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.

eSIMs are cheaper than buying physical SIM cards outside, and you get signal right at the airport if you've already set them up at home. This is my first time buying one, but it's great.

Reviews: Europe Orange 4G/5G eSIM | Total 20GB–500GB | French number with calls & SMS | 7–30 days | 24-hour billing | 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.

Reviews: United Kingdom 5G eSIM | Dual Network Coverage | Full AI & TikTok Access | 1-30 Days | Instant QR
Guest User2026-02-26
I only decided to buy an eSIM before my trip to the UK, and the experience exceeded my expectations. It was incredibly convenient – ​​buy and use immediately! I received a QR code right after payment, scanned it, and activated the service without needing to change my physical SIM card. The network speed was stable in London, on the Underground, and even in the suburbs. It's fantastic for someone like me who hates hassle!
