Whenever I need a phone number, I always come here. If I'm in trouble, an AIS shop will help me. I sometimes find the identity verification process a hassle, but having a phone number makes it worth the price. What's more, if I go on two consecutive weekends, I can leave the eSIM as it is, and my phone number stays the same, and the price is even cheaper, so it's even more economical.
