Reviews: Multiple European countries CTExcel 5G eSIM | EE Internet United Kingdom number | Supports calls & SMS register app | Local phone customer support | 7-30 days | QR code

I used it in Aarhus, Denmark; Byunilis and Kaunas, Lithuania; and Bologna, Venice, and Milan, Italy. It took about 5 minutes to connect after entering Denmark, but after that, it was reliable and problem-free. My stay was 3 weeks, but when I called the toll-free number to check my remaining data, the call was in Chinese, which I couldn't understand. Accessing the website required logging in, which was frankly confusing. I think it would be even better if there were more explanations regarding these things. That said, overall, I would recommend it.

I used to buy it on websites, but this time I bought it through Trip and it turned out to be very profitable. The internet worked in Turkey, France, and Greece, I’m very happy.

The best coverage. Excellent connection and speed. Easy setup without a bunch of settings. Thank you! We were always connected. Video format doesn't lag either. I tried a continental SIM card, but nothing worked. With a global eSIM, everything is absolutely simple. I highly recommend it to anyone who has an eSIM-compatible phone. The assistant support is also excellent. I love TripCom.

It works great. I got it for 12 days at 3GB per day, and it only cost me $10! ​​I can confirm it works great in the Czech Republic, Germany, and Portugal. I recommend it to everyone!
