Works good if you do not switch SIM Cards – DataMan Enterprise Review

I will give it higher stars once app is improved to recognize when people switch SIM cards to Lee track of data usage for each SIM card used. If you travel often and switch SIM cards it continues to add data usage on amount of data used. It does not automatically recognize how much data was used on each SIM card which it should as this makes it easier for travelers who travel often and switch SIM cards while traveling. Here in Asia people travel often between China,Taiwan,Hong Kong,Thailand and Japan. Some cards are pre-paid and others are post paid but either way they usually have data caps on them and the app should allow people to input data cap for each SIM card/carrier and the app should do the rest from there by its self. This app does not do so.
