If you got your s8 from either bell or mts it will only read one sim card, even if you had a dual sim card tray. There is models of the s8 that are dual sim but those are international models and not sold by any carrier in Canada.
If you had a dual sim s8, it is dual sim standby. Meaning if you are phoning from sim 1 then sim 2 is unreachable. Also, only one of the sim slots is compatible with 3g/4glte.
