I've got a G1 right now and was wondering what the deal is with tmobile US and the lack of hero? Is there any reason that tmobile denied it and what exactly are the limitations if I tried 2 use a hero on tmobile US?
The Hero currently sold in the EU supports 3G in the 900MHz and 2100MHz bands. T-mobile USA licensed spectrum in the 1700MHz and 2100MHz bands (in different geographic regions). Of course, 2G (voice and EDGE data) works everywhere, but Tmo is probably waiting for a version with the correct US frequencies.
o gotcha so basically almost everything would work, there would just be a 3g sacrifice...ugh not so good, but guess thats what is about to go down for the US, thanx for clearing that up
Would it work for att 3g? Or is it diff frequencies also?

I recently switched to Mobilicity from Rogers...but the irony is that I can't use my lovely X10 on Mobilicity. Mine is X10a, and I recently flashed it to X10i (although I didn't know it will switch to X10i, but it did) using forum.xda-developers.com/showthread.php?t=825201 tutorial.
Ok, the big question is that can I somehow manage my X10 to work on the frequency Mobilicity is providing. Following are the lines from wikipedia.
"Mobilicity uses the UMTS IV frequency band, also known as AWS, to provide UMTS (with HSPA) service.[11] Using this band, user equipment transmits at 1710–1755 MHz, and receives at 2110–2155 MHz. This is the same frequency as Wind Mobile and Videotron in Canada and T-Mobile USA. Like WIND, they do not have a GSM network."
"The Xperia X10i uses GSM/GPRS/EDGE 850/900/1800/1900 and UMTS/HSPA 900/1700/2100. The Xperia X10a uses GSM/GPRS/EDGE 850/900/1800/1900 and UMTS/HSPA 800/850/1900/2100."
Please be easy on me as I am a newbie

the carrier is not going to change the frequency for you.. As it looks Videotron and Mobli will survive Wind took a hard hit just today. The CRTC and Industry Canada are getting pressure to reopen the ownership debate. If that falls though Rogers will add data to chat-r and seal the fate of Wind. Then you can simply switch over and be fine.

ok, I will wait for a month or so. I guess North American handsets always had problems. I remember I took couple of handsets to South Asia 5 years ago and they werent working there, but their handsets worked in North America.
Btw, my current plan is 35+tax and it includes.
Unlimited Incoming & Outgoing
Unlimited Text (Global and domestic included)
Unlimited Long Distance for North America
Unlimited Data
Caller ID, Call waiting, Voicemail, Call Forward, 3 way calling
I doubt Rogers or its subsidaries can offer such a plan.
Btw, I am a webdeveloper who wants to get into mobile development scence as well. Any guidance will be appreciated as I am a complete newbie when it comes to mobile development.
It is funny to tell but my x10a is not working the right way
The 3G working bands are as the service menu says:
umts_bc1, umts_bc4, umts_bc8
instead of
umts_bc1, umts_bc2, umts_bc5, umts_bc6
So I can't use the 3G anymore that's because in my country none operator uses the bands that my phone has, It seems my x10a phone uses x10i bands now.
Hi, I have the white s2 i9100unlock version and when I put in my
Tmobile Sim card it says that I am running on E network instead of 4g. Is there anything I can do to change this? I contact Tmobile and they say it's the phone not their line. Please help me out because running on the E network is very slow

The international i9100 does not support 4G. Only option would be to get a 4G enabled one.
its because the international galaxy s2 doesn't have the same 3g bands as T-Mobile (assuming you are T-Mobile USA). They run off of 1700/2100 while the phone itself supports 850/900/1900/2100. While only the 2100 band matches, if you don't get 2100 coverage in your area, you will default to 2g.

So you started another thread on this, where I also answered your question. This phone will never get HSPA+ speeds on T-Mobile USA - or what they call "4G". It lacks one of the necessary frequencies for it. It will only get Edge speeds. From what I remember on how T-Mobile USA's network functions, 3G and "4G" need both 1700 and 2100 mhz to function, as it uses one frequency for download and the other for upload.
EDIT: Here's the wikipedia article on AWS, which is the band T-Mobile uses for 3G/4G. In brief, AWS uses 1700 Mhz for uplink, and 2100 Mhz for downlink. So since it only gets half of the band, it won't do "4G".

Unfortunately, the bolded/underlined part is simply not true. T-Mobile USA needs your phone to be able to get both 1700 mhz and 2100 mhz UMTS frequencies to do 3G/4G. If your phone doesn't have one of the frequencies, it won't do 3G/4G at all, and fall to Edge (2.5G).
What if I overall another ROM? Will it help?

No. The phone simply doesn't have the hardware to receive the frequency. Nothing you can do to fix this.

You need Galaxy2 HD LTE to access 4G. That particular model is not available outside Korea at the moment. If you want 4G, try Samsung Galaxy Note or LG Optimus LTE - also known as Nitro HD, or HTC phones.

That indeed is weird and inconvenient, but I guess telco's can setup their system however they like... It may have lot to do with number of people using mobile services. In OZ we have 22 million potential mobile users using 4 major telco companies, whereas in USA, they would get most of OZ population just in New York city, let alone rest of the country.
Ah systemcrasher I think they might be load balancing the hspa+ mimo across the two freqs. Telstra nextg doesn't need to coz there's allot less people here.
If that's the case still should be allowed to fall back to a non mimo mode.
Let this be a lesson to the OP, always research all carrier pre requisites before buying, also consider other carriers encased you'd like to stay open to other options.

So the answer is the link to the wikipedia article in my quote above. It's not T-Mobile USA's doing per se - they just purchased the AWS-1 (also known as UMTS band IV) band of the spectrum. That's just the way this band is set up. Wind and Rogers in Canada also use this band.
Hi everybody,
The previous HOX was not supporting the 3G data on t-mobile due to lack of HSDPA 1700 as far as I realized. It seems that the same problem remains with the new HOX+ too since it cannot support HSDPA 1700.
Does anybody know something about it?
Thanks in advance

I think when T-mobile refarms the area you live in this might give you 3g for unlocked ATT phones and international versions also.

I hope it goes as you said in our region. I've seen an AT&T version of HOX+ which will support more Network frequencies as well as LTE. Would it really matter in my case? Should I go with the unlocked AT&T version or an international version?
I'm waiting until the dust settles on the refarming and on the next batch of nexus phones. Then the selections and used prices should really improve.

The short answer is no. First you divide the phones into two groups; GSM and CDMA which are incompatible networks, apart from limited overlap on the data side. Note that Sprint in particular, locks down their CDMA phones pretty tight so that it is very difficult to use them on other networks, particularly competing domestic CDMA carriers.
GSM phones, at least the higher end models like the S5 are multi band and will work on pretty much all GSM networks. However each model is optimized for a given carrier's frequencies. So your phone may roam or (if unlocked) accept a SIM from another network, it probably won't work on all of the frequencies of the other network. The effect of that may not be much in a dense urban area, perhaps a little more network congestion or slower data speeds. But in fringe areas served by only one frequency, it could mean no coverage for the foreign handset.
The TMobile model is one of the best, generally speaking, in that it is capable of operating on more frequency bands than most other models. However what is best is subjective depending on where you want to use it and what model you have in hand. The Samsung support site lists the frequency bands that each variant will work on and you can see that they vary between carriers.
Interestingly it appears that the GSM S5's are manufactured with the hardware capability to operate on all GSM and LTE bands. But the different models only enable the frequencies used on the native carrier. Which is to say marketing (or by a real stretch, perhaps cost saving) initiatives are locking us out of better roaming capabilities.

Well again what you say is only correct for certain countries in asia. Not to single you out but there is a lot of misinformation, usually assumptions on this subject and it's productive to clarify the facts.
There were both LTE and non-LTE versions of the Exynos (4 core) S3. The GT-I9300[N/T], SHV-E210K/L/S and SGH-N035 had 4 cores and LTE and the GT-I9300[N] had 4 cores without LTE support. Not to mention that various asian counties like Japan and Australia use the dual core Qualcomm S3 with LTE. So it's not as clearly delineated as you believe.
You also suggested that it costs more to add additional frequency band support to a S5 variant. But this isn't so because the S5 uses WRL-1625 transceiver chipset which has unified support for all GSM and LTE bands. So it costs nothing extra in hardware to add additional bands.
One could argue that omitting secondary parts such as an antenna in a variant intended for a region that doesn't use LTE at all (if such exists) could make unified support moot. But the reality is that increased manufacturing and logistical costs of changing the hardware provisioning on variant handsets is usually prohibitive. It's generally believed that band limitations between variants reside in firmware with the purpose of detering grey market sales and carrier churn.

No, most of the non-LTE asian carriers are using HSPA+ networks which are considerably faster than Edge. The faster HSPA+ implentations are characterized as 42 Mbps networks, which is as fast as some LTE footprints. Advanced LTE rollouts however can double those speeds.
.
I had several people ask me about real world LTE speeds. All I can say is that speeds are highly dependent on carrier networks and will vary considerably between carriers and quite a bit by location as well. One LTE network might see speeds < 5 Mbps while another may be twenty times that fast.
I am seeing 60 Mbps typical speeds with my LTE and ~ 90 Mbps with a strong signal in larger cities. Carrier aggregation which is just rolling out now (and supported by the S5) should see some networks achieving 125+ Mbps speeds.
