I don't want to be constantly switching airplane mode on & off. I have s8+ & I have noticed when signal status has LTE can make & receive calls, but when signal status switches to H call drops. No one at AT&T store or online chat can seem to help. I also don't have Enhanced LTE services option on my phone under mobile networks & they can't tell me why since they say my account has it enabled. Can any one help me?
