SJP's character and the rest of the SATC gang reference that their communications to Jones have gone unanswered.
Carrie heads to Paris to spread her late husband Mr Big's ashes, and makes an attempt to reach out to Samantha one last time - asking her to meet for cocktails.

As expected, fans went crazy over Twitter about the off-screen reunion between the two iconic characters.
"I'm glad Samantha got in the Eurostar for that cocktail - true friend right there," one fan wrote on Twitter.
A second wrote: "That sweet Samantha moment at the end ... I kinda want more."
Fans will be hoping for more than a digital communication between the two stars if And Just Like That is renewed for a second season.
It has sparked speculation Cattrall will be recast if new episodes are filmed.
But producer and director of the season Michael Patrick King has bluntly denied the rumours.
"No," he said in an interview with Variety.
"Just like there was no thought that Kim would ever participate in And Just Like That, because she's said what she had said."
He later added: "I have no realistic expectation of Kim Cattrall ever appearing again."
