Get a year of bonus data on most Belong mobile plans

Alex Choros - Managing Editor + Group Telco Editor

Last updated 10 February 2026

Telstra's budget brand Belong is running a bonus data deal on most of its mobile plans, offering new customers as much as 120GB of bonus data per month for a whole year.

Data is doubled on most of Belong's plans: customers who pick the 25GB plan will get 50GB, customers who opt for the 40GB will get 80GB, and customerswho go for the 100GB plan will get 200GB. The one exception is the 160GB plan, where customers only get a bonus 80GB on top of the base allowance.

Here are Belong's SIM-only mobile plans:

50GB data at download speeds up to 150Mbps
Uses parts of Telstra’s 5G and 4G mobile networks
Deal: Includes 25GB monthly bonus data for first 12 months when you activate your new service by 30.11.26. T&Cs apply.

The bonus data applies each month for a whole year. This means customers on the 25GB plan will get 50GB each month for 12 months. The data allowance will revert to 25GB after the first year is up.

Belong's mobile plans have unlimited data banking, so any unused data - including bonus data - is saved for later. You only start using data from your data bank if you go over your primary allowance. This means you can always stockpile bonus data and then drop down to a cheaper plan at a later date. Downgrading plans doesn't reset your data bank on Belong.

Belong also has a $25 per month plan with 10GB that is only available to customers after they've already signed up. The smaller allowance and lower monthly fee make it a good choice for anyone looking to burn through their banked data.

Belong's bonus data offer runs until March 23.
