The problem switching from cable internet to mobile internet is the amount of data you use.
I have the mid-level cable Internet. I get 350gb of data. My brother lives in the country, so mobile is all he can get and they give him about 10gb of data.
If you use Netflix or similar to stream videos — movies, sports, etc. — they will each up your data amount.
I checked my usage a couple of months ago. Six months earlier, I was using only about 90gb per month. Suddenly, I noticed my previous month had actually used up the entire 350gb. The next month was almost at the limit. I began checking everything I had connected. The main culprit seemed to be a FoxSports app which apparently streamed games in SuperHD. I changed to a different viewing method and my data usage dropped by nearly two-thirds.
DSL is an option locally, but the phone company requires landline phone service, too. I went to Tracfone years ago because the landline phone service was nearing $30/month just for local calls and I make very few phone calls.
Have to have a landline for many reasons, including for my own business so got Vonage. Pay $12 a month which includes unlimited long distance calls - we make a lot of these. Of course, when the internet is down (which is rare but it does happen) we don’t have access but we can use our cell phones to access messages and when the internet is back up we get all of them via email. Combination works for us.
One of the things that we can do which has proved invaluable lately is that we can block up to 100 different numbers. Had a lot of spam calls lately so that helps a bunch.
