You explained for yourself. But I can explain it to you if you need me to do so…
You went via the NT website. You had to use Google Translate in order to register and after you registered, you had to travel to the NT Wireless office to pick up the SIM. Quite different from your suggestion that it was just a simple fifteen minute journey to the TOT/NT Wireless office.
Whereas I told you at the time… order via Shopee, as they give a seven day money back guarantee. So you can test it and if it doesn’t work, you get your money back. No need for the ridiculous long winded palaver of what you did. Remember now? ???? But in the end, it’s nit a problem(at least for me) that you took the long way around. As in the end it turned out to be a good service for you.
