This makes the browser display a login prompt, but it doesnât display any other text thatâs in the response. (It only displays that response text if the user clicks âCancelâ.) When the user enters some credentials, the browser resubmits the same request to the same URL, plus it also adds this extra header: Authorization: Basic username:password.

Sim card hold contacts, so pretty much everything will remain on your phone besides your contacs and your MEID which is your phone number.
The SIM -- that tiny card that holds your contact info and account information that you find in your GSM handset -- is a 15 x 25mm plastic card whereas the new Micro SIM (also known as a 3FF SIM) is a diminutive 12 x 15mm, about 52% smaller. Needless to say, it's not physically compatible with your current phone.
