Great experience. My internet was faster than other people who were using their $5 roaming on Australian SIM cards.

I'm very happy with the purchase; everything is convenient and easy. They're always available, and they have city maps. This was my first time using this, but I'll be using it all the time now. Thank you for this opportunity.

I used it in the Netherlands, Belgium, and Switzerland. It worked perfectly and smoothly without any problems! The large data capacity was great; I could use Google Maps and other apps without worrying about data limits. Thank you!

Reviews: UK 5G eSIM | CTExcel (EE Network) | Total Data with Calls & SMS | 7-30 Days | 24-Hour Billing | QR Code
Guest User2026-04-10
This SIM card allows you to make calls to UK numbers, and the signal is excellent. However, once you get into populated areas, the signal weakens to LTE on all devices, especially those with roaming enabled. The convenience of being able to use UK numbers eliminates signal and internet congestion issues. I highly recommend it, especially for travelers who have friends or relatives using UK numbers or who use phone calls for bookings. Importantly, unlimited calls are included. I'll definitely use it again on my next trip.
