Sanyo katana can't receive a signal

A PDF users manual is located here: http://support.sprint.com/global/pdf/user_guides/sanyo/katana_ii/katana_ii_by_sanyo_ug.pdf just copy and paste into your browser window.

I looked at the manual for your phone, as of right now it doesn't seem to support the ability to block phone numbers. Though I would recommend calling you wireless providers customer service department and they might be able to help you.

If you would like an online copy of your manual, it can be found on sanyo's website

Let me know if you have any more questions.

Thanks,
Mike

If you mean unlock it to another carrier, you will either have to purchase an unlock code on the internet or call your carrier and request an unlock code. If you mean unlock it beacuse it is protected by a pin, the only way to get around that is by resetting it.

Friend, Check the flex connection from the keypad interface then clean the board or the doom with pencil eraser

I think the your screen may have given up due to long use or due to miosture. This may be fixed by changing the LCD sreen from your mobile's authorized dealer.

If you call customer care or possibily tech support you can request text messages that were sent or received, and there is a fee for that I just dont know how much.

The internal antenna is damaged...this might have occured from an accident or misuse...the antennas is not strong enough to receive your providers signal
