Saw this at Rothwell woolworths yesterday photo
It's uses 5G so for $99 ($199 most other places) then pretty decent.
4gb ram, 128 gb memory - should be running Android 13 (or updatable to it like the y21s).
Locked to telstra so unlock fee applies. I haven't checked if there are any cheap online unlocked.
The above linked photo says clearance so stock levels vary from store to store.
Edit: thanks to the mods for editing.
Cheapest unlock on eBay is about $45 which breaks the deal of you are looking for an unlocked for.
Good for Telstra/Boost
