Text Messages 'unidentified subscriber'?

Hi - am loving most things about my new Blackberry but the texting is proving to be a little glitchy. I receive texts but it comes up with 'unidentified subscriber' when I try to reply and messages have a red cross by them and will not send.


This is coming and going - typically I went into tech support shop day after I had gone online and it all seemed fine, but now has gone this way again? Any ideas?

Re: Text Messages 'unidentified subscriber'?


I think you can try two things : the soft reboot, and if it does not work, the hard reboot. Don't worry, you can't lose data with these two reboots.

Soft reboot :
1) Hit the three following keys at the same time :
- Alt
- Right Shift
- Delete
2) wait 2 minutes for the Blackberry to wake up.

Hard reboot :
1) your Blackberry device is on
2) remove the battery and wait for a minute
3) Put the battery back
4) wait 5 minutes for the device to wake up.

Please tell us if it works for you.

Re: Text Messages 'unidentified subscriber'?

I just bought a 9780 today (in the UK) and have the same problem... can't text (sms) anyone. but have no problem making calls to those same numbers.

I tried the reboots mentioned above.  Still no joy.

Any ideas?

Re: Text Messages 'unidentified subscriber'?

I have the same problem with one number in my phone. Yesterday no problems, today I get the Unidentified Subscriber message. I tried calling the number and there was a voice message saying "the number you dialled is not recognised". Anyone have any ideas?

Re: Text Messages 'unidentified subscriber'?

I solved the problem for BB 9930.
He was the card or the provider settings.
So the problem was that the simulation has lost no phone message center.
Remove the SIM from BB and put it in another phone with the option to message center.
There set on your SIM card's phone number message center, save then restart the phone. Check on that phone if you can send SMS, sure you can.
Remove the SIM card and reinsert it into your phone BB 9930.
Will work.
