Hi Hotlink,
I currently have two of these tablet plan SIMs. One for a Windows Tablet (micro-SIM) and another one in a 4G MiFi device (Aztech MWR647) (Full Size SIM). As mentioned by user Renetch above, there is a need for users of the tablet plan outside of Android and Apple devices to be able to at least check the balance of their accounts.

Constantly pulling out the SIM to put into another device to check the balance is unacceptable. Furthermore the MiFi unit is using Full Size SIM, I really do not have a Android/Apple device with Full Size SIM anymore ...

Do put up a web-based solution for the users of this tablet plan to be able to check the balance of this plan. Thanks!
