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 used a US 5G eSIM for 25 days, using 1GB/day. The connection speed was fast, and it worked in most areas except for some parts of national parks. I installed it in Japan and activated it upon arrival in the US. It was easy to use.

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!!

The signal in Peru was very good. But in Punta Cana it wasn't good, although customer service was excellent; they replaced my eSIM right away and were very helpful.
