Hello everybody!
Just figured out that my new Tab S 8.4 AT&T (SIM unlocked) seems to be locked to WCDMA only (HSDPA).
Where I live there's 4G coverage, and it was always working OK, but now went overseas, and when I have only EDGE coverage device shows "no network".
I downloaded "Advanced Signal Status", and when I change to "WCDMA preferred" (or any other option, like "GSM only") - it doesn't do anything, returns back to "WCDMA only", seems to be locked.
Anybody experienced this?
I also have AT&T Galaxy Note 8 (SGH-I467), same SIM works there correctly, changing to GSM mode (EDGE) when not in 3G/4G coverage area.
P.S. My T707A 4.4.2 is rooted with Kingroot 4.5, then treated with SuperSU Me Pro.
Will be glad to hear any comments.
Solved?
Update: I think that I figured it out, looks like AT&T ****ed up this nice device as well (surprise, surprise), making GSM only tri-band 700/850/1900, leaving out 900MHz (which is exactly the band I need for GPRS/EDGE here).

I am on Wind, a new Canadian 3G AWS only network that defaults to (roams) Rogers GSM when the signal is weak. I have noticed that the sensitivity on WM 6.5 seems to be much more better than on Android in that I can select Wind inside my home in Windows but the Phone will not find Wind as an available network on Android. I have not selected "2G networks only". I would have assumed that the Android build uses the same radio software.
It uses the same radio firmware if that's what you mean. Hardly the same at the software level...
Either way with Android you get a choice - GSM or CDMA. You can't flip between (to my knowledge...) while in the OS as you have to change that value in the startup.txt to get either GSM or CDMA service.
I think there may be a way to adjust startup values on the fly, but it's certainly not straightforward as I recall. I'll see what I can drum up, but that is your problem I believe.
Thanks, some more background: Both networks are GSM, one (Wind) 3G on 1700 and 2100 and the other standard north American 2G GSM (850 and 1900). As far as I know the roaming agreement does not allow my phone to use the 3G part of the Rogers network. The phone is originally t-mobile GSM - otherwise it would not work on Wind.
I really do not think that CDMA comes in to the equation.

Ah, I misread your post. I apologize... not sure what you would need at this point but I'm not sure anyone else is doing what you're trying to do... Hopefully someone who is chimes in
Android GSM Radio
@arrrghhh
I probably did not state it clearly.
I have a t-mobile (US) Touch Pro 2 that is unlocked. When I use it in WM 6.5 at home I get to select the Wind network as an option. When I use the phone in Android mode I do not get to see the Wind network at all but only the Rogers network that Wind roams on as the Rogers network is much larger than the Wind network. Is the problem with less sensitive GSM radio software or are there some selections such as "data enabled" or "2G network only" that I have not made correctly?
I don't believe so, and I've heard GSM reports what service it is getting from the tower ID - so perhaps the towers you're connecting to are still Rogers even tho Wind probably leases tower space from them...
Unfortunately I don't have this ability, and I'm not sure anyone else uses GSM in this manner - I'll poke around and see if I find anything that is useful.
I recently changed services from AT&T to T-Mobile but kept my same number and phone. I rooted my phone as well installed Cyanogenmod 10 but now I am only getting edge network and I reported to T-Mobile and they could not help me since they did not know how to repair it and told me I am suppose to be on 3G/4G network since my area has perfect coverage for 3G/4G. The phone is unlocked to use T-Mobile SIM card.
My mobile network settings is set for
Network Mode: GSM/WCDMA preferred
APNs: T-Mobile US
Data enabled
Data Roaming
National Data Roaming
Is there something I missed to do?
try change
Network Mode to LTE/GSM/WCDMA

I already tried that and so far it still hasn't changed into 3G/4G.

You may be in an area not covered by T-Mobile for UMTS/HSPA/HSPA+ service on bands 850/1900 MHz.
T-Mobile usually has its 3G/4G service on 1700 MHz AWS frequencies. The SGH-i747 has an antenna for the LTE service on 1700 MHz, and it is not used for HSPA/HSPA+. Currently, T-Mobile is refarming its 1900 MHz spectrum to run HSPA/HSPA+; you can use this user-generated map to see the refarming progression.

I'm on stock rom, I'm with wind mobile, when I go to mobile networks to search for a network it comes up with "WIND Away" I cannot get WIND Home where i can't make a call at all right now. my model is i9250m which is suppose to work with wind mobile, I've used this phone with wind but after i factory reset, it's not not working. any help would be appreciated.
Make sure your phone is not set to use "2G only".
Wind Away = Rogers (2G and 3G)
Wind Home is 3G only
Galaxy Nexus supports Wind's 3G band (UMTS band 4) so it should work. Are you in an area with confirmed Wind (home) coverage?

I've I'm on the 30$/m plan unlimited data call etc , and it always worked on my RAZR v. Today with the Sim in i brought it around with me and i noticed that i had siginal and it kept dropping and now i have no more siginal? any ideas?
I meant to use band 5 lte in indonesia with smartfren using vs986. I used shortcut master lite app to enable band 5 (and/or disable irrelevant lte bands). However i still cant connect to it. I am certain that my location is under that lte band 5 coverage given that when i used other gsm sim i could see the network and attempt a registration on the network. Furthermore, seeing the networks rat id also match with the information online that it is indeed a band 5 lte network. However when i pop in the band 5 lte network gsm sim card, i am no longer able to scan for networks, it just fails to scan everytime, thus i cant connect. I wonder if there is a workaround to make vs986 able to connect to other lte networks other than verizon.
P.s. im on slim 13b rooted/xposed.
It's not just the bands. Verizon really borked the firmware of the phone to make sure that it doesn't work on any other 4G LTE network than its own. For instance, it doesn't work on AT&T and T-Mobile LTE network in the US either, even though the bands are supported.
What you can try is to switch the phone to "LTE/CDMA" mode in the "Network mode" settings. This will probably kill your phone connection, but if you get 4G LTE then, then you can try the same hack that worked for T-Mobile: http://forum.xda-developers.com/verizon-g4/general/guide-fix-vs986-dropping-to-3g-h-4g-lte-t3272434
But on some networks, there is no hope, for instance nobody was able to get it to work on AT&T.
I think i did check that thread out when i used t-mobile for about 6 months in seattle/udistrict/uvillage/uw areas, with no success. I never got the LTE connection. I wonder maybe its related to different roms/kdz/flashfire modified version of 13b that cause it. I hope someone whos lucky enough to get lte might share info about their 13b version/softwares that you debloat using debloater or froze using tibu. Thanks.
P.s. it was on 4g for an instant before it gives me no signal/network.
Why would VZW disable B5 if they have B5 sites?
That would really be stupid.
Posted using a calculator and delayed by AT&T.
LTE 2/4/5/13 can be activated using Shortcut master lite. The problem is that, when i used a simcard that utilized LTE band 3/8, i could detect/attempt registration to signal from LTE band 5 from local network through GSM (given that i activated it). However when I used simcard for that LTE band 5 network, somehow, i can no longer use gsm/cant search for network/crashed. It seemed that LTE antennae on this device is programmed to only accept verizon's. (For lte networks, apns are saved when i put MCC/MNC or RAT for verizons, but discarded when i put other). Thank god though i could still use umts/3g.
Edit: So i tried again. Turns out, i could to get registered on the network, checked on network type and strength (says 4g - 3/4 bars) also on lte discovery says connected. However signal bars says unable to connect to network. Verizon definitely prevent users to use lte on another network. What a **** company.
this is from Verizon website them self
Network
CDMA, GSM, LTE*
Frequencies
1.9 GHz CDMA PCS, 800 MHz CDMA, GSM 850/900/1800/1900 MHz, LTE 2/4/5/13, LTE 3/7 for Roaming*
which show it support band 3 in case of romaing only..but if you are in USA will not work sure as it is not romaing.
Hi
I just came back from a trip to Bangkok and noticed something unusual about the phone which I've never encountered before. I have a US unlocked HTC 10 and am on T-Mobile international roaming.
By default, my Preferred Network mode setting is "GSM/WCDMA/LTE auto". This setting works when I'm here in the US. While I was in Bangkok, the 4GLTE icon would be on but I would never be able to connect to the internet. However, when I switched it to WCDMA only, the phone was then able to connect. This seemed to happen whether I was connected to AIS or DTAC (the local wireless carriers).
By comparison, my friend's iphone x, also roaming on the same tmobile plan, didn't have any issues.
Any clues why this would be happening?
