I've repurchased this multiple times. It's ready to use immediately upon arrival, and renewals are very convenient. Checking usage on the website is easy, and data sharing is supported. Internet connectivity is consistently smooth across different locations in Spain.

Great option from Trip with this esim. Easy to install and works immediately. Data only and no sms or call. So I can still use my local country number and messages should someone wants to call me.

Reviews: Europe Orange eSIM | Total 20GB–100GB | Unlimited calls & SMS in Europe | 7–30 days | QR code
Guest User2026-02-24
During this trip, I used the service in Barcelona and Seville, Spain; Faro (southern Portugal); and Lisbon, Portugal. The phone was installed on my iPhone 13 Pro Max, and connections were stable throughout. Note that these areas are not Orange's primary service areas, so roaming for the SIM card needed to be enabled, which slightly increased battery consumption. I also used my phone's hotspot for connecting my laptop, and the connection remained stable. I highly recommend this e-SIM service; the price is reasonable, and the service quality is consistent.

It works great! We bought 20GB for a month, but it only lasted two weeks (we shared the data with a second device). Extensions are possible. We decided to try an eSIM only for Asia, as it seemed a bit cheaper. In any case, the internet quality is excellent; we had 5G almost everywhere. Connecting is also easy with a QR code.

It's easy to use, just install it. I used maps and sent pictures and it went into low speed mode within half a day. The signal was good and I was able to use it without any problems.
