Yesim highlights
App-first experience
A polished iOS and Android app: purchase, QR-code installation, remaining-data tracking and top-up from a single account, with several eSIMs managed in parallel.
200+ destinations
Broad coverage across the five continents through hundreds of partner operators. Country, regional and global plans for multi-country trips.
Unlimited Unlim Day Pass
On top of the fixed-volume plans, Yesim offers unlimited passes billed by the day: handy for trips where usage is hard to predict.
SwitchLess Networks
The phone switches automatically to the best-performing 4G/5G antenna available locally, with no manual steps, which limits dead zones.
Tethering
Hotspot is allowed on most Yesim plans: you can connect a laptop or a tablet to the eSIM's data.
Top-up without reinstalling
Top up an existing Yesim plan from the app without scanning a new eSIM: useful for extending a trip at the last minute.
Who is Yesim? A look at the operator
Yesim is a travel eSIM provider with an app-first positioning: the mobile app is the heart of the service, where many MVNOs rely on a website. Like the whole sector, Yesim does not own its network: the brand resells access to local partner operators (several hundred announced) under a unified technical layer, which explains coverage of 200+ destinations and the variability of 4G/5G speeds from one country to another.
The technical highlight the brand puts forward is "SwitchLess Networks": instead of staying locked to a single carrier, the phone switches automatically to the best-performing antenna available on site. In the field, this mostly translates into better service continuity in areas where a single operator has poor coverage, an asset appreciated by digital nomads who change location often.
On the plans side, Yesim distinguishes two main families: standard fixed-volume plans (expressed in GB for a duration in days) and the Unlim Day Pass, unlimited data billed by the day with fair use. This per-day format is easier to read than a monthly plan for short stays, but you need to watch the number of days to stay competitive against a simple GB plan.
Yesim eSIMs are data only: no real phone line or number to receive calls on the mobile network. Voice goes through the usual apps (WhatsApp, FaceTime, Signal). Tethering is allowed on most plans, and top-up is done from the app without reinstalling an eSIM.
Is Yesim reliable? The service relies on recognised operators and a standard refund policy: full refund as long as the eSIM has not been activated, case-by-case review for a proven malfunction after activation. Points to watch: speeds that vary by partner, no phone number, and on the Unlim Day Pass a fair use that can temporarily reduce speed after very heavy usage. Trustpilot and app-store reviews stay broadly positive on the app's ergonomics.

Recurring strengths
- A complete, well-rated mobile app: purchase, installation and data tracking in one place
- SwitchLess Networks: automatic switching to the best available 4G/5G antenna
- Unlim Day Pass by the day, handy when usage is hard to estimate
- Top-up and management of several eSIMs from a single account
Points to watch
- Data-only plans: no phone number to receive network calls
- Speeds vary by destination and local partner (5G possible, 4G or 3G elsewhere)
- Unlim Day Pass: fair use that can reduce speed after very heavy usage
- China: a VPN installed before departure remains necessary for Google, WhatsApp and Instagram
Our analysis: Yesim is a relevant choice for travellers comfortable with 100% app-based management who want an unlimited pass billed by the day. For a very short stay with moderate usage, a simple GB plan from Airalo or Nomad can work out cheaper; for heavy streaming on a long stay, Holafly's unlimited data often remains a better fit.
Yesim coverage: where do the plans work?
Yesim offers plans in 200+ destinations, in three formats: single country, regional and global. Here are the destinations most searched by travellers, with a direct link to the matching Yesim plans.
Popular destinations covered
⚠️ A warning for China
China blocks Google, WhatsApp, Instagram, Facebook, YouTube and much of the Western web (the Great Firewall). The Yesim eSIM for China relies on a local operator, so the blocking applies. To reach your usual services, install a VPN before you leave (NordVPN, ExpressVPN, ProtonVPN, Mullvad): once you arrive in China, the VPN download sites are themselves blocked.
Yesim plan types
Country plan
An eSIM dedicated to a single destination, in a fixed volume for a duration in days. Ideal for a focused trip (Japan, United States, Thailand).
Regional plan
A single eSIM covering several neighbouring countries. Handy for a multi-country itinerary without changing eSIM along the way.
Unlim Day Pass
Unlimited data billed by the day with fair use, on eligible destinations. A readable format for stays where you don't want to count your GB.
Global plan
An eSIM that follows the traveller from one country to the next thanks to automatic switching between partners. Designed for round-the-world trips and digital nomads.
Yesim FAQ
How do I activate a Yesim eSIM?▾
Installation is done from the Yesim app or via a QR code emailed after payment. iPhone: Settings → Cellular → Add eSIM → scan the QR. Android: Settings → Network & internet → SIM → Download a SIM, or guided installation from the app. Activation takes effect on the first connection to the foreign network: do not activate before you land, to preserve validity.
What is the difference between a standard plan and a Yesim Unlim Day Pass?▾
A standard plan gives you a fixed volume in GB for a duration in days. The Unlim Day Pass offers unlimited data billed by the day, with fair use: useful when usage is hard to predict. For moderate usage over few days, a GB plan often works out cheaper; compare the two on Datadopt for your stay.
Is there a Yesim app?▾
Yes, and it is the heart of the service: the Yesim iOS and Android app lets you buy a plan, install the eSIM, track remaining usage, top up without reinstalling an eSIM and manage several eSIMs from one account.
Does Yesim work in China?▾
Yes, China is covered, but Google, WhatsApp, Instagram, Facebook and YouTube are blocked by the Great Firewall even via Yesim. Install a VPN (NordVPN, ExpressVPN, Mullvad) on your phone BEFORE you leave: once you are there, the VPN download sites are themselves blocked.
Can I use WhatsApp, TikTok and tethering with Yesim?▾
WhatsApp and TikTok: yes, on every destination (except China without a VPN). Tethering (hotspot): allowed on most Yesim plans, so you can connect a laptop or a tablet to the eSIM's data.
Do Yesim eSIMs have a phone number?▾
No, Yesim plans are data only: no number to receive calls or texts on the mobile network. You keep your usual number on your main SIM (dual SIM) and make your calls via WhatsApp, FaceTime or Signal.
Does Yesim refund if there is a problem?▾
Full refund as long as the eSIM has not been activated. After activation: case-by-case review for a proven malfunction, not for simple usage. Always test the data before relying on it heavily, and contact support through the app.
Yesim or Airalo: which one to choose?▾
Yesim = an app-first experience, automatic switching between antennas (SwitchLess) and the unlimited Unlim Day Pass by the day. Airalo = a very broad catalogue (several hundred plans per destination), the long-standing market benchmark, with both fixed and unlimited plans. Airalo is also available on Datadopt: see our dedicated comparison.
Is my phone compatible with Yesim?▾
iPhone XS and later (2018+), Samsung Galaxy S20 and later, Google Pixel 3+, Xiaomi 13+, global versions of OnePlus 11+ and most recent eSIM smartphones. Check for the "EID" field in Settings → General → About (iPhone) or in the SIM settings (Android). See our complete eSIM smartphone compatibility guide for the detailed list of models.
How fast is Yesim data?▾
It depends on the local partner: 5G in Japan, the United States, Spain and the UAE on compatible partners; 4G+ across most of Europe and Asia; 4G in Morocco, Turkey and Latin America; 3G possible on some exotic destinations. SwitchLess helps you stay on the best available antenna.
