I had been using the Knowroaming SIM card for travel from 2018 with great satisfaction. That service was coming to an end and I was upgrading my phone. Therefore the option of an eSIM was considered. I reviewed other providers and eventually decided the knowroaming eSIM was my most economic option for the travel plans that I had. Before you can order install and activate that eSIM to have to create an account. In creating the account you have to await the email reply from Knowroaming for you to respond to verify that email for activation before you can login to order that eSIM. Only then can you install and activate that eSIM. Their help sytem make it relatively straightforward to install and activate the eSIM. I recieved an update when about 50% of my data plan was used up and I found that helpful in planning whether to further update the data package for the balance of my trip. Knowroaming was acompany that I knew and their data package rate are very attractive in comparison to others that I considered. I heartily recommend Knowroaming eSIM for use in travel outside your home base.
