I'm currently on Magenta and am seriously contemplating of upgrading to Magenta Max. Before I upgrade, I’m hoping to get some clarification on some of the features from people who have used this plan abroad.

The plan details describe having 5GB of data to use in 215 destinations. It also says I can get 5GB of data for use in Canada and Mexico. Is this separate or also part of the 5GB in the 215 destinations?

How much is it to add an iPad line? Will the tablet line draw from the 5GB pool for my phone or have it's own 5GB abroad? I'm assuming that unlike AT&T, I won't have to pay on a per day basis to roam and that after I exceed the 5GB, I can roam for free at 256Kbps?

When texting or calling Canadian, US, or Mexican numbers from outside North America, I'm assuming it's not free? How much will that cost?

I'm assuming the Apple TV+ benefit is ongoing like Netflix?

I know it comes with Netflix SD. What if I want to upgrade to Netflix 4K? Do I just pay the price difference?
