today i realized. if you use single sim on your device you get good network speed .not best .....but if you use dual sim then the problem start with signal strength and speed on both network.
i see some articles on reddit and quora .the users telling that Samsung phones is not good for dual sim ...yes if you are in city there is no problem. but if you are in village, rural area then problem started .so if you are at rural area like me then use only one sim .thats it ....remember one thing after doing this you get much better speed then before. not best .
2nd method (my personal fav)- 2nd method is for dual sim users like me .go to playstore search》 Samsung band selection 》install 》open the app》go to the left side setting 》choose band option 》now choose best band according to your area and network 》enable it . ....
FOR JIO 》lte B3/lte B5 (TEST BOTH THEN CHOOSE ONE)
FOR AIRTEL》lte B1/lte B3(TEST BOTH THEN CHOOSE ONE)
FOR VI 》lte B3/ lteB1 (TEST BOTH THEN CHOOSE ONE)
after locking specific band you clearly see the deference..
thats how you can improve your network. there is no others better way ..remember one thing if you are facing no network on you sim .open the app and disable the band selection ..
