Block any unknown callers
Do you hate getting junk calls from telemarketers while you are in the middle of a meeting? Did you think it was impossible to block them because of the hidden number feature? You may believe this issue unsolvable, but actually, there is a way to get around unknown caller IDs. If you own an iPhone here is how to activate it.
Go to the settings app and tap on “Phone.” There you will find an option that reads “Silence Unknown Callers.” If you activate that there will be no chance of anyone bothering you during an important date or meeting. Well, anyone in your contacts can still call you, but in that case, you will know who to yell at later.
