Very happy with the performance and simplicity. Tried the others and best by far.
We have had a few eSIMs for abroad, but onesim is the best thing that could have happened to us. Top service. Incredibly easy installation. For questions, customer service is there immediately over WhatsApp. Very good value for money.
Very good internet connection abroad. Activation was simple and the internet worked reliably. I am very happy and can recommend onesim.

Everything else you might want to know about traveling with onesim.
A SIM that is built into your phone instead of a plastic card. onesim sends you a data profile to install; once it is on your phone, it connects to local networks the same way a regular SIM would — no swapping, nothing to lose.
Most phones from 2019 on support eSIM, and the phone needs to be carrier-unlocked. The quickest way to be sure is to check your model in the compatibility guide before you buy. Check compatibility
Search for your destination and we show the package that covers it — onesim sells regional packages, so Spain is covered by the Europe plan, Thailand by the Asia plan, and so on. If your trip crosses several countries in the same region, one regional package covers all of them. Then pick the data amount and validity that fit your trip.
Installing the eSIM does not start the clock. Your package starts the first time the eSIM connects to a network in a country it covers, even while mobile data is off. Install at home over Wi-Fi and keep the onesim line switched off until you arrive; if your home country is covered too, the package would start the moment the line connects there.
Yes. onesim is data-only, so your regular SIM stays in your phone for calls, texts and your WhatsApp number. Keep in mind your regular carrier may still charge roaming fees for calls, texts or data on that SIM — turning off its data roaming avoids surprises.
No — onesim provides mobile data only. Calls and messages through apps like WhatsApp, FaceTime or Telegram work over that data. Standard phone calls and SMS still go through your regular SIM at your carrier’s rates.
Message the onesim support team from the app or the website, or start with the setup guide in the help center. If a package cannot be used, the refund policy explains what applies. Read the refund policy
