We consider 30GB of data plenty of everyday users, but we double that minimum allowance for those with heavy data needs. Big-mobile plans are best for people who use mobile data every day, particularly when it comes to streaming video. All of our big-data contenders are SIM-only plans with at least 60GB of data.
This month, the Moose Mobile 28.80 SIM Only plan takes out the top spot again. If you’re new to Moose, you lock in great $28.80 monthly pricing for the first 12 months. The SIM-only plan reverts to a $36.80 monthly fee if you stick around after the first year. The Moose Mobile plan comes with 100GB of data with capped 100Mbps speeds on the Optus 4G and 5G networks. There’s also 200GB of data rollover, to store spare gigabytes between months. Alternatively, consider the Spintel $35 Mobile Plan or the Southern Phone Large SIM Only Plan for cheaper regular pricing.
