US operator AT&T, a traditional partner of Apple, is close to enter new 4G LTE micro-SIM cards for its customers, although for now it does not sell devices that use such cards to connect to LTE networks. The management of AT&T organized a meeting with the store representatives and explained to them that these cards are compatible with both 3G and 4G LTE networks and the Nokia Lumia 900 or even the iPad 3 tablet could be the first devices that could use.
Now, one of the possible explanations for this is that the new micro-SIM cards are meant to be installed in the upcoming Nokia Lumia 900, which as we know will fly on AT&T's 4G LTE network. However, can you think of another smartphone that uses micro-SIM cards? The iPhone 4S, of course, and its successor, which might be known as the iPhone 5, is most definitely going to use micro-SIM cards as well. Unless Apple decides to jump straight to nano-SIM cards, that is.
It has already been rumored that the iPad 3 will come with a GSM chip capable of working on LTE networks but I explained it here that I for one do not believe in the possible implementation of compatibility with such networks except in the case where the tablet will come with a larger battery. Taking into account that AT&T is one of the operators that receives priority in the sale of iDevices and launches the first SIM cards compatible with new technologies from them, the theory of an iPad 3 tablet compatible with LTE networks takes shape. If iPad 3 will be compatible with LTE networks, then iPhone 5 will work safely on the same kind of networks.
