[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.

That's what it did for the HD2 & it let me know when I was actually pulling down data, just look for 3G or the H

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?

How to disable HSDPA on Nexus S

Any tips on disabling HSDPA on the stock Rom? I know the Galaxy S and S2 have a simple dial code menu to do this, however an easy way on the Nexus S still eludes me.
Thanks in advance.

Why not just tick the "Use 2G only" in wireless settings?

There appears to be an issue with Samsung GS2 and Nexus S and my ISP, see: http://community.vodafone.com.au/t5...Galaxy-S-II-Internet-Problems/m-p/24265#M1553
I suspect the issue has to do with this "lock/test/switch" to hsdpa, and I would like to test that theory out

Nexus S doesn't have HSPA+...

You are right, disregard that +

I'm also interested in finding a way to disable HSPA on my Nexus S. For anyone who's interested in knowing why, it's because of a long-standing, infuriating and utterly ridiculous Android bug that supposedly leads to the watchdog service to think that the PDP context has gone down, causing it to ask for a new one. Naturally, the 3G network doesn't allow it, and all hell breaks loose.
How they manage to miss crap like this, I'll never know. The Android kernel source code in question even has a comment in it identifying it as a kludge.

I think that's only partially true. NS caps at 7.2mb's while a myTouch 4G caps at 11.something. Anyways, they both still use the same HSPA+ network. My friends NS gets about 4-5mb's down, which is about the same that I get on my myTouch 4G in Los Angeles.
So I think the NS still gets HSPA+, it's just capped lower than TMO's 4G phones that's all.

the ns gets hspa not hspa+. it uses the hspa+ network, but is still hspa.

No offence, but how is any of this related to the issue at hand?

I think you have to disable the data connection altogether or go back to 2G

Unfortunately that's not an option. I still need a data connection, but my carrier has extremely poor 2G coverage in my area. I've read that it is possible to modify the build.prop file to disable HSPA while leaving 3G active, but as I understand it this requires your phone to be rooted. Can anyone clarify on this?

hspa is 3G

Have we not already had this debate? 3G is WCDMA, which is not HSPA. HSPA is 3.5G.

4g speeds

hi im a noob here,is there a way to speed up my 4g

Roms and Kernels........check them out. they help with speed, features, and just overall use of the phone in my OP.

No. The network is almost always the limiting factor here in terms of data speeds.
Right now the stock Froyo ROMs (which use the stock RIL and APN) provide the fastest data speeds.
Gingerbread ROMs provide a lot of new features but at the penalty of data speeds in some areas because the Rogers RIL doesn't always play nice with AT&T's network. (I see no difference, but I'm in a semirural area that has always had slow data speeds, we only got 3G 2-3 years ago.)

You can switch to a carrier with an actual 4G network.

No you can't. Not a single carrier meets the original 4G definition.
Verizon LTE is the closest (by a long shot), but it's still not 4G, it's 3.9G.

[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
