Reviews: Europe Orange 4G eSIM| Calls + SMS | French phone number | 24-hour billing | QR code
Guest User2026-06-02
The SIM card connected quickly. The signal was strong everywhere. Sometimes the connection became unstable in large buildings and between towns, but I think that's normal. The ability to make calls and send/receive text messages was useful.★

My family in the UK suggested Lyca, as they all use it. It’s a really good product, and I noticed it’s widely available in retail stores.
