Asante, 30, who plays for Swedish side Rosengard, has 70 caps and featured at two World Cups and three European Championships.
Despite a call-up a year ago, her last appearance for England came in 2014.
“I don’t know why. That’s for him to answer. We haven’t really had much contact since last year, so that’s difficult,” Asante told BBC Sport.
“You want to maintain some level of communication but so far that hasn’t happened.”
The Football Association have said they do not comment on individual selection cases, but also confirmed that Asante featured in a behind-closed-doors friendly for England before last year’s World Cup.
England strikers Lianne Sanderson and Jodie Taylor, who play in the United States, are regularly picked by Sampson but Asante feels playing abroad may have affected her chances of a recall.
The former Arsenal and Chelsea defender also says that no-one from the England coaching staff has ever been out to Sweden to see her in action.
