I bought a SIM card with 5G internet for 1000, but the 5G only worked for a few days. I went to them at Central Phuket to ask why I only had 4G and why the internet was slow. They didn't give any explanation about the 5G; supposedly, the girl reset the SIM card, but nothing changed. In the end, I approached them about five times, and none of them helped me. AIS is the pits.
