I bought an eSim for my 21 day vacation, it was a 30gb data plan. 4 days in my vacation and after using only 3.5gb the eSim stopped working out of nowhere. I sent an email to customer service, a message on their app and I tried to contact them any way possible. They take more than 24h hours sometimes 48 hours to answer back to their email. I even answered back to one of their emails 2 mins after they sent one to me and they took 24+ hours to answer back. After 5 days of waiting for them to fix the issue I had to buy another eSim from another company because I needed data to travel. They never figured out the issue and they never want to give me a refund. This was the worst customer service I ever experience! The eSim from AirHub didn't worked for the rest of the trip. NEVER BUY A eSIM FROM AIRHUB!! This is a scam!
