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

Got bored and did some research...baked into the software is the bandwidths across the holiday and carriers specific phones...since we are not able to flash radios...this is becoming an issue for a lot of people....so heres what I found thought was interesting...these are controlled by the radios which for now we are not able to flash so until we are able to flash,signal issues will be a factor...
Rogers HTC Raider LTE Specs

Telstra Bandwidths
Telstra will sell dual mode LTE/HSPA+ mobile broadband devices that will operate seamlessly across 1800MHz and 850MHz spectrum bands, giving Telstra Next G network customers the benefits of 4G where it is available and then seamless switchover to the 3GHSPA technology in other areas.
SK Telecom
LTE 850 mhz

No issues, You just have to modify a few files in any SKT or AU based rom.
Battery drain though.... That is another issue & will continue until we get a solid custom Vivid based Kernel that uses Vivid voltages instead of using the Raider Voltages, which as you know, uses a different processor than the Vivid.
Rogers raiders is the same as at&t vivid. The raider in Korea runs differently. Right now we are using 1700/2100 for lte service until the 700 auction can be completed. Then we will use 700 band.

I cant find any way to get 3g, i only get GSM, which sucks. these are the frequencies in my country for 3g 850 900 2100
any chance i can get it?
thanks in mind for helpers

The Sprint model can connect to the following frequencies (link):
2G/2.5G - GSM/GPRS/EDGE: 850/900/1800/1900 MHz
3G - UMTS/ HSPA: 1900/2100 MHz with HSPA+ up to 14.4 Mbps
3G - CDMA: 800/1900 MHz for Sprint
4G - LTE: Sprint: 1900 MHz

I'm assuming that when you say "3G," you're referring to HSPA and when you say "GSM," you mean 2G/EDGE. This means that the Sprint model can only connect to the 2100 MHz frequency in your country for 3G. I don't know how it works in your country, but in the US, some carriers only transmit on certain frequencies in some markets (areas). It may be that your carrier is not transmitting 2100 MHz in your area.
For example, in the US, T-Mobile transmits 3G on 1900 and 1700/2100 MHz. However, it doesn't do this everywhere in the country. In some areas, it will transmit 3G on all of those frequencies, but in other areas, it might only transmit on 1900 MHz because it doesn't have the license to transmit on 1700/2100 MHz in that specific area.
Basically, you need to find out if your carrier is actually transmitting 3G on 2100 MHz in your area. What country are you in and what carrier are you using, just out of curiosity?

thank you for ur response, and no i figured out what the frequencies are in my country, and they are listed above,
but either way i live in israel and my carrier is youphone which works on orange network.

if yiu use GSM sim, indicator show GSM.. maybe on youtube use another cdma carriers. mine if use gsm sim show GSM, when use CDMA show 3G
Does the d4 use both 2100 and 900mhz 3g bands (europe) ?
I'm thinking of importing one or the samsung relay 4g, but do both smartphones work at 900mhz (much stronger signial here) ?
up
Not sure about that, but I can confirm you that 3G works perfectly in Spain with this mobile
Here are the bands supported.
2G Network CDMA 800 / 1900
GSM 850 / 900 / 1800 / 1900
3G Network CDMA2000 1xEV-DO
HSDPA 850 / 900 / 1900 / 2100
4G Network LTE 700 MHz Class 13
I have a Droid 4 in UK, and I can confirm HSDPA is working, but couldn't go higher than that, probably 4G is working only on 700 MHz, which no operator has in UK: hxxp://en.wikipedia.org/wiki/List_of_LTE_networks#Europe
I have a supposedly "unlocked", RAZR i , however it won't work on any network other than T-Mobile. I've been told T-Mobile UK Motorola Razr I supports T-Mobile UK's network frequency of 1800 mHZ, but, Vodafone, O2 and 3 use an updated 4G network that runs on 1900 & 2100 mHZ. Is this correct and is there any way I can use the phone on the 3 network.
Thanks in advance....

Razr I should work on the following frequencies:
2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 850 / 900 / 1900 / 2100
The device doesn't support 4G. So if the providers can give u 2G or 3G on those freq u can use them.
I got this as a gift for my daughter and now all I get on TMO is 3G Edge. I am in Maryland, USA. I thought this thing was supposed to support a bunch of LTE bands but I don't see many matches for either TMO or AT&T. I've tried various APN settings to no avail. Someone suggested flashing a new modem to unlock the 1700 band but I cannot find anything on that either. Am I stuck with a 2G BRICK??????
Please help!
Chris R.
Stay close to WiFi! I'm afraid that you may have yourself a '2G brick'. It would appear that T-Mobile in the US use the following frequencies:
LTE Frequencies (FDD LTE, not TDD LTE)
1700 MHz & 2100 MHz AWS band 4
1900 MHz PCS band 2 (in refarmed areas)
Lower 700 MHz band 12 (in development)
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
The only band from this list that the M2 supports is 2G 1900 MHz. The 1700 MHz & 2100 MHz band is an upload/download pair and is different from the 2100 MHz band used in Europe (the one the M2 supports), which is actually a 1900/2100 up/down pair. I'm fairly sure that frequency support is a hardware thing, it's not possible to change supported bands by flashing a new radio module.
It's unfortunate for those of you in the US that Chinese phone manufacturers seem to favour the EU, rather than US, frequencies.
Thank you!!!!!

Thank you for your brilliant and most useful reply!!! Much appreciated! The M2 is now for sale up on Ebay and I just bought a Cube T8 Plus tablet that has phenomenal specs but it too has the wrong frequency support so I'm about to put that up on eBay as well. Thanks again!
