How to illegally reactivate a turned off cricket LG B460 flip phone with its sim card that was issued to me when I got the phone?

This happened to me too. A temporary fix is turn off your phone and put it in front of a really cold air conditioner for about ten minutes. Then turn it on but make sure you keep it in front of the ac to keep it working. What happened is your sim card reader has a thermal problem so you will need to take it in unless you want to spend all your time in front of the ac (which will get expensive...)

yes you can because i have my lg enV2 with cricket and the can flash it fully

SOURCE: Insert sim card issue

just insert another sim card and check whether that sim card is working. also put your sim card in to another phone and check whether it is working.

SOURCE: my lg vu does not recognize the sim card.

When a SIM works in other phones and no other SIMs work in the particular phone, there is a phone issue. Somehow it has become corrupted and it will need replaced promptly. If purchased new from AT&T less than one day ago, it is under warranty as long as there is not liquid or physical damage. If purchased refurbished from AT&T less than 90 days ago, it is under warranty as long as there is not liquid or physical damage. If neither of these apply and you have insurance, use it and there will be a $50 deductible applied to your next bill. If not purchased from AT&T, seek replacement from ebay, craigslist, or a gophone (put your sim in the phone... it will have your phone number, contacts, and information and you won't have prepaid service).
