Chennai consulate interview mobile phone storage options

[joyan]

Have to go to the Chennai consulate for a 221g interview. Will be arriving in Chennai alone via early morning flight and leaving in evening so don’t have any hotel. What are the current available options for storing the mobile phone while at the consulate. Anyone with recent experience please advise https://routerlogin.uno/ https://192168ll.link/ .

Also if you had a 221g interview how long did the whole process take? And was passport returned by same mode as originally selected (mine vac pickup delhi). Thanks!
