I used eSIMCircle during my two-week vacation in Thailand, and it was incredibly convenient. From the moment I landed in Bangkok, I had instant 4G access without needing to find a SIM shop or deal with language barriers. The setup took less than five minutes, and the signal was strong not only in Bangkok but also in Chiang Mai. I especially loved being able to use Grab and Google Maps without any delays. eSIMCircle made my trip so much smoothe-definitely using it again for my next adventure!

I’ve used eSIMCircle across the UK, Netherlands, and Belgium, and it performed flawlessly every time. Buying the plan and activating it took no more than a minute. It gave me better internet than my travel companion’s roaming plan. The coverage and speed were far superior, and the process was refreshingly simple. I’ll be recommending this to all my fellow travelers.

Quick, easy, and reliable! I got eSIMCircle set up before my flight and activated it as soon as I landed. I was online in under 3 minutes. Speeds were excellent - up to 100Mbps in some areas. Their step-by-step guide was super helpful. The live chat support also gave me confidence. Great coverage, great support, and very affordable!

As a full-time remote worker, I need uninterrupted internet wherever I go. I used eSIMCircle’s unlimited data plan while living in Vietnam for a month, and it never failed me. I hosted Zoom meetings, uploaded videos, and even streamed Netflix in HD, all without buffering. I even used hotspot on my laptop! For digital nomads, this is an absolute game-changer.

I faced a minor hiccup while installing the eSIM on my Galaxy S22 in Thailand, but eSIMCircle’s support team was incredible. I reached out through live chat at midnight, and someone responded in under 2 minutes. They guided me step-by-step and had me online in no time. The connection was super smooth even in crowded places like Chatuchak and central Bangkok. Amazing service!

I wanted something I could set up in advance and activate only when I was ready - and eSIMCircle made that possible. It took just a few clicks to install, and it activated instantly once I landed. No fiddling with SIM cards or finding a shop overseas. I had internet from the moment I touched down. Absolutely love the convenience.

I had doubts at first, but eSIMCircle exceeded all expectations during my trip to Japan. The activation was easy, the connection was stable, and I paid way less than what my local carrier would’ve charged for international data. Just $35 for 30 days with 20GB of high-speed data! I’ll definitely be using this again for my future trips - reliable, convenient, and budget-friendly.

During my 10-day trip to Indonesia, I relied on eSIMCircle for all my mobile needs. The connection was strong in Jakarta and Bali, and although the signal dropped to 3G when I visited Komodo Island, it was still usable. As long as you're staying in urban areas, you can count on reliable internet with eSIMCircle.

I traveled across 7 European countries in just over two weeks, and eSIMCircle truly made the trip stress-free. From France to Italy to Germany, I had seamless internet access without juggling multiple SIM cards. Fast 5G in major cities meant easy navigation, HD video calls, and real-time uploads. I ended up saving more than $100 on roaming charges. This is hands-down a must-have for anyone traveling to Europe!
