if you want to get this offers just lower your monthly to lowest tier like $40 for whatever data they offer you and wait a month and you will keep getting this promos every month just to upgrade you on higher tier.
I'm stuck at $50 for 10gb and i keep getting offer only above that nothing like $45- $50 for 15-20gb, They will never offer you any extra data on existing plan only higher tier.
