Last time I bought an e-SIM at a higher price, I didn’t see any difference, the connection is great, the connection is elementary, instructions are provided.

Easy to install. Convenient to use. Good signal. Works well even in many places. There is a link to check how much you have used. Recommended. No need to put in a SIM card, it's a hassle.

Excellent eSIM, bought for a trip to Malaysia, Singapore, and Thailand. It has a signal everywhere, including 5G, so you can share the internet. The internet works better than hotel Wi-Fi.
