[q] hsupa/3g/4g.

I know that 4g is better than HSUPA and 3g.
I recently upgraded my phone to Gingerbreadman.
That upgrade made my phone from HSUPA (HSPA) to 3g connection.
Im not quiet sure if it made my connection slower or its the same.
can anyone tell me more informations about this connection? The 3g word has been bothering me(maybe because ive been so used to looking at the HSPA)

What were your speeds like before you did this "upgrade", and what are they like now?
HSUPA has to do with upload
HSDPA has to do with download
HSPA is 3G
HSPA+ is 3.5G which is what at&t calls "4G"
LTE is true 4G and at&t doesn't offer this as of now.

Are your data speeds slow? Are you in an area where theres HSPA+?

Does the ROM you are using have the H+ symbol or does it just show 3G or H?
I think, regardless of what it shows, as long as your data speeds are not affected, then its normal.

Only 2g or 4g.. never seen a 3g symbol!

Since purchasing my phone almost 2 weeks ago I have never gotten 3g. I have replaced my sim and also upgraded data. I have one day left to return and I'm wondering if you guys too are having this issue. Or perhaps is it a tower/radio issue?

It won't ever show 3g

Yeah i saw the same thing. I think it's has a lot to do with TMO's 4G not actually being a different technology than it's 3G. So in most cases if you have 3G you also have 4G. Are there any areas where you know that TMO's HSPA+ network doesn't have coverage but the normal 3G coverage does? I'd be interested in that. I couldn't test in my area because the 3G coverage is the exact same as the 4G so the indicator would only change if I entered an edge only area.
The G2 only displays an H which can either be 3G or 4G but it's not differentiated on the phone. So I think it's just because of TMO's network not being a separate technology that requires a different radio. So the phone won't go from 4G to 3G to Edge. It goes straight to 2G because 3g and 4G is the same in technology. Only difference is speed and that that's with any network where you have different speeds in different places.

The 4G is a souped up version of their 3G so you won't see 3G ever AFAIK.

Thought i was the only one that noticed

As a t-mob tech rep I can confirm that this is true. The phone will either display 2 or 4. It was even in the brief training we received. No need to return it

Get Mobile Signal Widget if you want to see it go between 3G(UMTS) or H(HSPA+)
It will not show 3G/4G because it would flip between the two too much.

Yesterday I saw it just said "G". Phone was slow as ****. I love this thing.

It's the same on the G2x that I had briefly.

good to know cause im in love with my phone and didnt wanna chance a exchange! its really not enough good about this phone on here but for any of you on the edge its a great phone coming from a hd2 which was also the SH!T !!

Just a little extra info on this. EVERY 3G cell site in T-Mobile's network is HSPA capable so whenever you are on a 3G site your have HSPA access BUT not every site is HSPA+ (4G speeds). With that said, your phone does not know the difference so even if we wanted an icon to show the difference we couldn't have it. There is one more mode and that is UMTS. This only shows when your phone is idle and not doing data (not very often). It does NOT mean your don't have HSPA access on that site, it just means your phone is not currently doing data. So, we could have a 3G icon for when your idle but your phone would be constantly switching from 3G icon to 4G or H (whichever you have) and that would be annoying. Hope this helps.

On the Sensation yes, HD2 running WM though it was about the only way to know

Its a lie. It just says 4G instead of 3G. Never 3G. Its a ploy to make you believe they have 4G everywhere.

I have an unbranded Asian Sensation and it shows 3G once and a while. There is this one area I notice it switches from the H(4G) to 3G. I know TMO changed the H icon with a 4G one so maybe they removed the 3G one show it always shows 4G even if on 3G??

Ive seen it switch to 3g and its like not having internet. Speeds around 50-100 kbps . A friend with mt4g confirmed.

You were on a regular GSM connection, those are old and slow. Not your phones fault, it was basically trying to use data over a rotary phone.

Is your device from tmobile?

[Q] Is there a way to switch between 3G and 4G?

Hey is there a way to switch between using 3G and 4G? I know there is a use only 2G networks option but what about 3G/4G? Thanks

I don't think so...
To my understanding, T-Mobile uses the same network technology for both 3G and 4G (HSPA+) so turning off 4G would also turn off 3G. And if that isn't the case, it still wouldn't make sense to turn it off. It's only affect would be slower internet speeds. I could be wrong here though, lets see what the other posts say.

I think you're right BioRivit. Unlike the switch between 2G and 3G, which involved totally different frequencies and underlying technology, 4G is basically the same technology as 3G, except with a few modifications that allow a faster speed.

It's been a long time since I last heard that... Lol

Ok thanks guys. I guess my real question was supppsed to be how do you tell if you are on tmobile's 3G or "4G". I feel like I've never seen a 3G icon in the status bar, only 4G. Thoughts?

T-Mobile uses the 3g network to transmit 4g. Unlike Verizon or Sprint which have a structural difference between 3g and 4g, T-Mobile is using the 3g network with data compression. This is how they expanded from 3g to 4g instantly, no change in network structure. You won't see 3g again if you have a 4g phone like the G2x. You can only use Edge (2g) or 4g. Hope that helps.

Alright thanks guys

Switching between UMTS and HSPA bug

An almost identical topic already exists in HTC One S section (Radio UMTS/HSPA switching bug (3g/4g)), but I was thinking that maybe there is a different possible fix for Blaze 4G.
I am currently on the AT&T network using Straight Talk SIM. On the status bar it displays 3G with enough bars, but from time to time it stops receiving data in the middle of the transaction. When it happens, the mobile network type is shown as UMTS under "About phone" -> "Status". When it switches back to HSPA, the data resumes. It really messes up my browsing a lot
When I was still on T-Mobile, it did not seem to happen, as the connection was either "4G" or E (mobile network types HSPA+ or EDGE, respectively). I never noticed UMTS in the phone status while using T-Mobile.
One of the reasons I chose Blaze 4G is because it supports both AWS and 1900 bands, so it can work on AT&T and T-Mobile networks. As we know, T-Mobile coverage is not great, so the connection often switched from "4G" to edge. Being on AT&T, the connection firmly stays on 3G, but now I have this annoying bug.
Your input and suggestions would be highly appreciated! By the way, I am using a stock ROM with root.

I have had the same issue with my GS3 as well as my S2 and Sensation, all on T-Mobile. It is something I've noticed. Another thing I noticed, that is shady on T-Mobile's end, is that they show "4G" even if it is on UMTS.

Blaze only has 4g, E, and G, while on T-Mobile that's why it displays 4g while in umts, Umts is 3g and since there is no 3g icon it shows as 4g, hspa+ is "4g"

Is that shady? UMTS Band IV (AWS) provides HSPA+ service. Looks like 1700MHz will be split 50/50 for GSM and H+ coverage, and teh 1900MHz will be split LTE/H+ by next year.
TMO said:
As part of its transition to deploy LTE on its 1700 MHz spectrum, T-Mobile will refarm its PCS spectrum to support both 2G GSM services and HSPA+ services. In a recent FCC filing, T-Mobile said by mid-2013, its expects half of its 1900 MHz spectrum to be devoted to GSM while the other half will run HSPA+ services, and that by then half of its AWS spectrum will support HSPA+ and the other half LTE.

This chart also indicates that the AWS and PCS spectrums are both used for H+ communications. However, it is a tid bit simplified...

Have you tried flashing the other radio? I'm not sure which radio you're using, or if the other one will perform better. However, it does seem like your problem is being caused by the radio.

I am using a stock radio because it supports both 1700 MHz and 1900 MHz bands (Tmo and AT&T) - that is why I bought this phone in the first place. I am not sure there are other radios around for my phone, and even if there are, I am not sure what benefit I would get from flashing a non-stock radio. Very few phones support bands for both GSM providers in the USA; usually, it is either Tmo or AT&T.
On a another note: I got a Tmo SIM card from Straight Talk, and now I do not have this UMTS switching bug. The coverage is a bit worse, but where I have HSPA+, it is still 2-3 times faster than what I got from AT&T HSPA network.

It is not surprising, as T-mobile is rolling out HSPA+ on 1900 MHz band. It will be happening more in the future as more areas will be re-farmed. Since there are only few T-mobile phones that can support 1900 MHz, other users will not see it happen. On the other hand, those few with iPhones on T-mobile network can finally see 3G.
What puzzles me is why it shows 3G instead of "4G" on 1900 MHz band right now? Do they need to upgrade this band to HSPA+ during re-farming?

Yep, it absolutely does on dark knight build 8.
Oh you guys are talking about ...stock..?
Yeah no 3g icon on stock as T-Mo views all 3g as 4g now. There's no 3g icon on ANY 4g T-Mo phone's stock rom (with a T-Mo sim card). It is how they claimed to have the 'largest 4g network' during that ad campaign. Funny how T-Mo no longer claims that (or is no longer allowed to claim that)....
Here where I live I only have 3g. I have verified this using speedtest where I have never had more than 1.7 down/ 400 up. In Minneapolis I know there's 4g service as I have had speeds as high as 11 down / 2 up and average 8 down 1.5 up. All 3 of those statements are confirmed using Dark Knight build 8 as I have a 3g icon here at home and a 4g icon when I am in Minneapolis. The whole drive to Minneapolis showed '4g' on my wife's Sensation 4G. No, I am completely positive there's no 3g icon in the stock rom for any newer T-Mo 4g phone. If there is a 3g icon on any 4g t-mo phone (using T-Mo service), by all means educate me.

There obviously is a 3G icon as in the screenshot i posted. This rarely happens in the specific area I am in a lot (Gym) but my phone is totally stock and always shows 4G everywhere else. Let the screenshot educate you...

[Q] 4G-LTE not work

hello all ..
I have a question.
I have the i727 phone with Cyanogen and Rooted. 4g icon does not appear in the notification bar, the connection works flawlessly, appearing H, H +, 3G but not 4G icon. What does that mean? before when I was working the STOCK ROM 100% sure the 4G, also tell them that in my country there's Connect 4G. but I'm not sure what type of connection that handles the phone. I downloaded this: << radio att-I727-UCMC1-no-csc-no-ril-cwm >> and I've installed, but still the same. I've also changed the APN, choosing the type of APN I select LTE but in doing so cut the signal. (apparently the phone is not supported)
Details:
Before: ATT & T STOCK JB 4.1.2 Rooted
Now: cm-10.1-20130607-NIGHTLY-SuperSU skyrocket + Root file-0.93-Busybox-1.20.2
Is there a solution?

The stock AT&T ROM shows 4G for HSPA/+ but 4GLTE when there's LTE available. Cyanogenmod reports the actual data connection. It shows H/H+ for HSPA/+ and 4G for LTE. That's probably the confusion.

far as I understand, ATT&T has a fault, shows 4G icon when in fact that is not a Connection Connect 4G. I mean, I understand that: 4G is not the same for H+ because H+ is actually 3.5G. it? is this correct?

Correct; AT&T shows 4G even when it is only actually 3.5G. You were probably only getting H+ all along, but AT&T's software misrepresents your connection.

finally! I get it now! ... thank you very much! it is unfortunate that these errors come from the factory that exist only to confuse people.
10 minutes ago, I called my local operator, and said that the 4G or LTE service is not enabled yet in my country. (Just right through usb modem for LTE notebook works here, but not for mobile phones) so which I now understand that 4G phone on the screen showed when it was actually connected to a 3.5 or H + that would be the same thing ...
