App issue solved quickly by support

Initially I couldn’t get the eSIM to load via the app, so I contacted support. They replied in under 10 minutes and gave me an updated app link. Worked perfectly after that. Impressive service.

Better than esim.me — way cheaper

I almost bought the esim.me adapter but it was over $60 with same specs! This one is so much more affordable and supports multiple profiles — I’ve already loaded 10 eSIMs with no problem. Super value.

eSIM installation was actually easy

Didn’t expect it to be this user-friendly. Just scan, install, and pop it into my Pixel 4a. No glitches. I also noticed their eSIM plans are cheaper than Holafly’s. Will use again.

Easy to Use, Even for Non-Techies

I’m not that tech-savvy, but installing the eSIM took less than 5 minutes. I used ChillaxSIM’s Japan plan and the adapter handled it without a hitch. Shipping to Sweden was ~$7.

Budget-Friendly and Works

Didn’t want to spend too much on an adapter. This one’s inexpensive but doesn’t feel cheap. Used it with a US eSIM on my old Moto phone. Shipping to NYC took 12days.

Pleasantly Surprised by Compatibility

Was expecting limitations, but I used a Holafly plan and later a ChillaxSIM plan without any issues. The adapter recognized both. No branding lock.

Good Performance, Fair Shipping Time

Took around 14 days to reach Italy, which is reasonable. The adapter looks basic but functions well. I’ve written 6 different eSIMs to it so far, all working.

Great Support and Simple Setup

Had one question during setup, and support responded within 20 minutes via email. Got it working right away on my iPhone XR. Works with non-ChillaxSIM eSIMs too.
