1. Introduction to Simyo
Simyo is a brand of Mobile Virtual Network Operators (MVNO) across Europe, co-founded with E-Plus in 2005, headquartered in Düsseldorf, Germany. The brand previously had a presence in France, Germany (now as Blau), and Belgium. Currently, it is owned by KPN in the Netherlands and by Orange España in Spain.

10. User Experience
The Simyo plan supports RCS and iMessage, but not VoLTE and Wi-Fi calling. It took me about 15 minutes to register the signal for the first time I activated the eSIM, and then I received a welcome text message informing me of the current tariff plan in my location.
If roaming in Taiwan, sending a text message costs about 0.5 euros. Using the balance of the number (12.5 euros), this number can be maintained for nearly 13 years, making it a very low-cost plan for maintaining a number, highly recommended for everyone to use!
