Best guide to activate eSIM on Google Fi Android and iPhone

eSIM, short for embedded SIM, is a technologically advanced form of SIM card that is built directly into devices such as smartphones, tablets, and wearables. Unlike physical SIM cards that require manual installation or switching, eSIMs are programmable and can be remotely activated by network operators. One major benefit of eSIM technology is its ability to provide users with the flexibility to switch between multiple mobile network operators without physically changing SIM cards. This means users can easily switch networks when traveling internationally or when seeking better service in different locations.

eSIMs eliminate the hassle of storing and handling physical SIM

What is an eSIM?

  • The embedded SIM, also known as the eSIM, is basically small, re-programmable built-in chip for your smartphone, tablet, or smartwatch. It’s used for similar purposes as what a physical SIM card does, but being carrier-independent it requires programming through software.
  • And with such handsets, converting to another provider is simpler still than buying and slotting in physical SIM card. Just get a configuration file and apply it to the device. This is typically what providers call an eSIM profile which they usually send you as a QR code to scan for download.

What are the benefits and disadvantage to using eSIM?

  • Theoretically, with eSIM, as many SIMs from multiple carriers as possible can be stored in your phone at once and switched among them. This allows you to change your plan of action within seconds on dozens of offerings — perfect when you’re roaming, for example, and need to grab yourself a short-term SIM from the country of your stay.
  • It is easy to test on multiple carriers as well. Many networks have free eSIM trial deals available for you to try the network out before signing up.

Which devices support eSIM?

  • While eSIM technology has been out there for awhile now, take-up to date is surprisingly slow amongst smartphone manufacturers. The reason for that is partially because most major international airlines did not adopt the new standard quickly enough. So, smartphone producers are proceeding to stay with it securely and incorporate the physical SIM space with eSIM ability.
  • In general, most you’ll expect this feature in high-end, flagship devices which are sold in top markets in the world, such as the United States, for instance, or the European Union. For example, Google and Apple both introduced eSIM back as early, since the pixel 2 of 2017 and iPhone XS for the second one. And Samsung caught up soon after — kind of; only for their expensive flagship phones like the Galaxy S or Note.

How to manually activate an eSIM on Android?

When you order an eSIM, your carrier will send you a QR code, which can be received either on their site or via an email.
