LG smartphone Solution:-Go to the massage setting option - massage setting - give or" change sms center number correctly.

because you type incorrect adress.check the number & try again.it happens when you type a wrong code or wrong amount of digits.

..first revise the software you have installed and try to uninstall the latest software - you may be recognized that this problem appeared since you have instelled some software isnt it? If not then you have to hard reset your device (as ussually in such cases) - also described somewhere here.. (dont forget you will loose all your data):

1. Turn off the LG KS-20 completely (do this by pressing and holding the power button and wait for the prompt).
2. Press and hold these three buttons–volume down, Call and power–till the LED (this is beside the front camera) flashes.
3. Release the buttons. That same LED should flash blue/red/green and power up.
4. The KS20 should be in a clean state.

LG mobile phone KS20 review: this is probably the worst smart phone ever made. it does not sync with any PC operating system, it is unstable, it is getting too hot while chraging, the battery gave up after 18 months and above all: LG doesnt give ANY support for solving any of these problems.

i had the same problem, but i called my service provider (in my case, Vodafone) and they talked me through the settings. (they can also send u an sms which you download and gives you correct settings for PXT and to connect to the net.

To fix this problem is you need to borrow/own a phone that is from your service provider that isn't touch or 3G phone. I used Nokia 5200 or Nokia 5300.. Same phones

Change the number for Voice mail. (Your Cellphone Number) then put your Voice Mail # on your Text number where you receive your Text service SMS. Make sure both # has the +1 at the start.

Hope this help...

Another thing that helps is getting your text message and voicemail number. I requested it from T-Mobile since they are my service provider and have then shut down your network (phone off, battery out) after you are done.
(Settings - Phone- Services - Voice Mail and Text Messages - Get settings - then putting in the correct text messages service center number and voice mail)

It worked for me right away.
