There's no way that you could have done what you said you have done!
Call baring is available for calls from certain chosen numbers, only, and only a few of those too.
To put it in place for any number, there's a code that must be dialed to achieve this, and another code that unblocks that number.
Please do not get confused with the "PUCK", unlock code!
It sounds to me as if your phone is now locked, and you will have to use the unique "PUCK" code to unlock it.
If this does not work, after three, only, tries, then your phone might have become useless.
But, you can try the professional unlock services, first, before you throw the phone away.

  • Will it show up as a missed call if i call someone by accident for half a ring? So I accidentally called my ex on his iphone, but I quickly realized my mistake and hung up after a half ring. Like you know how when you're calling someone it rings, I hung up after the first riiiing. My question is, will it show up on his phone as a missed call? I tested it out on 2 friends. One iphone 5 and iphone 4. They both told me they didn't get a call. Am I in the clear?
  • IPhone 6s Plus, how do you mute a call while on call? (not how to mute ringer)? I have a new iPhone 6s Plus and need to listen in on conference calls without other people on the call hearing me type in the background or the kids, so how do I Mute the sounds on my end so I can listen in without disturbing the others on the call? My current phone keypad on the iPhone 6s Plus only shows 1-9,0 *, and # buttons.
  • If you remove the Passcode on a iPhone 4 will the Find My iPhone app still work? I lost my iPhone 4 on Saturday & I switched of the cellular data before I lost it & the Phone has a Passcode, Can the Person who stole my phone unlock the Phone in Namibia & will I still be able to locate if he removes the Passcode. I don't have the serial # My dad brought it from Germany without a box. & I tried Locating & Locking it but its currently offline
