No signal for my two simcards after an update.
Model Name: Asus Zenfone Max M1 android version 8.0.0. ASUSXOOPD - WW_ZB555KL_15.00.1810.87_20181102
did the network reset, the factory reset and still there is no signal. With other phones, they are working just fine.
Please help. This phone was given as a gift and yet, after a few weeks of usage, this happens.
