Hi, I have a Samsung Galaxy S4 a T Mobile (SGH-M919) version which is factory unlocked and I cannot connect to my data connection. I cannot use my 4G LTE capabilities and it only uses the EDGE connection but still cannot connect. I had an iPhone before which can connect to 4G, 3G, and EDGE. What can be the problem? Help please. I am based in Cavite and I am using a new Globe prepaid sim. My surfing promos became useless.
