Not counting my cellular line, I have two sources of Internet. The first is my home internet which is used most often. The second is internet service on my tablet which is used when I take my tablet out.
Comcast Internet Essentials program provides me for a 50/10MBPS internet connection. One disadvantage of this service is I must use their inferior router/modem which has to be rebooted every week or two. When I am home, all of my devices connects to the home internet service which makes life a lot easier. I am also capped at 1.2TB of data, but yet to have received a warning about getting close to my cap. I budget $10/month and pay monthly.
My second internet service is with T-Mobile providing data service with my iPad mini. With T-Mobile, I receive either 4G, or 5G service which doesn’t matter which one. And while my account number is formatted as a telephone number, I do not have a telephone number attached to my tablet. This is a shame because iPads have the Messages app which could have been used with a telephone number. For T-Mobile, I budget $15/month and pay monthly.
