3G issue

[zacksac]

Hi , 

I have experia xa dual  and 3g is very troublesome it does not provide good internet always keeps going back to 3g from H+ . I have checked same sim on my other phone expera zr where 3g is good .

I have even flashed earlier stock rom of marshmellow as i thought new update might be the caouse .

Volte internet is fine and constant only problem is with 3g reception . I have also checked online and few others also have this problem . I want to know for any solution  or will it go away with anroid 7 ( also not released yet for india )

Thanks.

Settings > about phone > status > signal strength > what do you see? 

this is most likely a network coverage area, how old is the SIM card?

[zacksac]

I see that you are not getting the point .

I have used the same sim on my experia e1 dual , and experia zr and dont have any problem in the internet only on experia xa 3g signal is worst and breaks ... driving me crazy even the naugat update is not comming as a result I have to use my experia e1 dual to browse the internet .

@zacksac

could you answer my questions? 

[zacksac]

yes

-85 dbm 14 asu on experia xa  .The sim is bit old (does this mean xa does not support old 3g sims ? ) .

On experia e1 dual signal was -87dbm 13asu .

Also on both phones I had set network to wcdma only .

Also I keep swapping the sim between phones to check internet  . Never got problem on experia e1 dual and always there was problem in experia xa .

Also let me try to describe the issue on experia xa .

The network bars are there also h+ and 3g sign but when browsing h+ is there fore few seconds then it goes to 3g then again to h+ and this is in loop . Also when in 3g symbol it feels like no internet . The same when downloading .
