Iphone 5 problems, please anyone?

For some reason every text I receive, my brother also receives them. We both have the iphone 5s and he only gets the messages from other people that have an iphone. Please can someone help, this is really irritating.

Thats happened to a person i know, but he said it was because of icloud. I don't really remember anything else but check with your carrier.

You will stop this by following this step
1.Go to setting. Tap messages

2.Enter your apple id & password. Tap sign in & next button

3.Tap send & receive. Edit addresses & remove your brothers one

Do you share the same iCloud account? If so, then thats the reason. You each need to have your own iCloud account. External (non-apple) texts can only be sent and received on the device that hosts it, but apple messages are shared across all devices.
