T-Mobile network disconnection - G1 Android Development

Hi all,
First time poster, long time lurker I'd just like to say thanks to everyone in the community. You guys rock.
That said, I am having a minor issue with my G1. I have T-Mobile & my phone is SIM unlocked (I don't know if that would make a difference) and currently running JFv1.5 with the latest radio (2.22.19.26I). The problem is that when I disconnect from a wireless network, my data connection to T-Mobile doesn't pick back up. When I go into Call Settings / Network Operators I let it search for networks and sometimes my phone will have to Re-Register on T-Mobile and other times it will say that its already registered to T-Mobile but the data connection still won't work. The only thing I've found to solve that is a reboot of the phone.
This has happened a few random times when I was on RC33 and one of the Haykuro builds but it has become more frequent since I've updated to JFv1.5. Also, I dunno if it helps to mention but I went to a T-Mobile store earlier this week & swapped out the SIM card with a new one and have gotten the same results.
Is anyone else having this problem? I've searched to no avail and was curious. Thanks.

dissconnect
That's just typical crappy T Mobile service have the same prob here since I'm not close to a T Mobile tower when it loses web access it dumps the connection to reconnect

So that's it? I should chock this up to my carrier's signal being ****ty in random places? No one else has had this issue at all?

I am having this issue. Never had a problem until I updated the radio to the latest version

I have had the new radio since the JF build with cupcake. My signal was great until yesterday. It will go from the lowest to highest in the case of the bar. When I reboot my phone it takes much longer to connect to the network. BUT I think my issue is with the fact my market (Columbus, Ohio) was rumored to get 3G by this june. So I am guessing its just TMobile doing the upgrades and whatever they need to do to impliment the 3G rollout.

lately ive been having horrible service. dont know if it has to do with the new LX being released.

Hi,
I am on 5.02h and was having random disconnects on .26 radio.
I went back to .22 saffaire radio and my connection is more stable now.
I am not sure if others have experienced this as well.

I have flashed my phone yesterday with latest from Haykuro with CUPCAKE. (NO SD APPS)
Phone is running a little slower and I started having the issues with the DATA connection.
In the middle of the Web page loading, the phone looses data connection and I am only left with ability to use voice. The data connection comes back in a few minutes and same thing happens as soon as start using the data connection again.
I do not know if previously stable connection at my location all of a sudden became bad or the new build is causing this.......

just to add
Not to dissenlighten people here but t mob has crappy serivce to rural areas. I myself live in brunswick md usa. I have had. 2 bars since I first got this phone with rc30 with constant dumps to no signal all the time when it upgraded to rc33 still the same thing. Then I rooted my to jf rc33 still the same thing. After that I used jf 1.5 and it still craps out. When I go 20 mins to the north to frederick,md I get full bars and no dissconnects so if it where a radio issue there would have been some kinda difference between radio updates. I myself am a ham operator so I should know how radio signal works so when I chock it up to t mobs crappy service I do not do this lightly since the nearest tower is 20 mins either way from me. People need to stop blaming other peoples builds for this issue since the radio update is from google. If I pop a att sim I get full bar and no dissconnects cause the tower they use is closer that's how I know it's a t mob problem not an issue with the radio. Remember troubleshooting is the best way to see where the problem is. Till t mob puts up more towers and fixxes the packet loss to the phone to remedey this then we will all have crappy service which does not seem to be in the near future for anyone.

I had a similar problem when I was on stock RC30. I called in to tech support and they set up a new APN on the phone so it would switch back to EDGE faster if I lose the wifi connection. I would suggest if you're not around stable wifi, just turn it off.

Edge problem

I'm currently using JF's rc33 1.41 and my connection to the edge network just isn't showing up anymore. Is this a reoccuring issue because I cannot find anything of the sort on a search? Thanks for your help.
i hope it's just tmobiles network down. i just experienced no edge connectivity for a while on rc33 lite so i wiped and loaded up the basic rc29 hoping it wasnt just the jf version that was messing up the network. seems like the stock firmware also has a bit of difficulty connecting to a network right now. i was at the sign in screen forever then i looked back and there was edge. now its gone again. just my 2 cents though
I put my sim in an old phone and the edge came up just fine.
Anyone install or upgrade new apps?
I even tried re-installing the newer radio version.
My 3G is down also... not just my edge. I literally have no data connection unless WiFI.
You're right, it just seems to be a network problem because I just got re-connected.

T-Mobile Network Outage
I just got off the phone with Tier 3 tech support and he said that they are experience a network outage in markets west of the Mississippi. No ETA.
Network down here in los angeles also
T-Mobile Network Outage
As of 10pm PST T-Mobile started experiencing a data network outage.
Some markets were effected at different times but the Tier 3 tech support in New Mexico has been flooded with calls about no data connections with the G1 phones. According to the representative in Tier 3 tech support this is effecting all 3G equipment and there is no ETA on the repair.
Phone calls and text messages should work just fine.
If you still have no data connection in a few hours then try calling tech support (800) 937-8997.
Do NOT wipe, reflash or anything else until after you call to confirm that the problem has been resolved.
Thanks.

Widget turned off 4g/3g, can't turn it back from 1x

So I was playing around trying to delete widgets and one of them took out my 4g/3g connection. The icon is stuck in 1x, and I can't find any setting to change it back.
dail *#*#4636#*#* . This will take you to the network settings. select phone information. And then scroll down to set preferred network type.
I did that, set it to both LTE mode as well as CDMA+LTE/Evdo, but then even when rebooting to toggle it, it shows Network Type as CDMA - 1xRTT
I'm seeing other threads with people having issues with being stuck in 1x, so maybe its just not me, and I disconnected and just happened to not get it back
I am having this issue as well. Rooted last night. In the process of removing system apps removed something I shouldnt have. Went to flash my back up created by Rom Man only to find out it wasnt made, fail, so i flashed the custom rom by Chingy. Since flashing the rom I only have 1X service no matter what I set the phone to on the toggle.
its not just you bro ive been having 3g and 4g problems all morning. I am in queens NY...if they dont get this fix before the 14 days I am returning this phone and going back to t-mobile
I had thus problem. Just turn airplane mode on for a minute, then turn it off and you should get 3g again.

I'm not even rooted, and I began experiencing this issue this morning after having my phone off and plugged in last night.
EDIT: I tested the above fix, and it didn't work for me. Every time the phone tries to turn 3g on it will appear in the status bar for a split second and then everything turns off, even 1x. weird.
It's a network problem on verizon's end. I'm in Cincinnati and data is not working at all.
I am getting this too - according to tech support, there is a problem with the 4G network right now - however why it doesn't fall back to 3G I don't know (unless there is a problem with that too).
I too am in New York, so it might be localized to NYC - They even tried resetting something on my VZ profile.
I'm still on the call as we speak, but I get the feeling given the number of people reporting this, it is a VZ problem.

It's definitely not just a localized problem. I'm all the way out in Utah (no 4g service here yet) and the 3g is completely jacked.
Yup confirmed with tech support, there's a nationwide outage with 4g data and they are working it with the highest priority, the tech said. Ah the costs of new technology. Always will have issues at start.
Same thing here, Pensacola, FL. Just went out on my drive to work today, now it's 1x across the board for me and the gf...she has an incredible and I have the tbolt...
Add me to the list. Been on the phone with tech support for 52 minutes and counting. I'm on hold right now and thought I would check xda. Stuck in 1x if I even have anything. I am about 35 miles south of Pittsburgh, PA. Phone is completely stock and worked perfect yesterday. Also, the tech said DO NOT dial *228 from the Thunderbolt. I didn't, but he said for future referece it will force the phone to use only 1x and 3g. Nice to know lol they didn't say that crap when I bought it. At least their tech support guys are super friendly.
Weird. Im in Akron Ohio and have full bars 4G. Just did speed test and getting 15Mbps down 20 up. Downloaded app off market just to be sure and downloaded without a hitch. This must not be affecting whole nation. (Yes my Wi-Fi is off lol)
Just got off the phone with VZ Tech support. He said there is not an acknowledge problem with the 3G network right now (unlike the 4G), but he's sure that soon there probably will be.
He could not use my phone as an example case (to raise the trouble ticket) because I was unwilling to perform the last step in the troubleshooting process (reflashing the phone) - but I'm sure there will be others willing to do that and this will become a known issue soon enough.
Worst part is, even my 1X support keeps going in and out - probably because the 1X network in NYC is overloaded, because all those users usually on 3G are all on 1X now, and killing it
Confirmed here, too...all 1x, must be a nationwide 3g issue
Same here south of Chicago. Guess I won't even bother calling about it. Thanks for the info.
This is definitely a widespread issue... I am in Miami and I can't even gey 3G here... I am only getting 1X.. The weird thing is, my friend has a Thunderbolt too and she seems to ne getting 3G fine.... If anyone receives any worse from Verizon, please post ASAP!!!
Yup im located in Manhattan New York having the same exact problem since 8:30am today No 4G or 3G i hope they get it fixed Soon Let's Go Verizon!

[Q] mobile data not working, poor or no phone signal

Hey guys, I haven't done anything to my phone but all of the sudden, the data and phone signal basically quit working. I have a very hard time getting texts, phone calls etc to go though but it will eventually (usually takes a while or a few tries) and as far as data goes, I basically have no connectivity at all unless I'm on wifi. It says 3g or H every once in a while, but it's really slow and usually doesn't stay for long. I'm running CM9, and like I said before I didn't change anything that I'm aware of that would have caused this problem. It worked fine before, and it just stopped. Ideas? Thanks

have you called your provider? maybe its on their end.
I'm having the same exact problem... it shows my 3g it shows all my bars but instead of the bars being colored or the 3g be in color is gray. Also I cannot get back conectivity until I restart the phone. Does anybody have an idea what this is?
Are you on AT&T? I was not having any problems until a certain point in time, and I didn't change or do anything to incite them. I'm not even getting calls anymore, I'll just get all my texts in a wave every few hours. My data is useless, it won't stream, or load web pages, and my phone is frequently saying "Emergency calls only" when I'm sitting at my freaking house (which normally has full 3g and cell signal and is very fast)
This just started occuring with my 9020a on AT&T the first week of March. I switched SIM cards twice, spent about an hour on the phone with ATT, and sent the device back to Samsung who rolled back the software to 2.3.4 and the Radio to UKE1.
I still have the issue. Samsung says its not them. ATT does nothing. It;s liek the phone just stopped working, started dropped calls, missing calls, and the internet connection sucks. I have an iphone for work through ATT as well and have no issues with signal.
ANy help is appreciated.
Hmm
Make sure you have the right, most up to date settings for APN, and flash original radios. if it still doesn't work, make sure you have the i9020A, which has the at&t 3g antenna, not i9020T which has the T-Mobile antenna, vice versa.
Have you tried other radios for your device (make sure you flash the appropriate ones for your model)? Any signal info under Phone Information when dialing *#*#4636#*#*?

Sounds like you're having the exact same problem I am having. I switched sim cards, flashed different roms, etc and nothing. (although to be fair, after the new sim, things work better, but still not well) I'm about ready to pop my sim back in my craptivate and just go with that... or buy an iphone off of craigslist.

I am 100% sure I have the 9020a, but I don't know anything about APN and flashing radios. I have only ever flashed full roms before, so I wouldn't know where to look for the original radio.

I have not tried other radios. The signal info seems solid, sitting at my house, but the 3g is still horridly slow. It taked 15-30 seconds to load a webpage, even a pretty mundane one like google. Messages still come through in waves, and often won't send
About your APN, AT&T should provide you with the proper values to put in under Settings | Wireless & Network | More | Mobile Networks | Access Points Names.
If you are on ICS, they values should populate by themselves.
Can you try flashing other radios and see if you encounter the same problem:

Make sure you backup your EFS folder (and all data for that matter).
I had similar problems, they were related to turning 3g on/off with a APN widget while the phone had little signal. As soon as started enabling and disabling 3g on the android options everything was back normal.

the data works most of the time now it's just retardedly slow. I can't stream music even on low quality, nor can I watch youtube without leaving it for 5 minutes to buffer,pages take forever to load, and I was downloading a 6 meg app and it took 20 minutes to download whenI was leaving the phone alone and not moving. I got really sick of trying to fix it and finally gave it to geeksquad to send in to get replaced. sigh.

[Q] Cellular phone connection dead from one minute to the next

So...
I am running my phone rooted, but mostly stock (just some removals) with ROM 1.53.401.2 and he 0.15.3150S.19_10.31501S.06L baseband.
Its been perfoming fine ever since so I never bothered to upgrade to a custom ROM or the newer basebands.
Its an EU unbranded phone. As of tonight, with nothing special done to it it seems to have lost all cell reception. All I get is An x where the 5 bars are. Funnily, when I turn of my WiFi router and select wireless internet, I can get online and download data through the cellular inetnet connection. But not a single call or SMS will go out.
I have moved to like every location in my apartmant and outside and nowhere I can even get a single bar of reception or even a call through.
Does anyone have any idea WTH this could be, what could have caused it? Any ideas on where to prod and poke for a solution?
Mine did that for the first day after I put a non-stock ROM on it...hasn't done it since. I took the piece that covers the SIM card off and popped it back on. I don't know what causes it though.

[Q] 4g data drops often...too often

i have to reboot in order for the 4g data to work again but it only stays on for about a minute and then it stops working again. everything else on the phone works ( text, voice, wifi etc...) I read somewhere that flashing different radios might fix it but im not sure about that. anyone else experience this and have a work around? i am currently on baseband i535VRLG1
Thanks In advance
i called Verizon and they said it may be the sim card thats damaged. if that were the case wouldnt voice and text fail as well?

I'm having the same issues recently. I've always gotten a 4G signal at my house (albeit not the strongest one) but lately, my phone will not hold on to the connection. When coming off of wifi, my phone will not acquire a data connection at all most of the time. I can still send/receive texts and calls but there is no 4G or 3G icon, no MMS, and no data. I have to toggle the radios on/off, or change from CDMA/LTE to Global (or GSM) and back, put in airplane mode, or restart.....there is no guarantee any one of those steps will work. Sometimes I have to do it repeatedly until I get my data connection back but it is only temporary.
I'm on the i535VRBMF1 baseband and updated to the ML1 modem to try and resolve but to no avail. I have replaced my sim card (as I initially though that was the issue) but it has not helped either.
The only thing I can think of is that my PRL may have been updated (it is currently 15310) and it's causing issues with the towers in my area.
I just got back from Hawaii and was also in San Diego for a few days and had absolutely no issues. It seems to only be an issue now when I'm at my house which makes me think it is something VZW network related and nothing to do with my phone per say. It's really driving me nuts though.
BTW, I'm in Southern California (Irvine).
I seemed to have fixed the issue by reverting the baseband back to vrlf2. I had to switch from global to 4g/LTE because I vegan to inch roaming charges lol. Verizon credited me and no dropped 4g signal. So I'm happy.

What ROM are you running? I'm just curious what the implications are of running an older baseband (from the ICS days) on a newer ROM/Kernel.
I'm running cleanrom8.1 core edition. Slightly buggy but tolerable.
I was finally able to somewhat resolve my issue so I thought I'd post in case anyone else is experiencing something similar.
By using a few different apps and testing techniques, I was finally able to deduce that my issue had to do with EHRDP hand-off with the towers in the immediate vinicity to my house. I'm not sure what VZW did to them lately but it doesn't appear to be a problem in other locations so it seems like the issue is on their end (and not something to do with my phone).
In any case, it seems that when my 4G connection is weak and EHRDP is detected, it is dropping the connection entirely instead of handing if off to 3G (EVDO). The connection is also never transferred back when a 4G signal is detected either until I reset the connection where there is a moderate 4G signal.
Again, this only seems to be an issue when connected to the towers near my house and doesn't occur when traveling abroad.
To fix this, I have disabled EHRDP by doing the following:
1) Open the dialer and type *#97328640#
2) Select "[2] CDMA"
3) Select "[2] Data"
4) Select "[7] eHRPD e/disable"
5) Select "[2] Disable(*)"
6) Reboot the phone
Now my phone switches between EVDO revA. for 3G (using the native protocols) and LTE rather than relying on the broken eHRDP protocols. This workaround will have to suffice until VZW fixes stuff in my area but at least I don't miss MMS messages anymore.
Hope this helps anyone running into similar situations.
