FAQ

Q: Why is eSIM not popular? 

A: Anything that’s new takes time to gain traction. But as more network providers and manufacturers continue to adopt eSIM technology, they are likely to become more popular.  For traveling, this will, and already has slowly started to revolutionize the market. Also, the fact that not all devices support eSIM at the moment also limits its usage, but this is also expected to change soon. 

Q: Does eSIM change your number?

A: Nope! Using an eSIM instead of your regular physical SIM card will not automatically change or alter your phone number, even if you are abroad. If you would like to change your phone number, you would have to get in touch with your mobile network provider to see how that can be done.

A:   For international travel, eSIM offers more convenience than physical SIM cards. It removes the need to go purchase a card every time you travel to a different country. You can easily  switch between plans and network with very minimal effort or time invested. Traditional SIM cards do still have their benefits, mainly being their widespread compatibility with networks and devices.  At the end of the day, it really depends on the device you need and whether or not you are traveling.
