IPhone 4 iMessaging problems. AT&T?

I have an iPhone 4, 16gb (that doesn't mean anything but I guess I'll put it there anyway)

It's on AT&T and I swapped the SIM card from my old Android phone.

About one tenth of my texts fail to send- ONLY iMessages! I have a texting plan but I live in a wealthy place so everyone has iPhones, so I basically use iMessage the entire time.

I click send and it zooms up to the end of the loading bar and stops. Usually it just takes a minute to send but sometimes fails to send.

I always have 3-5bars on AT&T of 3G.

What's the problem?

Take your phone and the issue you posted on here to an at&t store and they can fix that for you! DUH!

  • Switched from iphone to galaxy s3 and I'm having issues with imessaging? All my friends with iphones are having issues texting me. I don't know what to do. I know it's because of imessage. If I turn that off on my end (My old phone and my ipad) will that fix it?
  • Is imessaging with iPhones free? I'm in Korea using only Wi-Fi and want to text my friend in the US who uses Wi-Fi and 3G. Would imessaging be free? Even if one is on Wi-Fi and one is on 3G?
  • Is iMessaging internationally free? Quick question, i have an ipod touch and an iphone 5s, living in the UK. My friend has an ipod touch too and an iphone 5 living in america. They have imessage activated on their ipod, i have it activated on my phone as i rarely use my ipod. Summary: will it be free for me to imessage them from my iphone 5s in england to their ipod touch in usa?
  • Is data used when Imessaging with the iphone? I only get a certain amount of RAM a month, does Imessaging use data? I turned off my data since i'm on Wi-Fi, but then the imessages do not sent? Do they use alot of data? Just got my iphone yesterday, so i'm slowly learning haha.
