Double phone number in contacts
Dear apple community,
Im having a problem with my iphone, i have a lot of contact wich have two phone numbers. Lets say for example "John" has a phone number +31600000000 and 0600000000. I want to remove this and make it one phone number. Because im sending them sms messages and they receive it twice. Is there any tool or something that i can make them have one phone number?
I have alot of contacts and dont want to do this 1 by 1.
Help is greatly appreciated.
Greetings,
