eSIM vs physical SIM card
Yes, you can buy a SIM card at San Francisco International Airport (SFO). SIM cards are available at TripTel in the Dianne Feinstein International Terminal on Level 2 of the Arrivals Lobby. They are open from 10:00 am to 8:00 pm every day.
Now, if you are considering getting an eSIM instead of a physical SIM card, here is some information to help you decide:
ESIMs, or embedded SIM cards, are digital versions of physical SIM cards that are built into newer smartphones and other devices like tablets, smartwatches, drones, and cars. They are programmed remotely via software, allowing users to switch carriers and plans without physically swapping SIM cards. This makes eSIMs convenient for managing multiple phone numbers on a single device and saves physical space, which can be beneficial for smaller devices like smartwatches. Additionally, eSIMs are less prone to physical damage or loss since they are built into the device's hardware.
However, one disadvantage of eSIMs is that not all carriers support this technology, which may limit options for users in certain regions or with specific service providers. There are also potential security concerns if the remote provisioning process is compromised, although these risks can be mitigated by strong security protocols.
On the other hand, physical SIM cards are small removable cards that are universally supported by almost all mobile carriers and devices, making them a reliable choice regardless of location or carrier. They are easy to transfer between devices, especially when travelling. However, physical SIM cards require manual insertion and removal, which can be cumbersome when switching carriers or managing multiple phone numbers. Additionally, losing or damaging a physical SIM card can lead to service disruption.
In summary, eSIMs offer convenience and flexibility in terms of carrier and plan changes, multiple phone numbers, and space-saving, while physical SIM cards have the advantage of widespread compatibility and ease of transfer between devices. The choice between the two depends on your specific needs and device compatibility.

ID requirements for buying a SIM card
When buying a SIM card at San Francisco Airport (SFO), you will need to provide a passport for identity verification. Airports may have stricter ID requirements than other stores, so it is always good to be prepared.
Some providers may also ask for a local address or phone number, so it is worth bearing this in mind.
If you are looking for an alternative to a physical SIM card, eSIM technology provides another option for connectivity. eSIM allows you to download a cellular plan directly to your smartphone without the need for a physical SIM card. eSIM retailers such as Gigago offer flexible local and multi-country plans with coverage in 190+ countries, ensuring smooth connectivity wherever you travel. However, smaller prepaid providers generally do not offer eSIM.
If you are looking to purchase a physical SIM card, you can do so at TripTel Mobile Services in the arrivals hall of the International Terminal. The store is open daily from 10:00 am to 8:00 pm. Alternatively, you can order a SIM card online and collect it at the airport or use an eSIM if your phone supports it.
