Understanding eSIMs and Unlimited Data Plans
What is an eSIM?
An eSIM, or embedded SIM, is a digital SIM card that allows you to connect to a mobile network without the need for a physical SIM card. This is particularly convenient for travelers, as it means you can switch between networks and plans without the hassle of changing physical cards.
What is Unlimited Data?
When it comes to eSIM plans, "unlimited" often means a daily high-speed cap, after which your data speed may be throttled. This is known as a Fair Usage Policy (FUP). It's important to understand these terms to avoid unexpected charges.
