Thank you for letting us know and as we carefully check here your plan is getting high discount which gives your almost $68.34 for plan services and device,‬ we do have choice to switch for T-Mobile Essentials Saver plan that cost $100 plan services for the 3 lines. 

But there will be a downside if we switch plan. The promotion for Samsung Galaxy S22 will be removed because the plan is not eligible.

But I do highly suggest to keep your plan because your device is eligible for your current plan.

I'm seeing as well here that you have Protection feature which is optional. You can remove the feature insurance on your lines, however this means that device(s) is no longer covered in case of accidental damage as well as lost/stolen. Once it was removed, you can only add it back in the future if you upgrade. May I know your thoughts on this?
