I have a brand new iPhone (first Apple phone) and I do not have 3G on it. I have turned on the 'Send as SMS' option in order to send messages as SMS when I am not connected to wifi, as did another iPhone user in order to see if that would solve the problem. I am able to send him text messages that way, however when he tries to text me his messages still go as iMessage even when I am not connected to wifi and thus I am unable to receive them. Is there any way to fix this issue without having him turn off iMessage? This is an issue I don't want to have to deal with everytime I text someone who is an iPhone user.
