HelloRoam -- Highest Composite Score
HelloRoam scores 4.64/5 on our rubric overall for Galaxy S23, with App 5.0 and Support 5.0 on an iOS and Android app, live chat plus WhatsApp, and a 180-day refund. It installs on a Galaxy S23 through the Android app or a mobile-browser QR code, a process unaffected by the S23 generation's market-dependent dual-active-eSIM caveat since single-eSIM installation works the same everywhere. Plans price from $3.50/GB across 186 countries.

Pros
- 186 countries with 204+ carrier partnerships for reliable local routing

FAQ
Samsung Galaxy S23 eSIM questions, answered
Does the Samsung Galaxy S23 support eSIM?
Does the Samsung Galaxy S23 support eSIM?
Yes. The Galaxy S23, S23+, and S23 Ultra all support eSIM and Dual SIM Dual Standby. All five providers in this comparison, including HelloRoam at 4.64/5 on the rubric overall, activate on a carrier-unlocked Galaxy S23 through Samsung's native SIM Manager.
Can a Galaxy S23 run two eSIMs at the same time?
Can a Galaxy S23 run two eSIMs at the same time?
It depends on the carrier and market. Documented Samsung compatibility notes flag that the Galaxy S23+ (and the S23 generation more broadly) supports dual active eSIMs in select markets rather than universally, so a traveler should confirm this specific configuration works before depending on it. Running one eSIM alongside one physical SIM under Dual SIM Dual Standby is not affected by this caveat.
How do I add an eSIM to a Galaxy S23?
How do I add an eSIM to a Galaxy S23?
Open Settings > Connections > SIM Manager, tap Add eSIM, and scan the QR code from your chosen provider. Dial *#06# beforehand to confirm an EID number appears, which verifies eSIM capability.
Does a Galaxy S23 need to be unlocked for a travel eSIM?
Does a Galaxy S23 need to be unlocked for a travel eSIM?
Yes. A Galaxy S23 must be carrier-unlocked before any of the five providers in this comparison, HelloRoam, Airalo, Holafly, Saily, or Nomad, can install a profile. A locked device tied to a single carrier rejects third-party eSIM activation.
Which eSIM app rates highest on a Galaxy S23?
Which eSIM app rates highest on a Galaxy S23?
HelloRoam leads App at 5.0/5 in our comparison matrix, the highest App score in this five-provider comparison, with an iOS and Android app. Airalo follows at 4.7/5 on our rubric, with real-time data tracking. Saily scores 4.5/5 with a bundled VPN toggle.
