Hi there everyone,
I have a unbranded Aussie GT-I9100 that i bought in cambodia and use it alot here. But when i go back to the USA for a visit i plan on doing some travelling around and want to know if flashing a USA modem pack would allow me better to access more of the GSM networks in the US? I know several networks run on either 1700mhz or 1900mhz for 3G/HSPA+ and this phones modem is not setup to allow access to those frequencies for 3G/HSPA+ . Or is that just how the hardware is setup?
Thanks for the help
Shawn
The phone won't be able to use frequencies the hardware doesn't support full stop. No flashing of modems will change that. Choose a carrier over there that you know uses the frequencies the phone hardware uses (or you might be left with using 2G or even have no connectivity). The I9100 was never sold by carriers in the US (there are no specific US stock roms & bundled modems that you know will work), so you might end up having to experiment if you get poor connectivity with the modem you're currently running. Might want to download as many modems as you can get your hands on before you go & take them with you.
But best advice is as above, choose a carrier that uses the same freqs as the phone to avoid teeth gnashing.

So I purchased a UK unlocked Touch Pro and had it shipped to the US. While I hope there will be an ATT radio rom flash in the future, I have a quick question for the veterans out there:
On the Touch Pro, under the Phone Band settings, you can select "GSM(1900+850)+UMTS(1900+850)"
When I do this all I receive is Edge on ATT, but aren't the UMTS bands correct already for ATT under this setting?

Thanks, I appreciate the reply, but I had read through that thread. I understand that the device is likely in need of a reprogrammed ROM to activate the hardware because at the end of the day it is not working. My question is specifically if the phone setting is allowing me to select the two ATT UMTS bands already why wouldn't I get 3G speed?

I have the UK version of the phone as well and I have the same issue. I have selected the right bands for both UMTS and GSM but all I get is EDGE. The reason for this is either a hardware limitation (no radio antenna to support 850/1900 UMTS bands (let's hope not) or the factory installed radio firmware does not include those bands or all those da#@ iPhone 3G users are hogging all the UMTS bandwidth . Hopefully all we need is to flash a new radio or ROM to unlock these bands. Just because you can select this band in phone settings does not mean the radio or hardware support it.
I guess I am crossing my fingers along with you . Thanks!

Even though this is for T-Mobile im sure if tmo gets unlocked att will to. Watch that and post there if someone cracks it they will post on that thread.
I have a question for the guys only getting EDGE when they have the correct bands set.......do you have a 3G enabled SIM card? (aka a USIM, some networks require you use one for the 3G to be utilised correctly).
Hi, in answer to your question, yes I have a 3G compatible SIM. I literally plucked it out of my TyTN 2/ TILT and put it in to the Touch Pro. The Touch Pro automatically found the ATT network, and when I went in to check bands I realized that there was an option for the US UMTS bands. I am guessing that others have been right when they have stated that just because there is a menu option it doesn't mean the radios are properly enabled.

So currently you are using a HTC branded Raphael? Could you post your ROM/Radio details? (device info in settings/system) Also your ROM build (settings/system->about)?

I have a 3G enabled SIM, been using it with the Kaiser for the past year with good 3G reception. I now have the HTC branded Raph (UK version) with no 3G reception, only EDGE. Here's the info on my ROM/Radio:
ROM: 1.90.405.1 WWE (8/1/08)
Build: 19965.1.2.3
Radio: 1.02.25.19
OK so it seems the only radios actually in these Raphaels at the moment are all 1.02.25.19, once we have a decent way to flash a different radio stack to it we can see if it makes any difference both in the bands available and some of the reception issues we are seeing so far.
I'm not an expert in this area at all, far from it, but but was reading Black's post about his AT&T model and he has 1.01.25.16. Is this what you're going to flash it to once the HardSPL is completed given that you know his radio supports AT&T 3G?
I'm trying to keep up...
Has anybody heard an ETA for Hardspl? I know they where testing it. But any rumors on a timeframe?
My new UK Touch Pro (radio ver 1.02.25.19) is exhibiting this same behavior on AT&T... I have tried all combinations of those dropdowns under phone options without any luck. It does seem very strange that HTC put the US 3G bands in the band dropdown, but included radio software that doesn't support it...
... Why would HTC bother removing hardware supported bands in the software?

Because they couldn't get it working well enough in time for the release date, I guess. Similar to what appears to have been the case with the Diamond. The US isn't their main concern at the moment, so delaying a US-compatible version for now in or der to get it to the rest of the world on time.
Either that or it's deliberate act to slow down the grey imports until they do a proper US release in hand with the local carriers.
If AT&T doesn't want to subsidize the Pro/Diamond, HTC doesn't really have to worry about putting in 1900 support. And honestly, AT&T is too busy with the iPhone 3G to care about HTC.
On the other hand, I'm sure HTC is very interested in getting in on T-mo 3G (1700/2100). By downplaying 1900 (which is being eaten up by the iPhone, anyway), HTC can gear up for the fresh 1700/2100 band. Paired with Android, HTC could potentially gain a big chunk of US 3G networks.
I'm a touch pro user in Canada on the Rogers network. I too hope that HTC releases a radio that allows 3g network access. I don't think its a hardware limitation because it wouldn't really make sense to make two versions of the same phone just to disable parts of the radio.
I disagree with the statement that AT&T is too busy with the iPhone 3G to care about the Touch Pro. The fact is that the target audience for the two phones are entirely different and that a considerable amount of AT&T corporate customers still require their employees to use PPC based phones (even if the iPhone 3G supports email push).
Corporate standards don't usually move as quickly as they should, so of course AT&T is interested in extracting more money from customers that purchased a Tilt over the past 8 months and want to upgrade, but are not allowed to use an iPhone.
If HTC removed support because they were unable to get the software functioning properly, I can live with that. EDGE for a few months while HTC readies a new radio software package is fine... EDGE while HTC readies new hardware is not.

If AT&T weren't interesting in pushing the Touch Pro, HTC wouldn't have went to the trouble and expense of making a specific hardware revision (PTT button) for them. That's not something HTC are gonna do just for the hell of it on a quiet Sunday afternoon.
Maybe I didn't read the thread well enough but did you try and flash the AT&T ROM that was posted? Maybe that might work!
I have seen many Thread about I9000 trying to convert T959 modem to use the T-mobile network. What i couldn't find is from T959 to I9000 to make it to the international version.
I have the T-Mobile Vibrant T-959 unlocked with ECLAIR. I know that the network band of this phone is 850/900/1800/1900. i found the result according to Samsung website. I know in another post it was said that it is hardware issue but the hardware is 850/900/1800/1900.
I live in the United Arab Emirates and the network band here is 900/1800 similar to the European or Asian Network. but the T-mobile uses 850/1900 so i couldn't get 3G or any kind of internet connection here, unless i find a WiFi connection. I need the 3G connection on the move.
I want to know is there any way to change the the modem band to I9000? so that i can use a custom rom like Darky which is Stable according to many users.
I would never be using the phone on US T-mobile or any Network in the US.
You might think this Question is redundant and has already been answered but i search every where but it comes back empty.
Your feedback would be highly Appreciated!!!!
I don't think you can actually change your phone's bands.
However, an unlocked US T-Mobile Vibrant should be working on 3G. According to Wikipedia, the two 3G networks in UAE (du and Etisalat?) use the 2100MHz band, which should be supported.
Thanks for the reply, i tried everything but nothing worked.
One more question to ask, what will happen if i flash i9000 rom and radio on a T-mobile phone. Or should i just flash it with a T-mobile rom without changing the radio, and if the sim gets locked I will just unlock?
this is the final question to ask.
Don't know if this helps but I use my unlocked vibrant in the uk, so if European bands are the same...it should work.
You can change roms and I would recommend you should but you can't use an i9000 modem.
Do you have a Sim with a data plan?
Can you text or make calls?

Yes i can make a calls and send Text but no internet connection. I just bought data plan for my sim.
So i Should get Vibrant custom rom not the I9000 rom?
And thank you Guys for your replay, I hope this tread will help other confused users on XDA
I would like everyone to know that it is not good thing to change there modem from T959 to i9000 your phone will brick never do it.
I just flashed a new rom from Trigger 3.2 which upgraded to Froyo 2.2 and i put in the settings for the Access Point and it works perfectly.
So if you have any difficulty accessing 3g or HSDPA connection on android 2.1 just upgrade it and it will work.
How did you conclude you're not on 3G? Do you get EDGE or GPRS internet connection?
So i need the 1800 mhz how can i do?
Flash a i9000 modem and see if it works.
Sent from my GT-I9000 using XDA Premium App
There is the possibility to brick the phone?
I bought my Atrix when I was in S.Korea
Now I am in Thailand. There are two network signals for 3G here, 850MHz and 900MHz. I checked the Korean Motorola web site and found out it only supports 2100MHz.
Korean version doesn't have a radio function either. Some said actually it supports radio too but somehow users cannot use and find it. Coz telecommunication companies in Korea don't want people use the radio for free. so they blocked it.
(Radio application costs with 3G usage and it profits them)
Probably they don't want user bring out his phone outside of country also.
It's so ridiculous. Korean Motorola modified its tech spec for just Korean user?
I guess they restricted (or blocked) functions by using Korean firmware. you guys think it's possible? Should I change my firmware to use?
If any help it will be appreciated.
(I suck at English hope you understand what I ask)
Atrix does not support fm radio. A chip on board does, but the connections are not made on the motherboard.
i believe he refers to radio baseband software like ATT as N_01.77.36P and bell as some other kind. also tried 2 different radios and cant get it to work . remember to back up by CWM rom manager before you change anything. i also have a korean atrix i was just trying so see if different one will increase speed.

good luck
also u need to have bootloader unlocked and rooted
first off i know the seniors are going to start *****ing at me for starting a tread when there is like 6 already. But this is different for many reasons:
1. bell galaxy s II i9100M does indeed support 1700 / 2100 UMTS as stated both in the booklet, and also on their webside. I own one and was wondering which modem file would allow those frequencies and how would i get it working with Mobilicity & Wind.
thanks in advance

Wind & Mobilicity use AWS frequencies (1710–1755 up, 2110–2155 down) these are generally not supported by Bell Mobility branded handsets as Bell does not use these frequencies, the phone you linked is capable of the same frequencies as the GT-I9100M other than LTE and the GT-I9100M is not capable of H+ or 3G speeds on Wind or Mobilicity, in order to get 3g/H/H+ speeds on Wind or Mobilicity you would need an AWS capable phone (ie one from them or T-Mobile USA).

That's true, but it doesn't matter for his particular question, the model he linked wont work on the network he wants to use it on either.

Hi, sorry to jump into this thread, but I would like to know f you went ahead with this phone into Wind service and if so, how did this work for you?
I started a thread and some body there told me maybe better to ask in these two threads... my problem is explained here:
http://forum.xda-developers.com/gala...1/post54374435
Thanks a lot for any contribution to my solution.
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.....
