If you’re in a area where LTE signal is weak or there is no LTE signal in that area,
The phone will automatically switch to 3g or Edge.
On Meizu you can set up LTE Only
But if you are in an area where LTE is not available,
the phone will say no service because it is set on LTE Only mode.
If it is set to gsm/wcdma/lte auto it will switch to 3G when you’re in an area where LTE is not available.
Iphone is set to default-auto when on LTE,
and you can’t select Lte only,which is a good thing I think,
because if you have weak LTE signal it will drain the battery.
