Does BT Mobile support eSIM?

BT Mobile does not offer eSIMs for residential phone plans, only business customers. The good news is that there are multiple eSIM alternatives available for UK-based locals.

Companies like Holafly offer single-destination and regional travel eSIM solutions, along with a monthly eSIM subscription that doubles as home and travel internet.

How to get and install a BT Mobile eSIM for business

Interested in getting a BT Mobile eSIM plan for your business? Head to BT Mobile’s website, choose your business type, and contact BT to learn more about their plans and eligibility requirements.

Once you’ve chosen your desired plan, place your order and ensure you’ve selected the eSIM option at checkout. If you’re still unsure about how to buy a BT Mobile Business eSIM plan, you can contact BT’s support team for help.

Important ⚠️ Ensure you have an eSIM-compatible phone before purchasing an eSIM plan. Most modern smartphones (iPhone, Samsung, Google Pixel) can support eSIM technology, but it’s crucial to ensure this is the case to successfully use your phone in the UK.

How to activate a new BT Mobile eSIM for business

After successfully placing your order, you’ll receive an eSIM pack with a QR code via email. Setting up your eSIM pack depends on what device you have.

Set up eSIM on iPhone: Go to Settings > Mobile Service > Add eSIM > Use QR code. Then scan the QR code from your email and follow the instructions to complete the setup.
Set up eSIM on Samsung: Go to Device Settings > Connections > SIM Card Manager > Add Mobile Plan > Scan Carrier QR code. Scan the eSIM QR code from your email and follow the instructions to complete the setup. A similar process applies to all Android devices, though some steps may differ slightly.
Set up eSIM on Google Pixel: Go to Device Settings > Network & Internet > Mobile Network > Download a SIM instead > choose to add via a QR code. Scan the QR code from your email and follow the instructions to complete the setup.

If the QR code doesn’t work, you may have to set it up manually. You’ll have to go to Settings > Mobile Data > Add Data Plan > Enter Details Manually > Enter pr.go-esim.com in the SM-DP+ address > Enter your activation code (this is printed below the QR code on your eSIM pack). Leave the confirmation code field blank. The eSIM default pin is 1111.

How to switch from physical to eSIM with BT Business

To swap over from a physical SIM card to an eSIM or transfer your current line over to a new eSIM, contact the BT Mobile eSIM support team. There may be a charge to switch from a physical SIM to an eSIM. You’ll also need the serial number on the eSIM pack to transfer your current line to a new eSIM.

BT eSIM alternatives for the UK

While BT Mobile doesn’t offer eSIMs for non-Business customers, the good news is that many companies offer eSIMs in the UK. Here’s a list to explore other options:

If you’re travelling abroad for a holiday, visit our eSIM store to choose an eSIM for your destination and enjoy high-speed data and peace of mind. Or, as a visitor to the UK, you can opt for an unlimited data eSIM for the UK and choose your own plan duration (between one and 90 days).
