The Samsung Blackjack wont make a call

Text services are controlled by your cellular service provider. Contact them and make sure that all of your text services are enabled.

If this helps please vote for my solution.

hi there,
call the customer service of your service provider ( AT&T,Vodafone,Verizon etc)....they will set up message center number on your phone , the one that you have might be incorrect...your mobile operator will send you sim updates that will refresh the settings ....and then you will get the text message options
cheers

If you want, you can try doing a hard reset, which will erase everything that's not on external storages. Here is the hard reset procedure:

1. Removing the battery without turning it off.
2. Reinstall the battery and turn the phone on with navigator key pressed down.
3. press any key to skip to prompt.
4. press yes to reset the phone.

Good luck.

goto call settings and click on call bar and applied to the calls on phone,click on message settings and wrong set the message number ,msg will not be able to send and received.

my did this. It is because your inbox or sent messages is full. you need to delete them. it might take a bunch of tries but it will work

What happens to the incoming calls? Check that you have not set the phone so that calls are diverted to voice mail or another number. Call your service provider and they will probably be able to send you a "service message" that will reset that.

i dont have a blackjack but this happened on my blackberry 8800. i just deleted a bunch of old text messages and it started working fine. i guess it was running out of memory and that was causing it to run slow.

i dont know if this will work for a blackjack.

I never used the text messaging on my blackjack,so I don't really know , but take a look at pages 121-123 of the manual.Follow this link to download the manual from Samsung.
