55+ Unlimited is a targeted plan, it isn't something you get automatically just because you're in that market. 55+ Unlimited is also basically cheaper Go Unlimited, if one line had Beyond, you wouldn't have liked the plan in the first place. On VZW's plan page, it also mentions that line access changes based off number of lines. Planes para teléfonos móviles, llamadas y textos ilimitados, servicio prepagado y más
You're so ridiculously impatient lol, I feel sorry for the poor AT&T rep you'll eventually berate because you weren't answered immediately ON A COMMUNITY FORUM WEEKEND instead of reaching out to a live agent on the phone.
