Apple's iPhone 18 Pro, iPhone 18 Pro Max and the brand-new foldable iPhone 18 Ultra land in Australian stores on Friday, 18 September 2026, with pre-orders open from Saturday, 12 September. If you're upgrading, the phone is only half the equation, the right SIM plan matters just as much, especially with faster cameras, bigger displays, and heavier data habits on the way.
Here's how to match a Lyca Mobile plan to how you'll use your new iPhone.
Why Your Data Needs are About to Change
The iPhone 18 Pro and Pro Max bring a new 48MP Fusion main camera with variable aperture, up to a 6.9-inch display on the Pro Max, and for the first time a foldable form factor with a 7.8-inch inner screen on the iPhone 18 Ultra. Bigger screens and better cameras generally mean:
● More 4K/high-res video shot and shared
● Heavier iCloud Photos and video sync
● More streaming on that larger foldable display
● Faster downloads, if your plan can keep up
Lyca Mobile runs on Vodafone's 4G/5G network in Australia, so every plan below gets solid coverage the difference is how much data and flexibility you get for your money.
Match your plan to your iPhone 18
Everyday user - LycaPlan S
50GB - $15/28 days (first 6 renewals). A good fit for anyone using the iPhone 18's improved camera regularly and backing photos up to iCloud over mobile data now and then. Comes with 5G access, unlimited calls and texts, and international minutes.
Power user / new Pro Max or Ultra owner - LycaPlan M
Up to 120GB $20/28 days (first 6 renewals). If you've gone for the Pro Max or the new foldable Ultra, this is the plan built for you. The bigger screens are made for streaming and the improved cameras are made for shooting 120GB gives you room to do both without watching your data bar all month. Also includes unlimited calling to 35 countries, handy if family or friends overseas are asking to see your new phone on a video call.
Set-and-forget Long-Term Plans (Medium & Large)
Medium: 360GB total, 30GB every 30 days $150/12 renewals.
Large: 900GB total, 75GB every 30 days $220/12 renewals. For anyone who'd rather not think about recharging every 28 days, Lyca's long-term plans spread generous data across a full year. If the iPhone 18 Ultra becomes your main camera, laptop-replacement, and entertainment screen, the Large plan's 75GB every 30 days gives real breathing room.
eSIM Makes Switching Easy on Launch Day
Every iPhone 18 model supports eSIM, and so does Lyca Mobile. That means if you're upgrading on release day, you can:
- Order or pick up your new iPhone 18
- Activate a Lyca Mobile eSIM instantly by scanning a QR code — no waiting for a physical SIM to arrive
- Keep your existing number by porting it across during setup
No lock-in contracts, no credit checks — just pick a plan, activate, and you're online before you've finished setting up Face ID.
The bigger and more capable your new iPhone 18 is, the more data headroom it's worth having. Casual users can stay on SM or S; anyone with a Pro Max or the new foldable Ultra will get the most out of LycaPlan M or a long-term plan. Whichever you choose - rollover data up to 500GB means you're never really starting from zero.
