Valutato Great 4.2 / 5 · recensioni verificate
L'eSIM è stata facile da installare. Ha fornito molti dati a un prezzo ragionevole. Da Keflavik a Hofn praticamente non ho mai perso il segnale.
Facile da usare e ottima copertura in Canada e negli Stati Uniti per il prezzo pagato.
La qualità di internet della eSIM è stata impressionante, proprio come mi aspettavo, e il processo di configurazione è stato estremamente semplice.

Breeze keeps you connected across Japan's busiest cities and most rewarding detours. Here's what that looks like on the ground:
Tokyo's transport system is incredibly efficient but can be overwhelming for first-time visitors. BreezeSim data keeps your Suica card topped up, lets you book Shinkansen tickets, and powers essential apps like Navitime and Google Maps, which provide real-time Tokyo Metro and JR East train information. Whether you're navigating Shibuya Crossing or finding your platform in Shinjuku Station, staying connected saves time.
Kyoto's famous temples, shrines, and historic districts are best explored with a reliable data connection. Use your phone to reserve timed-entry tickets where required, navigate the city's bus network, plan an early morning visit to Fushimi Inari, and discover hidden machiya teahouses tucked away in Gion's traditional streets.
From sampling street food in Dotonbori to spending a day at Universal Studios Japan, BreezeSIM data can help you make the most of Osaka. You can check Tabelog restaurant reviews, book last-minute Universal Studios Express Passes, navigate the city's subway system, and avoid missing out on popular attractions.
A connected phone enhances visits to Hiroshima's Peace Memorial Park with streaming audio guides and historical resources. BreezeSIM data also makes it easy to book the JR Ferry to Miyajima, check departure times, and navigate to the famous floating torii gate at Itsukushima Shrine.
eSIM stands for "embedded SIM", because everything you need is digitally built into your smartphone or tablet. Think of it as the evolution of the SIM card, it's just like your old SIM, but better! Now there are no tiny holes or bits of plastic to deal with, so you never have to think about swapping out SIM cards again. Wave goodbye to the old and say hello to the future of mobile connectivity!
You can't make regular network calls or send SMS with your eSIM, but you can keep your existing SIM active if you still want access to these services. Just make sure you confirm any charges with your network provider before you travel. And remember, while Breeze eSIM plans are designed just for data, you can still use messaging and voice apps like WhatsApp, Messenger, iMessage, and more. These apps all work great with the data connection your breeze eSIM provides.
Your eSIM is delivered instantly to your email after purchase, no waiting, no shipping. Setting up your eSIM is easy, and we'll send a step-by-step guide after purchase. Or, you can head to our eSIM installation guide here.
First, you need to make sure you've got a reliable internet connection, so make sure you're connected to Wi-Fi. Go to Settings > Mobile Data > Add Data Plan. This can vary by model, so if you can't see this option, find your steps here.
We'll send you regular updates, and you can check the data used on your eSIM in the My Account area of your Breeze login.

Japan eSIM connects to KDDI (au), one of Japan's three national 5G operators alongside NTT Docomo and SoftBank. Your device automatically connects to the strongest available signal.
