Tesco Mobile eSIM Setup

What is an eSIM and how does it work on Tesco Mobile?

An eSIM (embedded SIM) is a digital SIM card built directly into your phone. Instead of a physical plastic SIM, your Tesco Mobile eSIM is downloaded as a profile over Wi-Fi or mobile data. Once active, it works exactly like a physical SIM — you can make calls, send texts and use mobile data on the Tesco Mobile network.

eSIMs are supported on iPhone XS and later, Google Pixel 3 and later, Samsung Galaxy S20 and later, and most recent Android flagships. You can hold both a physical SIM and an eSIM at the same time on dual SIM devices.

How to set up your Tesco Mobile eSIM

Before starting, make sure you have a stable Wi-Fi connection. You will also need your Tesco Mobile eSIM QR code, which is usually sent by email or displayed in the Tesco Mobile app or account portal after ordering an eSIM.

On iPhone: Go to Settings → Mobile Data → Add eSIM. Choose Use QR Code and scan the QR code provided by Tesco Mobile. Follow the on-screen prompts to label the line and set it as your primary or secondary SIM.

On Android / Samsung: Go to Settings → Connections → SIM Card Manager → Add Mobile Plan. Scan the Tesco Mobile eSIM QR code when prompted. On Google Pixel, go to Settings → Network & Internet → SIMs → Add eSIM.

Activating your Tesco Mobile eSIM

After scanning the QR code, your phone will download the Tesco Mobile eSIM profile. Activation usually takes one to five minutes. Keep Wi-Fi on throughout this process. Once activated, you should see the Tesco Mobile network name in your status bar.

If activation fails, check that your device is eSIM compatible, your Tesco Mobile account has eSIM enabled, and the QR code has not already been used. Each Tesco Mobile eSIM QR code can only be scanned once. Contact Tesco Mobile for a replacement if needed.

Troubleshooting Tesco Mobile eSIM problems

eSIM not activating: Ensure you are connected to Wi-Fi and try restarting your phone, then retry activation from Settings → Mobile Data.

No signal after eSIM activation: Toggle aeroplane mode on and off. If the problem persists, go to Settings → Mobile Data, select your Tesco Mobile eSIM line and check that it is set as the active data SIM.

eSIM profile missing after phone reset: Factory resets erase eSIM profiles on some devices. Contact Tesco Mobile to re-provision your eSIM — you will need your account details.

Cannot transfer eSIM to a new phone: Tesco Mobile eSIM transfers require contacting customer support or using the Tesco Mobile app. You cannot simply scan the same QR code again on a new device.

Follow these steps in order — most issues are resolved by step 1 or 2

eSIM vs physical SIM on Tesco Mobile

Both eSIM and physical SIM give you full access to the Tesco Mobile network with the same speeds and coverage. The main advantages of eSIM are: no need to handle a tiny physical card, instant activation, and the ability to switch between networks without changing SIMs. The main advantage of a physical SIM is compatibility with older devices that do not support eSIM.
