what are some great verizon MVNOs to try out?

there has been price increases for Verizon and i anticipate helping my relatives change to either get more discounts from Verizon or changing to MVNOs entirely. They use like 2GB data max per month and they call maybe 120 minutes a month and send like 200 texts a month. They mainly use their wifi at home with their iphone se and iphone 10.

What MVNO should I research more and are these MVNOs aggressive with their price hikes? Thanks!
