{Q} Is This Phone Capable Of..

Is this phone capable of both 3g & 4g speeds, I mean does the "3g" iconactually show up on areas where T-Mobile's HSPA+ is not available? I ask this because I had a GS4G & it was dissapointing not have 3g, it would only jump from 4g to edge, Thanks in advance people!!
ps. I ask because im planning on picking it up if it does, if it doesnt then ill jump over to the Galaxy Nexus.

From what I have noticed, my carrier (Mobilicity) only has HSPA, not HSPA+, so I am always on 3g. I hope that answers your question!
Btw, the speeds I get on 3g are around 3-5Mbps

I've been on everything from GPRS to 4G on this phone, so yes, it does all the various levels of data.

I've seen 3g pop up. But before you think that your sgs4g didn't have 3g,, did you ever run network tracker? The icon can be deceiving mate.

Why does it matter . If your on Tmobile any data you use counts to your cap . I.gues using only 3g will prolong it .

T-Mobile shows you on 4G when you're using 3G. Check your about phone. UMTS = 3G

if you have a 2gb, 5gb, or 10gb plan from T-mobile, once you pass your cap, speeds are reduced to 3G for the rest of your billing cycle.

i'm not sure about being reduced to 3g speed. I reached my cap for the first time last month. my data speed dropped to around 200kbps (edge speeds) versus around 17mbps (4g speed) before getting throttled. i wish it would drop to 3g speeds. that's not so bad. edge speed is really slow compared to 4g.

Unless you have a custom kernel, this phone will only show 4G or E. It is designed that way, so that people don't but a 4G phone and only see 3G if they live in a UMTS area only. It's just for marketing. You can see the 4G icon and get anywhere from 1 mbps to 15 mbps.
And the throttle speed is definitely not 3G speeds. I wish. It is capped at 0.06 mbps

No 3g on sgh-t989?

Can someone let me know why my phone never shows 3g? Either it is showing 'E' or 4G. My nexus used to show 3G.
I am under the assumption that this sgh-t989 can connect to all those networks t-mobile has....
Thanks

It might be because of the fact that everything being advertised now as '4G' is technically '3G.

Thats not true anymore.. the T-Mobile 4G network has been officially recognized as 4G along with WiMax and LTE. Happened a few months ago.
The reason your only seeing either E or 4G is because those are the networks you are near. And many people believe that T-Mo sets the software to show 4G in the 3G area to "lie".. personally depending where i am, I see 3G or 4G we dont have any edge left in my area any longer..
Either way does it really matter? I mean as long as you have a solid connection..

My friend's Nexus S shows 3G or H -depending on which tower it connects to? I don't know but it does show them at different times. we are still living in the same area. So, I am not so sure that they might have "phased out" the 3G. Confusing..

Suppose it doesn't matter but, I'd rather get 4G > 3G > E, and in that order. As you know, 3G is definitely faster than E and not all markets/areas have been upgraded to 4G...

T-Mobiles "4G" is a boosted UMTS (3G) band per say which is HSDPA. As long as the market you live in supports HSPDA you will see a "4G". If not then you will see a "3G". If none of those you will see "E" for EDGE or "G" for GSM. To say that T-Mobile's "4G" is actually 4G is ridiculous.

But T-Mobile's 4G is really fast. Lets not start bad mouthing here.

I get on average 18-20mbps on T-Mobiles "4G" here in South Florida. These speeds are absolutely horrible! Youtube videos are fully cached in seconds and i don't even get the buffering icon so I can sneeze or make sure my car is even being driven in the right direction! Someone should report them to the BBB!

Then call it ridiculous because as of the end of last year the hspa + network was accepted as 4G. As well as wimax and LTE. Since previous non of these where "real " 4G.. 100mbps.

Basically, if you live in an area with mixed coverage where there are 3g bands in addition to hspa plus (a form of 4g), you will see a mixture between 3g and 4g. However, in most areas the 3g bands have been upgraded to support 4g so the 4g > 3g > edge map has the 4g and 3g combined into 4g so you're not losing out on 3g time but rather are gaining 4g time.
Another explanation involves TMobile showing all 3g as 4g regardless of whether it is actually hspa plus or not. This would explain your friend's nexus s coverage changing. Personally, I only see a difference between 3g and 4g on specific roms which would indicate that TMobile does code their roms to label everything above edge as 4g.
Side note: H is the same as 4g as far as we are concerned. H means hspa plus whereas 4g if the more broad category that also includes lte and Wimax. It's like calling my car a ford fusion versus just a Ford. Neither is wrong.
Bottom line: you are not losing out on 3g coverage. At best, you are getting 4g in place of the 3g even when you should be getting 3g. At worst, you are getting both 4g and 3g but your phone is always telling you that you're on 4g

3g/4g question

Hi every body
i seem when my note display 3g the internet dosnt work i need to wait for couple of seconds to display h or h+ and then works. Is that normal? Why i cant use the 3g regular network?

Yes thats normal. Its to preserve bettery the signal will regilary drop down into 3g when idle

I'm on the same boat homie. Can't figure it out. I guess it's just another amazing T-Mobile limitation.

Tmobiles 3g and 4g network are the same the 4g is actually just 3g with better antenna technology and I think a power boost. The 3g network is called hspa and 4g is hspa+. That is why att had 3g 3.5g and 4g att considered the hspa+ 3.5g because they launched their lte network as 4g. So technically when tmo launches lte it will be tmos 5g. They changed the definition of the whole thing a while ago. G stands for generation. So that is why tmobile is allowed to call it 4g because it is their 4 generation of high speed internet. There is no actually standard. like edge being 2g hspa being 3g lte 4g the way it should be.
For the roms that use the h, h+, 3g format usually 3g actually EDGE or 2g. H is 3g and h+ is 4g So the net is probally not broken it is just ridiculously slow. I hope I explained that right. That is what it seems like to me from GOOGLEING it.

Hey thanks for that info. I tested out all networks again...
4G = Fast Data.
3G = No Data AT ALL.
Edge = Slow Data.
If T-Mobile's 4G and 3G networks are the same thing, why don't I get data when the phone says it's connected to a 3G tower? I had 3G service with my previous phone and it had decent data speed. I could stream music and browse the web easily. Now... 3G just doesn't work at all.

4G, LTE, WIMAX and GS3

Can someone tell me the difference between, 4G, LTE, WIMAX and GS3? What does the GS3 have and on my previous HTC phones, there was a toggle/setting to turn off the 4g Radio. I don't see anything but "mobile data". Is that 3G, 4G or both?
Bob

4g and wimax are the same thing which is 3g revision b or c depending on carrier. Standard 3g is called 3g revision a. But the FCC gave them permission to call it 4g since it data speeds can go up to 9mbits per second. LTE is the true 4g. LTE stands for long term evolution. Its data speeds can go up to 40mbits per second. So if you see carriers saying 4g without LTE after 4g they are technically lying to you. Gs3 I'm assuming your talking to Samsung galaxy s3, it just has the ability to use all of them since its multi carrier.
Mobile data is both. 3g and 4g and 4g LTE are mobile data. So if you turn that off all data will be turned off. Some phones don't give you the toggle to turn off 4g but I think there are custom roms that have that feature.
Sent from my Incredible 2 using xda app-developers app

Mobile data is any internet connection, however it depends on the rom as to whether hitting a widget that says that will toggle 4G AND 3G as some roms (like stock HTC ones) provide separate toggles
Wimax is a type of 4G and so is LTE, if you want more specifics I would start with Google

The s3 has 3g and 4g lte radios only, no wimax and if your not in a lte area you will only get 3g speeds which are slow. I live in Illinois and there's 4g lte in most areas.

Please tell me this was just poorly worded and not your entire take on the 4G/Wimax/LTE situation. This post made my head spin, and now I need to write a long post explaining everything that's wrong.
First of all, there is no "3G Revision B" or "3G Revision C", let alone "3G Revision A". That's ridiculous. 3G is a marketing term. There are several 3G technologies, including EVDO (which Sprint and Verizon both use for their 3G technology) and HSPA (which AT&T and T-Mobile use). There is an EVDO Revision B and C, but Sprint uses Revision A. No one uses EVDO Revision B or C. Either way, EVDO Revisions B and C are entirely unrelated to either Wimax or LTE.
The FCC didn't give anyone permission to use the term 4G for anything. They don't care what you call the technology as long as it complies with FCC regulations. The rest is just marketing speak, and the FCC wants nothing to do with it.
Wimax and LTE are both types of 4G. There is no "true" 4G in this case. 4G is just a marketing term for what they consider the 4th generation of mobile data protocols. 4G and Wimax may be used interchangeably, and so may 4G and LTE. If you're being specific about one, be specific about the other. Saying things like "4G or 4G LTE" sounds stupid to me when the person means "Wimax or LTE". It's like saying "Do you want cookies or chocolate chip cookies?" Either way, you're getting cookies - one's just more specific than the other.
Other carriers do not need to put LTE after 4G in their marketing. No one but you decided that LTE was "true" 4G over Wimax. Both are 4G (barely), so it doesn't really matter which 4G technology they use. It's still 4G. No one is lying just because they don't specify which type of 4G they use, which is a moot point anyway, since Sprint is the only carrier that used Wimax for their 4G technology. It can just be assumed that 4G == LTE in other companies' marketing. Likewise, it's not lying if Sprint says "4G" instead of "4G LTE" either. It's just marketing.
As for speeds, neither protocol is limited in the way you mention. Wimax as a protocol is in no way limited to 9Mbps speeds. First, Sprint's Wimax could go much faster than 9Mbps easily. Second, the speeds are not limited by the protocol. They are limited by the implementation of the protocol. It's possible to hit 40 or 50 Mbps with Wimax if you have enough spectrum and backhaul available. Likewise, LTE is not limited to 40Mbps either. If Sprint had the spectrum and the customer base, they could roll out LTE that goes to 150Mbps or more. It just depends on how they scale it.
And finally, the GS3 does not have the ability to use "all of them". The Sprint GS3 is not compatible with Wimax at all - just 1xRTT, 1x-Advanced, EVDO Revision A, and LTE. And that has nothing to do with it being multiple-carrier anyway. If that were the case, we could use AT&T or T-Mobile's HSPA+42, and they could use EVDO Revision A, but neither of those things is possible IRL. Samsung made the Sprint GS3 compatible with the technologies Sprint was using, and likewise for all the other carriers' models. There is no need to look any further into it than that.

H+ or 3G what is the difference?

every time i browse the net on my Note 2 I'm getting "H+" on the status bar in my area while at the same time whenever i call someone i get 3G at the same place, so what is the difference between them? which is better? sorry if it is a noob quastion

H+ is for HSDPA+, which delivers much higher speeds than normal 3G. Technically it is an upgraded 3G network. so if you have H+ then your network is faster than if you get only 3G. and H+ is used only for data download. so you will not see it in normal voice calls.
Based on your network, Note II can handle H+ speeds up to 42Mbps. 3G is only 384kbps.

Capable of 42Mbps!? I can't imagine anyone ever gets anywhere near that. I only get 35Mbps on my home computer with cable internet.
With H+ in my area, I generally get somewhere around 3Mbps maybe a little higher.
What is the max speed of LTE supposed to be?
Now that I know my phone is capable of 42Mbps (which is faster then my home connection), I really have no problem with not having an LTE phone. Especially since the max speed is probably as probable as seeing a unicorn.

Not to put a damper on it, but H+ doesnt mean DCHSPA as my N7100 shows that symbol and its not DCHSPA capable.

That's because H+ means HSPA+. Unless that's what DCHSPA is, but I've never heard it called that before. Even then, are you sure about that? HSPA+ is listed in the specs for this phone.

HSDPA, 42 Mbps; HSUPA, 5.76 Mbps; LTE, Cat3, 50 Mbps UL, 100 Mbps DL
H+ is faster than 3g without a doubt
DCHSDPA is known as dual channel ie three uk are dishing it out but us n7100 owners nothing to get excited over its not supported..
Mainly only lte models have dchsdpa only a couple of non lte devices have it

Well, that sort of clears it up. (Although I don't fully get it, I sorta do) Not like it really matters though. No one is going to get anywhere close to what those technologies are capable of anyways. If they ever do, we will probably all be on our next device anyways(probably more like a few devices down the road).
