Yesim — Full Guide 2026
eSIM & Internet · Our commission: 18% of the plan price.
Yesim is an eSIM service that gives you mobile data abroad — and something extra: a virtual phone number. Like Airalo, Yesim sells digital SIM cards that you install on your phone before you travel, so you have internet the moment you land. But Yesim also offers a virtual number that lets you receive calls and SMS messages, and an international number option for people who need to stay reachable while they travel. Yesim covers more than 170 countries, with local plans, regional plans and a global plan, and its app lets you manage your data, top up, and check your usage in one place.
TL;DR — The Short Version
What it is: an eSIM service with mobile data and a virtual phone number. Best for: travellers who want data and a reachable number in one app. How it works: buy a plan, install the eSIM, activate on arrival. Coverage: 170+ countries, with local, regional and global plans.
What is Yesim?
Yesim works like other eSIM services: you buy a data plan for your destination, install it on your phone from the Yesim app, and turn it on when you arrive. Your home SIM stays in the phone, so you keep your own number for calls and texts.
What makes Yesim different is the virtual number: for an extra cost, you can get a number that receives calls and SMS, which is useful if you are waiting for a bank code, a booking confirmation, or a call from home while you travel.
Yesim also offers a pay-as-you-go option in some countries, so you only pay for the data you use, and a global plan that works across many countries without changing the eSIM. The app shows your data usage in real time, so you always know how much you have left.
What You Can Book With Yesim
Here is what you can book with Yesim:
- Local eSIMs: data plans for one country, from a few days to a month.
- Regional eSIMs: one eSIM covering a whole region, such as Europe or Asia.
- Global eSIM: data that works in many countries around the world on one plan.
- Virtual numbers: a number that receives calls and SMS while you travel, so you stay reachable.
- Pay-as-you-go data: in some countries, pay only for the data you actually use.
How to Book With Yesim — Step by Step
- Check your phone supports eSIM — most modern iPhones and Android phones do.
- Open Yesim through our link and choose your destination and plan — local, regional or global.
- Pay by card and install the eSIM from the Yesim app by following the instructions.
- Turn the eSIM on when you land and switch your mobile data to it.
- Top up in the app if you run low on data, or add a virtual number if you need one.
Who Is Yesim Best For?
Yesim is best for travellers who want data and a reachable phone number in one service — for example, digital nomads, business travellers, and people who receive bank codes or booking confirmations by SMS while they travel.
It is also good for multi-country trips, because the regional and global plans mean you do not need a new eSIM in every country.
If you only need data and nothing else, Airalo or Saily may be slightly cheaper on some routes — but if the virtual number matters to you, Yesim is the one to pick.
Why a Virtual Number Matters When You Travel
Most travel eSIMs give you data only — no phone number. That is fine for maps and messaging, but it becomes a problem when a bank, an airline or a hotel needs to send you an SMS code.
Many banks send a one-time code by SMS when you pay online or log in, and if your home SIM is off or has no roaming, you cannot receive it.
A virtual number from Yesim solves this: you get a number that can receive calls and SMS while you travel, so codes and confirmations reach you. It is also useful if you run a small business or freelance while travelling — clients can reach you on one number wherever you are.
The virtual number is an add-on, so you only pay for it if you need it — but for a long trip or a work trip, it is a small price for peace of mind.
