Australia ALDI Mobile eSIM Guide: Wi-Fi Calling & Low-Cost Keep-Alive (2026)
Complete guide to Australia ALDI Mobile eSIM on Telstra: native +61 physical numbers, 365-day keep-alive from AUD $15, global Wi-Fi Calling, and international SMS receipt.
⚡ Quick Answer (TL;DR Summary)
ALDI Mobile operates on the nationwide Telstra Wholesale network, offering native Australian +61 mobile lines. A single AUD $15 Pay As You Go top-up keeps the line active for 365 days with free worldwide 2FA SMS receipt and Wi-Fi Calling support.
Telstra Wholesale Network & Native +61 Tier-1 Number Trust
ALDI Mobile is a prominent Australian mobile virtual network operator (MVNO) powered by the Telstra Wholesale 4G/5G network, reaching over 98.8% of the Australian population. The assigned +61 physical mobile numbers are first-tier Australian mobile allocations rather than virtual VoIP lines. This ensures flawless compatibility with Australian Big Four banking institutions (CommBank, ANZ, NAB, Westpac), government services (myGov, ATO), and high-security international financial authentication.
365-Day Long-Term Line Preservation & Top-up Economics
- Pay As You Go (PAYG) 365-Day Plan: An entry-level AUD $15 top-up extends the account balance and phone line validity for a full 365 days from the transaction date.
- Free Incoming SMS Globally: Receiving incoming verification codes (2FA) is completely free anywhere in the world whether connected via standard roaming or Wi-Fi Calling, without deducting your PAYG balance.
- Balance Rollover Protection: Recharging before the 365-day expiry date automatically carries over all unused credit into the new 365-day cycle indefinitely.
- Compared to postpaid plans from Optus or Vodafone, ALDI Mobile reduces the annual cost of holding an authentic Australian number to roughly one-quarter.
Global Wi-Fi Calling (WFC) Experience & Setup
- Official Wi-Fi Calling Support: ALDI Mobile provides native Wi-Fi Calling. When connected to reliable Wi-Fi or using cellular backup calling on a secondary SIM overseas, the status bar displays "ALDI Mobile Wi-Fi".
- Domestic Rate Billing: Calls placed and received over Wi-Fi Calling are billed at standard domestic Australian rates, avoiding expensive international roaming tariffs.
- Broad Device Compatibility: Works seamlessly on iPhone 6s and newer, Google Pixel, Samsung Galaxy, and other carrier-certified VoLTE smartphones.
Online Application, ID Verification (KYC), and eSIM Activation
- Visit the official website (aldimobile.com.au), select an eSIM Starter Pack, and provide a valid email and Australian postal address.
- Complete mandatory Australian identity verification (KYC) online using an international passport and valid visa (e.g. tourist, student, or graduate visa) via the automated Document Verification Service (DVS).
- Receive the confirmation email containing the eSIM QR code PDF within minutes of automated approval.
- Navigate to "Settings -> Cellular -> Add eSIM" on your handset, scan the QR code, enable "Wi-Fi Calling", and keep "Data Roaming" disabled on this profile to prevent unexpected data charges.
Troubleshooting & Best Practices
- APN Configuration: Ensure the Cellular Data APN is set to "mdata.net.au" if mobile data or MMS does not connect automatically.
- Calendar Reminders: Set a reminder for day 350 to top up before the 365-day validity expires, as exceeding the 90-day grace period results in permanent number cancellation.
- eSIM Profile Replacement: The provided QR code is single-use. When changing handsets, log into your ALDI Mobile dashboard to request a free replacement eSIM QR code.
