Forward thinking telecoms providers, will drop your data back to 64kpbs speeds after the 2GB contracted cap.
You will ALWAYS be online, but you can still choose your own GB data bundle without the risk of data overcharge (obviously, going abroad will need a closer look at the smaller letters in the contract).
The settings are usually done through an fleet admin account provided the telecoms provider (you login a control panel environment at the provider).
Those paid categories are a known set of numbers, usually starting with a specific number for instance 2xxx are for these, 3xxx are for those (country specific though)
>If if there's a cap, it should be working at a lower speed after the cap amount. That way you will NEVER get data overcharges.
Excuse my ignorance but say for example they have a 2 GB cap, what does working at lower speeds mean after say you surpass a 2 GB cap, and how does that prevent overcharges?
Also re the settings, what do you do to enforce those settings you mention across all phones, is this the utilisation of MDM software?
