Yesterday my girlfriends aunt texted me and today my girlfriend asked me why I have 2 numbers. I don't have 2 numbers. Apparently she (aunt) will text me but when I text back it shows up as a different number and not mine. How can this happen? I have no apps to change my number and I have nothing to hide so there is no need fir this but I don't like knowing somehow my number is changing. I have anever s7 and she has an unknown model i phone. And help would be appreciated
