eSIM was easy to installed. I tap on the phone from the order and done in about 3 minutes, activate data roaming and off you go, can access everything from WhatsApp to YouTube. Google in China. Speed outs good and upload is fast. Chew through data a bit.★

I relied on this site for my plane tickets and eSIM for this trip as well! I always use this site because I'm always worried about unexpected problems during overseas travel, and they provide excellent support. This time, I had trouble registering my eSIM, which caused a lot of trouble at the transit airport, but thanks to communication via LINE, I was finally able to use it, and I had a wonderful time during my stay in the US! Thank you to the staff member who patiently helped me via LINE. I hope that next time, I'll be able to use my eSIM without any problems!★

Reviews: United States 5G eSIM | Full coverage by three networks | Supports ChatGPT | Daily plan/total data | 24-hour billing | QR code
Guest User2026-11-14
This experience using eSIM was excellent. Installation and setup were simple and convenient, without needing to replace the physical SIM card. Upon arrival, I was able to quickly connect to the internet. The network speed was stable and smooth, making it easy to check maps, search for information, and conduct daily communications. The price was also reasonable. I will definitely repurchase it next time I travel abroad. I recommend it to anyone who needs internet access while traveling overseas!★

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!!★
