RSU 4.21 - MUST TURN OFF AND ON TO CALL WITH GPRS???

I upgraded my XDA to wm2003. Then upgrades my radio stack to 4.21 (both Asia and UK versions).
It worked great :lol: , until recently... I could not call from my XDA phone constantly. I have to turn it OFF AND ON every 15 minutes if I want to receive and make calls.
My mobile provider is MOBIFONE (Vietnam). They recently introduced GPRS service (still testing now). And the problem started from then. In the area I had the "G" signal, I always have to use the technique "ON AND OFF EACH 15 minutes" if I want to receive and make calls. However, it seems that my XDA work normally in the area where it did not get the G signal (I can receive and make call normally, no need to turn the phone off and on).
Is it the problem of RSU 4.21? or the problem of my provider GPRS service? Or any other reasons? Can I downgrade my radio stack?
Anyone HELP me. PLEEEEEEAAAAAAAAAAASE.

You have to call to Technical Department of MOBIFONE and ask them to turn off GPRS service for your SIM :wink:
Should be OK for your phone

GPRS On O2 UK, Y is it not working?

Hi all, I hope someone can help with this,
I have tried to all O2 using 100 (but this keeps getting disconnected automatically) so I have to call as 0845 number which uses my minutes + I was waiting 30 minutes to speak to someone and when i eventually did get through they hung up (I am well Pi***d off with o2). Anyhow
I want to connect to the net using GPRS, however no GPRS symbol is displayed and if i try, i get a message saying "No moden at above number" any help would be great.
Cheers
Matt

Right, couple of things to suggest.
Firstly (and I know this sounds stupid)....O2 have recently installed new call centre handling "things" which SHOULD route your call more efficiently but as they have been put in by IBM (also, responsible for more recent "good inovations" in O2) the bits aren't working v well! - trust me as I speak from experience and "from the horses mouth" - I work for them!
So chill when you do get through....the staff on the phones are getting major grief from customers, dealers and fellow staff members (mainly store staff) because it's taking ages......It's not their fault!!
Anyway, back to your problem.....you haven'y said whether you got a new connection or an upgrade.....if it's the latter did you ahve GPRS on your previous phone and did it work?
If it's a new connection then GPRS hasn't been provisioned for some reason (although it can tkae 48 hrs max from connection to go through), same goes if it was an upgrade and you never used GPRS on the old phone.
Give me the answeres to these questions and I'll give you my best guess!
Mike

Check settings
I use this site for settings:
http://www.filesaveas.com/index.html
I would also suggest that you check that GPRS has actually been enabled by O2 for you. I had problems with MMS not being enabled although I HAD asked for it.

Thanks Mike for your responce, and I promise not to go ape at your colleagues.
I have a new account with O2, connected today, however seems strange that it could take upto 48hrs to get GPRS active, I was recently with ORANGE and as soon as I activated the phone (a SPV) the GPRS was active there and then. Ah well I will wait the 48hrs and hopefully it will come active sometime soon.
As an O2 employee, you may be able to assist on this query. As a paymonthly customer on O2 400, I am supposted to call 100 from my XDAII to call CS, but when I do this I get disconnected automatically as if the number is dead, any ideas?
Many thanks for your help.

An update on the aboe. I have managed to sort this problem out, I did a soft reset and when rebooted I noticed the phone settings were on Germany, changed it to UK and GPRS works fine.
Matt

for anyone searching with this problem
MODEM NOT FOUND AT DIALED NUMBER
1. phone CS on 0845 and make sure GPRS is on! (APN provisioning for mobile web access (you can 'check' on the 100 number, but they can't turn it on for you)
2. 3.30pm is the 'switch over' time, so soft reboot after this time each day (
up to 24hrs) ...... phone again if still not on !
3. GERMANY is default if you go to MY XDA - connections. it will always be on Germany. but the wizzard should of set it to UK when you first set it

Do you have the correct settings for wap over gprs, email over gprs using O2 payg sim with free gprs pages and wap.

Is there any portal to get the settigs to the O2 phone directly?

GPRS can not reconnect after receiving incoming call!

Hi everyone,
I am having an annoying issue with the GPRS connection on my Qtek S100.
I am usually connected through GPRS to receive my email and to be online with MSN Messenger. The only time I do not use GPRS is when connecting through Active Sync or when making/receiving a call. My problem is that if I do not explicitly end the GPRS connection before making a call or connecting through active sync I have to restart the phone by going to flight mode before I am able to get a new GPRS connection. The problem is even worse with incoming calls as I can not end the GPRS connection by pressing the red button before I answer the call as that will hang up on the person calling me instead.
I believe it got this way after applying the latest software upgrade from www.qtek.se.
Is anyone else having the same problem?

yes me to.. also after latest upgrade...
dont know what to do.. im gonna call brightpoint..

I've sent you a PM.
Let me know when you have spoken to Brightpoint and I will call them again.

Any news regarding this?
I do also have these problems with GPRS.

Works fine for me…
Hi,
I have up till now used Telia but just switched over to Comviq, works fine for med, both with Telia and Comviq.
// Johnny

Talked to Brightpoint today.
It seems like not everyone gets this problem, and to their knowledge none of their own phones has it. They did however hope for a solution with the next software update (no news on when that will be available though). They also asked me to contact Engström Telecom to find out if they had any idea. When I found time to call Engström they had closed for the week, so I'll get back with more info next week.

I had a slight variation on this problem. GPRS session was actively downloading data when a call came in, and then before I could answer it, a message came up saying that the call could not be answered. What's that all about?
Ian

My problem seems to have automatically cured itself during the weekend. I guess Telia must have made some upgrade to their network, cause I am quite sure I didn't do anything!

P3600: Sometimes, calls get forwarded to voicemail without the phone even ringing

Hi. I am using the P3600 since February 07 and have noticed that sometimes callers are being forwarded to my voicemail directly without the phone ringing. I checked the service settings (diverts), and what I do have enabled is a divert to voicemail *if the phone is busy, unavailable or out of reach*.
I am using Pushmail / Activesync via UMTS and ask myself if the phone is dropping in a "busy" state while downloading new e-mail. If somebody would call exactly then, this could cause the divert to my voicemail.
Did anybody have a similar experience?
Thank you and best regards
Stefan

Hi
On German Vodafone this happens if
a) HSDPA is enabled
b) you ar online with a data connection
c) you get a phone call then
I disabled HSDPA and the problem is gone.
which network do you use?
do you have HSDPA enabled?

I've had the same issue. I have Cingular/AT&T. They tried troubleshooting the phone, and ended up sending me a new one. Weeks later I find that I'm still having this problem. If you find out an answer let me know...

HSDPA in use
Hi - thank you for your reply. I am in Switzerland, and I use Swisscom as a provider. HSDPA is one of the option the phone goes for if no other is available. Is there a way to disallow the usage of HSDPA? Thanks and best regards, Stefan

Yes, there is. Try SK Tools. There is also a HTC Tool for this and http://www.fit4cat.de/portal.php has another tool. If you have problems finding one of these tools then send me a private message with your email adress.

Thank you - I will check tools out
Thank you very much - I will check those tools out!

Hi, guys!
I'm from Ukraine, and my operator doesn't have 3G yet, only GSM/EGPRS.
And I don't use voicemail but there is lighter service here. If somebody called me when I was unavailable, out of zone I would receive SMS from operator with callee's number and call time.
And after switching to P3600 I began to receive such SMSes 5-7 time per day even if I'm sitting in my office all the time and is available.
I've written e-mail to HTC support but haven't received answer yet

does not happen only with P3600
I switched my SIM-card to a Sony Ericsson P990i - and was stumbling into the same problem. Calls sometimes get forwarded directly to my Voicemail if data connection is active. It seems to me rather a provider than a device problem ... ! I will discuss this with Swisscom. Thanks for the hint.

Unable to make or receive calls

I wonder if anyone can help with a fault on my M3100. So far I've searched this website for answers with no luck. I have Hard Reset the phone, upgraded the Radio, all without any luck.
About 6 days ago my M3100 suddenly stopped being able to make or receive calls. Whenever I try to dial out the call drops out before being established, and if I try to call in to the phone the caller receives a series of beeps.
At first it seems to be a SIM problem, but the Vodaphone SIM is fine in any other phone. If I put my Orange SIM in the phone it just comes up as "No Service".
I'm at the end of the line in what to do and it doesn't seems to make any sense.
Any comments, suggestions, advice or help very much appreciated.
..... Further symptom details:
I can send and receive text message with my Vodaphone SIM installed and access WiFi and GPRS networks. Orange SIM won't connect at all! Both SIMS work fine in a standard phone ! Only clue I can think of here is that the Vodaphone SIM is UMPTS and GSM where the Orange is GSM only. The spare phone I tested them in was GSM only.
Could the GSM part of the M3100 be stuffed ?
I'm stumped for the time being!! It doesn't seem to make any logical sense. Maybe any of you who know the in's and out's of how the device communicates might find some clues in that...
Heeeeelp !

More details..
I've just added a few more details on the symtoms.. maybe the few extra clues might yeild some thoughts from someone !

Have you checked the band selection in Settings > Phone?
Is it possible that the phone could have become blacklisted? How long have you had it? How did you buy it? (This is probably NOT it, since the text still works.)
Have you tried a tweaker to enable HSPDA?

Had the phone for over 12 months so Blacklisted shouldn't be the issue. I've tried all the band selections including Auto but no luck.
Haven't tried the Tweaker... do you have any details on that...
Up until it suddenly stopped working it worked on all networks..
Another possible clue is that I was "Roaming" in France for a month and it was there that I made my last successful call. I have UK SIMS... I have an Australian SIM which I'll try now to see if that makes any difference..

Tried an Australian SIM roaming in the UK ! The service connects on two available networks,Vodaphone and TMobile but not on Orange and O2 (like with the Orange UK SIM). Same fault as the before with the networks it will connect to.
This seems to eliminate the SIM or Network being the fault and isolate the fault to the Device...

probably not the issues, but worth a try?
I live in a very strong 3G + HSPDA ares, but cant make or recieve anycalls tho texts work on T-mobile, i need to have my phone in 2G mode, and calls work fine???
If i leave my house and go a few miles 3G works as it should able to call and recieve etc!

Can't seem to work out how to force the phone onto 2G or 3G ... if anyone can advise I'll give that a try!

I have had very similar problems to this.
Please see my post:
http://forum.xda-developers.com/showthread.php?t=325149
I do think this is some sort of network problem as after I posted the issues in the thread above, I left home and travelled about 6 miles and the signal came back and the phone worked fine.
Today, I have been able to make and receice calls but all of a sudden I got cut off from a call then could not make or receive calls (incoming goes straight to voicemail).
I can however use my Orange SIM without problem and both Vodafone and Orange SIMs work fine in other phones.

You can also go into Settings > Phone > Band.
If the band tab does not appear (to the right of the network tab), then you may need to do a registry tweak.
From the very helpful wiki:
Enable/Disable GSM/UMTS Band Selection
Cingular kindly disables anything useful about the network on the 8525. To enable the Band Selection Tab on your Phone settings page, set the following:
[\HKLM\Software\OEM\PhoneSetting\]
"ShowUMTSBandPage"=dword:00000001
To disable, simply clear the value to 0:
[\HKLM\Software\OEM\PhoneSetting\]
"ShowUMTSBandPage"=dword:00000000

Have travelled outside England again this week and... well the phone works fine roaming on my UK Vodaphone SIM. Seems very ODD.. only thing I can put any logic to is a problem with the GSM part of the phone. It's working here in Stockholm on the 3G network no problem.
Anyone advise how I force the phone to be on GSM and 3G so I can test this theory. The BAND settings under SETTINGS>PHONE don't seem to give you this control over how it connects..

Hey i got the same problem anyone solved it yet!

Hi Sunnyb1
Since my last post I returned to England where the phone was useless. No SIM cards would work, some would not register at all but my Vodaphone SIM seemed to register but as before it would not receive calls, nor could I make calls out.
Now I'm in Australia with an Australian SIM card. NO PROBLEMS AT ALL !!
The phone works just fine !!
It's a mystery indeed...
Without any knowledge of the ins & Outs of how a SIM card / Network / and the phone work together it's impossible for me to arrive at any conclusive logic.
Hopefully someone might stand up to the plate and offer some explanation !
Anyone from HTC out there ??????
Steve

I got the phone and it was working perfectly on Orange then i tried unlocking it and ever since it has come up with "NO Service" like you everytime i put a Orange Sim in the phone it does not show up.. but when i put a Vodafone sim it works perfectly i tried reflashing the radio's many times

I unlocked this particular phone 6months before this problem showed up so I don't think the Unlock on it's own is the cause. What's particularly baffling is that a SIM may not work with the phone in one country.. but in another it works fine.

..... another country that is !

Hey Steve i have found out what the problem is after hours of research
I found this of another website
Orange & O2:
If you place an active orange or
O2 sim into a blacklisted handset you
phone will not show any signal strength
at all! If the handset is a Nokia then a
"SIM card registration failed" message
will also be displayed. If your handset is an
Ericsson then an "Invalid Mobile" message
will be displayed. For most other manufacturers
the handset will simply show no signal!
Vodafone & T-Mobile
If you place an active Vodafone or T-Mobile sim into a blacklisted handset, the phone will appear to function perfectly UNTIL you try to make an outgoing call. When you try to call out from the handset you will hear a sequence of beeps and then the call will be dropped!!
........
This means the handset you got is stolen or someone has blacklisted it ... i got mine of EBAY! and reading that i figured that it is stolen
It wont work in the UK but it will work everywhere else in the world

Mmmm... that's interesting Sunnyb1. If my phone is blacklisted then happened in JULY this year which was 8 months after I bought the phone. I bought the phone legit .
Can anyone advise what the "Blacklisting" process is.. I assume its done by using the IMEI number.
Who is the rightful owner of a handset and can any phone be blacklisted by anyone, and possibly by mistake ?
Would unlocking the phone from Orange cause a phone to be blacklisted ??
How can you "Un-blacklist" a phone.

Answered my own question here......
This website seems to have the answers
http://www.unlockme.co.uk/blacklist.html

OK... still on this thread. Can anyone advise how you find out which network in the UK has blocked your an IMEI number. I gather any of the UK networks can block any IMEI and it's not unknown for errors to be made. But only the network that blocks the IMEI can Unblock it.
Thought I'd post this before waiting forever for some call centre dimwit to give me the runaround.
Thanks...
