First of, No i dont know the number, and how come will my friend have it ?
in this scenario the phone is stolen, and my "pal" is not on the "send sms" list of new sim-card number OR i havent activated it..
and whats with the attitude ? you suppose to be some kind of admin and treating me like that ?
a "Guest" sign-in would NOT compromise security ? why would it ?
i would sign on my pals phone using the Avast-App, with E-mail and password and checking some "guest" mode,, that makes nothing be saved on his phone, and i can "locate other devices" and by login in as guest, it does not add the phone i´m loggin in on to my list of "phones" .. and then , when screen off it is sign-out or whatever..
even the slight security compromise by me having to type the password on another phone, on which i trust ofc, is not comparable to the critical moments right after a phone is stolen, i need to locate it fast.. otherwise it might be to late.
then back to the Q here,, how to send a locate request from a mobile, or even, how to know the number, when i dont have the sms function activated when the sim was changed..
