Why do I lose 3G OR LTE, and only get EDGE after my iphone 5s disconnects automatically from wifi? Why do I have to switch airplane mode on and off to get 3g or LTE back?
iPhone 5s, iOS 7.0.6, 3g and Lte issue!
Who is your carrier?
What signal strength do you have on 3G and LTE?
Are you in a rural area?
My carrier is Zain in Saudi Arabia.
I have Full 4g bars.
I live in mid-size city.
It doesn't always happen, but from time to time.

You can try these:
Reset network settings- resets the network profiles on the phone
or
Reset all settings- resets every setting and preference on the phone
Otherwise try, Pressing and holding the power and home buttons until the apple logo appears
Lastly, you mentioned 4G your reply, and your original post has 3G and LTE. Please note that LTE and 4G are two different communication standards, their identifying terms are not interchangable.
Only EDGE!
