My sister-in-law signed up with Smarty's 40GB data plan 14 days ago and she is a very light data user and yet the Smarty App states she has used 34GB of her allowance. Fortunately she is using a TP-Link 4G Router which independently records the data used. I will be paying her a visit soon to examine the Router info, her devices and general setup. For now I am suspicious as to the validity of the data usage Smarty reports via their App. Call back in a week for an update.
