Thank you, UNISIM:)

I've been looking for a service for a long time where to buy such an eSIM using a Russian card. And I can say with confidence, this is the best service! Excellent quality of the Internet, even though it has the cheapest tariffs I've found. Very convenient website. Fast support, when there was a question, they immediately helped. I recommend!

Very good coverage and cheaper than my native providers roaming service. 8 days in Turkey cost me about 6 usd for instagram, gps apps, bank apps and messengers voice and video calls while my friend spent 30-40 usd using our Russian providers sim.

Service is perfect for a busy business traveler. The eSIM setup is quick, and the connection is dependable, even in less-developed regions. It’s convenient, cost- effective, and much better than dealing with local sim cards. It’s a great solution making my trips more productive and less stressful.

I travelled to Thailand with my friends. I offered my friends to buy UNISIM, but they decided to go with local SIMs. We were on a tour to remote islands, I had perfect connection while their SIMs didn't work:) You can trust this eSIM during your travels

Great experience!

Easy to use service! Experienced it while traveling across UAE, Belgium and US. Have never faced any technical issues, always had a stable connection. Also was very useful when I traveled frequently from one country to another as I just had one balance for all of them which I easily could manage.

The best E-Sim i've ever had.

Using this E-SIM you do not need to select a country and internet packages this is what makes this E-SIM unique and attractive and allows you to travel without any worries about the Internet. Price is the lowest at the market and the Internet speed does not suffer at all, you can also share the Internet with friends, which is also quite convenient.
Highly recommend this E-Sim

My trip to Italy was a breeze thanks to UNISIM e-sim. I got it working in just a few minutes, and just like that, I was connected. It's a big deal when you're about to hop on a train and you need internet!

I really liked how easy and affordable it was. I'd recommend UNISIM e-sim to anyone traveling in Europe. It's super handy and won't break the bank.

Just a little shoutout to the UNISIM team: if you could make it cheaper in the Middle East, like in Saudi where I work, that'd be awesome.

Very easy-to-use and reliable eSIM

Very easy-to-use and reliable eSIM. Used it during my last trip to Dubai. Had a stopover in Kuwait for 3 hours and I really enjoyed that I had mobile data there as well with one eSIM. Highly recommend

Convenient Internet access around the world

Very convenient and affordable service for accessing internet wherever you need it. Tried it in four countries and never had any problems with unisim - connection is very fast, easy to top up your account and intuitive website with possibility to install esim in one click. Highly recommend this service both to those who go on a one-time trip, and to those who are constantly on the move!
