It doesn't mean anything, people who have my number are more than welcomed to text me any time of day, but it doesn't mean i'll respond or they're somewhat "special".0

He is Definitely Into you, @tessa8jo, and doesn't mind you pushing a button... Anytime of day or night.
Many of today's toms are Not the Best texters. This one May Not be as well, but has told you that you can 'Text him anytime' and I would imagine he will get back to you as quickly as he can, when He can, to let you know he is there.
However, on the other hand, the Message can go another way, where "Sure, NP with texting me anytime," and along with his other friends, he will get back to you when he can.
Good luck. xx0
