Pay Monthly mobile plans
If you reach your max speed data allowance, you can keep using endless data at a reduced speed - to carry on doing the things you love.

Here’s how Group plans with Companions work:
Benefits:
- No more sharing. Everyone gets their own endless data plus endless calls and TXTs to standard NZ and AUS numbers.
- Hotspot included at no extra cost.
- Managing costs is easy with one bill.
