HUGE mobile plan deal: Worth 6 months free (yes, really)

Key takeaways
- Southern Phone is offering new customers a $75 bill credit across all mobile plans, as long as they stay connected until 1 June 2026.
- On top of this, you can also get a $75 Finder Reward as a Visa gift card when you keep your SIM-only plan active until 15 July 2026.
- Example: If you sign up to Southern Phone's Small plan ($24 a month for 20GB), you're effectively getting 6 months free, thanks to $150 in credits and rewards.
Southern Phone may not be offering a "price discount" on its plans like some other providers, but you still get a bill credit (as shown in the green box in the table) plus a $75 Finder Reward.

Is this Southern Phone deal too good to be true?
It's actually a pretty good offer, so hear us out.
The $75 bill credit offer runs until 31 May, and you just need to stay connected until 1 June to receive it, so there's not a huge gap in between.
Then there's the $75 Finder Reward. One of the main eligibility requirements is staying connected for at least 45 days after the promo ends on 31 May.
That takes you to mid-July, which again isn't a long wait either.

What do I need to know about Southern Phone's mobile plans before signing up?
Southern Phone is known as a budget-friendly mobile provider, and its ongoing prices, even without discounts or credits, are still pretty solid for the amount of data you get.
If you're not someone who switches providers regularly or once a promo period ends, that's good to keep in mind.
Here's a quick rundown of what features you can expect, including the good bits and what to watch out for.
- Access to the Optus 4G and 5G networks.
- While 5G download speeds are capped at 100Mbps, this is plenty for online activities on your phone, like streaming and gaming.
- $50 credit for standard international calls.
- Live chat support is available via its website.
- Option to add on international roaming if you're heading overseas.
- There's a steep $10 per 1GB charge if you go over your monthly data allowance.
