[OzanBaris]

Hi , Its OzanBaris from Turkey !

I bought Sony M4 Aqua. But i have a problem about LTE ,3g and 2g. When i change to LTE its working but not everywhere. But when i change it to 3g/2g my sim card does not work ! What can i do for this situation? 

I had a tons of conversation with my operators and sony turkey. They are not changing my mobile. Its not about a month i bough it. I need a help !

@OzanBaris

Based on your description, you probably have poor LTE coverage, as for 2G/3G, you might want to get a brand new SIM card, also, make sure that your phone it's compatible with your carrier's bands.
