There is no definitive time frame on it.
Giving your number out to a guy may mean that he will contact you that very day, the next or even in another month from that day.
Yes, a month isn’t that unusual.
He may never even use the number.
You really shouldn’t sit by your phone or hang on to that smartphone for dear life just waiting for his call or text.
For most guys, the likelihood of them calling you may depend on what stage in life they are in and how well their interaction went with you.
If you both had a great conversation or there was strong mutual attraction, you may hear from him in a day to three days.
This is because the effect that you had on him is still fresh in his mind and he wants to experience it again.
He wants to go back to that source that made him feel good.
Other guys have a one week rule.
They have been taught that they need to give it about a week before they text a girl so as not to appear too desperate and to have her wanting.
Well, this is not the best rule but a number of guys do go by it.
Then there is the guy who doesn’t contact you for weeks, you have probably moved on believing that he wasn’t interested and all of a sudden he sends you a text out of nowhere.
Why did he take 3 weeks or more to send you this text?
Well, a guy who takes this long to contact you typically does because you weren’t a priority in his life.
He may have already been seeing someone at the time that he got your number.
There are some guys who actually may still have a girlfriend when they get a girl’s number. However, they would get that number for a number of reasons.
They may have had an argument or some kind of rift with their girlfriend.
Perhaps they were in a period when they were giving each other space.
This argument may have led to a number of days of no contact with their girlfriend.
They may also have felt that the relationship seemed to be on its way to a close and they might as well start talking to new girls and collecting phone numbers.
These are some of the more popular reasons why a guy would take that long to text you after having taken your number.
There was typically someone else in the picture and oftentimes that person may have been a girlfriend.
However, a few weeks to a month has passed and perhaps that relationship has now died.
As a result, they decide to text you.
It never feels particularly good to be the one that they fall back on.
Most people don’t want to be the next best thing by default.
They like it when they are the number one choice.
However, this is a reason why this guy may take that long to text you.
Then there are the guys who end up never texting.
This typically happens when the guy had no real interest in the first place.
If you notice that you were the one who was pushing most of the conversation when you were interacting with the guy and he was basically reacting without contributing too much, this would be the prime candidate who would never text you after the fact.
