What is Yesim?
Yesim is a Swiss digital eSIM service that keeps you connected in 200+ countries without ever swapping a physical SIM card. Founded in 2019 by Genesis Group AG (Baar, Switzerland; REG: CHE-135.623.633), Yesim has grown to 3.5 million users worldwide and consistently ranks as a Top-100 Travel App on both the App Store and Google Play, with a 4.7-star rating from 60,000+ reviews.
The core problem Yesim solves: your Irish or Indian carrier charges €5–€15 per day the moment you roam abroad. Alternatives — hunting for a local SIM kiosk, queueing at the airport, fumbling with a SIM ejector pin — waste time and money. Yesim eliminates all of that. You download one eSIM profile before leaving home, then buy destination-specific data plans from the app wherever you are in the world.
How Yesim Works — Setup in 4 Steps
Setting up Yesim takes under five minutes, requires no shop visit, no paperwork, and no SIM card ejection.
- Download the Yesim app from the Apple App Store or Google Play. Create an account — no KYC identity verification required.
- Choose your destination and plan. Pick a single-country plan, a regional bundle (Europe, Asia-Pacific, Caribbean, etc.), or activate Pay & Fly for automatic multi-country coverage.
- Pay and install. Tap "Install eSIM" — the profile is pushed directly to your phone's eSIM chip via the app. No QR code scanning is required (though QR is also supported).
- Activate when you land. Go to Mobile Data settings → enable the Yesim line → turn on Data Roaming → set Yesim as your internet line. Your original SIM stays active for WhatsApp and iMessage on your home number.
Plan Types: Standard, Unlimited Day Pass & Pay & Fly
Yesim offers three fundamentally different data plan structures, each suited to a different travel style.
Standard Plans — Fixed Data Bundles
Standard plans give a fixed data allowance (1 GB, 3 GB, 5 GB, or 10 GB) valid for up to 30 days, starting from around $1.28/day for popular destinations. These suit travellers who know roughly how much data they'll use and prefer predictable costs. You pick the country, pick the size, pay upfront, and the plan starts counting down from the moment you activate it.
Unlimited Day Pass — Annual Subscription
The Unlimited Day Pass is an annual subscription that gives you truly unlimited high-speed data on any day you're actually online — you pay for the year upfront but are only charged per active day, not per calendar day. A 7-day global block starts around $40. For frequent travellers making multiple international trips per year, the per-trip cost drops dramatically compared to buying individual plans each time.
Pay & Fly — True Pay-As-You-Go
Pay & Fly is Yesim's most distinctive product: a single plan that works automatically in 170+ countries, billing only for the exact megabytes you consume. You load a credit balance and the plan switches between countries as you travel — no per-country plan purchase needed. There are no per-day minimums and no wasted allowance for a short layover. Prices start at $0.54 for France. For travellers visiting multiple countries in a single trip, Pay & Fly is almost always cheaper than buying separate country bundles for each stop.
| Plan type | Best for | Price from | Countries | Speed cap? |
|---|---|---|---|---|
| Standard | Single-destination trip, predictable usage | ~$1.28/day | 150+ individual | No |
| Unlimited Day Pass | Frequent travellers, multiple trips/year | ~$40 / 7 days | Global | No |
| Pay & Fly | Multi-country trips, short layovers, PAYG | $0.54 (France) | 170+ auto-switch | No |
Virtual Phone Numbers — Your Private Second Line
Beyond data, Yesim offers virtual phone numbers: real, dedicated phone numbers from four countries that live entirely in the app, starting at $3.60/month, with no physical SIM required. You get a permanent second line to receive SMS and OTP verification codes for apps and services, without ever exposing your personal number.
Virtual numbers are available from:
- United States (+1) — from $3.60/month
- United Kingdom (+44) — from $3.60/month
- Netherlands (+31) — from $3.60/month
- Canada (+1) — from $3.60/month
Supported verification services include WhatsApp, Telegram, Google / Gmail, Instagram, TikTok, Facebook, Tinder, Apple / iCloud, PayPal, Amazon, Binance, Revolut, Signal, ChatGPT, and Claude — any service that sends an SMS OTP to a number you control.
This is especially useful for travellers and digital nomads who need a US or UK number for app registrations without revealing their home number, or who want a clean separation between personal and professional contacts.

Regional bundles are also available for: Europe (31 countries), Asia-Pacific, South America, Caribbean, Middle East, Africa, Central Asia, and a Global Pay & Fly plan covering 170+ countries automatically.
Pricing, Payments & the Ycoins Reward System
Yesim consistently prices at the affordable end of the travel eSIM market — standard plans start under $2/day for most popular European and Asian destinations, and the Ycoins loyalty system reduces costs further over time.
Payment Methods
Yesim accepts more payment methods than most rivals, including cryptocurrency — making it genuinely accessible worldwide. Accepted methods: Visa, Mastercard, American Express, PayPal, Apple Pay, Google Pay, and Binance Pay (cryptocurrency).
Ycoins — Earn on Every Purchase
Ycoins are Yesim's internal reward currency: you earn them on data plan purchases and from referring friends, then redeem them to pay for future plans. Refer a friend and you both receive €5; refer 5 friends and you earn an additional €50 bonus (up to €75 total per referral cycle). Ycoins balances display in your chosen currency (USD, EUR, GBP) and auto-convert if you switch.
Refund Guarantee
Yesim offers a 100% refund on unused plans purchased within 30 days, provided the plan has not been activated or used. This is notably more generous than most eSIM competitors, who offer no refunds once a plan is installed.
Device Compatibility — Does Your Phone Support eSIM?
Yesim works on any eSIM-compatible, carrier-unlocked smartphone or tablet — if you bought your phone outright or have had it unlocked, you're almost certainly good to go.
| Device | Supported models |
