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?

on my S710 i can receive calls but the caller cannot hear me.
but when i make a call its perfect.
I am tired of making callbacks, somebody pls help
I have read many people have had problems with random phone restarts when making or receiving calls, but my issue is much more specific.
I'm surprised my Googling hasn't turned up anything on this problem, as my Touch Pro is running a stock rom (from 3 Australia), and issue was occurring before I installed any additional apps.
Issue as follows:
Model: HTC Touch Pro T7272 (Raph100)
ROM: 1.90.861.7 WWE
Radio: 1.02.25.19
Protocol: 52.33.25.17U
When connected to PC via USB and Windows Device Mobility Centre is active (the Vista version of Activesync), whenever an incoming call is answered, the phone restarts / reboots itself within a second of answering the call. I don't know if this also happens when making a call as I haven't tested that yet.
** Edit 1 **
I have now tested outgoing calls and the phone does not reboot / restart, so this problem is limited to incoming calls only.
** Edit 2 **
Restart also occurs when mail is syncronising over a GPRS/EDGE connection and an incoming call occurs. Appears issue is somehow related to Activesync or mail send/receive (in this case it was an IMAP mail account).
** Edit 3 **
I've found another reference to perhaps the same issue at http://forum.xda-developers.com/showthread.php?p=2827920 where the phone would reboot within 30 seconds or so of making a call when roaming. My house (the only place I've seen this issue now that I think of it), is in a roaming area for my carrier, so this may be the same issue. Mine definitely only reboots during a mail send / receive though (not sure if normal data transfer will cause this - haven't tested yet).
** Edit 4 **
Reboot occurs during ANY data transfer on EDGE/GPRS when an incoming call occurs. Tested by updating weather whilst calling phone from landline. It appears the Raphael doesn't know how to handle the fact that Voice and Data aren't supported on GPRS/EDGE simultaneously, so it just poos itself and reboots. Although I originally thought this was somehow related to an active WMDC connection via USB, my phone must have been syncronising mail via the GPRS/EDGE connection (as I'm roaming here), even though it was plugged in to the PC. I have now confirmed that so long as data isn't being transmitted via GPRS, calls can be received or made whilst it is plugged in via USB and Activesync/WMDC is active.
** End Edit **
As I do more tests I'll add more information to this post.
I'm experiencing the same problem here also.... I'm with 3 and when the phone is roaming on the Telstra network, it will reboot within 30 or so seconds of receiving an incoming call.
Just want to add that I can reliably crash the phone if I make an outgoing call whilst roaming (easily done, my house is in a roaming area for 3), and I go into my mail client and select send/receive... bang... restart.
Another 3 customer with same issue
Hi guys.. Just wanted to drop myself in as another user with the same issue.
I thought it was a doa handset and took it back but new one doing the same thing (when roaming)
Has anyone tried any other rom on it?
Cheers
I have a colleague with the same phone and ROM as me, so I will test with his device today to see if the same thing happens. I suspect the Network 3 Radio stack is dodgy, so I'll be letting 3 know about this as soon as I confirm whether this is happening on my friend's phone.
There's another person having this issue here;

how do i hack the registry, so that when an incoming call is received, to turn of GPRS.
I have a problem with my network, when GPRS is downloading, and an icoming call is received -> the device restarts.
Thanks

Okay, have now tested this with my colleague's TP (which has same ROM, Same radio, same carrier and so-forth), and his TP DOES NOT RESET under the same circumstances!
This being the case, it looks like a hard reset is the logical next step as something must have gotten buggered up somewhere along the line!
Now to look up how to hard reset these things....
I'll report back with my results.
Okay, Hard Reset fixed it.
I read somewhere in XDA-Dev that a part of the OEM setup you see when you first start the device has already been completed (either by 3 or someone else further up their supply chain). I can confirm that after the hard reset, the setup process was slightly different (longer), than what I saw when I first turned the TP on out of the box. Whether this has any bearing on things I have no idea.
I will now begin the laborious process of installing and tweaking everything as per my requirements whilst testing this restart-on-call issue in-between each step to see if the issue arose because of something I did.
I'll report back either way.
After a day, and all software reinstalled, I don't seem to have this issue anymore. I can only assume that this was due to some setting / configuration which was made by 3 or someone else up the supply chain before I received the phone, or maybe one of the configuration scripts didn't run properly when I first turned on the phone. Either way it's working now.
Codenix.
guys, just letting you all know that my phone is a non-3 HongKong edition, it has RomeOS2 on it and the latest radio. I haven't tested it in a couple of days, but since mine hasn't been "touched" by Three, I doubt it has to do with their ROM or Radio

Edit: and my phone is still crashing.
Mine crashed again on the weekend, so either the problem was intermittent when I did my testing the other day and didn't show itself, or something I've installed since then has caused the problem.
The only thing which springs to mind is the latest version of Google Maps which I installed on the weekend, and which I had also installed prior to noticing the reboot issue before my hard restart.
Thanks for your input Sawbones - at least this confirms that there's nothing specific to the Three ROM causing this.
I surprised many more people aren't also experiencing this problem. Perhaps most people rarely roam.
I have the touch pro and use this India. I have the same problem while roaming. I have installed BlackBerry Connect and whenever i am on EDGE or GPRS, the phone crashes and reboots when I receive an email while I am on an incoming call. I haven't found a solution yet.

Any luck so far? I have the same issue in India. I have tried every single trick that i know off including updating the ROM and flashing a new Radio (1.02.25.28 - saw it in another thread that this is a good and stable Radio Version.). It is very annoying that everytime i receive a blackberry email when i am on a call the phone would reboot
-Radha
No luck here. I thought the reset had fixed it, but perhaps my testing wasn't very good as I had to force my phone to roam, unlike when I am at home and I'm outside my provider network area.
I'm surprised more people aren't reporting this issue though.
Surprising indeed. Not many are complaining about this it looks like. I have been searching the Internet relentlessly to see if anyone has solved this but to my bad luck there is none.
The phone crashes if i receive a call while i am updating my weather. So far i have tried the following Radios:
1.01.25.16
1.02.25.11
1.02.25.19
1.02.25.28
1.02.25.27
1.02.25.31
1.02.25.32
The phone crashes on the said problem consistently. I even recently updated my ROM to ROMeOS 1.40 and repeated the above Radio's to verify. I am able to reproduce this problem with:
* Blackberry Connect receiving emails while on the call
* ActiveSync Receiving emails while on the call
* Updating Weather
Basically any data connection being active.
I am extremely frustrated with this phone and thinking of dumping this phone and go back to my TYTN II (Kaiser) which was perfect and worked with EDGE/GPRS and BlackBerry flawlessly.
- Radha
+1 Here, tried different ROMS, different radios and even different SIM cards, I guess it's goin back......
Same here guys. Im on 3 and when I roam to Telstra GSM it dies very soon after. This is very annoying and HTC should fix this as a matter of urgency.
Rename thread to "Raphael restarts on call when roaming"
Can a moderator please rename this thread? The issue is not related to wmdc as I originally thought.
Thanks.
Codenix.
Happening to me as well (and i am trying to support 4 others in our business).
If only 3 would have some bloody coverage it wouldnt be such a problem.
Has anyone tried the new ROMs for Optus/Vodafone?
Or could it have something to do with turning on/off HSDPA?
Is there a way to stop data connections when roaming? so at least we could use it as a normal phone when roaming.
I hear that someone used an old .cab file from their Fuze and got Internet Connection Sharing working on their Verizon TP2 ? Can anyone confirm / share the .cab?
Also, I know "conferencing" is disabled on the Verizon TP2 but I have heard you can still do a 3-way-call? I have not been able to figure this out - can anyone fill me in?
Thanks
oh my god!

I cannot do a conference call... I called tech support and they told me to just dial second number and press send. then send again to connect all 3 call. Nada... Nope. does not work.
We need some xda cooks to restore the htc conference call software! asap!

Info on 3-ways calls straight from the HTC manual located here: http://member.america.htc.com/downl...ro2_Verizon/HTCTouchPro2UsersManualforVzW.pdf
This if for CDMA mode, GSM mode is also in the manual.
Making Three-way Calls in CDMA Mode
To set up a three-way call, directly dial the participants and add each connected call to the three-way call.
Starting a three-way call
Press the TALK/SEND button to open the Phone screen.
Make the call to the first participant. See “Making a call from the Phone screen” for instructions.
When the first call is connected, make a call to the second participant. The first call is put on hold when
you dial the second call.
When the second call is connected, tap Flash to start the three-way call. The screen displays Call in
progress.
Tap Flash
When a three-way call is in progress, you can open the keyboard view the call in landscape view. You can also
tap Flash to cycle between the three-way call, Caller 1 only, and Caller 2 only.

No need for a Fuze cab for ICS or anything like that. Just download the attached XDA WiFi sharing cab and you can turn your phone into a wireless router and connect from any wireless PC/laptop that supports ad-hoc wireless networks (basically all of them).
See the other post above for directions on the 3-way call.
Nate
can someone with a verizon tp2 try 3 way call?
i tried method using flash button. i tried method of using send button. it does not work for me in nyc area. if anyone can try this to confirm it does work it would be much appreciated.
while on a call i pull up keypad. dial number and press send. i get a notice that new call is on hold. (which is opposite what is implied in the manual) i press flash button and new call disappears. only on original call again... what am i doing wrong?
I tried this once right when I got mine and got similar results as you.
I'll have to try this again, I'm rarely making 3 way calls from my cell.

Hey, I answered this exact question on another thread as far as tethering. I have VZW and these instructions I posted worked perfect. Check here for all the instructions you need to tether using your unlimited data plan.
well.... supposedly it works now. I called tech support. she grabbed 2 cell phones. she called me and we connected. then I dialed the number of her 2nd cell phone. I hit the send button and after she picked up and I heard her voice on the line I hit the send button again. and she said both calls were still connected. hmm... So I guess it does work. although on the phone screen it just says connected. No indication connected to what??
So does that mean nothing was ever disabled on the phone... just that the network didn't support it?
Hi I'm having no luck dealing with net 10, and I'm hoping I can get some assistance from you fellas here at xda . About a week ago my phone stopped making calls, when I try to dial out it says server unavailable. I can make texts when I send them it says sending forever but the text still goes through. I can receive texts , cannot receive calls and my internet works perfect. Net 10 is thoroughly convinced that I have a defective phone and after they have provisioned it 10 times nothing has changed . They had me factory reet, then after that failed has informed me I have a faulty device. So I bought another one and what do you know see problem .
Besides the fact that these people I don't think know anything about what they are talking about I am going nuts.
Here's what I have tried and some info I think may help
I have turned off volte and enhanced calling . Nothing happens .
My phone is the tcl lx
Net 10 Verizon sim
In phone info everything is right but voice network type says unknown
I have never seen this before but in shortcut maker I had 6 separate operator plugins activities. After whiping phone 2 remain the first just crashed second pops up a box saying switching to lte for better voice quility
Thanks I can provide any info if it will help
Using the device on T-Mobile. Sometimes I'll just get a voice mail notification - without the phone ever ringing. Tested from a desk phone, and sure enough it goes right to voice mail without ever ringing. If I make a call outbound from the Zenfone 6, it will always work. Then I'm able to receive calls for an unknown amount of time. I can reboot and get calls after the reboot, but they will eventually randomly stop.
SMS also come though delayed by hours. For instance someone sends a SMS my way at 2pm, I'll get it at about 4pm. If I send a SMS out bound, I then instantly get all the inbound ones.
Anyone know if I need to whitelist something in battery optimization? So far the Zenfone isn't really good at being a phone. - great at everything else though.
Check your apn settings I think I had to update the default to whatever BYOD APN settings are for T-mobile see if it helps you
Also had this issue on T-Mobile. If APN settings don't fix it, I'd go to Auto-start Manager in Settings > Battery > PowerMaster and allow your messaging apps to run.
For me, I'd get SMS messages only when my screen was on, and some weren't received from contacts, like it shuts the apps off after not using them.
Same here. I'm about to switch providers because of this. What rom are y'all using? I'm on LineageOS 16. @wreid23 can you post your APN settings?
Tried unoptimizing all the messaging related apps, no effect.

I've found the same to be true for me. Wi-Fi connection prevents calls from coming in. I can dial out just fine.
This is extremely strange since this phone is not even Wi-Fi calling certified and it's not even a feature. This has been my biggest issue with the phone so far because you never know if you miss a really important call.

Asus denies the phone could be the problem (despite the phone obviously being the only variable). I replied to that thread anyway, with my experience of similar lost calls on a Moto x4 with Wi-Fi calling enabled. Maybe it'll give some engineer at Asus a push in the right direction...
if any of you are rooted there is an alternative for now to enable volte and vowifi: https://forum.xda-developers.com/rog-phone-2/how-to/guide-enabling-volte-vowifi-v2-t4028073

I'm having the issue with T-Mobile 7T Pro, when I got the permanent unlock approval and switched to Mint Mobile sim is when calls went to voice mail, have you found a solution yet? Phone works fine if I use T-Mobile sim, but Mint Mobile sim in the 7T Pro is when the calls go to voice mail and text don't go out, if I put the Mint mobile sim into a Pixel XL all is fine. When I had to quit Mint Mobile becasue of this and go back to T-Mobile on prepaid again, all worked well.
The zenfone 6 is getting volte with the android 11 update so hopefully that fixes this issue
