IPhone sends as text messages to other people?

I have iOS 7 and updated to the newest beta. When I send a message to someone who has an iphone it sends as a text. But when they send a text back it shows up as imessage and i can use imessage from there. Also when I send pictures it sends as texts, not imessage. What can I do to fix this?

Are you registered. This is a problem when people skip the activation process. Things go wrong with iMessage, FaceTime, and many other features around the activation screen. As well things could go wrong with FindMyiPhone and it can brick your device.

  • Why do iPhone messages come up as picture messages on other phones? When my friend sends me texts, she has an iphone, they come up as picture messages and i can't revieve them on my phone because my plan doesn't cover picture messages. Can she change the settings so it won't come up as a picture?
  • When Android user sends text to a mixed group of iPhone and Android users? A family member who is an Android user sent a text message to a large group of recipients, including me. The group has both Android users and iPhone users. I'm an iPhone user. Does this mean that I will receive everyone else s messages like an iMessage group, or will all messages go directly between the conversation starter and whoever is messaging him, without any of the other group members seeing what the other members said?
  • My iPhone 4 receives and sends text messages but can't send or receive photos? Barely bought a new iPhone 4, put my sim card into it and the iphone won't let me receive or send picture texts.

  • Is there any possible way I can schedule when a text message sends on iPhone 5? I want to send a text for someone to wake up to in the morning although if I send it now I think she'll still be awake whereas I don't want to sleep in tomorrow so its too late. Can I set it to send a message at about 4am? Or shall I just set my alarm to wake me up to send it?
