A:AnswerUnfortunately on unlocked phones most carriers block that feature due to the differences in how their networks handle the handoff between their cellular networks and Wi-Fi. If you want to be sure the carrier you are currently with will support that feature you'll need to give them a call at their customer care number and ask. If they do support that feature for your unlocked phone they should be able to provide instructions on how to get it running. Based on personal experience the answer has been no in the past.
If that is something you really want to work guaranteed the safest option would be to purchase the carrier specific version of the Samsung A51 as it will have that feature enabled by default since it's locked to that carrier.
A:AnswerAt present this phone the A51 5g is not compatible with Spectrum mobile. Spectrum mobile primarily uses the Verizon network and this phone is not compatible. A similar model is sold for Verizon the A51 5g uw. Theoretically you could use the phone for Spectrum and receive 4g service but they will not offer you a sim card card based on your IMEI number.
