What is the backward compatibility strategy? Will new OMH SIM cards work with legacy devices?
Yes, the new OMH SIM cards are fully backward compatible with legacy devices that use CDMA R-UIM cards. Legacy devices treat OMH cards exactly the same way they treat legacy cards, so that there is no impact to the user. There are OMH operators who will continue to use the same size cards and ones who will use OMH adoption as an opportunity to upgrade their card size. Technically, the amount of additional card memory required to store additional configuration information is relatively small. Of course, it depends on the amount of available memory on an operators current cards.
