My IPhone 3g had been telling me 'Message Send Failure?

When i try sending a photo, it shows "message send failure" i've sent photos before and this is the first time its showed this sign. Is there anything i can do to fix this?

Wi-fi problem

Make sure that you have signal, most likely this is a sign that your service has been interrupted while the photo or information was trying to be sent. Once you correct this everything should run smoothly. BEST OF LUCK!

And Bye.

  • Why won't my 5c send a message as MMS when it's a long message to a non iPhone user? Whenever I type a LONG message to an SMS user (says Text Message in the messaging "box") my 5c won't convert to MMS and the recipient gets the message in dozens of out of order messages instead of the whole fluid message. I have MMS on in Settings. What can I do and why is it doing this?
  • What does message send failure mean on iPhone? I sent this person a iMessage and it didn't go through and said "message send failure". I've texted this person before and had no problems but now it's saying this. The person I'm texting also has an iPhone. What does "message send failure" mean? Could it mean that there phone is off?

  • Message send failure on iPhone 5? Every time I try to send a picture through iMessage I get "message send failure". But all of the pictures I send go through and get delivered to the receiver. Yet I keep getting that message even though it sent. Does anyone know how to fix this? It's been going on for a couple of days now.
