Looking For A New Phone

Venomx999

Family member wants a dual sim active phone ( both sim cards on at the same time )
One sim for work and one sim for personal. NOT DUAL SIM PASSIVE

Must have both sim cards running at the same time
£300 budget
Must be unlocked

Any ideas ?

Thanks

The huawei p20 light. Is it dual sim active? So both sim cards can run at the same time?

Update : were going to go for the honor 8x
