Sorry i don't know the exact phone model but as much as I can gather from dad in law ...
He says he gets no XT reception rurally. He swaps the sim into an el cheapo XT branded wildfire S and gets perfect signal. Sounds strange ...
He puts in VF sim rurally and gets perfect signal ... just not XT
That's what he says ... any ideas?
(phone is bought in singapore and has had OTA ICS update)
