we both have 6 Plus; all of a sudden (after working for the first week or so he had his phone- his came after mine) my texts to him are showing as only choice being a non-iphone (SMS?) text. We have checked that we both have our phone numbers checked off as iPhones and they are. My other friend's phone number comes up as iMessage just fine. Any ideas on things I haven't checked? I talked to tech support twice and they told me to do some things which didn't help (put a 1 before the phone number, turn on wi-fi), both things I never had to do before and don't have to do for my other friend's phone. Hers is a 4s if that makes any difference. Frustrated.
TIA
