Airalo -- Best Overall Coverage
Airalo's app rates 4.6/5 on Android, the highest in this matrix, with real-time usage tracking through the same interface a Galaxy S23 owner would use on any Android device. Its $4.50/GB starting rate is the highest fixed price among the five, offset by the widest 200+ country footprint.
Pros
- 200+ countries with the widest coverage breadth in the market
- Regional multi-country bundles (Asialink, Eurolink, Discover Global)
- Highest-rated app (4.8/5 iOS, 4.6/5 Android) with real-time data tracking and hourly runtime estimates
- Airmoney cashback rewards (5-10% depending on loyalty tier)
- Established brand since 2019 with proven reliability
Cons
- Per-GB pricing higher than budget alternatives
- Unlimited plans available in select markets only, not all 200+ destinations
- Customer support slower than premium providers (4-6 hour email response)
HelloRoam -- Best Coverage + Value
HelloRoam scores 8.6/10 overall and installs on a Galaxy S23 through a mobile browser checkout and 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
- Fixed plans from $3.50/GB across popular destinations
- Unlimited plans from $5 for short stays, scaling by duration
- 31+ local currencies supported at checkout

- App store ratings still building compared to Airalo
Holafly -- Best Unlimited Data
Holafly's $2.99/day unlimited rate suits a Galaxy S23 owner who wants a single active profile without navigating the dual-eSIM market restrictions this generation carries. Its Android app rates 4.2/5, and its 1GB/day hotspot cap on select destinations applies the same as on any Android phone.
Pros
- Unlimited daily data from $2.99/day with no data caps
- 178+ countries covered including all major destinations
- Simple per-day pricing: know exactly what you pay before you leave
- 6-month refund policy on unused plans
- 24/7 chat support with fast response times
Cons
- Speeds reduce to 256 Kbps-1 Mbps after daily fair use threshold on most plans
- Hotspot tethering limited to 1 GB/day on select destinations
- Not cost-effective for light data users (under 3 GB/trip)
- Fewer countries than Airalo
Saily -- Best for Privacy
Saily's Android app rates 4.3/5, second only to Airalo's, and bundles NordVPN into every plan at no extra cost through the same app managing a Galaxy S23's eSIM. Fixed plans from $3.99/GB sit between HelloRoam and Airalo.
Pros
- Backed by NordVPN parent company Nord Security with proven privacy infrastructure
- Integrated VPN protection included on every plan at no extra cost

- 150 countries, a narrower footprint than Airalo
- 12-24 hour support response times
Nomad -- Best Budget Option
Nomad's $3.00/GB rate is the cheapest fixed price in the matrix, best matched to Southeast and East Asia routes. Its 4.0/5 Android app rating is the lowest of the five, with a basic interface and no real-time usage tracking.
Pros
- Competitive pricing starting from $3.00/GB in Southeast Asia
- Simple, fast checkout with no account required in many cases

FAQ
Frequently asked questions about eSIMs for Samsung Galaxy S23
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 8.6/10 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, Saily, Holafly, 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?
Airalo's app rates highest on Android in this matrix at 4.6/5, with real-time data tracking. Saily follows at 4.3/5 with a bundled VPN toggle. HelloRoam has no dedicated Android app and uses a mobile browser checkout instead.
