So easy, fast, reliable.
So easy. Three phones in our travel group needed an eSIM for USA. Purchase and delivery was fast and simple. Installing the eSIM at the airport was easy and the guide given was spot on.
Unlimited high speed data always connected and reliable was perfect.

Holafly stopped working before term was up
I set up Holafly for 35 days from 31 March for a trip to USA. It worked perfectly for 30 days then didn't work any more. I requested assistance through their website and communicated with a bot .. eventually asked to engage with a human being who was no better than the bot. Long story short started a new contract with MicroeSIM which is working perfectly

I felt safe every where I traveled from Switzerland to Paris knowing I had HolaFly! I used my phones for Google Maps, train and hotel apps, texting and calling my family back in the USA and never had any problem whatsoever.

SIMple set up, good value peace-of-mind
Used Holafly in India, and now the USA. Easy to navigate pricing, easy to purchase, and easy(ish) to install. Many others out there, but Holafly made getting peace-of-mind, whilst roaming, easy.

Made travelling easier
I’ve not used an eSIM abroad before & felt Holafly would best fit my needs in the USA. What a huge difference it made to my stay there! Unlimited data meant we could use Google Maps & never get lost, which was a relief especially. The price we paid for our stay was well worth it & I would most definitely use Holafly again.

I travelled in the USA for three weeks…
I travelled in the USA for three weeks and used an ESIM with unlimited data. It was reliable and quick, and my family could use my personal hotspot. We had data the whole trip with no issues. It was so easy to choose the right plan and get the eSIM working.
