GPRS / UMTS Operator Contexts Numbers - Networking

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.

How to enable Band Selection in Phone Settings?

Does anybody know which registry key to change or make in order to have a Band Tab under Phone Settings?
Band Selection Tab in Phone Settings on HTC Wizard?
Those that have the Band Tab in Phone Settings of WM PPC Phone, would you please do me this favor posting the registry details of this entry: : HKLM\SOFTWARE\OEM\PhoneSetting
My device has ShowTimeZonesPage and ShowPIN2Page only. I wonder if one has got something else. Still working on adding this Band Selection TAB.
Thank you in advance!
I would also appreciate this information. My 8525 keeps latching onto UMTS at a very low signal strength. I'd prefer to disable UMTS at times. Thanks,

Rogers Wireless and Band Switching

This is a question to all the Rogers Wireless users:
Does anyone know if Rogers locks their phones to 3G; or more accurately, if they set their phones so the user can't manually force GSM?
I ask because I've been trying (and failing) to find a way to set my HP iPAQ 910c to lock into GSM mode in order to save battery life. My phone settings panel lacks the "Band" tab some resources I've found talk about that allows changing of radio band, and I've tried a number of registry tweaks an an attempt to enable the tab so I can specify GSM network to no avail. The best I've been able to do is get DHR BandSwitch to set a timeout on my data connections, which helps a bit.

Uk Vodafone customer can surf in Hsdpa but can't connect to G

Hi All,
As UK Vodafone CS were no help what so ever...I thought I would ask the experts.
I recently updated my phone via Sony Update software to
R3AA013
At home all seemed fine I created a new wap and connection and setup email etc and on the 'H' network all was fine.
Unfortunately at work I have a weak signal and only ever get G. Problem is now the phone seems to be unable to connect to this, just seems to cycle through attempts then gives up.
Is it best to reapply the firmware update and start again or are there any settings I can check first?
As I say in the HSDPA signal is seems to work fine...
Thanks in advance!
Paul.
Personally i have only got a 3G signal in Crystal Palace but no where else - i sometimes see H but that is always a very low signal and sometimes G with a high signal - dont know which is better - and yea im not to sure about G working either - G isnt 3G though 3G=3G but yea it would seem vodafone suck and their CS is more than awful and rubbish

I very rarely see the 3G symbol too. I normally get H and G. I just walked out the office and the G went to H and I could get pages again. Does anyone know what is going on?
try next time u r at work going into "settings", "connections", "advanced", "select network" - and switch settings there from My ISP to WEB - then try connecting again.
I had the same problem for a while and this helped. However, occasionally I have to switch around when I m in an "H" signal area. Dont know why that is but I guess its not the only weird thing about this phone
Hi Amanox,
Thanks...I tried that work around, it shows the solid G and two dialled connections but when you try and access a page on IE or Opera... both say they can't locate remote server.
It's really frustrating.
Regards,
Paul.
When is shows GPRS (G), it may be that the Vodafone cell-sites (transmitter pylons) transmitter cards do not have the capacity to allow data over that frequency, whereas the 3G/3.5G (HSDPA) transmitter cards have ample bandwidth?
Just a sort of educated guess. Either that or something is screwed up in your account settings at Voda's end not allowing it.
I don't have this problem at all ...I get 3G or HSDPA most of the time in London -GPRS is the fall-back I think, when neither of the faster options is available.
What puzzled me, and I thought it might just have something to do with your issue, is that you mention manually setting up networks:-
"created a new wap and connection and setup email etc"
I do of course have tp set up Email, but have never had to set up wap or anything else ...when I've hard reset (upgrading ROMs etc -am now on R3A too) I have only ever had to enter my SIM / PIN code and that's it -I'm connected to 3G (or H or G depending on what's available)
Nothing set manually at all -other than email account (and WIFI/bluetooth connections)
My guess is that you have chosen the wrong APN. As I'm from Germany I do not know the correct setup for Internet access in the UK, but Vodafone Germany differs between WAP and WEB access as well. WAP access is really limited to a special bunch of sites, so maybe your problems are related to an incorrect setup of the APN.
Jcsxda, sorry to puzzle you. I created a Manual internet profile and a Wap connection profile as I can't edit the My Isp one the phone came configured with. I thought by creating it manually it might fix the problem. I used a Vodafone configuration guide for the SONY X1 so I must have the right APN's etc.
Foo you mentioned the APN might be wrong if that was true I would assume I would not see any connections. When I tap on connectivity info box I see a Voda INT (GPRS, 3G) and a contract WAP (GPRS, 3G) both with a timer counting up. I have set that programs that use the internet use the standard My ISP, then for programs that use a private network I have told it to use the manual connection which I setup using the UK Vodafone configuration guide.
Oh and I re-installed the firmware last night, but still have the same problem.
G, 3G and HSPDA are pretty much the same thing in terms of connecting. It's just the speeds they run at.
GPRS is around 56 kbit/s
3G (UMTS) is around 384 kbit/s
HSPDA on Vodafone UK is up to 7.2 mbit/s (although a lot of cells are at 3.6 and some are at 1.8)
Vodafone Greece have just released HSPA+ with speeds of 21.6 mbit/s.
In the UK most 3G cells have been upgraded to support HSPDA, so if your phone supports HSPDA (the X1) then you will find it rare to come across the 3G symbol.
I switch between using both the WAP and the INTERNET apns (images better on WAP, however more apps run on INTERNET), and switch between G and H through the house and never have a problem.
I would suggest making sure that the settings are 100% correct.
The INTERNET apn is the easiest as it doesn't need any proxy settings.
The apn is internet and the username and password are both web

Hi Artesea,
Please correct me if I am wrong but if I had the APN's details wrong wouldn't I be unable to surf in H areas? Which I can. It's only when just the G is displayed I can't get any access. The manual connection I created I have not added anything other than.
internet

The crazy thing is it was all happy before I installed the firmware update..although the connection has always been weak I did get a connection at work.
Maybe I should just be happy I can still get phone calls and spend less time looking at my email...
The wap apn sometimes need (and therefore it is advisable to have) some extra proxy details.
You should have ticked "This network connects to the Internet" and "This network uses a proxy server to connect to the Internet" with "212.183.137.12" as the Proxy server.

[Q] nexus 7 3g confirmed working on 850mhz?

Hi, I am having a strange problem with my nexus 7 3g. I am in Thailand trying to use 3g on the truemove-h network. I have read that in some areas here the 2g/3g service operates on 850mhz.
If I put my sim card in an iPhone it shows the 3g icon and data works OK. However if I put the sim in the nexus it actually shows that I am roaming and I can't access data even though I have enabled the roaming option.
I have previously used this sim in the nexus successfully in other parts of the country but I think it was using a different frequency.
So my question is can anyone confirm that they have used 3g on the 850mhz frequency?
I have done obvious things like checked APN, balance, etc.
Hi , You can use 3G 850Mhz with Asus Nexus 7 3G 32GB too. Now I use Nexus 7 3G wit Truemove-H. You have to set up APN ,before you are going to use internet with your device.
1. go to Setting
2. go to Wireless and Network
3. choose Mobile Networks
4. Select Data Roaming too.
5. choose Access Point Name
6. click 3 Points on the bottom
7. select New APN
Set as following
Name = TrueH Internet
APN = internet
Username = true
Password = true
MCC = 520
MNC = 00
Authentication type - PAP or no need to set is ok.
APN type = default
select back , will be saved automatically.
Enjoy your Nexus 7 3G in Thailand.

T-Mobile MMS Fix over 4G LTE

I have heard that people using the MT7-L09 version of the Ascend mate 7 are having issues sending MMS Messages over Cellular network and the only way you can make and receive them is over Wi-Fi. Well the issue is Really common on Internationally unlocked cellular phones and the issue is really simple to fix. The problem resides in the APN Settings. When you pop in your T-Mobile or AT&T SIM card, the device sometimes sets up a Automatic APN Set up within the device. Sometimes, when the device does this, it puts down incorrect or old values. Now to the fix.
GO into Settings. Under Wireless & Networks tap More, then tap Mobile Network, and then Access Point Names. Under general you will see a already preseted APN called T-MobileData and under MMS something called T-MobileMMS. If you click the "i" next to the T-MobileData APN you will see that there is nothing set under the MMSC. To add the MMSC value just tap the value and type in http://mms.msg.eng.t-mobile.com/mms/wapenc
After that tap OK then go down to APN Type and make sure default,supl,mms,hipri,dun is displayed. If not, add in the missing values. Make sure that mms is included in the APN Type or MMS Messaging will NOT work. Just for future proofing Make sure you APN Protocol is set to IPv4/IPv6 as set with the latest LTE phones.
Once done select OK and then Save at the bottom. Once done make sure to Select the APN Radio button you just edited a couple of times. You may see your Data connection go out and then show 3G/H/H+. This is normal as it is refreshing settings. Let your phone sit up 5 minutes or until 4G Shows up. Once it shows up, hop into the Messaging app and try sending a MMS message to yourself and you should be able to send and receive it without wifi over 4G LTE.
Those on AT&T, the same fix applies, but with your specific Carriers's APN Settings
Just to let you guys know and other friends, if you ever get on a AWS band (3G/H/H+) and you have NO data connection and your carrier is T-Mobile, this is because T-Mobile has shut down (Or will be shutting down and removing) all AWS band antennas from their towers to make room for new Cat. 6 Carrier Aggregation. So if you get the MT7-L10 version (which is the 3GB RAM Non-LTE version) the AWS bands probably won't work with it and you are stuck with using 2G EDGE as data. This goes for ANY phone that relies on one of Many AWS bands to get 4G Speed internet. For more info on this, check out http://www.tmonews.com/2015/06/aws-hspa-t-mobile-markets-shutdown-dates/
