Hi, I set up my new iphone 6 three days ago, and my friends started voice calling me after, complaining that they are receiving messages from an email, and that I am not receiving their messages.
Since I still have my iphone 5s, I tested between the two phones several times, and found out that...:
When you set up a new iphone 6, it automatically asks you to login to your apple ID. When you do so, the imessage sending would default to your apple ID email address. Maybe this is the secure part where the messages do not pass through your carrier servers, and thus I think, will be more secure.
With a clear iphone 6 setup, I send an sms to another phone, and it arrives from my apple id.
But I wanted that my sms messages be sent from ONLY my phone number.
The steps above are the solution, but to be sure, I would add another step.
When you
Step 1: Turn off iMessage and mms
Step 2: Turn on the Airplane mode.
Step 3: reboot the phone
Step 4: Turn off the Airplane mode.
Step 5: Unlock pin sim
Step 6: Go to messages setting, turn on mms, and then turn on iMessage
Step 7: When you turn on iMessage, it will prompt you to use you apple id for iMessage, DO NOT TOUCH THIS
Step 8: make sure send as sms is turned on
Step 9: you will see your phone number next to the 'send and receive' click on it
Step 10: Make sure that under YOU CAN BE RECHED BY IMESSAGE there is only your phone number, and there is a check mark next to it.
For Facetime, go to Facetime settings and click on your apple id email address, and click logout
Step 1: Turn on airplane mode
Step 2: reboot phone
Step 3: Turn airplane mode off, enter SIM pin, and go to Facetime
Step 4:turn it on, and do NOT click on 'use your apple id foir Facetime'
JUST make sure that under the ( You can be reached by facetime at) option under, is your mobile phone number only , with a check mark next to it
this should work
