderstanding how the bands work?
Any help is greatly appreciated, thanks!
Edit: I was double checking the bands listed on gsmarena, which claims both Hong Kong and Ecuador have UMTS 3G bands. The Moto G specs say HSDPA for all the 3G bands. Does the phone need to have UMTS listed for it to work or are they compatible for 3G?

[Completed] Some help with bands please

I got a V19 phone from china with Android 5.0. I believe it is a rooted phone, I've seen some of those features. It came in a box that says Android. I have no idea of the manufacturer.
Problem: I cant get the data connection (tmobile, wifi works fine) to get better than the edge network, 2G. I've learned that T-Mobile requires these bands:
LTE Frequencies:
1700 MHz & 2100 MHz AWS band 4
1900 MHz PCS band 2 (in refarmed areas)
Lower 700 MHz band 12 (in development) / in service in selected areas
3G/4G Frequencies (WCDMA):
1700 MHz & 2100 MHz AWS band 4
1900 MHz PCS band 2 (in refarmed areas)
2G Frequencies (GSM/GPRS/EDGE):
1900 MHz PCS band 2
Inside the battery area the phone lists :
GSM 850/900/1800/1900mhz
WCDMA 850/2100mhz (HA)
When I got to engineering mode, I can see other bands that are greyed out.
So my question is this. Is it possible to slick this phone and install software, etc, that allows the bands I need? Or are 'Bands" hard coded into the hardware of the phone? Easier to just buy another phone with correct bands? Advice or links?
Thanks,
Gary B.

LTE 700 MHz (Band 28) unlock?

Hello everyone.
Please, I'm searching online for this for days now and can't find anything useful for our Note 3. My carrier uses 700 MHz for lte here in my country and for urban areas it's a must have because of it's enhanced penetration.
So, my question is if the Snapdragon 660 does support this frequency on the hardware level and it's locked just by software or there's no way to enable this ever? And if it's possible, someone knows how to unlock this band specifically? Flash a custom modem or anything? I'm running miui 9.6.2.0 rooted.
And since I'm already here... I can't change permanently the settings in Phone Info (menu *#*#4636#*#*), the preferred network type always go back to LTE/TD-SCDMA/UMTS and I can't enable permanently Volte Provisioning either. It always go back to off.
Any help would be much appreciated.
Thanks in advance.

These are the bands supported by the phone:
2G bands GSM 850 / 900 / 1800 / 1900 — SIM 1 & SIM 2 CDMA 800
3G bands HSDPA 850 / 900 / 1900 / 2100 CDMA2000 1xEV-DO
4G bands LTE band 1(2100), 3(1800), 5(850), 7(2600), 8(900), 38(2600), 39(1900), 40(2300), 41(2500)
B20 (800Mhz) is not supported and is not possible to unlock it.
B28 (700Mhz) is not supported and is not possible to unlock it.

First: if your carrirer doens't support Volte tecnology
Second: if your carrier support Volte then is also necessary that the firmware of the your phone is compatible specifically with this carrier.
If not these conditions then is normal your behaviour
