Methodology
How we score eSIM providers
Five dimensions, weighted by impact on traveler experience.
Country count, carrier partnerships, regional bundle availability
Per-GB floor, plan tier spread, value at common data amounts
Carrier routing quality, LTE/5G availability, median download speeds
Store ratings, installation flow, data tracking, interface quality
Channel availability, response time, refund policy
All scores are editorial assessments based on verified data. Pricing checked weekly. See our full scoring methodology for details.
HelloRoam -- Best Coverage + Value
HelloRoam installs on Galaxy phones through a web-based QR code flow rather than a dedicated Android app, working the same way on every eSIM-capable Galaxy model back to the S20. HelloRoam scores 8.6/10 overall with plans from $3.50/GB, undercutting Airalo and Saily for Galaxy owners who just need a second data line without an in-app dashboard.
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
- 63-language interface for non-English travelers
Cons
- Email-only support with 12-24 hour response times
- Newer brand (launched August 2025) with shorter track record
- App store ratings still building compared to Airalo
Airalo -- Best Overall Coverage
Airalo's app rates 4.8/5 on iOS and 4.6/5 on Android, the highest Android score among the five providers here, useful on a Galaxy phone since the app handles most of the setup friction rather than the OS. Its 200-country network and regional bundles suit a Galaxy S22 or newer running dual active eSIM across a multi-country trip.
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)
Holafly -- Best Unlimited Data
Holafly's Android app rates 4.2/5, behind Airalo and Saily, though its unlimited daily plans remove the need for the real-time usage tracking that matters more on a fixed-GB plan. A Galaxy S21 running Holafly as a second active eSIM keeps a home number reachable, provided that specific S21 unit is one of Samsung's US unlocked dual-eSIM models.
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 and activates its bundled VPN in the same interface used for eSIM setup, useful on a Galaxy phone connected to public WiFi before the eSIM activates. Its 150-country footprint and $3.99/GB fixed rate suit a Galaxy S22 through S25 owner running dual active eSIM on a defined itinerary.
Pros
- Backed by NordVPN parent company Nord Security with proven privacy infrastructure
- Integrated VPN protection included on every plan at no extra cost
- Clean, privacy-focused app with VPN toggle inside the eSIM interface
- 150 countries with strong European coverage
- 30-day refund policy
Cons
- Email-only support with no live chat or WhatsApp for urgent help
- Fixed data plans only; no unlimited daily tier
- 150 countries, a narrower footprint than Airalo
- 12-24 hour support response times
Nomad -- Best Budget Option
Nomad's Android app rates 4.0/5, the lowest of the five, and covers basic QR code installation without a runtime estimate or a dual-eSIM usage split. Its Southeast Asia pricing strength fits a Galaxy owner traveling that specific region rather than a broader multi-country trip across newer or older Galaxy models.
Pros
- Competitive pricing starting from $3.00/GB in Southeast Asia
- Simple, fast checkout with no account required in many cases
- Lowest per-GB rates for Thailand, Vietnam, South Korea, and Japan
- Plans start at a low entry price for short trips
Cons
- Email-only support with 24-48 hour response times
- Basic app compared to Airalo and Saily
- 112 countries, the narrowest footprint among the five providers
- Limited plan variety in some countries
FAQ
Frequently asked questions about eSIMs for Samsung
Which Samsung Galaxy models support eSIM?
Which Samsung Galaxy models support eSIM?
Every Galaxy S20 and later, every Galaxy Note 20, and every Galaxy Z Fold or Z Flip support eSIM. The S22 through S25 series and Z Fold or Z Flip from the 4th generation onward run two active eSIM profiles at once. The S20, S21, and Note 20 carry notes that narrow support on those three models specifically.
Which Galaxy phones run two active eSIM profiles at once?
Which Galaxy phones run two active eSIM profiles at once?
Galaxy S22, S23, S24, and S25 series phones, plus Galaxy Z Fold and Z Flip from the 4th generation onward, run two eSIM profiles active at the same time. The Galaxy S21 added this feature in 2021, but only on US unlocked units. The S20 and Note 20 support one eSIM at a time, in select markets only.
How do I check if my Samsung phone supports eSIM?
How do I check if my Samsung phone supports eSIM?
Open Settings, then Connections, then SIM Manager. If an Add eSIM option appears, the phone supports it. Dialing *#06# also displays an EID number when eSIM hardware is present. Confirming this before buying a plan from Airalo, HelloRoam, Holafly, Saily, or Nomad avoids a wasted purchase on an unsupported unit.
Does the Galaxy S21 support eSIM everywhere?
Does the Galaxy S21 support eSIM everywhere?
The Galaxy S21 supports eSIM, but Samsung limited its dual active eSIM feature to US unlocked models in 2021. S21 units sold through other regional channels may support only a single eSIM, so checking Settings, then Connections, then SIM Manager before a trip matters more on this specific model than on newer Galaxy phones.
Which eSIM provider is cheapest for a Samsung Galaxy?
Which eSIM provider is cheapest for a Samsung Galaxy?
HelloRoam and Nomad post the lowest starting rates in this comparison at $3.50/GB and $3.00/GB, both below Airalo's $4.50/GB and Saily's $3.99/GB. Holafly skips per-GB pricing with unlimited plans from $2.99/day. Pricing depends on provider and destination, not on which Galaxy model runs the eSIM.
Which eSIM app rates highest on Android for Galaxy phones?
Which eSIM app rates highest on Android for Galaxy phones?
Airalo's Android app rates 4.6/5, the highest of the five providers compared, with real-time usage tracking and hourly runtime estimates. Saily follows at 4.3/5 with a bundled VPN toggle. HelloRoam uses a web-based checkout instead of a dedicated app, working the same way across every eSIM-capable Galaxy model.
Does my Galaxy need to be unlocked for a travel eSIM?
Does my Galaxy need to be unlocked for a travel eSIM?
Yes. A carrier-locked Galaxy phone blocks eSIM installation from any of the five providers in this comparison, regardless of model or region. Galaxy phones bought unlocked directly from Samsung, or paid off under contract, typically qualify already, but confirm carrier-lock status before buying a travel eSIM plan.
