Unlimited data

Unlimited does mean what it says on the tin, however it's also good to know that there is a section on "responsible use" within the T&Cs (which Strandloper mentions) .. I have loosely extracted the bits that might be relevant:

- You must not use SMARTY Services .. for unsolicited bulk or commercial communications (relating to SMS)
- To download, send or upload content of an excessive size, quantity or frequency. We’ll contact you if your use is excessive;
- Our Unlimited Data Only SIM plans are for personal, non-commercial use only and can be used in SIM enabled tablets or laptops and portable mobile WI-FI devices and is uncapped for this use
- This SIM card should not be used as a permanent long-term alternative to home broadband.

+ a few other things, you can read more in the actual document here if interested. Service could be suspended without warning if usage is excessive, or if the terms are not adhered to.
