    samsung note 2 korea *143# ussd code running then umb11 error. please help!


      Hi everyone!  


      I hope you can spare some time to help me with my access.   I just got a hand me down samsung note 2 model number SHV-E250k with android version 4.1.2. I hope to upgrade to kitkat soon. I believe that this model is originally sold in korea.  


      I am finding a hard time registering to promos in *143#. Whenever i dial *143#, then press dial, it says "ussd code running" it stays that way for some time then says "umb11: service unavailable, please try again later."  


      I hope that there are just some settings that i can just tweak. The previous user of this phone is a smart subscriber. 


      I will greatly appreciate any effort from anyone. I hope someone in this community can make me understand what umb11 is. And in case this phone cannot really dial *143# (i hope not), is there an alternative way to register to promos? Help me please....
