Calls drop

[Arilexed]

Guys,

When I got my P3600 some weeks ago I didn't experience any problems with problems with calls dropping. But ever since I've upgraded to WM6 I am experiencing this problem... the calls drop at random, sometimes I can talk for hours without any disconnect, and sometimes the call drops and I cannot even call the person back... And even after downgrading to the shipped rom, I still have this problem... That made me wonder if maybe I have had problem when I got the device but at that point I was just lucky not to have calls dropping.

Yesterday was the last time a call dropped on me. I couldn't call the person back, the phone didn't establish a new connection. When I finally got the person back on the phone (2 minutes later) he/she said that the whole time she thought I was driving through a tunnel and that I would reconnect because... I stayed connected at the other phone... After 2 minutes, she said, the connection was finally broken and that's when I was able to call again.

So sounds to me that windows mobile disconnects me and that the operators network still keeps my number connected.

Well, needless to say, I want to fix this issue. I have a 3G Vodafone NL subscription but I read that 3G could be the cause of my issue. so I've just disabled 3G. Now I'm just running on GPRS... Which isn't how I want it to stay. Any ideas, same experience/ pointers how to solve this?

Thnx. Arend

This is the reply I got from HTC:

Try to remove it off 3G go to settings / phone / band - then select GSM from the top drop down menu.

Should now reset.

If it comes up with an error, turn on flight mode then do the above again.

So based on this reply it seems that 3G might be causing my issue.

I replied to HTC:


I have followed your instructions but now I can only use gprs... but I have a 3G subscription with my provider. So even if this workaround works, it's not to my satisfaction.

Pls advice.


I'll post their reply.

Further, if someone has more info on the subject please let me know.

Same problem here...

No issues before upgrading to WM6. Sometimes the call drops out after a few minutes, sometimes a few seconds, and sometimes already after a few rings. The other day I had to make a call 5 or 6 times to finish the conversation - very annoying...

I'm running the first official Australian WM6 release for Dopod/HTC, i.e. the one that got pulled off the web for a while. Possibly going to the newer release of the ROM update solves the problem? Even though I think both versions run on the same radio ROM.

I've used the same rom as you to upgrade to WM6. But in my case, even when downgrading to the shipped rom, I still had calls dropping. And like you, sometimes after minutes, seconds etc.

Still having no drops since I have turned 3G off. But I just wanted to look something up on the internet... took minutes to get the info on my screen with GRPS, so it's not much like a solution.

This is the reply of HTC:

Dear sir,

Regarding your situation with the device , I would suggest you, to? resolve your issue with the network coverage ,to practice a hard reset on your mobile with the following step:

START -> Setting->System->CLEAR STORAGE and follow the procedure, if you have already done this manipulation , I would direct you? to this service and check the right number on this area with your network :Push the green button to call->then go to menu-> option ->Services->select the on the following list ->Voice mail etc-> and then get setting -> and check that the number is right with your network provider.


Needless to say, but I'll say it anyway, I have performed hard resets... indeed, multiple :D

The second action they adviced, sounded a bit strange to me. But when I retrieved the settings I saw that there was no number filled in for voicemail. So I've entered 1233 (Vodafone NL voicemailnumber).

So maybe the last action has nothing to do with my issue, but who knows.

So now I am running again on 3G. I'll keep y'all posted.

Just checked it on my device and there is already an entry under voice mail. So I severly doubt that it has anything to do with the voice mail settings, too.

[Arilexed]

No, I guess you are right.

Further, since I am running 3G my signal I noticed my signal is weaker then running GPRS-only. My calls have not dropped since but I do get complaints that people sometimes cannot hear what I say because my line goes dead, and a moment later it's back again.

I've got another reply from HTC:
---
If a hard reset didn't solve the problem and the problem only occurs when switching to 3G, than this can be caused by the following;

1. Problem with the device.
2. Problem with the network, ???

I would suggest to test your SIM in another HTC device with 3G and see what happens. If it happens again than it is a? problem with the network. If it works with that 3G device than it could be a faulty device. The experience is that it is related to the 3G network himself. If it is a network issue, than you can ask them to deactivate the 3G/HSDPA.

We can't find this out for you in the UK, you need to see if you could determine the problem yourself.

Thus the support of HTC.

So now I have written an email to vodafone. I'll keep you posted.

Ok... but I'm somewhat confused... are you experiencing the same problem with 1.41.00.11? Or did you solve the problem by flashing to 1.41.00.11?

[Barichon]

2----> solve by reflashing with 1.41.00.11

[Arilexed]

Ok, I've upgraded to 1.41.00.11.

So far, I've experienced no calls dropping on me.

Nevertheless, I've also made a phonecall to Vodafone explaining the issue. They acknowlegde the issue... SAY WHAT?!! Yes... they acknowledge the issue and recommend turning the device to GRPS only. WHAT?!!.. Chill, they can at least try that, who knows, maybe I would have said yes. :D

So, I explained GPRS only is not an option since it is a tiny bit slower then what I am paying for.

They've put the call through to their 2nd line and keep me informed. So as soon as I hear something I will get back to you.

ps. What I found very great is that they did not cut it off with "Ow, you are using the HTC P3600... I'm sorry, we do not support that device." Vodafone NL, keep up this great level of support!

[Arilexed]

Ok, so far I've heard nothing from Vodafone. And so far I have had one call that dropped. So although that is a huge improvement, it still sucks. :D

So... now what? The way I see it:
1. I want to have fast internet on my PDA (3G), so only GPRS is not an option
2. There are problems with the 3G network which make calls drop every now and then
3. Vodafone isn't going to fix this in a short period of time.

So the question is: what is more import to me: 3G or a reliable phone connections?

The answer is: reliable phone connection.

So I will switch my network to GSM instead of auto and when
I really need fast internet I will switch to 3G.

Case closed... well, not really... but still, case closed.

Hi

I think is not the operator problem and could be the phone problem, I am using the D810 in Singapore with Starhub and have the same problem with drop calls once I use 3G network. If I switch to GSM only than is perfect no drop calls and calls quality improve also.

So sad having a 3.5G phone and can't use 3.5G service :mad:

[Arilexed]

Could be, but HTC and Vodafone confirmed me that it has to do with the 3G network. And I do not want to know the technical details about all that so I'll leave it at that.
