How does the phone switch from hspa+ to Dc-hspa+ - T-Mobile Samsung Galaxy Note II

I was doing some testing on the 4g at my house, I usually average around 4-6Mbps, not bad. Well I did some testing and if I go to *#2363# and switch wcdma to all and quickly did a speed test I would get around 12Mbps, I also check the info on *#0011# and it temporary switches to dc-hspa+ and after a few seconds it goes back to hspa+ and never switches back to dc-hspa+ so im stuck at under 6Mbps. Is there a way to force the connection to Dc-hspa+?

[Q] Should data always be 4G?

Reception is weak in my office at work. On my previous phone, Motorola Defy, I noticed my data would go back and forth between 'H' and '3G'.
With my GS2, data is stuck on 4G. I have watched it for hours now and even though I have no bars it does not change. Am I missing something? Is my device defective?
I appreciate your help with this.

There might not be a 3G (icon) for the phone which is why it stays on 4G rather than drop to 3G.
At least that is the case with my G2X, it is either 4G or 2G but never 3G.
Not sure why, but that's how they made it.
Have you done a speed test to see if you are on 4G or not?
This phone also might have better connectivity to the network.
....
I can at least confirm there is an E for edge Found out today at my apartment in Boston (normally I have 4G with great speeds in Boston, but I guess the bathroom doesn't get good reception)
Thanks for the replies. Yes I ran 4 speed tests this morning in 4G and my max was 1490 Mbps so I think it's working well.

There actually is a 3g icon. It is only displayed for Umts networks. The reason it was done that way is because there is no way to differentiate hspa from hspa+. Two network technologies for 3g were in use anyways and so it was easier to display all hspa and hspa+ networks as 4g and all umts as 3g.

please help Lte

i drove around every corner on my town rockford illinois and lte is strong everywhere accept when i get close to home but as soon as i cross a street it goes to 3g. Is there a app or way to connect to certain towers because i don't this will get fixed by sprint it seems to be this phone format have a lte only option just cdma/lte. i could literally go one block and have full bars lte but soon as i head home it goes from 4g full bars to 3g. a app or something i could flash to just have lte would be great. Because 3g is not usable in rockford just to slow.

Not to be facetious, but once you get to your house, don't you have wifi? Seems like it would be a non-issue to me. :/

I don't know of any option to make it lte only. Also just cause u have full signal doesn't mean you're not on the edges of it. That's your phones signal not lte signal. Same thing happens to me in Baltimore with LTE. I'll have full signal and lose lte connection.

First, understand that LTE service has not been officially launched in Rockford. It is still under development. Full network buildout will probably continue even after the local market is officially launched.
Second, your "bars" display on the GS3 does not reflect the strength of your LTE signal, only the 1x signal used for voice, text, etc.
Third, if you want to understand the Sprint LTE rollout, go to S4GRU.com and read everything.
i asked because on tmobile when i had them you could just turn phone on to hspa only i thought there would be the same for sprint. ALL THE towers in rockford are complete is what sprint told me i should be receiving lte. east side ,westside, south side had lte even the north just the small neighbor hood that i just moved to today doesn't my old house i had lte which is three blocks away.

The only way to force your Sprint GS3 to LTE only is in the hidden debug menus, for which I think you need your MSL. But when you to that, you are turning off all the other radio functions, so you have no voice or text connectivity.
If you had Sprint LTE service a few blocks away and lost it, and it does not come back by toggling the radio (airplane mode, reboot, etc.) then it may be that you were just on the edge of service in the prior location. What kind of data speeds did you get with LTE there?
It could be that inside your new home the signal is just too weak. If that is the only problem location, the best bet is to us WiFi there.

You could try the app "network" to force lte
with your msl can't you adjust the s/n rx and tx settings ? i did this with my evo 4g and worked like a charm since i had 4g outside my house but not inside.

Ah. Makes sense

Can this phone connect to 3G

I've notice that my phone either connects to 4g or edge. So whenever I'm not in the 4g area, I will be stuck with edge. Is it possible to connect to the 3g network to get a better speed?
This phone doesn't have 4G. "4G" = 3G/HSPA. So, there is no problem.
Look all over the forum for further explanation, this has been covered since the phone came out.

Lte Radio band Switch

Hello, when am on Voip or anything for that matter, but really Voip. Am usually on Lte, and then when I get to non-lte coverage it switches to regular 4g hspa. (Common sense)
But it never switches back to Lte while on the call. It wont switch back to Lte until call is over. Even tho am back in Lte coverage.
Is there a work around for this. Would like to be on Lte as much as possible. Thk u

LTE is just for Data, 4g,3g,h ect ect is for voice. Its bcuz voice doesnt need that much usage or amount of speed to call. Theirs time im calling and my phone goes to 2g.. look at it this way the lower the band the more battery you save while in a call.. Google have more info than i can ever give you..that just my 2¢

No 3g on GS4 T-Mobile?

Hello all!
I have an S4. It's fairly new. I like it and all, good phone. Anyway, my one beef is that I have 2 options for data service - 4g and Edge (no LTE here yet.) I wish that I could use 3g when 4g isn't available (edge is too slow) but nothing I've tried works... APN settings, cell network settings.... It's only 2g or 4g. I live in a reframed area (1900 MHz 3g... Cincinnati) which, according to the phone's specs, it should support. Tmobile support said on Twitter that it wouldn't get any 3g, but I like to take what they say with a pinch of salt, especially since a flagship phone not getting 3g is pretty ridiculous.
Any info would be appreciated. Thanks!

I'll give you my best guess. T-mobile doesn't have 4G. They call it 4G, but it's really like 3.5G or HSPA. It will show on your phone as 4G though when you are connected to any "H" network or UMTS bands. When you go into menu> settings> more networks> mobile networks> network mode, you should set it to GSM/WCDMA (auto connect) to force 3.5G or 4G as tmo calls it.
I know this doesn't answer your question per se. Edge or "E" is slow as molasses. Verizon's 3G is almost as slow believe it or not (in my location).
Do you not have WIFI?
Or you can dial *#2263# and you will be in service mode. Choose Lte Gsm. It will force Lte
He doesn't have LTE
GS4

Yeah, I understand that it's "3.5G" but there should be 3G too....not just "3.5G" and 2G...I'm wondering if I can get 3G on this and if not, why I don't. I have Wifi but not when I leave the house
In short the answer is no. Tmo has its network and it is the way it is. Were you with a cdma carrier (sprint / Verizon) before? Sounds like that's what you are looking for
GS4
No, AT&T and Cincinnati Bell before, never used CDMA.
I read that when T-Mobile upgraded their network, they replaced their 3g with 3.5g - leaving only a few small pockets of T-Mobile 3g remaining. Oh well, I guess that's why they're adding LTE - will be nice when they finally get their stuff straight around here!
Thanks for your help

I live in an area with lte but recently traveled to another city. While driving on the interstate I was getting anywhere from E (in middle of nowhere), 3G (near the city) and 4G (once in the city). So I know this phone is capable of 3G in area with no lte/4G

Thanks! Must be just T-Mo's network then. At least I'll have 4g and LTE when they finally get it here.

If I remember correctly when t-mo started with "4g" the majority of the phones had 2 radios, one for 2g and one for 3/4g and it is basically the same way still. So you're never going to see anything in regards to 3g only. but even though your data connection icon may say 4g, u could technically be on 3g at the time.
