My iMessages aren't being delivered?

I have an iPhone 4 but it doesn't have a phone plan so I have to be connected to Wi-Fi to text. I was texting my friend to see if he wanted to go to the park and it said message not delivered. I sent another saying the same thing and it still says message not sent. I already reset my Wi-Fi.

Mine isn't working either, neither is my friends'.

Mine isn't working.problem with apple at the moment

Well that has totally happened to me but after i waited awhile maybe 5-10mins the did eventually get delivered

My messages aren't delivering

  • Why is my Iphone not sending as Imessages and receiving iMessages from one person? I'm texting my wife and we both have iPhone's and she is getting the messages as an iMessage but the ones I'm sending her on my end show up at green. Sometime it will go as blue, get the little red exclamation point then send as regular SMS. I'm texting someone else too and she has an iPhone, and she is getting mine as regular iMessages and mine are sending as regular iMessages. Why aren't they sending to me wife as iMessages?
  • Why aren't my iMessages in a blue bubble? Usually when iMessaging/texting somebody else with an iPhone, your messages are in a blue bubble. I have a friend who also has an iPhone, but when I text her my messages aren't in blue. Is there a reason for that?
  • Why aren't my emails being sent? On my hotmail, I can receive emails but when I send them I get a delivery failure email that the email can't be sent even if I'm sending the email to a valid address. I can't from my iPhone or even my laptop& pc. what's wrong with it? how do I get my emails to send. * I use hotmail to send emails. It's my main account. sorry if it's the wrong category, its the closest.
