I needed help setting up my eSIM card
I needed help setting up my eSIM card, the support person was patient and walked me thru the process. I highly recommend this company.
Best customer support experience!
Best customer support experience I’ve ever had!
Andoi (the agent) was available immediately for support over chat, helped figuring out the issue I was having and then helped me fix it, all while being friendly and supportive 👍
All in all 5/5 experience 👌
FABULOUS eSIM support
Andoi was literally FABULOUS. I had loads of questions and he was extremely patient, knowledgeable and courteous with good sense of humour.
Gave me great understanding through screenshots. Phenomenal experience to summarize. Well done!!!
Amazing support
Nems supported me with my queries in very agile and friendly way. Strongly recommend
Very professional and fast help
Purchase at your own risk
I bought an eSIM for 7 days - 1 GB package and bought the unlimited WhatsApp and unlimited Google maps add on. However, it wasn’t unlimited as stated and put me in a very difficult position while I was travelling. Upon contacting customer care, they informed me that my unlimited WhatsApp and maps is only valid as long as I have data left- which makes no sense as I wouldn’t purchase the unlimited bundle if I had data and that it was written in fine print somewhere.
Further, upon arriving at Thailand I realized that there are plenty of companies that provide a tourist sim for much cheaper and give 15GB data for the same amount of time for a lesser price. My suggestion to anyone trying to get a good data plan for your travel or tour would be to check out local sims rather than falling for such corporate schemes and wasting money.

Andoi came through when I thought all hope was lost. Thank you!
Hoping for the best!
Just went through the purchase and set up with Andoi, via WhatsApp. Being a person of a "particular age" - I'm often dumbfounded by tech in most forms! My much younger family members and friends recommended eSIM for an upcoming trip (2 days from now) to Italy, Germany and Malta. Andoi was super patient with me (poor agent!) and walked me through everything. The reviews read well here, and I hope I can report the same. If e-SIM customer service is an indication of the actual service - I should be ok :-) Fingers crossed!

Only way to travel with your cell!
Excellent. Saved us from excessive expense from our home provider in Canada and gave us perfect connections throughout Spain and Portugal. Used their tech help to walk me through installation. He was very patient and helpful. Highly recommend this service.
Don’t travel In Italy without eSIM connectivity
I have been using eSIM in Italy and I must say it’s the best connection for your cell phone. The addition of WhatsApp and Google maps is superb. I highly recommend anyone traveling in Europe to use the eSIM method.
