What is an eSIM and how does it work?

An eSIM (embedded SIM) is a digital SIM built into your phone. Instead of swapping physical SIM cards, you scan a QR code to activate a data plan instantly. Your phone connects to a local network in your destination country, giving you fast data without roaming fees.

It activated quickly. I connected without any issues after receiving the QR code in a matter of minutes. The ability to pay with cryptocurrencies was also appreciated; the entire process went well. I had no trouble staying connected during my journey because of it. For hassle-free internet access, BitJoy is a great option if you're planning a trip soon!

The activation process is not complicated, and it was done quickly by following the steps. The payment method is also flexible. I tried credit card and cryptocurrency payment, and both were completed smoothly, and the payment was immediate. When I arrived at the local area, I scanned the code to connect to the Internet, which is very convenient and very suitable for travel.

I'm giving 4 stars because the installation guide didn't mention that I had to set up the APN manually, and support also didn't immediately suggest it. I had to do some troubleshooting myself. Other than that, so far so good. P.S. I used it in Turkey and the APN is 'isp.'

Activation is simple, and payment supports multiple methods, including cryptocurrency, and the operation is very smooth.
