What people are saying

Rated 1 out of 5 by from Terrible Option I bought this like a month ago, due to COVID 19, there were no other options either in Best Buy or T-Mobile, It was this or a Motorola, Everything works more or less according to the price, but all the pairing options via Bluetooth or Wifi are absolutely unstable, it connects and disconnects all time, and I mean every single minute, Hopefully, there's an upgrade or something to do.

Rated 2 out of 5 by from Cdma phone Phone cannot connect to google maps location sharing, does not connect to internet when not connected by wifi. In ad there is no mention of the network the phone is made for., and that is Cdma and that is outdated. This phone is most likely surplus and being sold to make room for 5g with no mention of yesterday's technology.

How do I turn on Wi-Fi Calling?

Asked by: Trancebam
You will find the instructions for how to turn on Wi-Fi Calling on on page 92 of your owner's manual for the LG K51™ | Boost Mobile, Model # LMK500UM3ABMUTN. As per the instructions, On the settings screen, tap Network & internet > Wi-Fi > ⋮ > Advanced Wi-Fi > Wi-Fi Direct. • Nearby devices that support Wi-Fi Direct automatically appear. Select a device. Connection occurs when the device accepts the connection request. Your battery will drain faster when using Wi-Fi Direct...^IFV
