Find the best eSIM plan
in minutes.

An eSIM (embedded SIM) is a programmable digital SIM card permanently built into your smartphone's hardware, replacing the need for traditional physical SIM cards. Instead of inserting a plastic chip, you activate mobile service by scanning a QR code or using an app — your carrier profile downloads directly to the device in 30–90 seconds.

The technology uses eUICC (embedded Universal Integrated Circuit Card) chips that store multiple carrier profiles simultaneously, so you can keep your home number active while using a local data plan abroad. Key advantages for travelers include instant activation, dual-SIM capability, and cost savings of 40–70% compared to carrier roaming charges. Regional plans can cover 20–50+ countries without ever switching SIMs.

Most phones manufactured after 2020 are compatible, including iPhone XS/XR and later, Samsung Galaxy S20+, and Google Pixel 3a+. To check: dial *#06# — if a 32-digit EID appears, your phone supports eSIM.

Our AI analyzes over 15,000 eSIM plans from 120+ providers across 195 countries using a multi-factor scoring algorithm. It processes natural language input to extract your destination, duration, data needs, and budget — then runs four-stage scoring:

1. Query understanding — extracts key parameters from plain-English input
2. Multi-dimensional filtering — matches plans by country coverage, data size, validity, price, 5G, and tethering support
3. Value scoring — weights price efficiency (25%), provider reliability (20%), coverage quality (20%), plan flexibility (15%), features (10%), and activation speed (10%)
4. Contextual ranking — surfaces the best fit for your specific trip, with transparent tradeoff explanations

Provider data is refreshed every 6–24 hours from 120+ APIs, cross-referenced against 45,000+ user reviews and real-world coverage maps.

We sync pricing data with each provider's API on a rolling 6–24 hour cycle, so most prices are current within one day. Our index covers 15,000+ plans across 195+ countries. Because provider pricing can change without notice, we always link you directly to the provider's checkout page to confirm the final price before purchase.

We also maintain 18 months of pricing history, which lets us flag whether a plan is at its typical rate or currently discounted — helping you buy at the right time.

Yes — multi-country trips are where eSIMDB AI excels. Describe your full itinerary (e.g., "France, Italy, and Spain for 14 days") and the AI will automatically search for regional plans covering all your destinations in a single purchase, typically 20–40% cheaper than buying separate country plans.

It also compares regional options against the best combination of individual country plans, flags any coverage gaps, and handles mixed itineraries where one regional eSIM covers most of your route but a specific destination needs a local plan. For open-ended or unpredictable itineraries, global plans covering 100+ countries are also ranked.

eSIM is supported by approximately 78% of smartphones sold globally in 2025. Compatible devices include iPhone XS and later (all iPhone 11/12/13/14/15 series), Samsung Galaxy S20–S24, Galaxy Z Fold/Flip 3–5, Google Pixel 3/3a and all later models, plus select Huawei, Oppo, Xiaomi, and Motorola handsets.

To confirm eSIM on your specific device: dial *#06# — if a 32-digit EID code appears, eSIM is supported. Note: some phones sold in China, Hong Kong, and Macao have eSIM disabled by regulation, and some carriers lock eSIM functionality until the device is fully paid off.

Absolutely. WhatsApp identifies you by your registered phone number, not your active data connection — so your account and number stay exactly the same when you add a travel eSIM. Your phone operates in dual-SIM mode: the physical SIM keeps your home number active for calls and SMS, while the eSIM provides cheap local data.

Set the eSIM as your default mobile data line in phone settings. WhatsApp messages, media, and calls all route over the eSIM data connection at local rates, saving 80–95% versus international roaming. For example, sending 100 photos in Europe costs approximately €0.20–0.50 on a €10 eSIM plan, versus €15–30 via carrier roaming. Note: some budget eSIM plans block VoIP apps — always check for "VoIP allowed" in the plan details.

After choosing a plan from our AI recommendations, you're directed to the provider's site to complete your purchase. The provider sends you a QR code — typically within minutes. The full process: scan the QR code in your phone settings → profile downloads in 30–90 seconds → select the eSIM as your data source → you're connected. Total time: under 5 minutes.

We recommend activating 24–48 hours before your trip while still on WiFi. This lets you verify connectivity and contact provider support if any issues arise, rather than troubleshooting at the airport.

Approximately 60% of consumer eSIM plans restrict tethering, while premium plans typically allow it for an additional €3–10. Providers that allow full hotspot include Holafly Unlimited (most destinations), Airalo Regional plans (select packages), T-Mobile Prepaid eSIM (5GB hotspot, USA), and Nomad premium plans. Budget single-country plans from most providers block tethering entirely.

eSIMDB AI flags hotspot support clearly in every comparison result — look for the "Hotspot ✓" indicator. Before purchasing any plan for laptop or tablet use, confirm "Personal hotspot included" or "Tethering allowed" appears in the plan features, and avoid plans labeled "Personal use only."

Approximately 85% of eSIM providers offer zero refunds once a plan is activated. Once the profile is installed and connects to a network, it's considered used and non-refundable — this applies to Airalo, Holafly, Nomad, and most major providers. Limited refund windows exist before activation: Airalo (24 hours), Saily (72 hours), and Flexiroam (48 hours) all offer full refunds for uninstalled eSIMs.

Providers will typically issue credits or replacement eSIMs for verifiable technical failures: QR code won't scan, provider's network is down, or plan misrepresentation. To reduce risk: test activation 24–48 hours before departure, start with a small trial plan if you're trying a new provider, and document any errors with screenshots immediately.
