How to use H only as internet?

When I connect to internet depending on the location sometimes I get the G icon sometimes the H icon.
Is it possible to set it only to connect on H (even if reception is bad, 1 bar only, rather than G with 3-4 bars reception)
Is there an App for it? than can let you choose what you wanna connect to?
I know in my nokia n95 i could go to networking and choose what i wanted but i cant seem to find that on the galaxy s.
any help would be great
thanks

LOL...
G - GPRS
H - HSDPA+ (faster than 3G)
You can't change it, It depends on your signal strength and location.

constant HSDPA+ would also kill your battery too..i would image ye?

Only as much as what constant 3G uses.

im sure its possible because here is how to do it on the Omnia HD, its just a hidden menu setting
http://forums.samsungi8910omnia.com...ncrease-web-browsing-speed-when-using-3g.html
we have the same menu on the Galaxy S, so if someone can just figure out how to get to this part then you can do it

That is to increase the speed of the 3G. You can only see results if your using 3G,not sure it will increase the speed of the HSDPA. Also this wont allow you to get more of the signal or allow you to use just 3g or hsdpa for internet, again its down to network signal and location.

You could do *#*#4636#*#* in the phone app and change CDMA/GSM Auto to WCDMA or WCDMA preferred for 3G only, but you will have no service if you leave 3G coverage since it will not revert to standard GSM.

That method didn't work for me when I tried it; each time I re-entered the menu, the settings had reverted to whatever was chosen in Menu -> Settings -> Wireless & Network -> Mobile Networks... either GSM Only or GSM/CDMA auto (PRL) depending on whether the 2G only box was checked.
To get 3G only, enter ServiceMode:
*#*#197328640#*#* -> Debug Screen -> Phone Control -> Network Control -> Band Selection
Choose WCDMA BAND for 3G only.

Yes thank you for this informaion. I was able to get to the service mode but was not able to change the band selection.
I receive the error: RAT Selection Option is Restricted !

theres probably a way to shortcut the screen with anycut but ive given up trying
I cab only get edge at work but it does actualy give me about 100 kbs

Useful General Information Regarding 2G and 3G for either CDMA or GSM modes

Useful General Information Regarding 2G and 3G for either CDMA or GSM modes
For CDMA Networks there are Only three Modes Controlling CMDA 2G or 3G:
CDMA only CDMA phone force Only 2G Mobile data. if 2G signal is too low you get no Signal.
EvDo only CDMA phone force Only 3G Mobile data. if 3G signal is too low you get no Signal
CDMA auto (PRL) CDMA phone can use both 2G and 3G Mobile data . if signal strength is low then 2G is favored more.
Please see Automatic Mode ( GSM/CDMA auto (PRL)
TWO GSM Modes that include the word "CDMA ",But They Do Not Relate to CDMA Networks :
WCDMA preferred GSM phone can use both 2G and 3G Mobile Data . if signal strength is low 3G is Preferred .
WCDMA only GSM phone forces only 3G Mobile Data . if 3G signal is too low you get no Signal .
Other GSM Modes :
GSM only GSM phone forces only 2G Mobile Data . if 2G signal is too low you get no Signal .
GSM auto (PRL) GSM phone can use both 2G and 3G data Mobile Data . if signal strength is low 2G is Preferred
Automatic Mode :
GSM/CDMA auto (PRL) - phones equipped with GSM and CDMA .( Not Sure ) phone attempt to stay connected to the Mobile Data type that works the best ( through choosing the CDMA network directly or GSM Roaming networks , not sure ) ??????.
Auto PRL ( Preferred Roaming List ) :
this list should be updated frequently , help connect to 3G ? . to get update ( through *228 or through Dialing ##778 , Then Select Prl then Update . i don't have much Knowledge about the following , But some who change Carrier would download PRL suitable for the New Carrier and replace the existing . through using certain Software ( Powerful Software that Can damage Your phone if you Don't know what you are doing ) , and is that required or Not . for myself i would not do it unless it is a Must.
Hope help testing and adjusting setting for 2g,3G , i myself was confused about some of those setting Especially WCDMA Preferred
You can reach All the above Options through Phone Information menu ( called also testing menu ) by dialing *#*#4636#*#*​I appreciate if you hit thanks Button , if you found this Post useful

While working for Verizon I know that *228 option 2 is the one you select to update just the PRL. When updating the PRL it just ensures your phone has been updated on the network with latest additions to towers and such. Possibly can improve your signal strength in areas where improvements or new towers have been added. This also can help when you travel in extended network where Verizon has a roaming agreement. It is recommended to do so atleast 1 time every 3 months.
Choosing option 1 from the menu is for when you are changing devices(esn's) on your number. This will program the proper MDN and MIN as well as SID into the phone so it can work on your number and the Verizon network. Sometimes doing option 1 can resolve issues with your device as well, but in rare cases.

so there is no way can force the htinc2 to work with h or 3g

yes you can force 3G as follows ( All mentioned in my above Post ) :
for CDMA ( if you want to use CDMA network Only )
EvDo only CDMA phone force Only 3G Mobile data. if 3G signal is too low you get no Signal
For GSM ( if you want to use GSM networks only )
WCDMA only GSM phone forces only 3G Mobile Data . if 3G signal is too low you get no Signal .
if you don't want to force 3G only , But make 3G Preferred when Both 2G and 3G are available :
for CDMA ( if you want to use CDMA network Only ) :
CDMA auto (PRL) CDMA phone can use both 2G and 3G Mobile data . if signal strength is low then 2G is favored more.
For GSM ( if you want to use GSM networks only ) :
WCDMA preferred GSM phone can use both 2G and 3G Mobile Data . if signal strength is low 3G is Preferred .
For Both ( Auto ) :
GSM/CDMA auto (PRL) - phone attempt to stay connected to the Mobile Data type that works the best
You can reach All the above Options through Phone Information menu ( called also testing menu ) by dialing *#*#4636#*#*
i guess it works like this but not sure ,
if you choose EvDo onlythe phone will force the connection to Verizon Wireless 3G only , it will not try to use the sim Card to use the roaming GSM networks !!!
if you moved to another GSM carrier ,then you have only GSM ( No CDMA ) , then if you used WCDMA only the phone will only connect to the 3G provided by this Carrier

Reception issues finally solved! [TELUS maybe BELL]

So I've been struggling with shoddy reception for a long while. The desire isn't exactly known for its reception, but recently I changed buildings and it's been unbearable.
Symptoms:
- If coverage is poor I'd go in and out of service frequently
- Sometimes, even with bars, texts won't send and calls won't go thru
- Sometimes, stuck in emergency calls only until a reboot
- If coverage was is, no issues
Cool. So the flaky behaviour all had to do with preferred network type. Turns out TELUS doesn't have a 2G network to fall onto if the 3G signal is crappy (remember they used CDMA tech for their 2G; it's not compatible). But most roms in here always assume you do. The phone would go full retard (beg your pardons) trying to find the 2G network that doesn't exist. In addition, many power saving "tweaks" change the preferred network type from WCDMA perferred to GSM auto PRL ... both assume you have a 2G network. The latter specifically has brutal performance on TELUS network.
Fix :
Get a build.prop editor from the market
Change ro.telephony.default_network = 2
2 is WCDMA (3G) only
Reboot
or
Dialpad > *#*#4636#*#* > Phone information > Set preferred network type > WCDMA only
But I don't believe this method will stick after a reboot
Cheers guys, I hope this helps you like it did me
ro.telephony.default_network=
0 = WCDMA Perfered
1 = GSM Only
2 = WCDMA Only
3 = GSM/WCDMA (auto mode, according to PRL)
4 = CDMA / EVDO. Perfered

How to set network mode to 4G only?

Please help.. Is there a way to set network mode to 4G only or LTE only?... In settings, I only have the Autoconnect, 2G only and 3G only options.. Thanks..

Is your SIM card already 4G supported? What's your carrier?

The 4G auto connect is available? Apps might be able to access 4636 without root. In there, if there's an option, select phone information, then lock the RAT to 4G only. Alternatively, if *#2263# or *#2683662# is available, in *#0011# select the other SIM if there is any, then in those other codes, band selection, GSM ALL (for the unused SIM), change SIM again with *#0011#, band selection, LTE ALL(for the used SIM). What's expected: If the SIM is not a USIM, the RAT will stay on 3G(UMTS/WCDMA). If the USIM is not authorized, no signal. With soft PLMN locking (manual operator search) the signal level is shown but it's unusable. If the signal is still not available, maybe the phone does not support that band/frequency or no LTE coverage? If rooted it's possible to add LTE only in those settings in feature.xml, if that file is not available others.xml is used. Or launch 4636, or RIL service mode with am broadcast.

Use this app (no root needed). Set to LTE ONLY. Works fine.

This is worth a try. It's 4636.

ADD THIS IN system\csc\other.xml
<CscFeature_Setting_CustNetworkSelMenu4>LTEONLY</CscFeature_Setting_CustNetworkSelMenu4>

its very easy. you just need to install this app https://play.google.com/store/apps/details?id=com.teknokia.mtkengineerapp&hl=en and choose LTE Switcher menu. for detail info please go to https://www.teknokia.com/2017/08/how-to-lock-4g-only-or-lte-only-on.html

SM-T807P with not support to WCDMA

I have a SPRINT SM-T807P pre-owned tablet working 100% OK.
The device IMEI is clean and I'm outside the US.
I could find the 2G/3G/4G technology and bands supported prior to buy the device through eBay.
Then, running stock ROM MM 6.0.1 updated > root > unlock and debranding to clean SPRINT apps and restrictions with others carriers SIMs.
I have 3 SIMs from my 3 local carriers and I know I can't use LTE since the carriers LTE bands are not compatible with the device (Band 2 and Band 4 required by the carriers)
www_gsmarena_com/samsung_galaxy_tab_s_10_5_lte-6235.php
No problem with that, I can use 3G/2G mobile data for my internet surfing and email check tasks.
My problem is that my device is not supporting WCDMA!
When I'm in IOTHiddenMenu > ##DATA# Menu > HDR/1X Selection, I have only these options:
1) Hybrid
2) CDMA Only
3) EVDO Only
4) EHRDP 1x
5) Global
6) LTE + CDMA + EVDO
7) LTE only
As you can see there is nothing related to WCDMA!
Using "Global" is not the trick.
In GCF SETTING when going to
[2]UE Setting & Info
[1]Setting
[1]Protocol
[2]NAS
[1]Network Control
[4]BAND SELECTION
I can see "WCDMA Band Preference" > "WCDMA ALL" option but this setting is not saved.
Only are saved the options related to LTE, CDMA or LTE+CDMA.
Same behavior when going to RADIO SETTINGS > Set preferred network type. GSM/WCDMA options present but are not being saved nor accepted. I can save only options with LTE or CDMA (or both) involved.
RTN RESET and NV REBUILD done without getting WCDMA enabled after the tasks.
Now I'm in the way of discover why all the people with SPRINT SM-T807P can enjoy WCDMA services after unlocking the device and I can't do it as expected.
I'm thinking that is a restriction on the stock ROM.
I have a MSM8974 board with a Snapdragon 800 processor.
Build ID MMB29M.T807PVPU1CPI1
Any help/advice to enable WCDMA on the device will be really appreciated.

Additionally, when I'm in RADIO SETTINGS for some reason I can't select some options.
With a (*) mark are my "selectable" options. The other ones can't be assigned...
WCDMA preferred
GSM only
WCDMA only
GSM auto (PRL)
(*) CDMA auto (PRL)
(*) CDMA only
EvDo only
(*) GSM/CDMA auto (PRL)
(*) LTE/CDMA auto (PRL)
(*) LTE/GSM auto (PRL)
(*) LTE/GSM/CDMA auto (PRL)
(*) LET only
(*) Unknown
All the "selectable" options were tested (selected and restart) with no success...

Maybe I need to enable LTE/HSDPA/GSM required bands through CDMA Tools or it seems to be a bad idea?

Adding additional LTE Bands was not possible with CDMA tools.
The new selection is not being saved.
I'm in the way of flashing the stock SM-T807T (T-Mobile) on my SM-T807P (Sprint) to check the behaviors.
Any advice will be really appreciated...

I could see at the Qualcomm website that the Snapdragon 800 processor supports WCDMA and full LTE bands frecuencies:
Supported Cellular Technologies
LTE FDD
LTE TDD
LTE Broadcast
WCDMA (DC-HSDPA, DC-HSUPA)
TD-SCDMA
CDMA 1x
EV-DO
GSM/EDGE
https://www.qualcomm.com/products/snapdragon/processors/800
I'm in the way (too) of searching for the correct MODEM flash file to get LTE, WCDA and GM/EDGE fully unlocked and working...

It was not possible to flash SM-T807T (T-Mobile) stock ROM from SAMMobile on SM-T807P (Sprint)
There is a Odin error.
I will try by editing NV to get the bands working...

Well, after working with CDMA Tools, NV Manager and editing the build.prop file, now I can see my required LTE, WCDMA and GSM additional bands! No more "Searching network connection" on the top left corner.
But the signal icon on the top right corner is always empty (no signal at all).
I have checked, deleted and reconfigured the APN, with no success.
And still I can't set "GSM auto (PRL)" on the Service Mode as "Preferred Network Type" so I believe I'm missing something else.
I'm really exhausted, I need help to be able to get my Samsung Galaxy Tab S working OK on my local GSM networks.
I will open a new thread offering to pay/donate for the service to have my device working on GSM ...
