The eSIM card is an embedded SIM card that, unlike the classic SIM card, cannot be replaced and is assigned to the corresponding smartphone or mobile phone.
The advantage of the eSIM card is that the card can be topped up at the end of the contract with the cheapest mobile phone provider. Whereby it can be assumed that the providers no longer work with mobile phone contracts. When using abroad, one can save on roaming charges and have the eSIM card activated with a low-cost provider. The same applies to Internet portals. Since the mobile phone and the eSIM card are fixed components, the mobile phone providers will offer mobile phones with integrated eSIM cards.
With the eSIM card, customers have greater freedom of choice and flexibility and are no longer contractually bound.
