Reviews
The follow up e-mails and the instructions were superb, and easy to follow. The e-sim worked seamlessly for all the countries I visited.... UK, France and Italy.
Few issues getting started but the very responsive support team helped to resolve them very quickly. Once overseas we always had very reception and availability
2 eSIMs purchased
Awesome service and worked very well when we got to France (Paris) and now Italy from the Top end to south (Milan to now Sicily)
We always cover by travel kon internet through Eastern Europe, Amsterdam, Germany, Italy.
We are very happy and we recommend to other travellers, also value of price 👍
Very good, I have had reception everywhere so far
