I kept connects 3G rather than 4G
I'm using Lg V50s thinq.
Prepaid sim for 15gb, $40 plan.
The plan suppose to connect to 4g but my phone keeps connect to 3G.
And when I try to add the Apn setting and restart the phone, the message of
"Your attempt to connect to data service was unsuccessful".
So when I went to the At&t store, they kept saying that my phone is not eligible for at&t.
However, it's new series of lg, can't be not eligible.
Currently, I'm using 4G plan in 3G speed.
I need immediate support.
