IMessage not connecting to new iPhone and mac?

Recently had my iMessage connected to both my iPhone and MacBook. I switched my iPhone 5 to a 5C today, and now my iMessage isn't connected interchangeably to both my new phone and my MacBook. Messages that I'm sending from my Mac aren't showing up on my new phone, but still my old phone. How do I go about changing that so they will show on my new phone opposed to my old phone?

Lol "APPLE" the company is not a fruit! Plus the iPhone 6 is just android.

On the new iPhone, choose "Settings" > iCloud. Click to sign out. Then sign in using the other Apple ID that you used before.

Apple can't prevent you from creating multiple Apple IDs. That's a pity, because most of those who create multiple IDs get totally confused.

  • Why is my iphone 4 (not an IOS) not connecting to my itunes 10.6? I've downloaded the latest version of itunes 5 times and every single time it says "the iphone can't be used because it requires iTunes version 10.5 or later". What to do? What to do?
  • Iphone and Ipad not connecting to my computer? Both my Iphone 4s and Ipad mini were bought this week. Trying to connect to my PC to sync my stuff. Neither are recognized by the computer and neither will charge. Doesn't show signs of any connection. I have connected them to my wall charger and they work fine. I have connected my mouse and webcam to the same usb ports that I have tried and they both work. Previously, I had a Itouch 4g on my itunes but lost it a few weeks ago. I have windows 7 home
  • Imessage not working, not delivering and turning green with certain number? So recently i went to bed and when i woke up I could no longer text this specific person. I thought they blocked me so i deleted the convo. I got an email from them asking i blocked them? I tried texting the messages turned green when she has an iphone and it wouldn't deliver. Hers wouldnt either. I've signed in and out of imessage but nothing worked so far. What's wrong with my phone?
