Unresponsive but keep your money

Unresponsive! They stole my money. I ordered a e-Sim with an activation date earlier this week and they never did anything. Beware and think twice before buying something from them. They might just decide to ignore your calls, emails, chat messages leaving you totally powerless. Multiple attempts to solve this situation amicably but it is hard to do anything when customer service is ghosting you!

Extremely Disappointed – Paid but Never Received eSIM

I purchased an eSIM for use in the USA three days prior to my departure, expecting a smooth and prompt delivery as advertised. Unfortunately, not only did I never receive the eSIM, but my repeated follow-ups went completely unanswered.

Despite multiple attempts to contact support, I was met with complete silence. Yet, the payment was processed instantly, and they had no issue taking my money.

This experience caused unnecessary stress during my travels, as I had to find alternative options last minute. I expected better communication, especially for a service that travelers rely on while abroad.

I do not recommend this provider based on this experience. I hope they take steps to improve their customer service and delivery reliability in the future. I recommend Holafly.

Warning

The first 2 orders Paypal rejected the order. Direct payment confirmed order but no esim had been delivered. No communication possible. Review stars do not match company.

Delay in delivery.

Need to write in for them to send over after 3 business day as no acknowledgement from them after purchase. Website not stable, prompt to a website which blocked by antivirus program. Sim still deliver in the end, hope it's activated on that day as indicated on their website.

The e-sim is working just fine

The e-sim is working just fine, there are two things that would help the experience.
1. It would be good if it was clear on the website that the charges are in USD. My internet search specified Canada, so I expected to be charged in CAD. That is not the case.
2. It would be good if it was quite clear at the outset that the e-sim would be delivered by email on the day that it is to be activated, rather than at the time of order, with activation on the date of travel.

Check phone compatibility? Better info on website needed, but good if it works

Ordered two sims for my friend at myself upon our visit to the US. The information on the website wasn't super clear, but there was helpful online chat. They arrived very fast, and we picked our activation date to be the day of arrival in the US. For my friend (Redmi phone), she just put the sim in and it worked, received a text with the phone number, all good. For me (Samsung), the data didn't work. I received and texted fine, I had signal, but the data sign was missing. I called for assistance, we added manually a LYCA network, and from that moment I barely had a very low signal here and there. I basically relied on my friend for google maps etc. We stayed within Philadelphia centre and Manhattan NY area, but apart from 5min for 2 times, I never had 4G, not even any lower type of signal.
