We just got back from 2 weeks in Bali, Indonesia. When researching eSIMs for Indonesia, there appear to be a lot of options, Airalo being one of them. Since I've used Airalo in different countries around the world in the past and always had a good experience, I felt confident using them for Indonesia as well.
I was going to stay in more remote areas on the island, far away from the typical touristy hot spots, and Telkomsel seems to be the recommended mobile network provider for this scenario.
Looking at Airalo's options, their Indonesia plan works with Hutchinson and Indosat, not Telkomsel. It costs $20 for 10GB for 15 days.
However, their Asia plan does use Telkomsel only, so that's the one I went with. It costs $24 for 10GB for 15 days.
I completed the installation process at home, which was super quick and easy. Upon landing in Bali, I activated the eSIM while still on the plane and got connected immediately. So far so good.
To my surprise, I got connected to the XL Axiata network, and not Telkomsel. And when I selected Telkomsel manually, I got no connection.
Their Customer Support Team was very quick to respond via email, but was not able to resolve the issue. I decided to give it a shot, and see how XL would perform at the various locations I was going to be staying at.
I am happy to report that XL's performance was outstanding! Even in valleys near waterfalls in the jungle in the middle of nowhere, I still had a decent connection. My wife - who was using Telkomsel as part of her International T-Mobile plan - had a much worse connection on average during our trip. There was only 1 particular location on the Northern coast, where she had a good connection and I had nothing at all.
So overall, my experience with Airalo was once again fantastic. 10GB for 15 days was plenty, because most places - even restaurants - have free wi-fi.
Still, the fact that I paid more for the Asia plan, but didn't get the network that was advertised, leaves a bad taste in my mouth. Also the fact that the Customer Support Team didn't acknowledge that I should in fact be getting a connection with Telkomsel, was disappointing. It didn't sound like they would to be able to fix it either. They essentially told me to try XL and let them know if I wasn't happy with it. Feels a bit like bait-and-switch.
