Cannot make or receive calls

Hi,
I am using the O2 xda mini in India.
THe problem I am facing is I came to nepal for my vacation, and with the network service providers here, I cannot make or receive calls. The phone registers properly with the network. I can receive and send SMSs. THe only problem is with the calls.
I tried hard resetting the phone. I played with the call forwarding/waiting settings for a while and it started working BUT i wanted to copy number from the old sim, i inserted the old sim.. copied the numbers and inserted back the new sim again. And it has stopped working again. I tried hard resetting, playing with the settings. Can someone enlighten me on this.
PLEASE HELP ME WITH THIS.. CANT MAKE OR RECEIVE CALLS while I CAN SEND / RECEIVE SMS.
Thanx,
amit

Did you try inputting the international dialing code before the number?
If you are going to be in India for a while it might be best if you purchased a SIM chip there to go into your phone.
Also, your phone IS unlocked, right?

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...

Interesting Universal problem

Heh, I'm hoping someone on here will have some idea of what has gone wrong with my XDA Exec.
Just dragged it out of storage, unlocked it, upgraded the radio to 1.15 and the phone to WM6, but for some reason, it won't make or receive phone calls.
Now the phone picks up a signal (GSM & 3G) just fine with all the card's I've tried in it, and it will send a text message as well, but whenever you try to make a phone call, it disconnects the call.
Anyone got any idea's on what might be the problem here, and how I'd go about fixing it? Your help is much appreciated.

Are you on vodafone?

Personally I'm on t-mobile, but it shows the same behaviour with o2, Orange, T-Mobile and vodafone sim cards. I've tried em all, they all send text messages, but no phone calls can be made.
As I said - bizarre

have you confirmed that the text messages are actually being sent, i have seen a case similar and it turned out the IMEI numer was blocked

You know I never thought of that, but yeah I sent my other phone a text message and it went through. Sold it now, so not my problem, but an intersting problem.

[Q] lost calls and sms access still have APN

Hi folks,
I have lost access to phone and sms access from T-mobile uk on my unlocked SF.
I have tried the SIM on another handset, which worked fine and I have tried a different SIM in the SF handset but i'm having the same issue, so it seems to be a fault with the handset.
Has anone else had these issues? Did you find a solution?
Thanks
