Maybe temporary suspension of line for 1 to 2 days, to serve as an unwritten warning to the subscriber about the "illegal" use of the 4G phone plan with 4G modem-routers or the PdaNet+ app. If subscriber still continues with the "illegal" use after the line has been reconnected, the account may then be permanently  terminated by U Mobile and the subscriber blacklisted from subscribing to U Mobile.

For postpaid accounts, U Mobile may issue an "exorbitant" last month bill to the "illegal" user for non-approved use of "excessive" Internet data for the previous months, eg 1GB = RM1. If the subscriber does not pay the bill, celco-wide blacklist and/or CTOS action may follow.

Doesn't Chrome Android display a lot of annoying ads that cannot be blocked.? Why not use the Kiwi and Yandex "Chromium" browser that allows extensions like adblockers.? Even the Brave and Samsung Internet browsers have built-in adblockers.

I use Firefox Android 68.0 = can block ads and coin-miners with the Adblock Plus extension/addon and can use the about:config page.
....... Of course, I need to practice safe-browsing since FF 68 is not-up-to-date. The risk of malware infection on my mobile device is low because I am not a high-value target like top professionals, billionaires, companies, celebrities, CEO, etc.

The latest FF Android (85.0.?) has (only.?) the UBlock Origin extension to block ads.

how about the speed ?
