A Boston e-sim has a few trade-offs worth knowing. Phones made before 2018 may not support eSIM technology, so check eSIM compatible phones before buying. Travel eSIMs are data-only and do not include traditional voice or SMS. An installed eSIM profile is tied to one device, though HelloRoam support can reissue it if you change phones. HelloRoam's multi-network access cuts most coverage gaps.

The main downside of eSIM is that you cannot physically move it to a different phone like a SIM card. An installed eSIM profile is tied to the device it was scanned on. You also need Wi-Fi or a data connection to download the eSIM profile the first time. For most travellers with eSIM compatible phones, instant QR code activation in under 2 minutes outweighs these limits by far.
