Hi @elmacen ,
have you tried to reset the network settings of the phone?
Settings>general>reset>reset network settings.
after that check if you can now access that. If still not working you do have other options to use like the Gservices.
Here is the link:
Hope this helps,
So apparently, I cannot access the categories wherein I can create my own promo (screen interface) because everytime I dial *143# in my iPhone 4s which is recently upgraded into iOS7, the call ends all of a sudden. I tried dialing *143# for how many times and the same thing happens over and over again (call ends all of a sudden) Please help me know how I can access the promos easily without going online to check the promos and how to avail of it. Thank you. xx
Magandang Gabi Bayan!
Nang dahil sa iyong concern akong nagtanong sa kaibigan kong si Google kung ikaw lang ba ang nakakaranas ng ganyang problema, at ang sagot nya sa akin ay hindi laman ikaw at ito ay dahil sa pag-upgrade mo sa latest iOS.
Nabasa ko din na yung ibang carrier sa ibang bansa ay nag-issuing a carrier update, para malutas ang problemang ito.
