I’ve been using this “e-sim on” service for the second time now, in different countries, and I absolutely love it! The service is incredibly reliable and convenient. A special thanks to Kim from client support—always responsive within seconds and super helpful. I truly appreciate how fast and efficient this service is. Highly recommended!
Amazing Help with installation I not Tec savvy and was having an issue installing Carl helped with a step by step guide to get me on my eSIM by the WhatsApp service Perfect 5 stars ❤️
Nems and Carl had been very helpful, responsive and professional when I tried to explore the correct choice of esims for my use.
Perfect eSim operation. Perfect and timeous assistance from the eSim-On agents. Very knowledgeable staff.
Really very helpful and straight to the point especially for old man like me... Thank you Nems
ESIM-On has never failed me. Many provide the eSIM roaming service but only eSIM-On is always there with instantaneous support over WhatsApp or email depending on the urgency. I am a frequent traveler and I have needed the support for various reasons over the last year. At least 3 times in emergency situations. And all the times it was solved immediately within 5 minutes. I appreciate and like that and that’s why I don’t switch even if there’s a small cost difference in packages. One time they had to remotely switch on my eSIM of course with my permission that I had to give consent to. But they still managed to resolve my situation and within minutes I was connected. Not had this service from anyone else and I don’t see how others will match.
Absolutely the most helpful person ever experienced in the other end of the chat helping me out. Nems is an absolute superstar!! Thank your sir!!!
