T-Mobile network disconnection

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.

[Q] mobile network disconnects and gets stuck "turning on"

Hello all, i have had my HTC sensation 4G (on Bell) for just over a month and a few days ago i started losing my connection to the network intermittently. Super annoying. Anyways i tried deleting some recent apps, figured that might be the issue but nope didnt help. It happened about 3 days in a row until i finally did a Factory Reset on the phone. It worked fine for a bit and then began stopping its connection to the network. Anyways super frustrating, i read some forums about tunring ciphering on and off, i tried that didnt work... needless to say im chapped.
Sorry for the length, but basically wondering if anyone knows how to fix this as its to late to return the phone and i have read through similiar forums on other phones

sorry to hear abt ur problem. i experienced the same thing but i think mine was triggered when i installed juice defender. it would turn off mobile data when the screen was off and when i went to use the phone, i didn't have a connection. i uninstalled the app and did a power cycle and that seemed to fix the problem after i went back into settings and checked the box to turn mobile data on.

This. The phone seems to have trouble (on the stock kernel at least) when switching data from wifi only to cell when cell is turned off. This happens to me when I use wifi calling. The solution I came up with was to connect to a wifi network then turn on mobile data in the quick settings manually. Works every time for me.
HTC really needs to fix this.

Under mobile network in wireless settings, enable always-on mobile data.
This somehow fix my connection whereby it hampers with JD app by not turning on when it needs to.

Thanks for the help guys. I did also recently install a "battery optimizer: in Droid Utilities or soemthing like that, although i did a factory reset. ill try and do a full battery cycle like you mentioned and see if that helps

so the phone worked fine on the weekend, and even friday and i thought it was cause i stopped using a non "htc" charger and got rid of Android Utilities. but now its Tuesday again and like clockwork at 1pm it just stops connecting, if i reset it i get network for a few minutes and then boom out again. Very frustrating mid work day to be without my phone for hours on end. Dont know what to do.

Are you using WiFi at the time it goes out?

No i havent been, not allowed to use private phones on the corporate wireless, but so far i havent found a problem with it switching between wi-fi and H+ while at home.
I have a feeling that Bell Canada may be updating the network or something in the area but they havent said anything both times i called and i asked. so who knows. Its just to much like clockwork for me to think it would be the phone, but who knows.

So i believe i have this figured. I talked to tech support once again yesterday and i point blank asked if it was network problems he said no (3rd person from bell to tell me this) then reccomended i get a sim card change if that didnt work he said send the phone in for repair.
So i went to the downtown bell store talked to the girl, explained why i needed to replace a brand new sim, and she told me that it was because Bell doesnt have towers downtown they share the Telus towers, however because of network bottleneck bell users get less priority and thus i cant use my phone... Not only is this unnacceptable for a phone company to not provide service DOWNTOWN in a major city but having denied it multiple times forcing me to troubleshoot for hours and spend almost an hour talking to bell representatives...
NOT HAPPY. Bell - 5 in my books, lucky my contract is up in a few months and i can switch to telus where i will be able to get signal downtown...

no 2g to 3g?

As the subject says recently when i turn off 3g to use edge and then go to turn back it wont let me
The only way i can get back to 3g is to turn data off and on manually by hitting airplane mode
Any suggestions?
Thanks

no one else has this issue?

I have the same issue it takes a long time to get 3g, I'm with vodafone au so the network is horrible. This might be the issue that the phone can get the troubled network.

I have this issue. Only fix I've found is airplane mode/battery pull.
However, if the phone automatically switches down to edge (2g), it will usually switch back on its own.
Don't even get me started on the frequent complete data shut-downs though, and that's with what little there is of the signal present. Completely ruined Google Voice functionality.

Well IM on ATT in the northeast US. I upgraded my radio from XX to UCK and I think it solved the issue for the most. A lot of outages here tho after our storm (apparently only on ATT tho as USUAL since verizon and sprint seem to be fine. ATT blows!

[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.

[verizon] Banned from my home tower.

So I've been on Verizon prepaid for at least a year. Last Thursday (night) 3g stopped connecting and the phone drained the battery down a bit. I switch to 1x and internet works. I thought it was a problem with my service but as soon as I leave the area I can switch to 3g and connect just fine. As soon as I come home its back to no internet or 1x service.
Calling support was no help and they can't figure out what's wrong. They keep trying to blame the phone but I switch phones and behavior is the same. Only difference they can see is that my current imei isn't the same as what I registered with. I can go switch that back but I get the feeling it won't help. I have to reflash the stock rom to see network messages or change back so I'll do that on the weekend just to be sure.
Anyone work with the network and can shed some light on this? Anyone one ever been banned off one tower only?
