No. I played around on AT&T website to compare the 5g plans. My current 4g unlimited family plan only has 22g of high speed/4g data, but it includes AT&T Watch TV and HBO MAX. The new 5g plan is slightly cheaper (around 10-20/month), includes 100g of high speed data before they limit your speed, but I’ll lose the AT&T Watch TV which means I’ll have to pay more in total for cell + TV.
After reading about how 5g speed in some situations can be slower vs 4g at least for now, I’m in no hurry to change my plan yet. It kinda sucks though to have to change plans/lose features if I want to use the 5g speed on the 12 Pro Max coming this Friday...
