No 3G since FRF83

Any solution?
Only GPRS/EDGE does work, if 3G is available, it disconnects automatically until 3G isn't available.
Solution: Set to 2G-Only :-(
Anyone has the same problem?
I didn't have this problem with FRF 72.

Have you tried going into your phone settings from *#*#4636#*#* and setting it to wcdma only? I did that on mine not too long ago and no more dropping to edge for me!

does it lose complete signal? or does it show 3g still but just not doing anything?
Mine was working at first after flash. Then at about 2am it just kept trying to load then times out. Still shows 3g but just dont do anything. Im hoping its just tmobile messing with their towers... I dont see why it would work at first then not now..

The problem is, that i can only have a internet connection, when the phone is logged in into a gsm or edge network.
as soon as wcdma is available, the phone disconnects from the internet.

the signal is always available, but it looses the internet connection when it changes to 3G mode.
when the phone changes from 2G->3G mode, i see for 1s the 3G icon and then no icon will bi there.
when it changes back from 3G->2G, the EDGE/GPRS icon is visible again.

ok thanks for clarification. My problem is different. I think related to phone company.. I still show the 3g signal and even have bars, but the pages dont load and eventually gives me the check your service and try again alert....
So Im hoping soon its working again for me... And I hope you as well figure it out.....

Thank you Good luck!

Had the same issue after update, did *#*#4636#*#* and noticed I was set to GSM only. Set it to WCDMA preferred and now it's good.

Thank you very much, thats the solution!!

Thank you. Updated to FRF83 this morning and I've had a full 3g signal, just couldn't pull data all day. Could over edge. Sure enough, GSM only was selected.
AT&T N1.

I'm having the same issue on a non-rooted phone on T-Mobile. No 3G after the FRF83 update. Full bars of service and 3G displayed in the status bar. Dropping to Edge only works but there is no data with 3G.

Same issue here.
Switching to WCDMA preferred doesn't work for me though.....any help is welcome

I think it's a hardware problem with a lot of N1's.
Mine was ok the first 2 months, and later, 3g not working. This is driving me crazy ):
I have tried everything. Change the simcard, I did a reset of the data with my telcon, and nothing happens.
I've seen these problems on many N1's.
I hope google / htc release a fix for this problem.

how bout checking your bands in the service menu. so *#*#4636#*#* -> phone info -> press the menu key for more options -> select bands -> choose one appropriate for your region (ie "USA BANDS").
If all else fails do a factory reset by going to the settings -> privacy -> restore factory defaults.. of course do a backup/sync/whatever before just to make sure you can get all your apps back.
There's other ways to do a factory reset via the bootloader .. its under recovery and you press up volume or the trackball I think and you can just select all the clear/erase settings there and that should clear out everything on the phone's internal storage.
The factory reset worked for me (via bootloader) when I upped from update-1 to FRF50 and didn't have any data icon next to my signal strength. Could call out but couldn't get data.
Hope that helps.

Check your APN settings. Do a full factory reset from the bootloader. If nothing works you should call tech support again. Most 3g issues where you have issues with connecting are service/signal level related. I *****ed early about my 3g issues on tmobile and it was the network as they've pretty much gone away with improving the backhaul in my area for HSDPA+ or updates to the phone's radio.
HTC is really really really cool about swapping phones and repairing them. If you feel you have a nexus that has hardware issues call them. I did this 3 times already (one time for minor cosmetic issues with the refurb they sent) and I couldn't be happier about how willing they were to replace/repair the phone. It turns out I really didn't have any issues with them at all.. with any issues with hardware from the second refurbished phone. It was service or software related and I'm happy to say with updates/tmobile service improvements I couldn't be happier with this phone.

Thanks blisk, but the thing I don't understand is why Blackberry 9700 with T-Mobile bands, doesn't have problems at all ?
By the way, I rooted my phone , so the thing with the warranty it's complicated

I had it happen last night at work all night, but when i got home i checked my wife's tp2 and it also was doing the same thing so for levity wasn't the phone but tmobile. They started worming the same time also.... I think its tmobile.

Hello, I had the same problem with my imported n1. I'm using the tmobile version non rooted fully stock manually updated to frf83. I did a *#*#4636#*#* and selected wcdma only, rebooted and couldn't connect to my gsm network. Went in again and did a wcdma preferred, rebooted, and I works better, still changes fast to edge and G, but less often, I'm still trying it but I have high hopes its gonna be ok

Mmmm i did have problems with 3G too after pushing FRF83, but i found out that for some reason the APN settings weren't set correctly after the update. In my case the port setting after the proxy of the APN wasn't set, i changed to the correct value and it worked.
In conclusion, check your APN settings.

Just went from FRF72 to FRF83 and it's working fine.
I'm currently set to GSM auto (PRL) in the *#*#4636#*#* and I didn't change it to that after putting on FRF83.

AT&T Tab will no longer connect to AT&T data

I bought an AT&T Galaxy Tab. I confirmed when I received it, data worked, and then discontinued my service.
In the meantime I flashed to Overcome ROM, flashed to JPD to enable phone calls, brought it to Canada and used it there with a Canadian GSM provider, and now am trying to reconnect my AT&T service.
I activated my AT&T service about an hour ago, and everything seemed to be fine. I received the welcome to AT&T text message. However, it just won't connect to any data of any sort.
I've reflashed the modem to JPA, which I've seen people say works on AT&T, without any change.
I've installed the AT&T data usage widget, and it says "No Network Available or SIM could not be verified".
My APN settings by default were set with everything normal except for an empty password compared to what I found online. I tried setting a password and no effect.
Under Settings => About device => Status it shows Mobile network state as either Disconnected or Connecting.
Settings => Wireless and network => Mobile networks => Use packet data is unchecked, and whenever I try and change it, it will change to "Turning on..." and then after a few seconds it will change back to unchecked.
All of the Samsung related data connection toggles like on the pull-down windowshade or on the long press of power act like they're changing something instantly, but have no effect.
Anyone have any ideas on what's gone wrong here?

Someone stated earlier that their tab was kicked off of the network as well. I would try a series of restarts to see if the problem persists. If it does, try contacting at&t directly.
I Haz 3D!

I've restarted it about a million times in the past hour. I'll give contacting AT&T a try, hopefully it won't come up that I'm missing something from the stock ROM.

Called AT&T, they knew absolutely nothing, and couldn't help at all.
I suppose I'll try flashing a few more modems, including stock, and then I suppose I might have to reflash to completely stock if that doesn't fix it.

Try the sim card in another phone. They might not have apportioned it correctly.
Any modem will get you at least voice and EDGE, so don't worry about that now.
I have wap.cingular apn for a voice and data plan.

Hmm I'll see if I can dig something up. However, I'm a little unclear on what will happen because this is the $15 AT&T Tablet data plan, and at best I might be able to scrounge up a phone.
The sim card automatically entered wap.cingular apn on my tablet plan as well.

I was soo excited when I found this thread. This is clearly my situation exactly:
http://forum.xda-developers.com/archive/index.php/t-1083173.html
I was using the voice APN on a data plan. I deleted all the old APNs, created a new one that is just Broadband/Broadband for name/APN. Rebooted.
Hit connect, and.....it's still screwed up. Now it flickers back and forth on the status page between Connecting and Connected, and the status bar up top reflects the same - I'll see the H with arrows for a half second, and then it'll disappear again.
On the Mobile networks page, Use packet data now similarly flickers between checked on its own and unchecked and gray.

Okay, no idea why, but everything works now.
After Broadband failed to work, I tried changing it to APN Broadband. That didn't work either, so I changed it back to Broadband. Things then started semi-working in that the connection was still flickering on and off, but when it was on, data was actually being transferred.
I rebooted, and now it's fully working. Hope it stays that way. Seems to shift back and forth between H and 3G a lot considering I'm in the middle of a city with full bars not moving, but other than that, all seems well.

It would have been good to know about 1,000 word ago you only have the $15 broadband sim!
Apn is: ATT BROADBAND, and nothing else.

Hmm I have it set as Broadband, not ATT BROADBAND, and it's working for now so I ain't touch it.
Are people able to activate an AT&T Galaxy Tab on anything but the broadband sims?

Yes, I have voice and 3g data by ising a sim from my old android phone.

[Q] Why doesn't my Roaming Toggle work?

I cannot get my T-Mobile One to stop roaming onto AT&T towers. As a result, the measly 50mb/month I'm alotted goes very quickly. The roaming toggle in mobile data settings literally has no effect at all. AT&T towers are correctly identified in pulldown shade, but data is active regardless of roaming toggle position and T-Mobile is dinging me for it.
History:
HTC One purchased from T-Mobile 4.1.2 with Root - Issue described above was present.
Same handset; EU 4.2.2 Stock rooted ROM - AT&T Towers showed up as T-Mobile in pulldown shade, but data not available regardless of Roaming Toggle position.
Same handset; DEV edition rooted 4.3 ROM and firmware - Original issue is back. AT&T towers are correctly identified in pulldown shade, but data is active regardless of roaming toggle position.
Anyone ever seen this?

The Roaming toggle is for use when you are overseas and then the phone can't see any of your service providers towers
It then can log on to a foreign tower and charge you a large amount of cash for each and every MB
You need to switch of Mobile Date to stop it using 3/4G data
Unless you have failed to state your issue clearly of course
Turning data roaming on or off
Connect to your mobile operator’s partner networks and access data services when
you’re out of your mobile operator’s coverage area.
Using data services while roaming may be costly. Check with your mobile operator
for data roaming rates before you use data roaming.
1. With two fingers, swipe down from the status bar to open Quick settings.
2. If Mobile data is off, tap the Mobile data tile to turn it on.
3. Tap . The Mobile network settings screen opens.
4. Select or clear the Data roaming option.
Select the Data roaming sound option if you’d like HTC One to play a sound so you’ll
know when it’s connecting to a roaming network.

Thanks. I could go on and on about the way the toggle performs on every other handset I've owned, the t-mobile HTC One of a local guy I talked to yesterday, blah blah blah.... As indicated by the HTC doc you referenced yourself, it has everything to do with "partner networks" and nothing to do with their geographic location. Oh, and I want to tear out my own eyeballs when I see "Unless you have failed to state your issue clearly of course" in response to a meticulously crafted post. Then again... it's been a few days since the OP so maybe I'm just butt hurt that no one cares about me :crying:
It occurred to me that I got a new SIM card at the same time I got my One, so I strolled into the local t-mobile store yesterday and had the card replaced. It's a long shot, but I will be in a roaming situation again in a couple days and will update this thread at that time.

New SIM card = no difference.
Swapped SIM with wife's phone. My SIM in her nexus 4 behaved correctly, her's in my One = same problem I had with my SIM.
So, my issue is isolated to the handset.
I don't know why, but I've always thought APN settings were stored on the SIM. I noticed the APN selection on our 2 devices (One LTE capable and one not) didn't change when I swapped the SIMs so I double checked the APN settings on my One. Looks normal to me - LTE works and everything else - but I did some digging and found slightly different settings that owners of unlocked AT&T LTE handsets are successfully using on TMO, so I've applied them and will maybe get lucky when I go roaming tonight.

So what if I'm the only one here?
Anyway, different APN settings changed things BUT not the behavior of the data roaming toggle. RUU'd the phone to TMO 4.1.2 factory new, then upgraded to TMO 4.3 - Same problem.
I finally made the dreaded call to TMO and the tech was actually really good. Much easier to get him to understand the issue than I thought it would be, even though (like everyone else on the planet) he has never seen it.
This issue combined with the better-known low light camera hue problem means I'll receive a replacement handset tomorrow. Will report back here if roaming issue persists with new hardware - if only to vent to myself!

[Q] Mobile Data Issues (TMOBILE)

About 2 days ago I noticed when I went off WiFi and onto mobile data, instead of giving me an LTE indicator near the signal icon, it still has an exclamation mark, like there is no data on. If I pull down the tray, I see the LTE marker, as well as the exclamation mark. I can still surf the web fine, so its mostly an aesthetic issue, however, I'm now having problems sending and receiving MMS.
I called TMobile and they confirmed my APN settings, and kicked me off and back on the network. After rebooting, I was able to get an H indicator, and no exclamation point. At this point I was able to receive MMS, but not send. We tried once more, and I finally got LTE with no exclamation! Able to send and receive MMS just fine.
About 2 hours later, turned on data, and the exclamation point is back! I'm again unable to send and receive MMS. I figure this is probably on T-Mobiles side, but I wanted to see if anyone had encountered this before?
I'm using a rooted XT1095 on T-Mobile in the DC area. APN settings are normal, running 5.0 Lollipop.

Clear your phone cache. I've not seen this and am on T-mo.

If your APN protocols are set to ipv4, try setting them to ipv4/ipv6.

Hey everyone, after checking with Tmo multiple times, they confirmed that there's maintenance going on in the area until Sunday. Had a few other problems since then, but definitely a network issue, not my moto. Disregard, and thanks for all the help!

S6 Active on T-Mobile roaming data not working

Wondering if anyone can help me out. I've already spent hours on the phone with tmobile and they can't seem to solve it.
I've had this problem ongoing since getting this phone. Basically I get no data roaming. Places Ive tried: Canada (several cities in BC as well as Quebec and Ontario), UAE, Bahamas. I spend a lot of time in Canada so its a real issue. Things I have tried:
- Factory reset
- Upgrade to 5.1.1 using Odin.
- Try sim card in friend's phone (4G works no problem in Canada)
- A bunch of other stuff I don't remember
Symptoms:
- About 50% of the time the phone works for calls and text
- The rest of the time it says "emergancy calls only". Restarting the phone immediately restores ability to make calls/send text. This happens regardless of signal strength.
- Data connection never works. Only time I got 4G was the very first time I entered canada with this phone. . Restarting the phone would make it connect to 4G for about 1-2 minutes before it would lose data connection. Restarting the phone would bring it back. After about half a day the phone completely lost ability to make data connection and has never been able to get data connection internationally since then.
- Sometimes I get this message: "you have lost data connectivity because you left your home network with data roaming turned off". Data roaming is definitely turned on. I've enabled in settings and also via #RON# short code.

This sounds like a config issue to me. the random drops to emergency seems to be issues with roaming not being set up right. It sounds like your APNs are not setup correctly or something. have you gotten any info from t-mobile on Roaming APNs? i'm not sure if it needs to be adjusted for roaming or not.

Yeh thats what it seemed like to me as well but I went over the APN settings with them on several occasions. I also looked them up online. Everything seems correct. The only thing they had me change was APN roaming protocol from IPv6 to IPv4/IPv6.

Dial *#*#4636#*#* (on stock dialer), in Device Information try to change network settings to LTE/WCDMA.
What are your APN settings? Provide info about all fields.

Did u ever solve this issue ? I'm having the same problem...
