What do you mean, calls are restricted?

Call barring means that you can't call a certain number after setting a restricted number. For example, the mobile phone does not have the function of international direct dial long distance, and the telecommunication bureau will appear a voice prompt: "Call restriction, please do not use it beyond the authority."

When you call the other party, what comes in is: when your phone is broadcast in turn, the call is restricted, which means that your phone is set with call forwarding or interception function, which means it is blacklisted.

Call barring classification:

There are two types of call restrictions:

1, BAIC (all incoming calls are prohibited) When the user registers this service with the operator, anyone who calls the registered user will not receive the relevant incoming call notification. Cell phones can only make calls, not answer them. (I can only type, but I can't type) I can't receive text messages, but I can send text messages.

2. When roaming out of the HPLMN, all incoming calls are restricted (incoming calls are prohibited when roaming out of the PLMN country). During international roaming, you can only make calls, but you can't answer them.

In view of the relatively high telephone charges when roaming abroad, this service can be used when roaming outside the hplmn where the user is located to avoid the high cost caused by more incoming calls in roaming state. In addition, signing the service will not affect any incoming calls of users in hplmn. If the user is unwilling to answer the phone while roaming, he can use this service to restrict incoming calls.
