Joining boost 35Gb ($15) online-3 month offer and then change To 5gb ($20)?
I've just moved to rural NSW and I don't have much coverage with my Optus provider. I'm considering switching to boost. There is an online offer for new customers: 35GB for $15 during the first three recharges (this plan usually is $30) and finishes today!
In case that I join boost and choose this offer, would I be able to switch to another plan whenever I want to (eg. I may want to switch to the 5GB -$20 plan after the three first initial recharges)?
Using boost as my phone provider, can I recharge each month the amount of $/plan that I need (eg. one month $20-5GB, another month $30-20GB)? I understand that I do recharge every 28 days and I wonder if this is possible?
