I always use SP Limousine to get to/from the airport. Nice cars, fairly easy to find in the airport. I get a small discount as a repeat client. Basic rate for a regular midsize car like a Camry is TBT 1150
There are a variety of eSIM providers out there. But I think most of them are data only. I have used Flexiroam many times. Good customer service. They have regional, country-specific, and worldwide plans. Airalo is pretty well reviewed but I have no experience with them. They seem to have much cheaper plans
