eSIM is short for Embedded Subscriber Identity Module, or Embedded SIM. Rather than being available as a physical entity, the manufacturers integrate a small SIM card inside the phone, saving the process of switching between the physical ones when you change your service provider.
One of the biggest upsides to having your line stored within your iPhone’s eSIM is the freedom it gives you to switch carriers. In fact, this tech will make changing from one company to another as simple as switching Wi-Fi networks, giving you more power over the network which relies on your business to survive.
International roaming could be ‘eradicated’ within the next 3-5 years
The eSIM is very much the future for smartphones and smart devices. Even if you don’t have it now, it’s likely that your next phone—or certainly the one after—will make use of it.
The reason is embedded (electronic) SIM, more commonly referred to as eSIM. The research itself is not based on data that suggests this change will happen over this time span but instead is based on “confidential data” and the analysis of plans from 107 Mobile Network Operators (MNOs) from 92 different countries. A sample that the researcher state is the first international roaming-related eSIM global research project to take place. Based on the announced findings, the majority of MNOs were all in agreement that eSIM would likely put an end to international roaming once and for all.
