One month in Phuket - conclusion: works reliably!
I just spent one month in Phuket and I had 2 phones with me. I bought 2 eSIMs from Kalimi for Thailand and both worked absolutely fine. I had the 30-day 30 GB plan for my main phone and then a smaller data package plan with a local phone number (+66) on my second phone so I could register Grab with a local Thai phone number. I think it's great that they offer the option to get a local phone number as well. The speed was great. I sometimes achieved several hundred Mbps download. I will definitely use them again in the future.
