[Q] How to change bands - G2 Q&A, Help & Troubleshooting

My G2 D802 Lollipop rooted struggles to get 3g. I think it needs to be set to 900mhz. When I go into hidden menu its say WCDMA 850, I can click 900 and it says success but I dont think it saves as it says 850 at the top of that menu all the time. I have to have my phone set to GSM only as if I have it set to GSM/WCDMA it is always looking for 3g and cant find it so it keeps disconnecting my GSM/2g for a while.

i just used app called LG Phone From, and its brings up info about my phone. It says provider is United Arab Emirates, and network type GSM. Is this why i cant connect to 3G 900 and 2100 here in New Zealand properly? How can I change this?

First of all, you can only change 2G and 3G network bands, never 4G.
Now, to change the band you need 3 things ( 4 maybe ):
- The modem drivers for your zone.
- Custom bootloader to change it.
- An AOSP ROM ( official roms check modem and rejects 'cause it doesn't match ).
- Maybe one ---> Android Kitkat ( As far as I know Modem drivers on lollipop aren't compatible between themselves )
Bests of luck! :good:

Thanks, sounds like its going to be difficult. I will have to look into all that. I am not worried about 4g coverage, I just want 3g to work properly.

So I tried 3 different modem flashes, (2 x UK and 1 x Asian) that use same frequency as here - 900 and 2100. but they just behave the same, good 2g but no 3g signal. I just used modems that worked with my stock lollipop 30a and flashed them with twrp

Additional info, when i select gsm/wcdma/lte auto or anything else other than GSM only, it connects to G (wont go 3g or H etc) but as soon as I try to dial out it loses connection and I cant dial out, or recieve calls. Only option at present is leaving the phone set to GSM only so I can use it. as well as flashing a few different modems i have tried altering the telephony build prop number to 11 and 13 as suggested in other threads.

Did you configure the HSDPA/3G APN manually? For example here, on Argentina Claro:
Nombre: Claro AR
APN: igprs.claro.com.ar
Proxy: No definido
Puerto: No definido
Nombre de usuario: No definido
Contraseña: No definido
Servidor: No definido
MMSC: http://mms.claro.com.ar

Puerto de MMS: No definido
Protocolo MMS: WAP 2.0
MCC: 722
MNC: 310
Tipo de autenticación: No definido
Tipo de APN: default (si no se puede ingresar, seleccionar Internet)
I had to do it to get the 3G signal, otherwise the phone doesn't know where to connect to.

Bougtel: 3G issue?

Hi everybody,
I've got a problem with my 3G connection.
I've updated it with the last one, but I can not use my 3G connection.
What should I setup or configure to found an issue?
My operator is Bougtel (France).
Thanks to any advise.
Best Regards,
M.M.
same problem as you.
if you have any feedback I'd be glad to have them as well.
for info, I'm bouyguestel as well, in Paris with supposedly the right parameters and I only have EDGE connectivity.
Hi, I'm on bouygtel too and I have no problem with 3G.
My APN was auto-configured as soon as I had my data plan activated.
Here is what I have in my APN settings :
Nom : Bouygues Telecom
APN : mmsbouygtel.com
MCC : 208
MNC : 20
Type d'APN : default,supl
The supl parameter in APN Type section was added by me to activate, I think, the agps data.
Hi,
I hqve the sqme parameters and it seems to be working fine. It's still a bit weird because in Paris, where it should have 3G everywhere, there are still some spot I don't get it.
... let's hope for more patches.

Airtel 3G APN Settings

For Airtel mobile office your settings are ok just remove proxy and port. if you are trying to setup airtel live then apn should be airtelfun.com and proxy and port remains. most of the android phone will not display 3G instead it will show H for HSPDA. if 3G signal is weak it will switch back to edge and will show "E". try changing the mode to WCDMA only. then check.
as an alternate give these a try for data.
1. Homepage – any page you want to set.
2. User Name – Blank
3. Password – Blank
4. Proxy – Enabled/yes.
5. Proxy and Server Adress – 202.56.231.117
6. Proxy and Server Port – 8080
7. Data bearer – GPRS or Packet Data.
8. Access Point Name – airtelgprs.com
9. Authentication Type – Normal
10. Use preferred access point – No
Even I am having the same problem. My settings are correct as stated above but I am getting only 2G. 3G hasnt come up even once and I have travelled over 20 Kms across the length of Bombay, so coverage cannot be an issue. Do I need to change anything else?
Open Dialer and type this *#*#4636#*#*
Select the drop-down that says "Phone Information". From there, scroll down to where it should say "WCDMA preferred", and change it to "WCDMA only". Use the back key to get out. now check if your phone is able to detect 3G network. once it connects to 3G and you see H.
Airtel has worst network in mumbai so for phone to stay connected on 3G network signal strenght should be above -125db or else phone will switch back to 2G network. may be because of low signal stength you are not able to get 3G

Hey Smokin,
I tried this method to force WCDMA mode on my Samsung Captivate, but had no luck getting the 3g symbol on my phone. Instead I still have the E symbol for edge.
I have been trying since Saturday to get Airtel to put their 3g service on my phone, but had no luck. I went to a Airtel shop yesterday here in Manipal to get 3g manually activated on my phone. That didn't do any good as well.
I believe like you said that the problem isn't the activation aspect of 3g, but rather the signal strength for 3g is too low to be picked up by android phones. When I went to the Airtel shop the other day I noticed that most of the people there with working 3g phones had either a blackberry or iphone device.
If this is actually the case, I have no choice but to switch to another cell phone service provider who provides 3g service with a "android-friendly" signal strength. Is there such a thing?
Can you try with any of 3g enabled handset to see if you get 3g network in Nokia phones like n95 it should Show 3.5g. Also was your phone able to see Airtel network in wcdma only mode.
Sent from my HTC HD2 on andriod using XDA App
Hey,
I don't have any other handset with 3g capability nor do my buddies here. When I put the phone in WCDMA mode, I didn't get a signal for the GSM Airtel Network.
Apparently other Galaxy S owners have been having problems with Airtel's 3g network (Read at the comment section below: mobilegyaan.com/airtel-3g-karnataka-price).
Maybe Airtel will resolve this soon?
Edit: 3g is working now on my handset with Airtel network in Manipal.

Airtel launched its 3g service in Hyderabad today. And I was facing similar problems as others here. Selecting "WCDMA Only" did the trick for me and now I have the 'H' symbol on my HTC Wildfire.
However, I checked the signal strength and it is displaying -81dBm 16 asu. Does this mean I won't be able to access 3g with "WCDMA preferred" selected as I often roam and would like to fall back on 2g in the absence of 3g signal.
Also, will the above mentioned signal strength affect the call quality in any way?
Thanks for your help..

-81dBm is greater than -124dBm it is a good signal strength. problem with WCDMA only mode is if there is no 3G signal there will be no service. best would be to keep on on WCDMA prefered.

Which Handset and rom?
drawback of WCDMA only is if 3G signal becomes weaker calls will drop. as you know airtel has very amazing network
Location - Hyderabad
Mobile - Samsung i9020T
Stock ROM - 2.3.3

Just change APN to Airtelgprs.com instead of airtelgprs.com (capital A for small a )

hey smokin i have nexus s....airtel....my phone shows 3g symbol but i get only 2g speed...i did as u said....initially it was selected to gsm/cdma auto(prl) and i changed it to WCDMA only...still no change....signal strength is -83db...can u help here?
Not to sound like a completely dumb guy, but I have a Nexus One and resolved my issue by texting "3G" to 121 on Airtel. That activated 3G service and with the APN settings above, I started getting HSDPA speeds.
Hope that helps someone. Took me an hour to find that part....
So i activated 3g n put a 3g pack...
Galaxy fit..... But this goddamn Airtel gives me like 15kb/s in new Bombay....... Calling those jerks CC Temme some Bull**** that Airtel operating 3g In Maharashtra on Vodafone and Idea networks... Tells me to manually select Vodafone or idea network! (absurd! Airtel Sim registered on Vodafone network )
So i try that also... Speed 20kb/s...
Bharti mittal should resign!!
Get a Vodafone Sim... I get like 4.84mbps on cell which is terrific!!

[Galaxy S Captivate] - 3G problems (plz move to Captivate General Forum)

Hi everyone! Good evening!
I have a SAMSUNG Galaxy S Captivate AT&T unlocked FROYO (thanks to you guys!) working fine in many carries here in Brazil. But when I try to use the TIM GSM card the 3G doesn't work properly... The 3G icon appears on the screen but no data seems to be transffered... No web no program connections... The phone calls are OK. TIM Brazil operates with HSDPA 3G that is supported by the Captivate ( Am I right??). The APN's config are fine.

The Service Provider (TIM) said that is everything OK in my area and I should look after for SAMSUNG solutions because they don't configure Android... SAMSUNG told me search for Service Provider solutions...
It seems I'm alone in the dark... Someone may turn the lights on!?
Could this problem of recognition of the correct name of the Operator be causing the lack of connection?
Thanks since now for the support and attention.

For some reason, in every ROM for L7 (at least CM based), the 3G doesn't work. I still have to try 3G on stock to see if it is a problem of the ROM or the phone but after some searching, I found that I'm not the only one with this problem. I have tried going to *#*#4636#*#* menu and forcing the phone to WCDMA only but that makes me have no network service at all, only if I put it to GSM only it will work. Is there any fix for this?

Contacted my network provider, and I configured the APN correctly as they told me, still don't get 3G, only H. It's set to GSM Auto PRL since I can't set it to WCDMA preffered, so it should be getting 3G, but I can get 3G basically nowhere in my country while my old phone (Galaxy Gio) could get 3G almost anywhere in my country.. don't know what's going on on
By the way, in the Phone info (*#*#4636#*#*) menu, when I change to WCDMA preferred, it always goes back to GSM Auto (PRL) by itself. Does the problem have to do with this?

H stands for 3G HSDPA which provides theoretical speeds up to 7.2Mbps.
3G stands for 3G UMTS which provides speed to 3.6Mbps (not sure)
Its better to get H than 3G. But both stand for 3G.
Some ROMs show H, some show only 3G (like Jelly Bean Mini Project), and some show both ...
It is best to set to Auto Mode (GSM/WCDMA) or 3G preferred, rather than 3G only because in some areas where 3G isn't available, battery will drain high searching for network. In that cases, if in Auto Mode or 3G preferred, it will latch on to 2G and back to 3G when you get 3G coverage!

OPT US Version can't connect to T-Mobile LTE in NYC

Hi,
I live in NYC.
I just switched to T-Mobile today from AT&T, but now I can't get a LTE signal. I can make phone calls, send sms/mms, and even surf the web, but only with a H connection.
I can confirm my location has T-Mobile LTE since we also have an iPhone 7 on T-Mobile and with Ookla speed test the iPhone 7 is getting 38Mbps down.
I called T-Mobile tech support twice, they did refresh multiple times, still no LTE signal.
I am using the following settings:
APN: T-Mobile US LTE IPv6
Preferred network type: LTE
Network operators: auto
Mobile data: ON
Thanks in advance!
I'm using
T-Mobile US LTE
fast.t-mobile.com
APN roaming protocol: ipv4
APN type: default,supl
Preferred network type: LTE/GSM/WCDMA
System select: automatic
CDMA subscription: RUIM/SIM
Probably more details than you need but that's how I'm getting 4G. 68/22 speeds
