How to Install and Use an Airalo eSIM
Step 1: Make Sure Your Phone is “Unlocked”
A locked phone has a software restriction applied by phone carriers that ties it to a specific carrier and prevents it from using SIM cards from other carriers. If you’re unsure if your phone is locked or unlocked, call your carrier’s customer service. Mention your military orders (as a CIVMAR, you will have them), and most carriers will unlock your phone for free. If your phone is locked, you will be unable to use any eSIM or SIM card.
Step 2: Make Sure Your Phone is e-SIM Compatible
Most new phones are eSIM compatible. Any iPhone newer than the iPhone SE (2020) will work. For a more expansive list, check the link below.
