no signal

Have you powered off the phone and taken the battery out yet? Sometimes it's a good way to handle the phone problem. If it doesn't work, you should go to the cellphone shop for help.

mmh in some cases when you have not signal on your mobile phone the problem is related to the general signal of your operator may be related to your area you know some upload on the mobile net or problems as well!!Surely fi your situation endure too much you will have the doubt that your mobile phone is wrong and so you can check up it!!

I've had that happen with my cell before. It is usually just because there is a tower down somewhere or something. I wouldn't worry about it at this point. I would just call the carrier and let them know of your concerns. They may have some info. on the subject.

It depends on the location sometimes if it's not the phone itself. I've had problems like that every now and then but it's because of the place I'm in at that time.
