The USA eSIM worked out of the box
The USA eSIM worked immediately after activation upon arrival in the USA. The eSIM automatically linked to T-Mobile 5G data and was fast and reliable. On the odd occasion the signal would drop to LTE.

Easy set up before arrival into country
Easy set up before arrival into country. Sim was fully functional upon arrival. I was able to communicate with my family once I switched on my device. Thankful.

So freaking good!
This is so good, I'd never go with any other brand. For this particular trip i was going to Mexico as well as US and boom day off, get a notif, got to US worked straight away. Walked over to Mexico, had to restart but boom data straight away. Honestly never go back to trying to find local sims ever again. This is the best. You could probs just go with data but the calling and unlimited just gave me peace of mind
