Airsim 10/10

I'm, in the US right now and have not had an issue at all since landing from Australia. Very happy with the esim I purchased 20gb Northern America (Canada and Mexico) 3 months. This is the second time using airsim and I highly recommend them, I will definitely use them again in the future

Excellent choice

I bought an esim not knowing exactly what I was doing as I never had one before and im nearly 60yrs old. Looked around for the best deal and what I required and airsim came up with 10gb for 30days. I was only going to Morocco for 1 week and I planned on only using data when I was out at night or if hotel wifi was rubbish.
It was very easy to set up, I didnt use all the data, but it worked a treat on fb wa tiktok and everything else, If needed to speak to the kids and grandkids.
I would recommend them to anyone of my friends and family. I bought a 10pound sim at the airport that was suppose to last a week of unlimited but it stopped working after 3 days. Glad I got the esim for myself before I left the uk. 😆

Good for a pilot backup eSIM

I used airsims bigger GB plans in the past for individual countries - pretty good and cheap. As a pilot for a SE Asian carrier, I use this mainly as a backup on my personal iPhone when my company phone has roaming or web filtering issues. No app needed (not a fan of eSIM apps) and is easy to use. 120 country is not the cheapest global eSIM, but reliable and 365 days makes it a good deal in the end. No problems. Good option for frequent travelers who need dependable data for many countries but use WiFi or company phone mostly. Long expiry is very good. Would be nice if the price was bit lower for highrr GB, but it’s ok I’m not heavy user when I’m working.. thanks.

We mainly spent time on the Big Island of Hawaii

We mainly spent time on the Big Island of Hawaii, a very remote area, also the connection can be slow sometimes, but largely fine. So this Esim is good value and highly recommend
