I bought a lucky SIM card. Do I still need to buy an entry and exit package?

"Yes, when I was traveling in Thailand, I met many locals, made many friends and left each other's phone numbers. During the trip, I also asked them many questions through SMS. Because I use AIS lucky SIM card, I send messages to local numbers, each of which is only 3 baht, less than 10 cent.
