Hi i recently purchased a Xiaomi mi A1.
When i first placed my sim card in i received 4g but i could only text and call and my data would not work. i called up my service provider and they made me make a new APN and that got me internet but i lost 4g and only got 3g. i then started exploring the settings and found Set Preferred Network Type and messed around with those setting. now my internet drops out everywhere. Does anyone know what setting i should pick for Sydney Australia'
Thanks Jack
