All, I am sure there is a thread on this somewhere, I just can't find it... please help.
I've got an AT&T Tilt with stock ROM, no bloatware. The problem is that when a phone call comes in (or I dial out), it seems to drop or interrupt the data connection even on 3G. Very annoying.
On my 8525 with WM6 ROM, this never happened. I could be connected to the internet (typically connecting my laptop via Internet Sharing on the 8525), and be talking on the phone at the same time -- the data connection was never interrupted. Of course if I was on an EDGE or GPRS network, it would -- but that's to be expected since GPRS/EDGE use the same radio as GSM. On the 8925, as I stated above, a phone call interrupts data even on 3G!
Has anyone seen this? How do I fix it? Thanks.

Yep overhere also... testing all radio roms but all the same... so far no fix found... we have to live with it...
The kaizer is dead... long live the Kaizer...
... to many problems
I'm in Edge country right now, but will be in 3g in a few minutes as I'm getting ready to roll out to LA, I'll email you from the car to test if the 3g and phone call can co-exist.
I think it has to do something with AT&T's cell towers. I also experienced the same issue that when calls came in my data connection would be cancelled. However one day, out of the blue, the 3G icon was suddenly replaced by an H icon. And it is there all the time! Now I can call and download data at the same time.
Thanks... that's bizzare. H means it's using the HSDPA protocol for 3G, U means it's UMTS, I think now the 3G icon shows up instead of U. (I hope I got my acronyms right). But that shouldn't matter! My phone will go between 3G and H, I think based on the capabilities of the towers. There is no telling what will show up in a given spot.
The mystery remains... Come on, all experts out there, share your wisdom. Could this have anything to do with disconnection settings or TCP settings (done via KaiserTweak)?
I think I just found the answer. Went to KaiserTweak, and selected the Data/Disconnect After setting, which I had set to 1 minute. In the description for that setting, It says "warning.." but you can't see the warning unless you go to landscape mode, which is why I never noticed it before. The warning says that with this setting, 3G Simultaneous Voice and Data will no longer work.
Disconect disabled, and a quick test showed that the problem is solved.
hello all, this is my first post here.
I do NOT have a data connection package on this phone (i don't know if this effects it or not), but whenever i go into a 3G area my phone loses signal and gets none whatsoever. I only get signal where there is an Edge connection. I purchased this phone used so there is no warranty or anything. Ive taken it to [email protected] and they say that the only thing i can do is buy a new phone , but i love my phone. Is there anything i can do to fix this?
Flash a different ROM. My roms in the sig are TILT roms and will work in 3G and HSPA using ATT in Houston. Just make sure you get the connection settings right. The problem with your connection cutting out has to do with a combo of the ROM and the radio.
what are the right connection settings? and do i need a new radio? which radio would work?

Go here. And read the Guides section for the radio and how to flash, most roms require you flash the stock one on there first so go to HTC->support>choose your product->download the latest rom image, it should be like 119mb or bigger. For the settings, do a search on here for ATT connection cab. it will set up the connection without you doing anything. if you can't find it I'll see if my friend can post it somewhere.
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

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.
I had CM 6.0 installed and everything was working great until a couple days ago. My phone would periodically have no service and I cannot send texts, make calls or have data. The 3G symbol shows upload and then the H symbol shows upload, but then no download bar. This problem got worse as the time went on. I also had the latest nightly installed but no luck.
I decided to wipe everything and revert back to stock. Everything was flashed back to stock, including recovery, the newest radio, etc. But my phone still doesn't work. When I turn on the phone, it just shows no service or no 3G symbol. However, when I put my roommates AT&T sim card in, it works on edge.
I am on T-Mobile, and it is really frustrating. So right now I have to use my old flip phone.
So is it my radio's problem or sim card?
hey same here my brother aswell
are you on the 2.2.1 update? I am having the same exact problem. I'm running stock rom, 2.2.1. This started 2 days ago for me. However when i switch my phone to 2G only under settings > network my phone works. I am using the 5.99 tzone are you? I am curious to see if this issue is only for 5.99 tzone 3G leechers or all users of the nexus one. a guy in seattle i spoke to has the same issue. so does my brother who also has the 5.99 tzone.
yea, im on the new 2.2.1 update too. but i have the unlimited data plan.
so i did some more testing with my friends samsung vibrant with my sim card, everything worked great. got like 2mb down.
i used his sim card in my phone, and same problem. it only shows upload and no download. but i was able to send and receive texts and make calls, but no data.
yea something is wrong for sure man just called my buddy and he has unlimited data and 3g is not working at all
internet2.voicestream.com works fine put it in apn in settings
that worked for me, but still only on 2G.
every time im on 3G, its so sporadic. and not reliable at all
is it possible for the radio hardware to die over time?
I noticed if I go to the mobile networking settings and have it it on lte/3g if I leave a 4g area, 3g works ok. If I put the toggle specifically on 3g it shows I have 3g, but anytime I tried to search google or access a data connection the signal goes away and gives me the signal with an exclamation point. I tried finding info on this, but didn't see anything when I searched. Anyone else have this issue? I am on Sprint with the 64gb white device. Thanks
I leave mine on 3g due to the lame multiple text issue. It has no problem staying on 3g. Perhaps try updating your PRL/profile and see if that helps.
I don't have 3g either if I set it to 3g only. I don't leave lte service too often to test whether 3g works when it switches on its own. I may have to make a trip to the mountains to test it. I do know that my old Note 2 would loose lte after flashing tons over and over and I would have to flash back to 100% stock the factory reset from the settings app to fix it. I may try this with my Nexus, about time for a wipe anyway.
Factory reset does not fix it. Just noticed that I don't even get 3g when it is set on LTE. I'm gonna go talk to my cellular provider about it.
I don't know why it wouldn't work. You did update profile and PRL also right? Here's some shots of mine and it's working fine.
I have a bad Sim.....I also don't have a phone number as well..... I swiped with an old card I had and my number appeared, I guess I'll be visiting the store tomorrow to get a new one. Maybe it'll fix my 3g. Its also not wanting to let me pick 3g as an option now, just stays on LTE.
KB112 - Are you on sprint also? I updated prl/profile and no luck still. 3g still works if I am on lte and go into a 3g zone, but if I toggle it to 3g only I get no data. Wondering if its a sprint thing or a lollipop bug on Sprint, or a bad sim, missing feature activation.
Bluemgt06 - did a new sim fix it for you?
Sorry, didn't see this earlier. But yes, I am on Sprint. My 3G would work fine if I set to 3G only. Not sure why yours has issues with this?
Oddly I tried it today and it started working. I think it could have been some kind of issue with the tower/upgrades or a bug that a reset may fix on occasion perhaps.
