Hello how may I help you? I have a question about my account Sure, what is it? How much data do I have per month? You get 20 Gb per month Okay. How many GB have I used up so far You've used 19 GB so far this month. Wow, that's more than I expected If you'd like, you can double your amount of data for only 10 dollars more. Yeah, let's do that. Don't want to run out Great! Now you have 40 GB of data. Thanks
