Data's working. Calls and texts aren't.

I've just bought myself a second-hand O2 XDA Exec. I've unlocked it (thanks Buzz!), and everything was looking ok. In fact I'm typing this via my 3G connection. WiFi works well and the signal strength is great.
Unfortunately I can't make or receive phone calls. And I can't send or receive text messages either. All data services work perfectly, ActiveSync connects with my exchange server for Push mail etc, and the internet works perfectly with all 'connected' programs and pIE, etc.
When I do try to make a phone call, the dialler app just says "Dialling..." for a few seconds and then "Call Ended" There's never a dial/ring tone and when attempting to send a text message, I just get the notification: "Your message could not be sent". If I try to make a Video Call, I get a message to say that "Call Bars are active" despite the fact that my SIM works for video calls on other phones.
Have I bought a dodgy phone? Is this how a nicked phone behaves, or is there something else wrong with it? What baffles me is that I can use the net and use e-mail as much as I want, but phone calls are impossible. My T-Mobile SIM works in my other 3G phones, so I'm confused....I've tried various ROM's but they all behave the same way. Oh, and every time I turn the phone on, the STK server throws up a "Message Sent" dialogue. (Which I'm sure my old JasJar never did)
Help! Have I failed to sim-unlock this exec properly, is it nicked, or is it just knackered? I'll be off to the shop for a replacement soon, if I can't get this sorted out...

The first thing I'd try would be a hard reset. Don't know if there's another solution. Hopefully someone else will have another solution!

Tried that, and I've re-flashed with the latest Qtek and i-mate ROM's.
I think I'll have another go at "unlocking" the SIM cad, just to be sure, and I'll try another different ROM. But I think this'll end up being taken back for a refund unless anyone can give me some inspirational advice!

Since you say you've tried various ROMS, advising you to hard reset is pretty pointless.
The call and text behaviour you are getting is typical of a phone which is lost/stolen and barred. I always assumed that a barred phone would also not be able to use gprs & 3G. The wifi would still work though.
Are you able to use T-Mobiles data connection? What happens if you call the phone?

Nope, 3g networks defo don't check the imei register when you log on. ( Shhhh, the operators don't want you to know)
Dunno about a GPRS connection but it sounds like the handset is barred.
Richard

If I call the phone, a lady tells me that "calls are not being connected to this number at present". If I put the SIM into another phone, it instantly starts working again.
Tried a Vodafone SIM, same story. Also tried a Tesco mobile SIM (which piggybacks on the O2 network) and that's even worse, there's no recognition of any network at all when I put that one in.
I think this thing is going back to the shop at lunchtime...

Well, CheckMEND says that my IMEI has NOT been reported as lost or stolen, but I assume that's just for people who register and use www.immobilise.com rather than the network operator themselves?
I may give O2 a call to see what they say before I go shouting at the store that sold it to me, but I think that the only answer is that it's been blocked somehow. Hmmm. You'd think there would be an obvious way of finding out for sure...
EDIT: OK, O2 wouldn't tell me anything, it's confidential you see...
Took the phone back to the shop and they reckon the previous owner probably didn't pay is phone bill, so O2 barred the phone, therefore it wouldn't have been reported as lost/stolen. Which makes sense.
At least I now have my money back, and now I know that barred phones are only barred for voice calls, not Data connections too...never knew that!
Off to find another Universal to buy now...

Cannot send SMS in EDGE; WCDMA OK.

I can not send SMS when in GPRS/EDGE areas - receive is OK. When in WCDMA (3G) areas, SMS works fine. Has anyone else experienced this and perhaps found a solution?

Hi!
I also have problems with SMS sending. More or less with any network I am in. Usually I can only send one to two SMSes, then I need to reboot to be able to send/receive again. SMS just hangs for a moment in Outbox, then an error message is displayed, network connection drops and then reestablish, SMS is put in Draft. VERY annoying!
TomazL

Had the SMS sending problem (send 1 or 2, then had to reboot or rest went to drafts) when I first bought my phone e last year.
My problem? Old outdated SIM card. Went to dealer and they gave me a new one. Problem solved!

I did change SIM four times in the past 10 days. From the latest to the oldest my mobile operator has to offer. To no avail. Strange thing is that I have tested some SIM cards I could get my hand on (my father's for example) and two of them did not have this problem.
What could be the issue with SIM card? Why some are "outdated"?

Good question. I'm a pretty techy guy, but I know little about SIM cards.
I asked 5 techs who seem just as clueless. They said:
1. Newer SIM cards have More towers listed (doubtful)
2. Some SIM cards aren't compatible with 3G phones (maybe)
3. SIM contacts are dirty (no)
4. SIM might be overheating (no)
5. Some SIMs draw more current in certain network modes (doubtful)
I bet it IS your SIM. Ask if they have a 3G-compliant SIM. T-Mobile USA has no 3G yet but their SIMs are supposedly compatible. Who knows

Thanks for all the replies! I tried a friends new SIM and it doesn't work either, so I know it's not that. Re-booting doesn't help either. I am on the T-Mobile network and it works as soon as I am in their 3G area. It used to work on GSM until I upgraded to the official GPS update ROM and then it hung a few times and last week stopped sending altogether. It gives me a message that it is unable to send and moves the SMS to the drafts folder. Receive is OK. Is it possible that the radio (1.38) has become corrupted and maybe a new version (1.41) will solve this?

Re-booting only helps in sending one to two SMSes after reboot (and receiving queued ones). Otherwise I have just the same behaviour as you describe. I have also noticed that until I tap on OK on SMS error message, I am not available for incoming calls either! Do you also notice that after SMS error message network drops and reconnects? I have tried some friend's/family SIMs and majority did not work, two of them did. I don't know why. Where will 1.41 version of radio be available? Is it official?

I definately notice this problem as well. Always when the message is 2 SMS long... never can send. Perhaps it is the same problem as when the call is ended as soon as it is dialed, I read on one thread that the phone has trouble when switching to a 3g tower or not... I have a brand new ATT sim (cingular customer) in the Wash. DC area and I still have problems sending large SMS... sometimes reboot fixes but most times not... been searching also... I'm going to try to choose GSM only and vice versa to see if that makes any difference... the only other option for SMS is "Use unicode when necessary" does anyone know if that would fix?

I have now received fifth replacement SIM (looks like a very old and used one) from my mobile operator here in Slovenia, Europe. SMS sending and receiving now works like a charm! Strange that some SIMs work for no obvoius reason.

The phone has no problem switching between GSM and 3G (WCDMA) and in fact SMS works perfectly in 3G covered areas. I cannot send even a one word test, let alone a large message in my GSM area. I recently noticed that I can send SMS in some areas and not in others. Of course, I live in an area where I cannot send. What's weird is that it used to work. It may be that T-Mobile updated the network in some areas and that this is not compatible with Windows Mobile phones. My Sony Ericsson and Nokia phones still work. I'm hoping that when WM6 (official or at least Dopod) comes out, SMS will work properly again.

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 ??????

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...

Htc Touch Elf, calling problems

Here is the problem.
Altough i get full signal, i can't make/receive calls.
If i make a call it disconnects and i can hear a string sound (similat to a guitar).
If i receive a call the voicemail answers.
I cant make calls like *100# or any other stuff.
I changed the Radio, from 2.97.xx to 3.34.90 (or similar) then downgraded to 3.21.90
Is this a virus?
After i make a soft-reset i can make a call, but after 2-3 minutes, i can't make anymore.
Please help.
Btw, i'm using Orange.
Thanks in advance.

Please help

I'm also interested as to why you downgraded the radio? Did you get the issue on the 3.34 version? If not, can you not just put that back on?
I'd try hard reset before anything else like nnph said.
Stu

I had the same problem with an Orange SIM and the solution was simple.
I had a card SIM of 32k, I changed it for another 64k and problem solved.
Orange charged me 5 euros for the duplicate card, that's all.

in order to get to the bottom of this you should try:
1.if you consider the sim to be the problem: put the sim into another phone, see if that works
2.if you consider the phone to be the problem: try a hard reset! think if you had the problem before/after radio upgrade? if hard reset not working then try a different rom/radio.
If none of the above works for you than start to take into consideration a hardware problem, which I really doubt !!

Ironjon, did you had the exactly same problems?
I also have Cosmote, but it was doing that only when i had weak signal.
In other phone is working.
But i think it's sim's card fault. I only paid for the phone 25 E, it had broken speaker, i had someone to repair it for free. I'm not very upset if it not works, at least i can keept it for wi-fi and games.

Yes, I had the same problem.

Unable to Make/Receive Phone Calls

Wondering if anyone can point me in the right direction here. First off, I am an AT&T customer who is trying to get the DVP to work on their network. I bought an unlock code off of ebay (which seemed to work), but I cannot make/receive any phone calls. I can get Edge to work just fine and can make and receive text messages but all of my phone end almost as soon as I start them. And if I try to call the phone from my land line its immediately directed to voicemail.
On a side note, I have tried multiple AT&T sim cards and all have the same result. I also tried a co-workers tmobile sim and everything worked like a charm, so I know the phone isn't broken.
Any suggestions?

Can you try turning off 3G if its available as a option?

3G is an option but turning it on/off makes no difference on the phone side of things.
Could the unlock code that I received cause an issue like this? Is there anything in the EM app that could assist in what is going wrong? It makes no sense to me that I can send/receive text messages but I can't make phone calls.

Can u rest the phone and see if it helps?. Also try manually selecting the network.

The reset doesn't seem to help unfortunately. How do you go about manually selecting a network on the DVP? Is that in the EM app?

No, it should be as a option in the settings->cellular.
Does it even show the network that the device is current on?

It does show its on AT&T, but there is no option to change it I can see. I also configured the APN at the bottom to wap.cingular, but that didn't fix the phone issue.
BTW, appreciate your help on this! I am willing to try anything at this point.

Well, APN has nothing to do with Phone call. I think its just for text messages.
Ok..Here is how you do manual selection using AT command. Do this only if you are comfortable and don't blame me for any screw-up
Go to EM App->Protocol(password 6336#)->TMO->AT Command
No click the input field and type the following(at is automatically populated).
Manually search for the network:
AT+COPS=?
The above command will list all the available network. Once you do that, take a clear pic or write it down exactly and post it here. I will then give the formatted command to register it manually.

APN is for wireless internet access.

To be honest, I didn't even know that this was possible for the DVP yet. I've asked for unlock codes from T-Mobile every month that I've had the device (first attempt January 7th) to no avail.

Entered this in and it returned OK.
It did not enable us to make/receive calls though. It still acts like it's going to dial and just ends abruptly, and calls made to the phone still go straight to voicemail.
Also, just for fun I tried dialing using ATDT and a number and it returned NO CARRIER. Not sure if that will help narrow this down or anything.

I am facing the same issue. Using Unlocked Dell Venue Pro in India - worked wonderfully for a week, and then stopped making calls. my Problem is different. i can receive calls, send receive SMS and browse the internet (on 3G )as well. But Cant make outgoing calls.

Out of curiosity, those that have problems -
1. did u unlock using the AT command?
2. After unlocking, did u change/try changing sim cards (even if its from the same carrier)?

First off, thanks again for your help on this.
1. The unlock code was purchased from some website and when the AT&T SIM was inserted, it prompted for a code. So no, did not originally use the AT command. Is there a way to relock and try this process again?
2. Yeah, we tried a few different AT&T sim cards with the same result. We tried another T-Mobile sim and that worked perfectly.
