Do I need one for every phone??

You only need one of these devices per phone number or phoneline. One unit will protect all phones and or extensions on a phoneline. Regards,

Yes, this is only for the hardware. Just like your phone, it's just hardware, won't work without a plan.

I have bought three. Having bought that many means I've had to remove it several times. I will say no issue with application or removal. I had to have the phone replaced for various reasons.

you do not need one . the lens is hard to damage . this phone does actually need any protection , more likely a grippy cover. Look at the destruction test on youtube

Screen protector is a must for all new phones (IMHO) however I don't think an extra layer of protection is needed besides the case. This case will protect your phone from accidental drops & slips.

I don't use it for my phone either. Like the other respondent said, you have to have a phone that has a little hole somewhere on it for such things. I use it for my Bluetooth earpiece. I guess that's a little odd, but I lost one before (a Bluetooth earpiece), so this way, I never lose it.

Yes. Your phone or any other electronic device you have. It's an excellent product.

No, you only use one at a time. The others are spares so the touch stays sensitive.

I don't know that it 'requires' one. I'm not using one on mine. So far no problems.

Probably not. It's a snug fit without a case on the phone. Adding one will probably not work.

I use it for everything (Samsung tablet, Windows phone, and LG phone, etc.). No problem.

You can use one for all of your lenses. it comes off with your lens when you take it off the camera, but if your in rush to change lenses it might be beneficial to have one on each lens

You will need only one. I thought the of the same question before I bought mine. I have bought two, though. I have one at home and one in Afghanistan.

yes, siNOrmally you need one than uses a sim card (like those used by AT&T;) but not those that you cannot insert one (such as Verizon)

Yes...attach one on the phone behind the phone batterie and one on the inside of the batterie cover....will work better.

Not necessary. Most people that I asked do not use one. I bought one but have not used.
