Is there a way to enable the 1700 MHz band for T-Mobile's 3G network for the i8190? There is (or going to be) a T-Mobile variant of this phone called the Galaxy Exhibit, but I don't know if it uses the same modem. If it does, is there any chance the Galaxy S3 Mini could support T-Mobile's frequencies? From what I understand, I would need to flash the appropriate modem firmware.
Thanks!
Hi,
I'm a huge galaxy fan since I've had the Galaxy S 4g (T959V) for over two years and it has been through hell but keeps working. I rooted it and loaded custom rom, kernel and modem so I do know a little about smart phones. Now I want to buy a new galaxy, but the s4 apparently is very fragile, so I turned to the S3. I jumped at the chance to buy a 9305 with 2 gb ram and quad core processor, but now I'm not sure that was a good idea, since I have T-Mobile and apparently their bandwidths for 3g and 4g are not compatible with i9305. Is there a way in all this rooting and flashing to change the bandwidths that the i9305 uses?
I9305 Specs:
2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 850 / 900 / 2100
4G Network LTE 800 / 1800 / 2600
From TMOBILE:
T-Mobile 4G LTE
T-Mobile’s 4G LTE network uses 1700 MHz and 2100 MHz frequencies. You'll need a phone that supports LTE 1700 MHz and 2100 MHz frequencies.
T-Mobile 4G (HSPA+)
Our 4G network operates on the 1700 MHz and 2100 MHz frequencies. We use 1700 MHz and 2100 MHz frequencies to use voice and data services. You'll need a phone that supports 1700 MHz and 2100 MHz to connect to our 4G network.
Use voice and data services at the same time.
T-Mobile 3G (HSPA)
Our 3G network operates on the 1700 MHz and 2100 MHz frequencies. You'll need a phone that supports 1700 MHz and 2100 MHz to connect to our 3G network.
Use voice and data services simultaneously.
T-Mobile 2G (EDGE)
EDGE, our enhanced 2G service, delivers a theoretical maximum download speed of 236 kbps.
GPRS, our 2G service, delivers a theoretical maximum download speed of 114 kbps. Typical speeds are between 35 kbps and 45 kbps.
Voice and data services cannot work simultaneously when on GPRS or EDGE.
I'm getting a bad feeling that this phone is not going to work well with tmobile 3g/4g without some heavy modification. Any advice welcome!
The bands depend on hardware, so no you won't be able to use the international s3 late version on t mobiles late frequencies but 3g will work as both use 2100

Hi All,
Just knew today that my unlocked HTC One M7 is not compatible with LTE signal with my local carrier (Smart PH) as stated here.
Further checking, the carrier is operating in LTE in these bands:
Band 1 – 2100 MHz
Band 3 – 1800 MHz
Band 5 – 850 MHz
Is there anyway for my phone to be able to connect in LTE? Will rooting my device fix the issue?
Thanks!
I wanted to get the t-mobile version and use it on AT&T. Does anyone know if I will have trouble unlocking it or have any issues using it on AT&T network. I have unlimited data so I want to be able use hotspot option. Also, the box is hideous on AT&T.
My understanding is that all carriers got the same variant. Should have no issues, except maybe Wi-Fi calling being weird.
dont do it.
The tmobile and att use different brands so while it will work on the network the internet will be slower.
unless this has change but from what it has always been is the network brands where different and some people where not able to get 4g lte

I think they all have the same exact hardware. Someone on the Verizon forum took a Verizon phone and flashed the T-mobile firmware and it works perfectly. (I may have those carriers mixed up but you get the idea)

No no firmware is software base.
Im talking about network mhz Frequency.
If i remember right tmobile was 900mhz 1800mhz and 1900mhz
And att was 850mhz 1700 and 1900.
They used different bands for internet. So must people who switch couldnt get 4g internet.

I understand thank you. And what I am saying is I think they all have the same bands/hardware and just need a flash to unlock it all. Aka the pit file and bootloader.

Please read my previous post carefully and then click the link I provided. I am not arguing that the carriers use different bands.
Yea my bad didnt see the link you posted. But yea of the phonne has them build in just turn off that will work.
Before the phnes themself didnt have the bands
I have unlocked (SIM) my note 7 and it works great on AT&T. I tried a Sprint SIM and it wouldn't work. I even went to Sprint store and they tried to enter the IMEI in their system as a BYOD. Didn't work even after they tried adding it through their CS Techs on the phone. The T-Mobile version does not have the CDMA radios active. I haven't tried to flash it to Sprint to see if the Sprint ROM would enable the CDMA radio.

You should try. Apparently it will work.

Awesome! How did you unlock it so soon? I thought t-mobile policy is to wait for 45 days
Can you flash non native ROM with locked bootloader? or is it just flashing modem ok?
So when the unlocked sm-n930u version is released, will we be able to flash that firmware on our phones? Allowing us to remove all the carrier bloatware that was installed.
