AT&T has officially announced that its 4G LTE service is now available in Philadelphia, PA and Wilmington, Delaware. AT&T’s LTE service will provide faster service and response time, efficiency of spectrum, and compatibility with “cool new devices.” Two of the hottest phones out there right now – the HTC ONE X and the Samsung Galaxy S III – are compatible with AT&T’s LTE service, and they would definitely fit into that “cool” category. AT&T does offer shared data plans, but with this blazing LTE service you may be better off hoarding a plan all to yourself. Are you rocking AT&T LTE service in either of these areas? Let us know of your experience thus far.
