@greentoy Now after more than a week, my 808 has been fine with disabled high speed packet data. So I can confirm that at least in my case the problem is definitely caused by high speed packet data.

Did you have any luck with the gophone SIM on your N8?

[greentoy]

@rnkhch -  Yes, the Gophone sim resolved the problem with the connectivity on n8.  No problems at all.  Now I am just waiting to see if anyone that has installed the leaked FP2 on 808 has the 3g issue resolved.  I have posted to several different forums, but no response yet.

I think fp2 still has the bug.

I never have had a problem with it

The one whos firmware(based on fp2) i use still says it present on his 808.

hope this helps.

Hi Everyone,

I just found this thread and have been experiencing the same issue.

 - I have AT&T here in the U.S.

 - I'm using a new U.S. variant 808 purchased from Amazon

 - I was using an N8 with an older (maybe 3-5 years) SIM card that I cut

 - Worked fine for a few weeks then started experiencing connection issues (calls & texts wouldn't come through, had to reboot, couldn't call, text, or acccess the internet)

 - Went into AT&T and got a new Micro SIM

 - Continue to experience the same connection issues (can't call out until I reboot). It will also apparently reboot randomly as I will see the loading screen , or when scrolling from homescreen to homescreen see the "refresh" of the widgets that only happens after a reboot

Has anyone from Nokia acknowledged the issue or provided any recommendations? Has anyone reached out to Nokia support yet? I am hesitant to call AT&T as it's obviously not specific to their network looking through this thread. They will probably say "don't use an unlocked phone-- and by the way, you should be paying more for your data plan."

[rnkhch]

@jondotcom Yes, I contacted Nokia support twice and gave them the details and a link for this thread. I also contacted Amazon.com support with all the details, and I was told that they will tell Nokia about it.

[jondotcom]

Well thanks for the info.

I really hope Nokia fixes this soon. The worst part is you don't know when things stop working. This morning I rebooted my phone and saw I had 6 messages waiting for me, one of which was an emergency. Things have absolutely gotten worse using the Micro SIM versus the cut one; though that could just be coincidental with timing. I guess I should say, things have gotten much much worse in the last week, to the point I'll have to switch back to my N8. Hopefully I don't have to return the 808 for good...

[rnkhch]

@jondotcom By the way, did you try disabling high speed packet data? Doing that cured my 808.

@greentoy - Just came across this thread and your question about whether FP2 fixes the issue.   Sorry to say, no it does not.

I have had this random loss of network + reboot issue for some time now, first using a SIM I cut myself, and later with a new microSIM that I obtained in my local AT&T store.   It always happens when driving in the area near my home, where network connectivity is temporarily unavailable, as well as in certain other geographic locations.   The phone always stays on all day while at work, where there is good connectivity.

This week I flashed the phone with the leaked ("Euro1"/Global) FP2 release.   I would say that since then, there has been an INCREASE, not a decrease in the number of reboots.    Now, in addition to spurious reboots at those specific network locations, my phone now also sometimes reboots right after power-on, even in offline mode. (Still a worthy upgrade though!)

I got my phone from an importer, it is a black version from Singapore. Not that I think this matters.

Will try disabling HSDPA now, and will keep you posted.   Thanks for the tip!

[ppww]

disable high speed data has solve my 3.5g bug problem, i now get 3g and no issues. hope nokia can find a fix soon.

[memo1412]

I am also experiencing this problem. Sometimes, it takes 2 or 3 reboots to regain a connection. I also have a problem with offline mode: when I try to return to online mode, it tells me network unavailable. I have to reboot the phone after which it prompts me to turn offline mode off, and then it regains a signal. Don't know if related or not...Also, if anyone has a bluetooth stereo headset, do you hear a click or pop when listening to music via bluetooth? It kind of sounds like crackling noises on old vinyl records

OK, after 3 days, I am declaring victory!  Since disabling HSDPA (in Settings -> Connectivity -> Admin. settings -> Mobile Data -> High speed packet access -> Disabled), I have had:

• No more spurious (*) reboots
• No more loss of cellular connection until restart
• No more "Unable to switch profile" message when trying to exit Offline mode.

In addition, and counter-intuitively, the Nokia Internet Radio application now plays smoother than before!  Previously playback would from time to time be chopped up and nearly unusable - now it is smooth as silk.   (I gather this might then have been a processor bound issue, it HSPDA probably eats up some processor bandwith).

Someone mentioned that this issue may be specific to newer SIMs from AT&T.  I think what I will try next is to dig up an older SIM I have lying around, cut it into a micro-SIM, and call AT&T to activate it - just to try out this theory.  I'm OK with plain old "3G" though... it seems the biggest bottlenecks in this phone are not usually related to network speed.

Or perhaps switch to T-Mobile... but I just can't seem to let the unlimited $15/month data plan go...

(*)

Since upgrading to Belle FP2, I have had a couple of system crashes/reboots that I know not to be connection related - since the phone was in "offline" mode at the time.   It seems that right after starting up the phone, you now need to wait until all background processes/services have completed loading before attempting to navigate through the UI, or it may crash. 

This, plus the Swype 2.1 "split screen" bug, makes me consider downgrading to FP1 again.
Then again... Naaah.

Just discovered this thread.  Count me as one with the intermittent network connectivity.  My 808 worked fine for six weeks then started the erratic performance about two weeks ago.  I'll try the setting change and see what happens.

[Francis1]

Besides changing the packet setting, I'm also reinstalling the phone software using the the latest version of Nokia Suite (3.5).

[trebor27]

Add me to the list of ATT users here in the US that is having the issue with loosing network connection.

I get people telling me they have been trying to call me for ages, with either no answer, or an ATT message saying I'm not receiving calls. I have no indication on the phone that I have no network connection either!

I used to use the Situations App to put my phone into offline mode over night, and recently it started failing to come back to the normal profile in the morning. It needed a reboot to get reconnected to the GSM network.

I can handle many phone bugs, but one that makes you miss phone calls is not acceptable. This is a phone right?

Or is it a camera?

[doctran]

I can confirm FP2 still has the bug. Although I never really had the bug until I installed FP2

[Francis1]

So, I reinstalled the phone software and decided to leave the high speed packets enabled to see if just the reinstall would solve the problem.  It didn't.  I have now disabled the high speed packets and will see what happens.  Right now I am traveling a lot in several counties of the SF bay area so it should be a good test. 

[93tid]

In order to try and focus the investigation of this problem I have just gone quickly through the whole thread and as far as I can see, everyone who has this problem is using an AT&T SIM card (with one exception). One person reported no more issues after using a GoPhone card, despite it using the AT&T network as well.

The problem persists on different version handsets (US or other) and on different version firmwares (FP1, FP2, US, EURO). Cut-out or original micro-SIM seems to make no difference whatsoever, problem persists.

The only long-term solution so far seems to be turning off the High-speed packet data option.

Does anyone have anything different to report  or can I try to attract the attention of Nokia's technical team to the issue as outlined above in order to investigate ?

[Marilith3602]

I have T-Mobile.

IVP6 worked for a while.

Now it is back to the old tricks again.

I am tempted retire or sell my 808.

Right now I am using my Lumia 710 or my HTC One S.

[Marilith3602]

OK, invivestigation shows the phone had defaulted back to IVP4!

Setting it back to IVP6 and testing

[greentoy]

@93tid - Actually, the Go phone sim corrected a similar problem on an old N8 I am now using because I sent my 808 back just before my 30 day window expired.  Nothing I tried on the 808 worked except disabling high speed packet access.  I could not justify keeping the 808 until this problem is resolved. Hopefully, they delayed the official FP2 release for this issue.  We can all dream, Right?
