Hello.
I have a Moto e 2015 XT1524 that works fine in Spain, but the 3G and 4G bands are different in Argentina and I want to use this device there. In Argentina the model they sell is the XT1527.
The question is if it is possible to flash a XT1527 firmware in a XT1524 model in order to use the Argentina bands or this models have differents hardwares for the radio bands?
Thank you very much
From: gsmarena This are the bands of the different Moto E 2015 models:
3G bands HSDPA 850 / 1700(AWS) / 1900 - XT1527, XT1511
HSDPA 850 / 900 / 1900 / 2100 - XT1505
HSDPA 900 / 2100 - XT1524
4G bands LTE band 2(1900), 4(1700/2100), 5(850), 7(2600), 12(700), 17(700) - XT1527
LTE band 1(2100), 3(1800), 7(2600), 20(800) - XT1524
Spain:
3G capabilities - UMTS 2100
Argentina:
3G capabilities - UMTS 850, UMTS 1900
4G capabilities - LTE 1700, LTE 2100

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...
I´ve also published this post in Grupo Android (spanish version).

Hi guys,
I have a strange problem, I guess.
I bought my HTC Desire 610 on amazon. It is AT&T.
I use it in a different country with GSM sim. Everything seems to work fine. I am connected to 4G network if I am in 4G coverage zone. But when I dont, it won't switch to 3G, it just goes offline.
long story short: 4G seems to work, but 3G don't.
network mode is set to WCDMA/LTE Auto.
could anyone help?
I think this is something to do with the Rom, if you were to install the cyanogen mod or the slimkat Rom, 3g works just fine in both, idk why though

I Installed GSM signal monitoring application. As it turns out the phone only receives HSPA+ (3G) signal, but somehow thinks that it is 4G. Because 4G is displayed on top of screen. that is why I thought it was working on 4G network. but now I guess it works on 3G but thinks that it's 4G
now I want to enable 4G but have no idea how

Depending on what country you are in 4g probably won't work with an at&t phone as the different variants have different 4g bands unlocked in the radio firmware and probably antennas. See the following extract from desire 610 network specs. US 4g bands are quit different from those available in most regions.
NETWORK Technology
GSM / HSPA / LTE
2G bands GSM 850 / 900 / 1800 / 1900 - all versions
3G bands HSDPA 850 / 900 / 2100 - EU, EMEA
HSDPA 850 / 1900 / 2100 - AT&T
4G bands LTE band 3(1800), 7(2600), 8(900), 20(800) - EU, EMEA
LTE band 1(2100), 3(1800), 7(2600), 8(900), 28(700) - Asia
LTE band 2(1900), 4(1700/2100), 5(850), 17(700) - USA

Yes. I guess you are right.
So there is no way to fix this?

Its hard to say for sure. Try a ROM from the region your in or cm11 which is for all regions. This probably won't work but is worth a try. Otherwise to that you would have to go s_off with sunshine (costs $25) and flash changes to radio firmware( either someone's dump from a phone in the region your in) or modifying it (google "XDA qcom unlock radio bands) but either way it's very risky unless you really know what you doing you can easily end up with an expensive brick and it still depends on whether you phone is equipped with a suitable anttena for the frequency the band your carrier is using.
Hi, last week I was given a Moto G3 XT 1541 from Spain. The problem is that it doesn't connect to argentinian carrier's 3g or 4g bands, it only works on 2g. A friend told me that I could work it out flashing the firmware of another model like XT1540 which works perfectly on 3g and 4g. Is it a firmware block? Can I solve it flashing another model's firmware? If I flash it, will my phone work or it will be a stone? Thank you ver much.
Yes, you can.
Moto G 3rd generation does not have capability of 2300 MHz bandwidth.
Requirements for a4G
1. A handset that supports 2300Mhz.
2. A 3G plan.
3. USIM (they provide free upgrade)
4. 4G network coverage
I think even HSPA or HSPA+ might not work for me on this phone. I am using a T Mobile family plan here, and comparing th bands given on the website:
"4G (HSPA+)
With 4G, theoretical maximum download speeds range from 21 Mbps up to 42 Mbps. You can take advantage of incredibly fast download speeds, and even use voice and data services at the same time.
Frequencies: Band 2 (1900 MHz), Band 4 (1700/2100 MHz)
3G (HSPA)
With 3G, theoretical maximum download of 14 Mbps. With 3G, you can use voice and data services simultaneously.
Frequencies: Band 4 (1700/2100 MHz)"
"Moto G (XT1550)
LTE (1, 3, 7, 8, 28,40) UMTS/HSPA+ (900, 2100, 850 MHz)
GSM/GPRS/EDGE (850, 900, 1800, 1900 MHz)"
It seems that the uplink is unsupported by my phone and so the phone is unable to use the HSPA/HSPA+ bands. I think the only way to use it is to unlock the 1700 MHz band on my phone.
XT1541: GSM/GPRS/EDGE: 850, 900, 1800, 1900 - UMTS/HSPA+: 900, 2100 - LTE: B1 (2100), B3 (1800), B7 (2600), B8 (900), B20 (800)
Argentina UMS/HSPA+ works on 850 and 1900.
This phone will only get 2g where you are. Flashing another firmware will not fix this.
I have a new unlocked S9+ China (SM-G9650/DS, Qualcomm Snapdragon 845), and I'm trying to figure out if it is fully supported by T-Mobile in the US.

Can someone confirm or comment whether the phone is fully supported, or if not what's missing? Thx, Gus

It will work on T-Mobile frequencies but you won't get Wifi Calling or voLTE. The stock CSC is TGY - Hong Kong, T-Mobile is TMB. I haven't found any way to change the CSC even with custom ROM, but assuming one became available you would trip Knox and lose Samsung Pay, Samsung Health, Secure Folder, OTA Updates and Factory Warranty. Some members have posted in regards to changing the CSC Code in the link below but I'm not certain it's working out. Good luck!

baring any unforeseen hidden stuff, you should be good to go for Tmobile...Minus the new Band 71 on the 600mhz spectrum. Honestly, unless you live in the area that will get this deployment, this shouldn't be of concern. As long as you can use Band 2/4/12, you will be ok with Tmobile.
I almost went with this route as well since I wanted to get a Snapdragon version with larger storage size. But I chickened out because I've been reading people having bad signals/not having full LTE speeds with their imported S9+ on TMOUS.
Good luck and let us know!
I used CT Excel Americas (T-mobile mvno) and it worked on CHC firmware. But I forgot to test volte etc.

Please post steps for this. I would like to get VoLTE and Wifi calling
