Has any been able to get 3G to work in the USA yet?
thank you,
jdm
I would say that it is imminent that the US version of the S730 will be released soon. AT&T or T-Mobile may pick it up (T-Mobile's 3G network in NYC just went live, but there are no phones). If so, I would suspect that some of these crafty folks (like Alcaline) would be able to extract the radio ROM, and make it available for the S730 that we all have (the european version).
But, here's the most important part... It all depends on whether or not the European version of the S730 has the radio chipsets that will support 3G on the frequencies that are 3G in the US. There is no known answer "available" to this, so it can only be discovered by testing.
The current S730 uses the 2100 band for 3G speeds and ATT is deploying 3g on 1900 and 850 I believe and they sell a decent ammount of 3g phones. T-Mobile is working on setting one up on the 1700/2100 band but I dont care for T-Mobile.
I have watched my phone at times flip into 3G mode for a few minutes then revert back to Edge, its trying but cant work properly without the right frequencies.
Check out the chipset datasheet. Bottom of page three explains the specific radio chipset combos and their support for different freqs.
I suppose, to save on manufacturing costs, they could have used the single chipset that supports 3G on all freqs (RTR 6285), but I believe this is unlikely due to the difference in model number that was submitted to the FCC (European version: WING220, US version: WING200).
Who knows though.
3G in US
Hermes models had different model #'s HERM100, HERM200 and had the same radios, in some cases minor difference such as case style, i.e removal of video calling camera etc. With any luck we have the RFR6500 + RTR6275 Combo, or as you mentioned the RTR6285 and just not a radio rom that allows 1900+850 3G. I was looking on the FCC site and they have some interesting screen shots, one of which shows one(s730) with what appears to be the front camera covered up and another which shows a radio rom(R 0.27.03.05B), one that, to do the tests would likely need to support 1900+850. Check Page 250 / 11 in the PDF. However, also in the test is the lack of any mention of 2100 Mhz test, which would suggest that either the US 3G Radio won't support 2100Mhz or that it indeed has different hardware that won't support 2100Mhz. At any rate it would be interesting to know if anyone has tried to flash one of the pre-prod roms for the wing 200 onto the wing220 and see if they are able to connect up to 1900+850 3G.

I suppose only time will tell.
Wow... nice investigative work. Very interesting. I'll start hunting around for the ROM.
[edit]
Searched google and, my favorite, napalm with no luck. I wonder if we can lure an FCC testing engineer into the XDA-dev realm. muahahaha
I was searching some of the other posts, and it appears that most of the pre-prod radio rom testing had been focused on GPS functionality. Has anyone been able to throw on any of the pre-prod radios with an ATT SIM and tested to see if it can connect to WCDMA -> US Band (1900+850) ??
I have no possibility to check the 3G in the USA from my location in Norway.
But just to get this clear, because I have changed my Radio more often then most people change their underweare.
Is everybody able to select WCDMA and then US Band in the settings?
I dont know if this is selectable on all devices or if this is made available after my radio flahings.
I believe all S730's have the following options available.
Network Type:
Auto
GSM
WCDMA
Band Type:
Auto
US Band
Euro Band
Japan Band
For it to actually be able to operate on all of these frequencies I believe it would need to use the the RTR6285 chipset as the other 2 combos would not support all of the different frequencies combinations.
US Band -> GSM 850+1900 / UMTS 850+1900 (ATT)
Euro Band -> GSM 900+1800 / UMTS 2100
Japan Band -> UMTS 2100+800 (not positive on this one)
If I change band to from Auto -> WCDMA I do not get an error but no 3G Icon and all calls fail. If I then go and change to US Band while having WCDMA selected it indicates that it cannot change to that GSM/UMTS Band. Also interesting, If I stay on WCDMA and select Euro Band, no error, but of course all calls fail. I then tried to change to Japan Band, no error and no phone calls. Finally I am still on WCDMA and I switch to US Band and I get the error that indicates I cannot change to that band. So, I would be interested to know Alcaline if you see the same behavior on some of the other radios you have been trying to see they allow the switch to WCDMA / US Band combo.
Thanks
Can anyone else confirm this behavior on any of the other Radios out there?

I have the ability to tell my phone I am in the states, but it does nothing (default settings though)
Was the US version (WING200) of this phone ever released? Or has anyone gotten the EU version to work on any US 3G networks? Wondering about T-Mobile...
Hello experts,
Would you please tell me if I need a new modem (currently on T849UVJJB, assuming that's stock modem), or do I just need to carrier unlock my tmobile branded galaxy tab in order for me use pre-paid sim from other countries such as Hong Kong or Taiwan.
I have already rooted my galaxy tab and installed Overcome 3.0.0 on it. I am interested in voice + data, but all these different radios and talks of voice calling is disabled on the tmobile server's side (thus only network unlock is required to get voice +data) had me confused.
Greatly appreciate it if someone can clear it up, thanks.
To use any sim besides t-mobile, you need to unlock.
You will need to root your tab, then unlock it.
Since there is no compatable network in China the best you can get is voice and EDGE data.
Use a froyo modem.
Thanks rangercaptain for your reply.
As I mentioned I have overcome rom installed, thus I am already rooted. I also installed from the market galaxy_s_unlock, and it seems to be working (although I won't be able to find out until later when I travel.)
you mentioned it will only do EDGE, which I am dumbfounded:
-most Asia (including China) and Europe support UMTS 2100, known as Band I
-Tmobile galaxy tab spec page listed it supported both UMTS 2100 (Band I) and UMTS 1700 (AWS)
I am traveling soon so I guess I will report back. But if there is any actual report from users that would say one way or the other it would be awesome.
Thanks.
The word "and" is the key. The t-mobile tab has to have 1700 and 2100 bands to have 3g/H. Outside of US t-mobile service area, the 2100 band is available, but no 1700 band.
Go prepared for EDGE and be pleasantly surprised if you get 3g. It has worked out in a few places.
well, I am at Hong Kong right now, and here's what I found:
I am using hutchison 3G, JPE modem.
Yes I get voice. Data: GPRS works, EDGE works (though most of the time is G)
But whenever the icon indicate 3G (even with 4 bar) I get no data, at all.
Here the head scratcher: When 3G swtich over to the letter H, if it is above 3 bar I can get data! But I thought 3G and HSPA is on the same frequnecy and if it works for H it should work for 3G also.
That's because the bands for 2100 match, and the US 1700 band and the overseas 1900 band have a small overlap, so you occasionally hit the sweet spot.
Hello,
I need help with a Blu WinHD: I purchased one while in the US as a replacement for my broken phone, but once back in Europe I discovered I had no 3G connection.
A quick web search and I found my model variant (W510U) only supports 3G/HSDPA at 850/1900/1700 MHz, while my Italian provider offers 900/2100 MHz bands (Vodafone IT). However, another variant does exist (W510 L), and actually supports 850/1900/2100 MHz.
Since both phones feature the same SoC (Qualcomm MSM8212 - Snapdragon 200), will it be possible to change the 3G band used by my version? I was thinks about flashing the other variant firmware, or trying some dial string and see whether I can change Cell Network settings...
Any tips?

I'm looking for the same
A quick search online gave me this:

You need to be a VIP to download that. But still, I don't know which flashing tool should be used :/
Don't forget to reply if you find anything relevant!

I'm not sure. But the 3G bands always had been a hardware thing. So you can't change it changing firmware or something. It's not like unlock, it just doesn't have them.
@anthonws Wonderful, I'll try to decompile this firmware in order to discover whether there are some dial strings that could help. But of course, being able to flash it at once would have been better. I'll look for any other flashing options as well.
@m1k3_ I was thinking the same at first, but later on I couldn't explain myself how could that be possible with the very same SoC on both model variants: if the SoC embeds the radio controller, what else can pilot the 3G bands? I would have better to get the chance to read the detailed datasheet of the Snapdragon 200...
Unfortunately, I finally got a reply from BLU Support Service, stating that 3G bands are actually hard-coded, so no software change can actually modify them....
I'm very sorry about that, I got to like this phone very much....

I brought BLU HD W510U as well. But my question is : does your W510U have iuminous backlight for back key, home key, search key at night time?
Hi,
I own sm-t715y, samsung website mention the availability of tdd lte band 40, i want to use a provider which is data only, it doesn't have any voice capability (called bolt). And a cdma provider which uses tdd lte band 40 as well (called smartfren).
Most of the tutorial on other devices which has tdd lte band 40 support has these steps:
1. Force lte only
2. Turn radio off and on
3. Set apn
I can't set force lte only on this tablet yet, tried *#0011# and *#2263# but it cant, the 2nd one cannot pop at all, please advice
When you say other device, this isn't Samsung is it.
I also have a S2 with band LTE 40, why don't you just buy a data only sim card, that is what I have 10GB data 1 year time limit.
Yes, the other device is oneplus one, alcatel one touch flash.
I tried experimenting with smartfren but no success at all, have not tried with the data only bolt, the cs said it cant but i doubt its true.
That is why, I had many Samsung, and non of them has lte only.
different phone/tablet has different features.
Unlocked Galaxy s5 AT&T Samsung SM N920A on GSM network.
Stock Rom, Unlocked, on Android 7.0 (updated with Odin)
My goal is to see if this phone can indeed be used on CDMA.
Now let me back up.. I hear you. Most phones cannot be used on CDMA if they are GSM.
However if I key in the code *#*#4636#*#* with daler, (which is the Display information about Phone, Battery and Usage statistics)
I get to a menu that allows setting the ''Preferred Network Type''
is this a system setting used by mannufacture for setting the phone for market, and the phone itself simply doesn't have CDMA?
The specs for this phone
lists nfra: 2G GSM, 3G WCDMA, 4G LTE FDD;
Meaning this phone does indeed use both CDMA and GSM network, is this correct?
If so, how do I sucessfully enable it to utalize CDMA connection?
f not, why does the option for CDMA, LTE appear in the menu, along with many others.
I greatly appricate any responce on this topic

I to would love any information reguarding this. Same phone same specs. Was a little new to how the towers and unlocking system for each set of towers was defined when I unwitting traded my Verizon galaxy note 5 for and unlocked note 5. I was told the phone could be used on either set of towers and that it was factory unlocked and not just gsm unlocked. And that factory unlocked meant that it could be used with any carrier on any tower. Believing this to be miss information I had hoped to root the phone and find a root method for using cdma towers. I have being your own pho e service through straight talk so I had to switch my my sim back to and older phone wich not only is less advanced but also currently seems to be unrootable,because there are no gsm towers where where I live so I have no service at home and I'm out a note 5 and can't root my phone wich is a great dissapiontment for me. But when I open my phone it offers to allow me to choose those towers the same as yours. Someone help me stop this madness.
