I do think some people are looking to use their "unlimited" plans as ISP replacements. They are trying to justify their decisions based on that unfortunate word, "unlimited."
I think you are exactly right.
I think that is the real problem. As I said, mobile data is an expensive and scarce resource.
Unlimited was also something the mobile operators never should have said if they didn't mean it. So they are, and I think rightfully, trying to fix it. The real way to fix it is to charge by the amount of data used. That is why unlimited data is going away. The thing that should logically go with that change in pricing is to eliminate tethering charges.
Once you have pay by the gallon data usage, it no longer matters how you use it and tethering charges should go away.
The person using mobile as a replacement ISP won't like this new pay by the gallon pricing. That person is not me. I'm perfectly fine with with limited data plans.
As it is, I pay for 2 GB and typically don't use over 100 MB. Rarely I'll exceed 200 MB, but not very often. So nobody can argue that I'm the one hurting anyone. I'm not even coming close to using the 2 GB I'm paying for.
So when people start to complain about this issue, they apparently do not read their contracts, and they start to justify their actions. It really does not matter if you only use tethering occasionally, or if you only use your unlimited plan (on your phone) occasionally and tethering to make up the difference.
The simple fact is, you agreed to abide by the rules and if you did not read the contract you signed, you should stop complaining. Rather, people should, not you specifically, DannyB. Smiley!
I agreed to a similar adhesion contract many years ago when I signed up for cable Internet service. No routers allowed. And I did read those unconscionable terms.
We all know how that went. Cable and DSL providers said no routers. Everybody used routers. In particular, I wasn't causing any problems with extraordinary bandwidth usage.
Here we are today where everybody uses routers on their Cable/DSL, those routers cost $30 at your local office supply store, and Cable/DSL has given up trying to prevent people from using multiple computers via a router.
I think this tethering charge will end up going the same way.
It might matter to some people, but having to sign an unfair contract is not an argument that I personally find very convincing. I would again point out my water analogy. The water utility could come up with with an agreement with outrageous terms to charge you extra money for cooking and drinking. They could. And you would agree because you need water. So would you abide by the contract not to use water for cooking and drinking?
A logical argument about tethering could convince me. Pointing out the agreement is unconvincing. So far, I haven't heard any real logical argument how I'm hurting anybody.
And as I said, I very much do consider people using mobile as a replacement ISP to be the problem users, and the mobile operators are rightfully trying to correct the problem.
Thank you very much for your polite replies. I appreciate it. We may simply have to disagree about on the issue of fees for tethering on a limited data plan.
Edit: add this: as for being concerned about "getting caught", I used my development tools to create a custom solution that is used by exactly one user on the planet.
