Mobile network/signal drops help - Samsung Galaxy Nexus

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?

[Q] Android GSM Radio

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.

[Q] Not getting 3G/4G

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.

[Q] SGH-I747 how to enable 3G and 4G

Hello Guys.
I live in Macedonia and cant enable 3G on VIP Operator or 4G on T-Mobile MK.
I have AT&T Samusng galaxy S3 SGH-I747 US Version, ROOTED with new ROM.
-The signal strenght is: -53 dBm 30 asu.
-Mobile network type: EDGE
I tryed with *#*#4636#*# and select LTE/GSM/CDMA auto (PRL) and again still no 3G.
PLS HELP or i will must to sell my phone
Do those carrier use AWS frequencies like T-Mobile in the USA? If they do, you need to enable AWS in the i747.

I fixed but only work on T-Mobile SIM card and its 4G network, the VIP network and ONE network is 2G. At least work on 1 network good
Thx a lot anyway.

VS986 to use band 5 LTE abroad.

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.

Unlocked sprint g8 no 3g or hspa

Im using this phone with cricket but for some reason it won't connect to 3g or hspa do anyone know why?
Perhaps because regular 2G, 3G or the faster 3G HSPA(+) on AT&T's network runs on GSM technology which is completely incompatible with the CDMA network Sprint uses for those technologies and the firmware on the Sprint variant is artificially limited to only be able to connect to CDMA and not GSM even though the phone's modem has the capability? Take what I'm saying with a grain of salt however.

Yes, because LTE is its own technology. LTE, GSM and CDMA are each their own technologies, each completely different from the other in a multitude of ways. That's what makes one not compatible with the other, but with the advent of LTE it also made it much more cost-effective for device manufacturers to include 4G support for all major networks (provided the device supports the necessary bands and the carrier allows it, of course)... so yes, LTE should work flawlessly.
The specs on the LG Official Website for Sprint LG G8 shows it has all the 2G, 3G, and 4G bands on Cricket except it's missing B30 for 4G:
LTE Bands 1/2/3/4/5/7/8/12/13/17/20/25/26/28/40/41/46/66/71;
CDMA Band Class 0/1/10;
GSM 850/900/1800/1900 MHz;
UMTS Bands 1/2/4/5/8
Did you try to change the network mode to GSM/UMTS and reboot?

Yeah thats what I thought too but even after changing the network mode and restarting still not getting 3g data
Yes you can dial *#*#4636#*#* , go to phone information or network, look for preffered network, then select wcdma preferred, it will switch to hspa+, do note there will be no indication, only a 3g symbol on the bars. if you download network info app, it will let you see that you are indeed on hspa
Ok after many attempts to bring up my 3g inwas able to do so by going into ##data# and resetting the apn then boom 3g icon popped up. Weird because the apn was correct in the first place prior. But thanks now it works

LTE. If you don't get good speeds (about 10Mbps) then change it to GSM. This is something I actually have to remember to do if I'm outside the house because I actually get more consistent performance inside my house using 3G HSPA+/GSM. On HSPA+ it goes to is 6Mbps which is plenty usable but normally it runs at 10Mbps which is more than enough for Full HD streaming whereas if I use 4G LTE under the same condition I'll either get 30Mbps or 1Mbps depending on the time of day and/or if the network is congested. 1Mbps is definitely not usable for anything but streaming at horrible quality or browsing basic webpages.
