1. even if it were a mobile phone there wouldn't be anyone else to talk to.
2. Even if another time traveller had a mobile phone there wouldn't be a satellite to route the call.
3. Even if there were a satellite there wouldn't be a network provider to handle it.
I find it difficult getting a signal now let alone in 1928 !!
GULLIBLE !!!

The one you're probably thinking of involves a jump sideways to a parallel universe where time is earlier. You don't actually go backwards in time, and it's not the same universe.

Essentially that you can go back in time but things like the Grandfather Paradox are not a problem.
If you try to go back and kill your grandfather before your father was concieved, or kill yourself before going back or whatever that you will fail to do so.
