Searching for a solution to my data connection problem I found this on the registry of my 8525 running WM6 vp3G v3 ATT
HKEY_LOCAL_MACHINE\Software\OEM\RIL\OperatorContexts
There are keys for about 20 operators named according to the MCC and MCN numbers, most of them have 2 DWORDs: "GPRSContextNumber" and "UMTSContextNumber". The DEC value for each varies from 1,2,3,4,7 and 10
My network doesn´t exist in the original registry, but appears once I insert the SIM card, however no DWORDs are displayed.
Does anybody knows what these keys are for? And how to obtain the values for my network?
Thanks!
Thanks

This entry really helped me so much...
the values identify how many conncurrent connections you can have for each connection type (UMTS and GPRS).
I located mine at HKEY_LOCAL_MACHINE\Software\OEM\RIL\OperatorContex\31040 (310410 is Cingular/ATT for me...wikipedia MCC MCN). Once I set UMTS to "2" (was "1" for both UMTS and GPRS) I was able to have both MEDIANET and BLACKBERRY Connect connections simultaniously over 3g on my ATT Tilt.

I've just realised that ever since I updated to GRI40, my 3g/EDGE/HSDPA connections don't work at all.
I've tried flashing radios 5.08, 5.12 and even 4.06, but it just doesn't seem to pick up my data connection at all. All I've got is standard connection, but no 3g/E/H icon to tell me that i've got a data connection...???

Saw this post in the First Impressions of GRI40 thread (see here).
I also have this problem. It's intermittent, but currently I'm at home, I turned off wifi, and my phone shows bars of signals, but no 2g/3g icon at all. Normally I can get both 2g/3g at home just find.
Tried turning off stuff like Juicedefender (worried about it messing things up). Rebooted the phone, toggled 2g/3g, nothing... Intermittent as earlier today I was using 2g and 3g with no problems...
Anyone else with this problem?
I'm on Rogers Canada, and am using a stock unrooted Nexus One.
Might have fixed it... was googling around. Right after GRI40 I had 2 APNs (I've never set them up.. there by default).
Replaced it with these values from this thread:

MNC: 720
This is obviously only a rogers fix, original poster who had this problem was Vodafone UK.. maybe APN problem?
I am having this issue, too. 3G doesn't work at all. I have to tell the phone to only stay on Edge and then it will stay connected. In fact if I uncheck that box, I lose everything including voice/text
I filled in the new settings in APN but im getting 2G instead of 3G ?
Anyone knows what i did wrong ? And the airtel "customer help" are not exactly helping me in any way.

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.

drawback of WCDMA only is if 3G signal becomes weaker calls will drop. as you know airtel has very amazing network

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!!

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!

Hey all,
Maybe some of you who are way smarter than me can look into this. A little background: Currently have 2 Essential phones on the T-Mobile. Ran one phone stock, upgraded to Android PIE out of the box, for about a week. Noticed it was having connection problems. The data would cut in and out (as reported by others). The signal bars were all over the place, full bars, no bars etc...
The second phone was unlocked and flashed to several different PH-1 roms, never updated to PIE. Noticed on almost all the roms when WIFI was turned on then off the phone would drop data LTE connection and it wouldn't come back. The only way found to get it back is to flip airplane mode on/off. Finally settled on AOSiP 8.1. It too had connection issues with the WIFI on/off:
https://forum.xda-developers.com/essential-phone/development/aosip-8-1-official-t3735143
In summary, both phones had signal problems, bars jumping all over. Both phones had predictable data connection loss after WIFI on/off and no SMS messaging. Only Airplane mode would restore data and SMS.
Here are the current base-bands of each phone:
Phone1 (moon black,AOSIP): 2.0.c4-M2.0.3
Phone2 (halo grey, had PIE for a week, but now on AOSIP): 2.0.c4-M1.3.1
Ok now for the fix (?). Made a few changes to Phone1. Signal is almost full bars, and it doesn't drop signal after WIFI. SMS works fine. If fact its been working fine all day with no issues. Here are the changes I made to both phones:
Made the following changes on both phones:
1. Turned off Enhanced LTE Mode
2. Set Preferred network type to LTE/WCDMA
2. Removed all APN's except for T-Mobile, with the following:
APN: fast.t-mobile.com
Proxy: none
Port: none
Username: none
Password: none
Server: none
MMSC: http://mms.msg.eng.t-mobile.com/mms/wapenc
MMS proxy: none
MMS Port: none
MCC: 310
MNC: 260
Auth Type: none
APN TYPE: default,mms,supl,hipri,admin,mobile,dun
APN protocol: IPv6
APN roaming protocol: IPv6
Bearer: unspecified
MVNO type: none
In my testing I found that setting the APN protocol to IPv6 seemed to be what fixed the WIFI bug. Stock it was set to IPv6/IPv4. So far so good. Phone1 one has been solid all day, no connection issues. Using bluetooth headset, WIFI etc.
Now I'm confused about Phone2. It has the same settings, and the WIFI bug is gone, and its also working almost all the time. The only problem it has now is if I let it sit for 20min or so, the data connection gets lost and have to use Airplane mode to get it back.
Summary: Both phones were having signal drops and data connection issues on T-Mobile. Doing the above steps solved all the problems on Phone1. It has perfect signal and has been working fine all day. I can't break it. Most of Phone2's problems have been solved, except when it goes to sleep it looses data connection and I have to use airplane mode on/off to fix. Both phones are identical except for the baseband.
Anyone know where I could find the baseband that’s running on Phone1 so I could flash to Phone2?
Hope this is of some help to those of you on T-Mobile and having signal problems.

Noticed on almost all the roms when WIFI was turned on then off the phone would drop data LTE connection and it wouldn't come back. The only way found to get it back is to flip airplane mode on/off. Finally settled on AOSiP 8.1. It too had connection issues with the WIFI on/off:

In summary, both phones had signal problems, bars jumping all over. Both phones had predictable data connection loss after WIFI on/off and no SMS messaging. Only Airplane mode would restore data and SMS.
Here are the current base-bands of each phone:
Phone1 (moon black,AOSIP): 2.0.c4-M2.0.3
Phone2 (halo grey, had PIE for a week, but now on AOSIP): 2.0.c4-M1.3.1
Ok now for the fix (?). Made a few changes to Phone1. Signal is almost full bars, and it doesn't drop signal after WIFI. SMS works fine. If fact its been working fine all day with no issues. Here are the changes I made to both phones:
Made the following changes on both phones:
1. Turned off Enhanced LTE Mode
2. Set Preferred network type to LTE/WCDMA
2. Removed all APN's except for T-Mobile, with the following:
APN: fast.t-mobile.com
Proxy: none
Port: none
Username: none
Password: none
Server: none
MMSC: http://mms.msg.eng.t-mobile.com/mms/wapenc
MMS proxy: none
MMS Port: none
MCC: 310
MNC: 260
Auth Type: none
APN TYPE: default,mms,supl,hipri,admin,mobile,dun
APN protocol: IPv6
APN roaming protocol: IPv6
Bearer: unspecified
MVNO type: none
In my testing I found that setting the APN protocol to IPv6 seemed to be what fixed the WIFI bug. Stock it was set to IPv6/IPv4. So far so good. Phone1 one has been solid all day, no connection issues. Using bluetooth headset, WIFI etc.
Now I'm confused about Phone2. It has the same settings, and the WIFI bug is gone, and its also working almost all the time. The only problem it has now is if I let it sit for 20min or so, the data connection gets lost and have to use Airplane mode to get it back.
Summary: Both phones were having signal drops and data connection issues on T-Mobile. Doing the above steps solved all the problems on Phone1. It has perfect signal and has been working fine all day. I can't break it. Most of Phone2's problems have been solved, except when it goes to sleep it looses data connection and I have to use airplane mode on/off to fix. Both phones are identical except for the baseband.
Anyone know where I could find the baseband that’s running on Phone1 so I could flash to Phone2?
Hope this is of some help to those of you on T-Mobile and having signal problems.
######### UPDATE#########
Sorry, found the radio's here:
https://forum.xda-developers.com/essential-phone/development/stock-7-1-1-nmj20d-t3701681
Flashed the Package without boot: PPR1.180610.091 AFH (latest pie 9.0 august) to Phone2.
New baseband on phone 2 is 2.0.c4-m2.0.5.
Will get back to you on if it solved all my T-Mobile issues.
But why didn't the baseband get updated with the official OTA update to PIE?

please keep us posted.
Setting roaming to IPv6 is likely to cause a *large* number of roaming providers to fail connections. If you never actually roam you may not care, but if you do....
The "factory" setup in the SIM and firmware for Pie on my Essential has IPv6 only for native on the "FAST" APN, but IPV4 for roaming -- which is what I've seen on other devices and used on T-Mobile for the last several years without problems. I also have no issues with mobile data disappearing and not reconnecting when I go on and off WiFi.
Additionally setting the bandplan to LTE/HSPA will prevent 3g (and 2g) connections from coming up at all in my experience. I ran it there for a bit but put it back to "Global" and have better results in marginal service areas -- a slow connection is better than none!

Hey all,
Since my original post I've only had signal problems twice, which a simple air plane mode fixed. I am not able to reproduce either.
The radio upgrade made a huge difference.
And we don't roam where we are, so roaming isn't an issue for us.
