Because my touch pro was bought from three Australia it had been modified to only have wcdma and auto in the band selection in the phone settings. Three do not like customers using telstra for roaming, and for most it is probably a good idea to avoid roaming charges on data.
I however like to force my phone to stay on gsm while I am at work because the 3g signal is so weak. All the seeking and switching bands in a low signal environment drains my battery too fast.
After looking around the Raphael thread I saw no mention of this so here is a solution. A while ago user SecureGSM gave us access to a cab he had made for enableing the band tab on other phones. It turns out that his cab also puts the correct values back to allow the selection of gsm only. I attach a copy of it here, it works for me with no bad side effects.
i have installed this : "Nadavi_HTC_Diamond_-_NEW_CommManager.cab"
and simply changed from 3 to GSM under COMM MANAGER..
is your one any better?
Hi,
i am a three user here as well and might have the same problem as you guys,
but as i was wondering, if by forcing the phone to use a GSM network, what if we need to use the data allowance? will we be charged?
as i am on an essential pack where i get 100mb of data usage for 8bucks paid per month, however that will only be deducted off my 100mb allowance when i am in a 3g zone.
Any other good app to stop data connection when not in 3g zone? coz i really dont wanna be charged a hell lot when accidentally using roaming data fees.
Hi guys are we able to select the WCDMA (3G) 900mhz band with any of these apps?
The device has the radio for this but because the 3 network doesnt support this frequency its absent as an option so if i wanted to use it on the Optus or Vodafone 3G 900 i cant as it currently stands.
The silly thing about it is they have the 850 band in the tab but it wont operate on the nextg network as that band is absent from the radio.
Thanks

No, if you are roaming you're subject to those exorbitant roaming data charges, which aren't included in any packs or caps. In terms of data connections, you can just go to the TouchFlo settings tab, select communications and turn off data...
I notice that forcing 2g, calls get that kinda pulsating GSM radio interference noise whereas forcing 3g it does not occur!!!
Anyone else notice this?!!

From what I understand, 4g is 3g, they are HSPA and HSPA+. 2G is GSM. So there are two separate radios in your phone and on the towers.
I just tested this on my phone and can confirm that 3G is a lot less noisier call-quality wise than 2G.
Voice uses 3G as well. TMO throttled back 2G a while back to make 3G faster, so using any phone on 2G mode nowadays is gonna suck more than it would otherwise.

Yep.. 2G / EDGE uses the older GSM data transmission standard, while 3G/4G uses CDMA technology to transmit data.
T-Mobile uses all GSM technology. CDMA is something totally different and is used by Verizon/Sprint in the US.
I'm not a radio engineering expert, but the main difference between 2G and 3G is the protocol. 3G uses more efficient algorithms to compress/decompress the audio (and data) signals. This is the primary reason 3G is faster than 2G to begin with. T-Mobile uses 3G for voice, which means that, in general, calls will LIKELY sound clearly and crisper on 3G than 2G, on average. This is all dependent on network conditions, your 2G signal, your 3G signal, your particular handset, and your own hearing capabilities and preferences. But the idea is like an Mp3 encoding... 3G is 320kbps and 2G is 128kbps... maybe sometimes they sound the same to some people, but technically 3G is "better" under ideal circumstances.
But the 2G throttling I was remembering was actually AT&T, not T-Mobile, though they likely have done something to a similar effect by now.

my question is if 2g and 3/4g have any effect on call quality, how can i receive crystal clear call quality with my data turned off. im not sure 2g, 3g, or 4g have any effect on call quality
None of your voice goes through your data connection. The ONLY way there is any difference is if there is some kind of electromagnetic interference from inside the phone caused by 2G and not by 4G.
As stated above, All voice calls and SMS come through without a data connection at all.

Disabling data does not mean you disconnect from the 3G/4G network. Turn mobile data off and then look under Settings>About Phone>Status, and look at Mobile Network Type. You're phone is still connected to UMTS/HSPA/EDGE/GPRS ... or whatever other type of network it was connected to. And you're not connected to both 2G and 3G simultaneously. Its one or the other and all data and phone transmissions are sent over whichever network you're connected to.

Ah, fair enough. I was under the impression that voice always went through a GSM connection, whether WCDMA was active or not. Has this changed in the last few years?

Don't think it's ever been that way. Phones will switch from one type of mobile network to another depending on user settings and signal strength, but you're only connected to one type of network at any given time. GSM networks utilize 2G technologies to allow for voice and data, but not simultaneously. GSM networks also utilize 3G/4G technologies to allow voice and data simultaneously.
Here's a good source of info on different technologies used by GSM networks:

My bad. Thanks for the link though.
When on 2g my speakers of my surround sound and car audio will make static from the phone... 3g doesn't do this. 2g and 3g are different.
Asus Transformer 3.1 pwnd

So - on an Android phone, do I need to check "Data Enabled" for the better voice quality, or will the 3G/4G for better voice be enabled by default?
No, enabling or disabling your mobile data connection will not affect call quality directly. Your device will connect to the best network available regardless of data being enabled. The only setting you can look at is your preferred network type under mobile network settings.
My phone does something weird. When the data mode, shown beside the battery icon, is shown as 3G, no data transfer can be made until it is changed to 'H'. This gets very annoying.
The problem is that it stays at 3G until I want to do some data transfer, then it changes to 'H' which takes some time.
Anybody gets this as well? Is there anyway to prevent this?

Correct me if I'm wrong. H means HSPA, which is 3.5G, and 3G is 3G in itself, and G is 2G? I thought 2G didn't allow data transmission? So isn't 'G', 3G?
I understand HSPA is supposed to be faster than 3G, but the problem is that 3G doesn't allow any data transmission.

"WCDMA"
H = HSPA = 3.5G

All of them allow data access, or should do anyway.

No, "G" is not "3G". "G" means GPRS (General Packet Radio Service) and is an old standart to transfer data via GSM. It is, in fact, the slowest ond one of the oldest.
There are two networks, "2G" which is "G" or "E" (EDGE which is is a litlle bit faster than "GPRS" - and "3G" (now even "4G" ) which is a high spead network. "H" should mean "HSDPA" or "HSPA"
Oooops, to slow.
In addition: Via 3G you can do data connection and phone calls at the same time, this you can not do in 2G

Your phone will check to see what the best connection available is before downloading. The wait is down to your network provider's service and availability. And possibly your radio. It's not that it wont download on 3G. It will. It's just that 99 times out of 100 if 3G is available, so is HSDPA so it'll go for that one over 3G every time. Unless you are on my network provider. Then you'd get better consistent data transfer over a piece of wet string.
You could go into your phone setting and choose 'WCDMA only' if you generally have good coverage and want to cut the wait out?
Dial *#*#4636#*#*, from the resulting menu select 'Phone Information' then scroll to the bottom and change the drop-down menu to 'WCDMA only'.
Does that help?
Tip:
You can also do this without dialing a code:
Got to settings/wireless & network/Mobile network/Network mode
So you don't have to remember the code if you want to change settings

I tried this. For now it seems that it is stuck at HSPA now! Thanks! Am I right to assume that under WCDMA only mode, I either get HSPA data or no data at all? The phone will not go to 3G or 2G right? (there's no 2.5G here)
Thanks to the others who clarified the 2G,3G,3.5G terms. I understand it more clearly now!

WCDMA only means you will only have HSPA and 3G connections. You will not have, as you wrote, 2G. 2.5G means EDGE which is still a 2G connection but a little bit faster than GPRS, and right, you will not have that.

HSPA includes HSDPA and HSUPA. I really don't know the difference between them.

I'm getting NO data right now. Is LTE down? Any why is it that every time LTE is down, I can't get 3G either
LTE outages started in the Northeast yesterday, but seem to have spread nationwide now. This will cause complete outages on LTE devices due to the switching protocols not working properly
http://www.gottabemobile.com/2011/12/07/verizon-suffering-4g-lte-outage/
I'm experiencing the same thing. Maybe they're preparing for the launch of the two new phones?
Anyhow, my coworker's 3G Droid Pro is working fine...

There is a particular protocol, which currently eludes me, that is required on a mixed LTE/CDMA network to control the switching between the two systems. That protocol is there on every part of the network, not just the LTE segments. If there is a problem with that protocol, this phone isn't going to get any data at all...it doesn't matter if there is CDMA available or not.
Voice and text aren't affected because they don't use the data segment and they don't use LTE, so they don't have to worry with that switching protocol.
FYI For everyone, Verizon just announced about 30 mins ago they have the LTE network back up and running.
I can confirm in NYC i can finally connect back on 4G.
on the device the preferred network type is LTE but most of the time it falls back to HSPA mode and not LTE how do you force the LTE mode only? My location get's 3-4 bars for LTE coverage and all 5 bars for HSPA but LTE is faster
Dial *#*#4636#*#* on the keypad and under phone settings there is LTE only. Your phone won't work for calls possibly after you do this and you won't get data outside of an lte area.

that's why i asked if the issue was solved, there's threads, & posted STILL asking about LTE faulty connections scattered all over the place, so i guess the issue isn't solved in relation to this handset..
i'm in the school of thought, that like a car, or any tool one would use, it's best to grasp a critical understanding of what it's being used ON..
(am i wrong in this assessment?)
from there, once you understand the build of your tool, you compare it what it's being used on, with it's pros & cons; heighten it's pros, lessen it's cons..
wen i went to mexico just two weeks ago, i ordered two telcel prepaid sim cards to use for that 5 day stretch, i noticed i only got version 5 sim cards that didn't do lte that telcel provided, i called back & asked why, & was told that yes, telcel DID provide lte, but not in the area i was visiting, the highest i would get was hspa+, & only in mexico city & within cancun proper would lte be utilied..
knowing this, & knowing i would be off the beaten path on the beach & not in the major city, i opted for the cards sent, settling for the highest hpsa+ speeds..
maybe not all of us, but many of us, purchase our vehicles (& phones) based on critical knowledge of the phone & network in unison, **if we want more utilization from our hansets**

hey, are you on tmobile?
if so, tmobile's roaming is set within it's sim, *unless you manually select a particular nework*
"The device detects and registers on wireless networks inside T-Mobile’s calling area, but roaming networks are usually restricted to T-Mobile SIM cards. You can manually select a network only in areas where T-Mobile does not own GSM spectrum." - ~attachment~
our nexus 5s use single chip, single pathed radios, only one path is used at one time, right?
on the network side, things can be set up pretty differently -
3.3 SUBSCRIBER DATA ASPECTS: USIM/ISIM
Coexistence of LTE with WCDMA/HSPA and GSM Network requires a smooth transition of home location
register HLR towards HSS based on 3GPP specifications. This also helps in providing next generation
Data Layered Architecture that addresses operator’s needs regarding centralization of subscriber data
used for authentication across multiple layers of the same session.
The SIM/USIM is the security token in 2G/3G networks for authenticating a subscriber in the operator’s
HLR. The USIM will continue to provide user authentication function at the access level to the LTE
network.
However, it is necessary to define a mechanism for service level authentication as well, for services such
as the IMS. The ISIM (an application on the UICC) is defined to hold both the user’s access level
credentials and the IMS Private User Identity that is stored in the HSS. The ISIM enables the user to
authenticate to the LTE operator’s IMS network and access its services.
3.4 ROAMING SCENARIOS
There are two roaming scenarios based on home tunneling compared to home tunneling with the
possibility of local breakout as shown in Figure 9. The 2G/3G networks refer to legacy CS or PC based
accesses like GSM/WCDMA in the network
http://www.4gamericas.org/documents/4G_Americas_Coexistence_of_GSM_HSPA_LTE_May%202011x.pdf
to set up domestic roaming on this type of handset ACTUALLY make you roam moreso on other US networks, even though the sim card is provisioned with what network is OK'd?
we're not talking from an older, dual pathed chip paradigm, when that meant exactly *that*..
these newer phones are different beasts..

LTE has an all IP backbone, with no circuit switching mechanism, the network would provide that, & from my understanding from reading up on it, wcdma provides the **IP flattening** for voice on the gsm networks, just as ehrpd does for cdma networks..
what would happen if you switch on domestic roaming in -
APN & data settings
To set the Access Point Name (APN) and turn on data settings, follow these steps:
1.From any Home screen, tap the All appsAll Apps.pngicon.
2.Tap Settings.
3.Under 'WIRELESS & NETWORKS," tap More... to display more options.
4.Tap Mobile networks.
5.Check the Data enabled check box.
6.Check the Data roaming check box to receive data when roaming domestically
7.Uncheck the Data roaming check box when roaming internationally to avoid incurring roaming charges.
8.Tap Access Point Names
9.Choose from the following:•MetroPCS - fast.metropcs.com
•T-Mobile GPRS
•T-Mobile GPRS - fast.t-mobile.com
do you think you'd simply, roam on another provider?
i suspect it would aid your phone in it's LTE to GSM voice handling..
i suspect strongly.. setting it to *LTE* in -
Switch 2G / 4G / LTE
To change the band between 2G, 4G, and LTE, follow these steps:
1.From any Home screen, tap the All appsAll Apps.pngicon.
2.Tap Settings.
3.Under 'WIRELESS & NETWORKS," tap More... to display more options.
4.Tap Mobile networks.
5.Tap Preferred Network Selection.
6.Choose from the following:•LTE
•3G
•2G
..........................
on yet another note,, your handset may be functioning more properly than you could imagine; in your OP
"on the device the preferred network type is LTE but most of the time it falls back to HSPA mode and not LTE how do you force the LTE mode only? My location get's 3-4 bars for LTE coverage and all 5 bars for HSPA but LTE is faster"
tmobile's LTE may simply be having issues for a spell, to be worked out at a later date, & you're falling back on hspa+ asa failsafe..
you may not have to change a darn thing..
In the Palo Alto area LTE doesn't always stay on and the HSPA+ does not actually transfer any data. Sometimes hspa+ is on when weak LTE is available. In situations where I want wreak LTE over strong but useless hspa+ I need to force LTE not just prefer it
