What is an eSIM?

An eSIM (embedded SIM) is a programmable chip already inside your device. Instead of inserting a plastic SIM card, you activate your mobile service digitally—usually by scanning a QR code from WTCO. No waiting, no fiddly trays.

Why switch to eSIM?

For everyday users

• Instant activation — get connected in minutes with a QR code.
• Less hassle — no tiny cards to lose or damage.
• Two numbers, one phone — keep work and personal lines on the same device.

For businesses

• Faster onboarding — deploy numbers to new staff without shipping SIMs.
• Remote friendly — activate or swap services from anywhere.
• More control — manage profiles and plan changes quickly through WTCO.

Device compatibility

Most modern smartphones support eSIM, including:

• Apple iPhone: XS, XR and later (all models, including Pro/Pro Max).
• Samsung Galaxy: S20, S21, S22, S23, S24 series; Note 20; Z Flip and Z Fold models.
• Google Pixel: Pixel 4 and later.
• Others: Oppo Find X3 Pro, X5 Pro and newer; Motorola Edge series; some Huawei and Microsoft Surface Duo devices.

Quick check on your phone: Settings → Mobile/Cellular → Add eSIM (wording may vary).

How to set up eSIM with WTCO

1. Confirm compatibility — see the list above or ask our team.
2. Request your eSIM — WTCO sends a secure QR code.
3. Scan the QR code — on your phone: Settings → Mobile/Cellular → Add eSIM.
4. Finish activation — set your default line for calls/data if prompted. You’re done.

Need a traditional SIM instead? We can provide that too.

Travelling overseas with eSIM

• Enable roaming before you leave Australia.
• Add a WTCO International Travel Pack for predictable costs.
• Keep your WTCO number active and (on many phones) add a local data plan while overseas.
• When you’re back, disable the travel pack and carry on as normal.

Tip: Label your plans (e.g., “WTCO AU” and “Travel Data”) to avoid confusion.

Switching plans or devices

• Change plans fast — WTCO can update your eSIM profile without posting a new card.
• Moving to a new phone? We’ll transfer your eSIM securely.
• Dual-SIM flexibility — many devices let you keep eSIM for work and a physical SIM for personal (or vice-versa).
