Service Provider: Straight Talk
Device Carrier: Samsung Galaxy S10plus from Spectrum
I just recently purchased a Spectrum Mobile Samsung Galaxy S10+ from a 3rd party. The individual had the device listed as Unlocked, however after taking the phone home and trying to use my Straight Talk Sim Card, the phone was locked to Spectrum Network, and I had to have the phone Unlocked for my Straight Talk carrier to be used.
Set up the APN settings for Straight Talk and receiving Data with no issues.
This phone (from Spectrum) does not have WiFi Calling or VoLTE options in the Phone, Mobile Networks, or in the Wifi Settings.
On my S9 Plus, I bought it directly from Samsung, Unlocked, and had no issues with WiFi calling.
Is it possible to change the phone's firmware to include VoLTE or WiFi Calling or is something related to the device's hardware?
Will try to call Straight Talk to see if SIM is fully provisioned.
