[Q] SGH-I337 Won't Read SIMs
I just purchased this phone used. The previous owner reported this phone for having some "minor" software issues, such as freezes and losses of sound.
This phone is on stock MF3 ROM. From what I see, tt is having some random issues, mainly random freezes and I have to hard shut it down. I successfully rooted it with Kingo, but this does not change anything.
Today I got some time to test a couple of SIM cards, one active AT&T one and a Verizon SIM. The phone failed to read either cards. It just reports "no SIM card".
Since this phone is on MF3 ROM, there is not much I can do to re-flash with any other ROM. Do you think this is a hardware issue? or just software issue? Thx.
