Why can't I get my sons texts?

My son has an android phone (not sure which brand) and I have an iPhone 5, I can't receive his texts, I used to be able to but a month or two ago I couldn t anymore, why would this be? My wife and daughter have the same phone as my son and I receive their texts just fine. Any thoughts I why all of a sudden I can't get my sons texts?

Your iMessaging settings need a lookin' at.

  • Why does my iPhone sometimes send texts to other iPhones as iMessages then regular texts to iPhones? Like when I send a text to my friend that has an iphone, it usually sends as an iMessage then it will randomly send as just a regular text and it will be green and not blue.
  • What do they sell at Frank and Sons? Is it like a swap meet with different types of booths? Or is it just strictly for anime merchandise? I was hoping to go there and look for a case for my iPhone. What types of things do they sell there?
  • My friend has complained her sons iphone got hacked and racked up a bill of £500,? Not sure how but apple have said that its past the 30 day period which you can challenge it and are threatening to send bailiffs over. They have been to citizens advice bureau and they say that if the contract says 30 days there's nothing they can do. Apparently it came from russia
