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
Guest User2026-06-06
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: US T-Mobile 5G eSIM | Local IP | Total Storage 2GB-75GB | 5-30 Days | US Local Calls | Calendar Days | Instant Use | QR Code
Guest User2026-05-15
This T-Mobile eSIM exceeded my expectations. Blazing 5G speeds made video calls and maps navigation smooth throughout my trip. The US local IP let me access all major communication apps without restrictions. Voice minutes worked perfectly for local calls, which was a huge plus. Activation took less than two minutes, and signal was strong even in suburban areas. Will definitely buy again on my next trip to America.

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.
