An esim pack is a QR code that you sim swap to in order to use o2 services instead of a physical sim card..
You can order one from customer services If you message O2 on Facebook (https://o2uk.co/O2CFB) , Twitter (https://o2uk.co/O2CTW) or Instagram (https://o2uk.co/O2CIG) , they should be able to help you with this
- Xperia 1V - o2 and Spusu
- Pixel 8 Pro - o2 and Vodafone UK
