⭐⭐⭐⭐⭐ After another eSIM failed to work, I bought this one on June 23rd, and it worked perfectly. Installation was easy, and it connected within minutes. During my trip to San Diego, the connection was fast and stable. Google Maps, messaging, and browsing all worked smoothly without any issues. Reliable internet is essential when traveling, and this eSIM gave me peace of mind. I will definitely use it again for my next trip to the USA. Because my previous eSIM was completely unusable, I bought this one on June 23rd, and I'm extremely satisfied. Installation was simple, and it connected within minutes. Throughout my trip to San Diego, the internet was fast and stable; Google Maps, messaging, and browsing were all very smooth.

I used it in LA. I was able to connect from the moment I arrived on the plane, and I never had any trouble connecting anywhere in LA. I could have used SoftBank's "America Hodai" plan, but I didn't want to use it because in the past, I was charged a certain amount for unlimited data usage the moment I picked up a signal. For 4 nights and 6 days, this is definitely better if it costs around 300 yen.

Reviews: AT&T USA 5G eSIM | Daily 100GB | Calls+SMS | Charged by calendar days | QR Code
_TIHK******bmp3jh2026-06-06
This US eSIM is absolutely amazing, and I couldn’t wait to share it with my travel companions. I installed it on my phone right before departure. After landing, I connected to AT&T’s cellular network instantly and got online straight away. The internet speed is fantastic with zero issues. Setup is super straightforward and hassle-free. We visited Las Vegas, and I had reliable service both indoors at hotels and outdoors. Best of all, it supports regular calls, making it really easy to get in touch with Uber and Lyft drivers! My travel buddies relied entirely on me for navigation and contacting ride drivers as soon as we got off the plane. They’ve all ended up purchasing this eSIM for themselves! Do yourselves a favor and grab one—it’s genuinely incredible and priced really well!!

Reviews: USA/Canada/Mexico 5G eSIM | Supports Google Maps / TikTok / ChatGPT | Daily/Total Data Plans | Calendar Day Billing | 1–90 Days | QR Code

It's very convenient when you're abroad, always staying in touch. All messengers, websites, and email work. However, if you're from Russia, our cellular network doesn't work in Canada, meaning calls and text messages don't work, but thanks to this eSIM, you can still get internet.

I used it in Dallas, USA. The signal strength and speed were both fine, and I was able to use Gemini, ChatGPT, Instagram, Google Maps, and TikTok. It connected instantly even in a crowded stadium.
