In telecommunications, the terms multi-band, dual-band, tri-band, quad-band and penta-band refer to a device (especially a mobile phone)
To check if a handset is dual band, tri band, or quad band, go to the device's settings and look for the "About Phone" or "Network" section. There, you may find the specifications or details about the supported network bands. Alternatively, you can refer to the user manual or the manufacturer's website for the exact model to confirm its band compatibility.
