Connectivity and Technology
The J220 was built to operate on GSM networks, supporting 2G bands in specific regional configurations (GSM 900/1800 for the J220i and GSM 850/1900 for the J220a). This connectivity layout makes it primarily a device for calls and text messaging, with no support for GPRS or EDGE data technologies. As a result, it lacks modern features such as Wi-Fi, Bluetooth, USB connectivity, and a positioning system—emphasizing its basic utility. For users content with SMS, EMS, and MMS messaging, the phone offers a rudimentary WAP 1.2.1 browser, which is limited by today’s standards but could cater to basic browsing needs of that era.
