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

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.

SCH-530U US Cellular on Tmobile 4G LTE (HELP)

While messing with the setting in the hidden Menu.
I unlock the T-Mobile LTE Network on My US Cellular GS3
Internet: T-Mobile US LTE
Band: LTE:14
Data Speeds 20mbps down 3.6 mbps up
Mms: Works Flawless
Now My Problem. i cant make a phone call or receive a phone call
My Setting
Hidden Menu: *#22745927
enable hidden menu
*#197328640#
[1] UMTS > DEBUG SCREEN > PHONE CONTROL > NETWORK CONTROL > BAND SELECTION to set GSM Band preference
[2] CDMA > COMMON > NEXT PAGE > NEXT PAGE > PREF MODE SET to select GSM/WCDMA ONLY
SIM>TEST CSIM
WAIT 90 SECONDS THE REBOOT
VOILA! TMOBILE LTE.
Now i have succesfully unlock The Verison GS3 to Tmobile on Edge is there a way to port that radio. to get cell connectivity.
or if anyone want to try to tweak these settings to get more than just LTE connection. or get Voice over LTE working!

I do believe that you need the HSPA radio to make phone calls as T-Mobile does not yet support VoLTE.

What are you doing for apn setting? There are 3 for tmo-us that I know of. 1)gsm 2)lte 3)lte ipv6. You may have to down load an apn app. Apn manager pro worked well for me or offline sim apn database. Not sure what you use for network mode settings but use build prop editort open it up and find the settings telephony.lteoncdmadevice & telephony.lteongsmdevice use value 1 on both. Add lines if not there. This may open up more network types under setting/...network mode. Google build prop edit or tweaks to find more info. Good luck.

i535 radio/modem
Been thinking about you question to swap modems. Do not use the i535. The modem that would be ideal I believe is the r530m. That is metro PC variant. T-Mobile merged with the.... Do I need to explain more? Any how I can not say it will even work. I will say that T999L is no good. Found out first hand and still dead in the water with it. I would explore the APN settings and network selection modes with build prop mods before flashing. I am not even sure about the LTE bands and who has what and where. If I am able to revive my 530u I will see what I can find.

Where can I get the r530m modem? Can't find it anywhere.

[Q] How To Manage Band Priorities?

How do I edit the band priorities?
Other phones' band priority settings can be edited with the ##DATA# > LTE menu, but this phone has only the LTE enabled/disabled option visible.
Is there a workaround, or is this a limitation of the phone?
Thanks!

Sprint N910P on Bell Canada's LTE Network!

I was able to get into the "Service Mode" main menu. Under option 2) UE SETTINGS & INFO then SETTINGS and finally PROTOCOL MENU. Option 2) NAS. Which shows LTE related stuff. The first option NETWORK CONTROL then option 5 "PREF MODE SET"
There I selected GSM_WCDMA_LTE and I was prompted to reboot the device. I did so and noticed the 3G still there not 4G or LTE.
I did a speed test (wifi not set up) on data with my providers LTE apn settings and my speeds went up. Before playing in the service menu I averaged 3.5meg down and about 650kbs up. Now I'm getting on average 12meg down and 8meg up!
I noticed a lot of other LTE related options in the service menu. Like band(s) and things. Does anybody know if I need to change any other options in the service menu to get true LTE.

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 ...
