3G Connection Issues on CM 4.2.7.1

I am having a very strange issue:
Whenever I am at home, and my G1 is connected via 3G, I cannot use data or make/recieve calls. If I enable the "Use only 2g networks" checkbox, it reconnects via EDGE and works perfectly. I currently have a service request out with TMO which should resolve in the next 24-48 hours, but I was wondering if anyone had heard of this issue.
TMo has no idea why I'm not getting signal, the problem continued even when I reverted to stock "Cupcake".
Things I've tried:
Reverted to stock firmware and unrooted phone (Didn't work; same symptoms)
Call T-Mobile, they removed and re-added me to network. (Didn't work; same symptoms)
Swapped SIM card at T-Mobile store (Didn't work; same symptoms)
T-Mobile service request in my area (Results pending)
Things I am going to try, but haven't yet:
- Return to stock firmware, reinstall CM 4.2.7.1
- Try an older CM like 4.2.4 or 4.2.5
- Connect to WiFi for data connection, see if this replicates the problem as with 3G
- Enable data roaming.
The fact that it only happens at home leads me to believe it's not a problem with the phone, however I'm more than willing to do more to rule it out.
Phone Specs
T-Mobile G1
Firmware Version 1.6
Baseband Version 62.50S.20.17H_2.22.19.26I
Kernel Version 2.6.29.6-cm42 [email protected]
Mod Version CyanogenMod 4.2.7.1
Build Number DRC83

Dont tell T-Mo that your rooted thats a big mistake right there, that can be used against you if you ever have to get the phone replaced.Play around with the apn settings and make sure "always on 2G" isnt checked in settings. Maybe your house isnt in the small 3G coverage area, or your phone cant connect to it. Why would you think data and talking at the same time would be possible? Its either you answer or you stop browsing the web.

Yes, thank you, I know not to tell them that, they have zero idea. I also forgot to mention they did swap out my SIM card at the store.
Read what I posted. Turning on "Always On 2G" is the ONLY WAY I can make calls and use data at home. When that isn't on, the phone says it has a 3g connection with four bars, but will not dial out, take calls, or connect to web pages. I've also verified my APN as epc.tmobile.com which is correct, and this affects my voice and data communications.

Try another rom to confirm you cant get 3G, it could also be HW failure.But just try a older cyanogen or something else.Ive cant get a 3G signal with cyanogen roms for long but with a hero rom i seem to get 3G(maybe its my imagination)

It fails on both stock (untouched, unrooted), and CM. I'll try an older CM just in case though.

Rebooted phone between each of these tests:
3G With WiFi enabled: Same result, can't dial out.
Data roaming enabled, Wifi Disabled: No signal at all, 0 bars with "X" symbol.
Stock firmware: 3G won't dial out, forcing 2G works.
Downgraded to CM 4.2.4: Same symptoms.

What ! if you have 3G coverage you can talk and access data at the same time.
That is what 3G provides.

That's not what I'm trying to do! When I am at home, on a 3G connection, I cannot do ANYTHING. That includes text, voice, data, web, ANYTHING. If i force it to use Edge, all services work properly. This is not acceptable. T-Mobile's coverage map lists me as in a strong 3G area. It SHOULD work.

I dont know what to say, except stay on edge, you alreadt sent a req to tmo.

I am having the exact same problem. Would love to learn what you found out.

Want G1 no Data Plan-What will it take?

I have had a G1 with Tmobile for 6 months or so. The price for used G1's have dropped alot on ebay and my son is thinking about buying one as a cheaper alternative to an iPod touch. At a minimum, he wants to play music, video and install apps. Ideally, it would be great if we could get it to work on TMobile without a data plan. Here are some questions that if anyone has answers I would appreciate:
1. Could the G1 simply be used as a mp3/video/gps device without a voice or data problem?
2. It looks like the G1 can work on TMobile without the data plan (despite TMobile's official word), but what does it take to do so?
3. If #1 and/or #2 are possible, will a rooted phone be required?

i have a g1 without data myself. everything works fine except you cannot send picture messages. you can still browse the market and the internet as long you are connected to wifi

If you don't care about the always available marketplace, google services, browsers or google maps then go for it.
The only issue is when trying to activate the phone, but for this just borrow someones Data Activated sim card.

Thanks for the replies.
1. So, do the google services for gmail and maps still work with a wifi connection or do they not work at all?
2. If we root this thing, then it looks like whenever we do a wipe we will need to have an active sim card ready. Is this correct?
3. Do the OTA updates only come through the data plan? I assume so.
4. Once you activated the phone with the active sim card how did you get a sim card with voice only to work with it. Did you pull it from another phone?
Sorry for the questions, I have rooted by phone, but am a bit of a noob when it comes to sim cards.
Thanks.

1. Yes, you can do everything over wifi.
2. Not always. The newer roms (since 1.5+ I think) lets you skip over activation when you first start up. You can then set up your wifi connection and later sign into your gmail account by launching any google app. Not sure if this is in the official 1.6 version but it is in any modded one.
If not you could always try launching "am start -a android.intent.action.MAIN -n com.android.settings/.Settings" through adb if development is enabled by default.
3. No OTA updates work over wifi too.
4. Not sure. I guess just pop in the voice only sim card and delete the APN so it wont automatically sign in.

If your buying the phone new it should come with a non activated sim card used to just start the phone up at least and not have it ask for a network. I did this with my Behold II and I'm still running it through my wifi as a mp3/app phone. I wouldn't see why the G1 would be any different.

I have a G1 on AT&T without a data plan.
The thing is that my G1 tries to connect to edge (2g) services when I initially set it up. This can easily be disabled in settings (in some roms) or you can modify the apn so that data won't go through, but SMS and calls will. Although I can connect to edge data whenever, I am charged for it as if I were sending MMS messages.
Seeing as you are on Tmobile, when you initially try to set it up, I'm guessing it will connect to a 3g network (that is if your plan is like mine and you have the capability to access 3g, but just don't because of the price). If you have no 3g or edge services at all, then you won't connect and you will have to get around the registration process another way. (I.E. Installing adb and opening the settings window on the phone through the computer to activate WiFi, or somehow getting to a rom which lets you bypass the activation process)
Good luck!

I have a G1 without a dataplan. I get full HSPA service and 2mbps web browsing (all data works) with my $20 dollar unlimited fun bundle intended for dumb phones.
I got lucky

Thanks again for the feedback. This is looking better and better. However, I still don't understand how you get voice plan to work in the first place.
1. Will I have to sign up for a voice/data plan with TMobile and then drop the data plan or is there another way?
2. Are sim cards 100% interchangeable?, i.e. if we have some other voice only phone on TMobile and remove its sim card and place it in the G1 will the voice then work on the G1?

It might be best to just get one that is not wiped, and use it without a sim. I have one without a sim right here (extra) and it works fine over wifi. However once you wipe it there is not a fix that doesn't require rc29, I think. You can also use any simcard with it. When you remove the simcard and put it in another phone, the new phone gets all of the plans that were connected to that sim card

I was hoping to get voice to work on the phone. To do this I thought you did not have to downgrade/root. From what others have said, if the phone is wiped, you can need to insert a sim card with a data plan then activate the phone. From what others have said and I have read I think I can make this work by doing the following:
1. wipe phone new g1 phone
2. Take the sim card out of my "current g1" with a data plan and put it in the "new g1"
3. Turn on "new g1" and register/activate it
4. Remove sim card our of "new g1" and put it back into my "current g1" phone (the one with data plan)
5. Put TMobile sim card without data plan into "new g1".
Am I missing something, or should the above work?

That should do it.

Since T-Mobile has now gone and added a ton of no contract plans. I would just go and sign up for one and say you already have a phone and just need the sim card. If your adding him onto a family plan then get one of the free phones and sell it for $10 and keep the sim card. No reason to even suggest adding a data plan.

jfrankman: That looks good. Just make sure you go into your apn setting and delete them or it will automatically connect and start charging you.

"Just make sure you go into your apn setting and delete them or it will automatically connect and start charging you"
Change what in the apn settings? What will they start charging me for?

Just delete them, or T-Mo will charge you for using data

Forget running T-Zones on the G1.. its a lost cause trying to get past the big T and get everything working at 100%

is it possible to disable data connection completely?

Hi,
I had a diamond cdma without any data plan, and I don't need any data plan, however, the Bell charge me a lot for the data connection, even I disable/delete the connection, change the dial number (#777), when I use the wifi, I still get some data charge.
Is it possible to use a rom to disable the data connection?
Thanks.

you can do it manually....ok first go to settings, then connections, then connections ,under my isp go to the third option and in that tab you should be able to delete the settings...after deleting it return to my isp and touch where it says manage(or the second option to be exact) and where it says #777 just touch the number and leave your finger there until you see options and choose delete.....

it's easy but not working ...
thank you,anyway.

i have my own roms (chek in my signature for the link,if u want to) and they have no settings for data....if not just go to ppcgeeks and download the phoenix rom and theres and app in there to disable data

thanks,after I pay $50, BELL finally agree to disable internet connection from their side .
if I said Bell is the worst mobile carrier, most people won't agree, most people always think their mobile carrier is the worst. -

actually, I called the customer service when I got the phone, they told can't do that technically, and I called again, they told me to delete all the related number.
untill yesterday, I have to pay $50 for the data usage, they agree to disable the internet connection from their side.

I'd use Modaco NoData for that...

Going to Europe. How to disable data connection and enable wifi only?

I'm going to Germany for a month and do not want to accrue any voice/data charges while I'm there. I plan to use wifi only. What's the best way to disable voice/data, but still use wifi? I also want to make sure that my apps do not try to establish a data connection outside of wifi. One idea I have is to keep the phone in "airplane" mode. But I'm concerned that if I reboot my phone it will kick itself out of airplane mode and start roaming.
Any suggestions?

change the APN settings to point to a non-exsistant server, cell interent wont work but wifi can be on and you can still make/receive calls and SMS if need be

I just got back from Europe, this worked wonders for me.
1. Go to Settings
2. Go to Wireless and Network Settings
3. Go to Mobile Networks
4. Uncheck the Data Roaming Option.
This will prevent your phone from using data while you are roaming.
@dcplaya I am also running on Cin Bell. Works great!

Or get a German SIM, that way you'll have data. If anybody calls you on your US number let them leave a voice mail on Google voice

I have a Nexus One in the UK and have so far taken it to the US, Switzerland, France, NZ and HK. The above definitely works and should be all you need to do. I just had a look at my online balance and can confirm the total on my data charges is £0.00. Note that you can leave this setting disabled the whole time, even when you're in your own country. The phone distinguishes between roaming and non-roaming and acts accordingly.

awesome thx - i came to post this exact question and bam, first thread.

Can I Do This?

Goto T-mobile website and change the phone on my account from G1 to another and buy a text messaging plan under that? would it work with my G1?
right now I have NO text plan or data plan, and tmobile does not let you do anything unless you buy their android data plan.

No you can't....For data you must be using the android data (25bones), I tried a BB's sim to test(Talk/Text only) it worked fine. The apns might only work for the tmo G1 plan though.

My little sister uses a cliq with a $15 prepaid unlimited texting plan so I don't see why not. You will need to put your sim card in a dumbphone, then call t-mobile and ask for a messaging plan. also, make sure to download APNDroid from the market to disable data.

Since they'd need to check the IMEI of the dumb-phone, probably.

As for data if you have a Wi-Fi connection you can use that as long as you have a data "capable" SIM. I personally have an old H6315 from T-mo and it had to have a data compatible SIM card in order for me to use the phone. I am currently using that same card now except that I cannot use data (except Wi-Fi from home) and I send & get texts all the time (pre-paid prices). However the downside of this is if they know you have a G1 you most likely have a G1 specific SIM card in it and there is no way to do that unless you get a new SIM card (go to a T-Mobile store) and then after they see the phone they will give you a bunch of hogwash about "You must have a G1 SIM card."
If you have an older style smartphone around get it out and go buy a new SIM with it. If you only have the G1 all I can say is "good luck"!
I have personally done this in my own "stock" G1 and it works flawless. You can keep the data (2/3G) active and everything will be fine. You just can't browse anywhere. T-mo will send you to a site (over edge) for you to upgrade your services for data. But this is all on a pre-paid SIM that I am currently running that I got a long time ago for an older XDA type smartphone in 2004. I am not sure if you can even get the prepaid "dummy" SIM's anymore. But they still have pre-paid so I can't see why not!
