I've been using Jio for past couple of months and been having an issue where i dont get any signal after finishing my data per day for 2-3 hours then used to come back . today it again happened but my signal isn't back and its been a day already . i've tried doing *#*#4636#*#* and changing the preffered network ,turning radio signal off and back to on , restarting phone and changing sim slots . I'm on panasonic eluga switch please help.
