The Tottenham left-back almost missed out on last month's gathering at St George's Park because the FA had the wrong phone number for him.
Rose said: "I changed my phone number last year, and the lads were talking about the meeting and I didn't know anything about it.
"The day before, the people from FA texted me and asked me if I was coming, and I was like 'what meeting?'
"It was a big shock for me. For other players it might have just been a meeting, but for me it was a lot more. It shows I am maybe in the plans.
"I was over the moon to be included and I think I'm in their plans, at least a little bit. Even if it is a small part, it was a big bonus.
"I'm 25 now and not made an appearance yet for my country, but that's the aim for everybody. Hopefully I can keep playing well until the next time England meet."
