I'm on the 45$ plan(ithink) which includes 500mb of data, and extra data is $5/100mb. However, when I check my usage it says I have used up 110 mb of extra data, and I just recieved a text saying I've used over "$10" worth of data? How could this be if it's only 5$ for every 100 mb?
Because as soon as you go over the 100mb you automatically jump up to the next bracket and then as soon as you pass 200mb you go to the next bracket. Data is in full increments of what's specified for your overage rate.
So whether you use 101mb or 199mb it will cost you $10
