I just wanna know if this detail is right on my preferred network phone settings.I've got WCDMA (Preferred) selected,while other settings like GSM/CDMA etc were not ticked. Is that the right settings "WCDMA (Preferred)" for a mobile network in UK and on 3UK network?Thanks
WCDMA is also referred to as UMTS which is the technology behind 3G, so WCDMA (preferred) simply means that it will use 3G when it can.
oh,cheers for that.Now I get it
There's no way to toggle LTE on and off is there?
I'm about to go to a place with just HSPA+ at most and don't want my battery ate up looking for an LTE signal.

Choose WCDMA only or GSM/WCDMA

Hi guys can you tell me how to turn on wcdma preferred ? I need to know this. Thank you
Do you want WCDMA preferred or only WCDMA?
Go to dialer and type *#*#4636#*#*, select the top option (phone info). There you can choose the preferred network type.

Heh
Speed Differences & Non-Sticking of "Preferred Network Type" *#*#4636#*#* and b prop
When speed testing on the "preferred network type" of LTE/CDMA/UMTS auto (PRL) I get an average speed of 9Mbps. When I change it to "TD-SCDMA only" I get an average of 21Mbps. I would like to keep it as TD-SCDMA but when exiting it always reverts back to LTE/CDMA/UMTS auto (PRL). In the settings on the phone under mobile networks it only allows me to select LTE, 3G, and 2G. When setting it in the build prop under ro.telephony, I have it set to 13 which is "TD-SCDMA only", it does not stick either. LTE/CDMA/UMTS auto (PRL) is the one it always defaults to no matter what. My network Carrier is ATT, the phone is unlocked and rooted. Can anyone offer any solutions?
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)

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 ...
