oops, am sorry chris
you are absolutely wright !
if the imessage option is turned on the iphone 4s and below , your friends will have the option to "send as sms" available.( i will correct that part of my post immidiately)
i am not sure if i explained it correctly, but the people that need to turn on the "send as sms" option are your friends who still own iphones and are trying to send you messages on the device you've switched to.
it's true that i am not an expert at this,
i am not claiming that this a general solution to the problem which is why i said that " it's an UNCONVENIANT way to get around this problem" on my post. this was actually suggested by another user earlier on this forum.
i did it, and it worked for me, so i decided to share with everyone just in case it works for someone else.
it's entirely up to you to follow my suggestion.
it seems like the worst that could happen is that your carrier will charge your friends according to their text message plan. ( not a 100% sure)
it's very unconveniant to call your friends and ask them to make sure that their "send as sms" option is on
but it works.
some users are saying that my suggestion is wrong. i am not sure why, but it worked for me
my advise is to call one of your close friends, and test it ( switch on "send as sms) and text you . if it fails, all they have to do is switch the "send as sms" option back to off .
here is the list of things i did before i came up to this:
1) turned off imessage on my iphone
2) called my carrier
3) removed my number from my apple account
4) called apple ( several times)
5) went to multiple forums
i never said to NOT turn off your imessage or to NOT call apple, i just said that it was useless ( based on my experience and apparently on several other users here too) if they had a solution, i wouldn't be here on page 29 of a post that seems to be going on for a while...
i am not involved in the apple love/hate fan war, we all have good qualities and flaws ( whether it's apple or me)
if i am wrong about something i always apologize, but if i am wright i stand my ground.
i never intend to offend anyone when i come to this post
and i will not engage in a conversation with angry users
good luck to all
