OnesimReviews of onesim.co

Excellent service at a great price. Kept me connected in London and again in Ireland at a fraction of the cost of my US network.

Really great eSIM and great service to make it work when I had troubles to get it to work!

Good network coverage, but inaccurate data counter. Purchased two esims from Onesim of 10GB and they both stopped at 9.3GB. Not good.

The purchase was easy, E-sim worked properly in both my trip destinations. Can't complain. Definitely recommend it!

Easy to setup and worked better than the other sim cared that we tried.

Easy to purchase, good speed in the visited countries (Italy, Spain, Switzerland)

everything went smoothly, had internet in france and italy. full 5G speed. But i went to monaco and there it was not working. With my other carrier i had internet in monaco which should be included in france package. would definitly buy it again!

Absolutely great for travelling
