I'm confused. Got a text from SIL in America but it's from a uk mobile number.

I replied to it and she got the reply ok but it isn't her cell phone number. I've tried texting her on the number she gave me but she doesn't get them that way. Confused Do the messages go to a message centre or something?

maybe she borrowed some one elses mobile.

Hi, no it's her mobile. We were chatting on Facebook at the same time while we were trying to work out how to text eachother.
