Just a heads-up
I have had the Vox for a couple of weeks here in Sweden
It is being used with Active sync towards an Exchange 2003 over GPRS
I quickly noticed that suddely it was not possible to receive SMS or incoming calls, the calls just got redirected to voicemail, after a reboot the phone started working for a while again, but it kept coming back.
After a couple of discussions with HTC and the distributor (and 2 rounds to the service partner for more extensive tests only to say that the phone was fully functional...) I now know what the problem is, and I put it here to let you know.
Aparently here in sweden and the rest of the nordic coutries we use GPRS type B
See here for a spec:
http://www.gsmworld.com/technology/gprs/class.shtml
And the radio stack in S710 has trouble switching between GPRS and GSM
What they told me is that HTC are working on this, (and they better be and fast...), because without a fix GPRS is useless on this phone it could anytime hang in either GPRS or GSM mode, resutling in nonworking GPRS or (even worse) no GSM, you only notice this on the fact that incoming calls are not working, outgoing calls works.
So the only way to test is constantly call your own phone to see if it is still working.
The only fix I have found to this so far is to disable all GPRS accounts and reboot the phone...
Just thought I should share this information with you. I have a feeling that more people will experience this, and I had to do a lot of digging to get this information.
If someone else has some more information or experienced this I would love to hear about it.
Thanks for the tip.
Got my S710 yesterday evening, did the GRPS setup today afternoon and tonight got couple of calls redirected to voicemail... Yep GPRS was on (although I wasn't actually doing anything, just noticed the "E" icon for an active connection). Thought was only bad reception... Knew about the missed calls because of the SMS telling me right away somebody had called.
Anyhow, SMS were getting in... Maybe it's not related to the same problem... Hopefully was really only bad reception, but enough reception for SMS.
I'll do some more testing tomorrow. I can't afford missing work calls or I know I'm fired by listening my voicemail.
Thanks,
Ka.
Ok, time to disable the GPRS settings... Let's hope they make a bugfix soon for this.
thats really worrying. has anyone experienced this in the UK ?
The whole point of the S710 is so I can have IM and push email and phone on one tiny device with keyboard
I think this is all related to the GPRS class B, what I understand so far at least is that this is mainly a problem in the nordic counties where this is used (I may very well be misinformed, this is new to me, I have a diploma in GSM technologies from a short course but that is not even worth the paper anymore )
If a network uses Class A, this is what I am told not a problem, and Class C seems mostly useless everywhere, look at my link in my first post and read about Class C ,you will see why
Kast, that sounds like a slightly different problem, I don't get SMS or calls when this happens, you also have access to EDGE and that may not have the same problem (don't know). But it would either way be interresting to see if you experience problems.
gprs class b
The class of GPRS (class B) is parameter no to gsm provider. This is spesification on device htc s710.
I have also htc s620. Result of my testing is that this device is working on Gprs Class B. When i made sinhronzation to exchange server then you can't call my gsm number, but when my sinhro is done you can call my gsm.
The bug on htc s710 is very serios i hope that from htc make quickly patch or update to solve it !
definitely all working fine on my new S710 in the UK. Will be trying in NY next week .....
Yes I think the problem is definately in Tele2's network in Sweden but probably also the other networks hera as well as in Denmark, Norway and Finland
That is what I've been told anyway. But thanks for the info
htc-s710
gd day friends
have just tried this issue on a orange il simcard and no problems were found
i can get calls and sms while gprs is on !
thanks
Then orange has GPRS class A (I wish they had that in sweden as well then we would not have that problem here...)
I have the same problem with a HTC Tytn in Belgium with Proximus, whenever the GPRS connections is enabled, calls tend to be blocked and go directly to my voicemail. Only fix is to disable the GPRS connection and only use it to check your mail every hour or so.
If I remember rightly, All GPRS phones are class B anyway. Never come across a class A GPRS handset yet (or if i have, it was never plugged as a class A device).
what tends to happen is that the network and the phone will negotiate to suspend the GPRS connection when there have been no packets sent for a certain amount of time to save the power on the handset and the towers, and to optimise the bandwidth to accomodate as many users as possible.
Seems your network might have this suspend timeout set a little too high, or alternatively, I suppose the network infrastructure could be Class B and therefore not support it at all.
I'm sure there was a reg hack around for earlier smartphones to make the GPRS connection disconnect automatically after 30 seconds or so. seems you might have to set activesync to check avery so often and see if you can find this hack.
ubfortunately, this is always going to be an issue on GPRS/EDGE devices if you are a heavy email user....but the networks still want the handsets, so they will still be made.
Hi,
I donät think the problem is with the network timeout, I have used the similar setup with Nokia handsets and Sony-ericsson and the correctly suspend the GPRS and then resume it after a finished call. But this phone seems to hang in the GPRS mode, then network is trying to send the call to the phone but the phone is not able to pick it up.
I think you are right that the registry hack might help, have not tried that yet, don't know if it is the same in WM6 either. But I might give it a try, now I have solved it via WLan at work and no e-mail elsewhere :-/
Did a bit of testning with the registry keys found this thread
And changing the first key
DWORD CacheTime
60 - Timeout in seconds
String SuspendResume
~GPRS! - Always On
GPRS_bye_if_device_off - Timeout after CacheTime
This works, setting the timer to 30 seconds automatically disconnects the GPRS session, next is to see if the phone stops receiving calls or if it still works even with GPRS activated... Let¨s keep out fingers crossed
Solved this (at least temporarily)
The registry edit seems to solve the problem at least eough for me to receive e-mail at scheduled times and receive calls.
However this is not a final solution, still waiting for a radio update from HTC...
And there is always a risk that the phone stops working during the rime GPRS is active...
I have a s710 also. I'm having missed calls very often, people are complaining they can't reach me. Sometimes after a certain period a sms arrives that i haved missed calls.
I use GRPS constantly due to the syncing with exchange (push mail) at my work.
Is there a solution for this problem yet?
You should try the radio in the Arabic rom (do a search).
It's the latest version.
After much experimentation, i have found the following:
1. If i boot up my phone WITHOUT the USB cable attached, and i start transferring data from the internet, my phone will not allow any incoming calls. They all get sent to voicemail.
2. If i boot up my phone WITH the USB cable connected (which happens to block GPRS data), but THEN DISCONNECT the USB cable so i can activate a GPRS connection, when I start transferring data from the internet to my phone, it will pause the data transfer and allow incoming calls to ring through to the phone.
My company has C500 ( Vox in Asia named Dopod C500 ). We suffer from the same problem that everyone in this thread are talking about....hang and incoming calls blocked. The only way to solve is romove the battery to reset it.
HTC Thailand gave us the -new hope- ROM which I believe it was modified from the Arabic ROM. But no improvement.
Anyone get the solution?

I am tired of making callbacks, somebody pls help
Both my brother and I bought Fuze's last week and he has recently been having trouble with his.
Unfortunately I live on the opposite coast so I can't troubleshoot his phone using the hands on approach and instead will try asking here
The Problem:
After working splendidly for the past week and a half, my brother has noticed within the last two days that he cannot send or receive calls regularly. When he is able to receive a call or make an outgoing connection his call quality is significantly distorted and garbled, often ending in a dropped call. Also when people place a call to him it is often the case that the phone doesn't even ring or show up in the call logs and he is only made aware of the call if someone leaves a voicemail.
I insist to him that this is not the phones fault and instead a service problem with the fault belonging all to ATT. I remember having the same problems with my 8525.
He is adamant to the fact that something must be wrong with his Fuze / Touch Pro. He says that when he pops his sim card into his old krazr (for which the Fuze is replacing) all the problems disappear. He also insists that he has full bars and 3g service at his location.
Background:
Via mymobiler and remote desktop, I added YouTube and Live Search back to the internet tab. I added a few cities to the Weather tab using the WeatherDatabaseEditor from andreas.falke and also reverted his phone to the original Black Touch Pro theme (found here) using Diamond TF3D Config 0.6.7.
I also removed the forcecell connection registry entry to allow him to tether his phone.
I believe none of these tweaks would have caused his current problems and still believe the blame mostly falls on ATT's service.
Any advice, help, or comments into this matter would be greatly appreciated!
You could have him try flashing to a different radio just to test. They don't hard reset the device, and as long as you use another TP radio you don't need to be security unlocked.
If that doesn't work, flash back to the original radio and I would bring it in for service.

I suggest he reverts back to the original theme because whenever I change my theme I cannot make calls or receive calls but when I go back to the original theme calls work perfectly. Please let us know your result.
Hi I have a problem of the HD2 of outgoing calls when I call someone and when you receive a call, hang up immediately when another call is already so good. I've tried everything I returned the phone to its original state, the operator has examined me several times a SIM card and confirmed to me that everything is correct this error occur with a prepaid SIM cards for lump nikoliv.Při the unsuccessful telephone call to report, beyond the limit of ACM, you do not know where it could be a mistake of which I am unhappy, thanks for any advice.: Mad:
i had this problem. im not sure if this is your case, but when your call automatically hangs up, it means that you're on the other person's blacklist (at least for android). check with that other person and see if thats true
Hi I am from Czech republic your contribution I have translated the translator over because I can not English, but I do not understand could you closer to me I'd be grateful. They thank in advance
check your inbox
What?? What control of my mailbox?? my problem of outgoing calls ..
i mean check your inbox on xda (top right corner, select private messages). i sent you a message
Hi, this is not a problem (Blacklist). Suspension call is executed only once after the second attempt, everything ok then it repeats from a certain time delay when ever call. The flat SIM card, this problem does not occur other vůbec.Zkoušel I GO (rechargeable) SIM is still the same.
Hi Blacklist certainly not with repeated calls had everything in order, after a while the error is repeated again. Error occurs only on a prepaid SIM card SIM card to lump everything ok.Myslím think that this is a hardware fault phone when the phone from the Android system playback on Win.Mobile 6.5 and I will bring restoration and lock (SPL), so it's still stejné.Omlouvám behind my lot do not speak English.
Hi
I just bought an XZs dual SIM version. I'm having a very strange issue with it.
I have two SIMs installed: one on O2 UK and the other on Three UK.
The three chip works perfectly. Can do everything, voice, data, SMS etc... all good.
The O2 chip however has a strange issue. Every phone call I make it says "Invalid number".
Even if I call using the international +XX XXXXXX type or if I call using the UK style 07XXXXX both say "Invalid number" and do not complete the call.
What is odd is that I can receive incoming calls to the number. SMS and data also works, just making outgoing calls fails.
I checked that the phone supports the bands that O2 uses and it does. It does connect to the network (as I said I can receive calls, use data, send and receive SMS but just cannot make any outgoing calls)
The phone came from Hong Kong, and both O2 and Sony have flat out refused to help because I didn't buy the phone in the UK.
But well, it's a mobile phone, it should work in my country even if it's from HK.
I cannot really understand why I can receive calls but not make them. The SIM card works in my UK Samsung S6 so I do not think it's a network issue.
I have tried setting it to GSM only as it is my work phone and I really only need it for making calls. I've tried WCDMA / 4G / 3G but nothing fixes it.
I have reset the phone. Checked carrier settings etc.
Lastly I have tried swapping the chips around, and tried it with just one SIM but still the problem occurs.
Please can anyone give any suggestions on resolving this issue before I have to send it back ?
Thanks!
never mind. i solved it.
it was a provisioning error by the network, contacted O2 today and they resolved it by doing some kind of reset their end, which they didn't want to elaborate on.
fixed now.
Hi,
I have not been using my OP6 because of a strange issue with it since OOS 10.3.9 (maybe since May 2021)
This issue is: I can not make nor receive normal call with any provider. but my network bar is full and my 4G internet is running smoothly.
If I try to make a call, it just show the call screen, no calling tone and no waiting tone and the other phone doesn't ring.
If I try to call my OP6 from other phones, it just doesn't connect, no call tone no waiting tone... My OP6 also doesn't show any incoming call.
I'm sure my sim cards are OK, I have tried to put them in a different phone and they can make normal call.
If my sim card slots were broken, I would not have any coverage and my 4G wouldn't work...
I can receive SMS just fine.
anybody can help me?
thank you
I had the same issue, at the end oneplus said, bring it to a service center while there plenty or forum posts in their forums from technician saying it's the network chip, i got a new phone but will attempt to replace that chip once i got my replacement.
You could try other stuff, full wipe, other roms etc.
