Neither of those statements is universally true. It is a tendency, but not a universal rule.

Mobile internet is newer, less essential to many people, and I think mostly more costly to operate for the ISP per amount of data transferred, so this is why it tends to be the case. But there are unlimited mobile plans and limited home plans too in the world.

Where are my Rogers home internet customers at? 🇨🇦

My Comcast has a terabyte monthly data cap. They will send you an email if you get close to it, and if memory serves they allow you one time to go over it before they charge you some.

Even with downloading many big games sometimes when I refresh my PC and using streaming video apps all the time, I've never hit it but have come close several times. I also work from home.

I am lucky to have a local ISP that is amazing. I'm hoping that they never change.

It is a proxy for don't use too much on the busy towers. In small towns it doesn't matter, but if you are in a downtown the tower will have many people connecting to it and the radio frequencies are shared. By putting a limit on everyone they force better sharing of that limited bandwidth. The limit is very large - far more that than the large abusers will use alone, but in a dense areas it is less than the common person will use all at once.

Tmoblie has (or had?) a binge on plan - if you used video (which we quickly figured out meant low quality - but probably good enough for a tiny phone screen) or audio you were using a lot of data, but it was consistent all day and so they didn't have to count it - if the tower doesn't have enough bandwidth for everyone on the first day of the month they have to fix that. That is the real worry: the tower running out of bandwidth on the first day of the month.

My previous home line had a hard cap at 1TB per month. That seemed like a lot at the time, but I think as the internet grows and requires more bandwidth these "sky high" caps will feel smaller and smaller.

Limits on home service used to be more common, but some plans still have caps. My home internet has a cap, it is just really, really high and they charge you more for exceeding it instead of cutting off access.

My phone also has a cap, but the cap means the connection is throttled instead of charging more.

I have had a home plan in the past woth no limit, but they didn't offer service to my new house when I moved.

They convinced the FCC, cellular networks are different than wired, and should have different rules.

Neither my phone internet nor my home internet has a GB limit. The phone internet costs 25€ a month, and home internet 30€.

It depends where you live, Here pay $45usd for unlimited 1Gb/500Mbps Fibre and it is truly unlimited (usually 15-20Tb a month) and  $35usd for unlimited 5G tho it's throttled abit after 60Gb.

Home internet usually does, it’s just pretty high.

My cell provider Telia gives me unlimited internet and calls in all nordic countries, pretty sweet deal as I need to use my phone in more than one of them.

They do have unlimited data plans here and it's at same price as your average wifi plan.

Not all of them do, I've seen that in America data limits on home internet is common, and here in Europe unlimited phone data is common.

Home internet had data limits too. In fact, you originally paid by the minute of usage through your telephone line before flat rates became a thing, blocking all calls in the process. Back in the day we'd use various time limited free trials by AOL and other ISPs to browse (Freenet was a very big one here in Germany), which they kinda threw out battling each other for customers. Look up AOL free trial CDs for example.

Mine Internet at 500gb, but it's only an extra $10 for unlimited data. My cell data is unlimited but I know they throttle speed after a certain amount. At least I don't get charged extra.

Home internet did happen to have a limit in most places prior to the pandemic (at least in California). It was one of the big quiet changes that occurred. For example, ATT used to have 150GB limit about 5 years ago but it kept getting bumped up.

Some home Internet plans do. I’ve seen AT&T had in their terms that if you hit 99GB, they would throttle your speeds.

This was years ago, so not sure if that changed or not.

Satellite plans often had limits too because they didn’t want to encourage lots of usage on their satellites. I haven’t checked in a few years, but last I checked, these weren’t throttle limits either, sometimes they had hard limits where you just couldn’t connect anymore once you hit the limit.
