Why my smartphone switch back to 3G network?
Hi guys,
I want to know what is the problem I use Samsung Galaxy S5 and Airtel network with 4G for internet use. I can see clearly on my Sim network notification that my 4G network switches back to 3G or 2G again an again. Is this because some locations does not have 4G access or say they don't have 4G available in some location please let me know.
