A confused senior citizen I have an Android Samsung Galaxy J5 phone with SIM card slot No 1 with a Reliance Jio sim and SIM card slot no 2 with a BSNL 4G SIM.

On my BSNL line I do not have data but only for incoming/outgoing calls and other usual applications. I also have roaming and international calls.

On my JIO line I have usual Tariff facilities including data and national roaming.

What do I do to get the maximum out of my two SIM cards and what settings do I put for them??

Please advise as I am really confused.

JIO only has a 4G VoLTE network and wouldn't work in 2G/3G. Does your phone support LTE + LTE may not be supported in your Galaxy J5. See if you can manually set your network and search for the BSNL sim from "Dual SIM settings".

You will have to switch primary SIM from JIO to BSNL for this as your phone doesn't support LTE+LTE. The JIO sim will probably lose signal when you switch BSNL to be the main SIM.

Also, you cannot use Mobile Data for both SIMs at the same time
