Monthly mobile fees in the USA can be very expensive. Unless you join a family plan you are expected to pay from 40 to 75$ per month.
If you are always connected to wifi at home and at work and you only use data to chat and book Uber then Mint Sim might be the right choice for you.
For 15$ a month you will get unlimited calls and text and 2GB of high-speed internet, if you run out you will switch to an unlimited slower internet that you can still use for Uber, Maps and chat.
If you need more Data then you can opt for the 20$ 5Gb plan or the 25$ 10gb plan.
