PUK code is the code that is used to protect your SIM Card this is the card that stores your telephone numbers, pictures. You need to call your cell phone carrier and advise them that you need your PUK code to unlock your phone. They can give this to you and advise you how to use it and then you will be able to change the code and use it as needed. good luck

I love my cell phone and now I don't have a land line at home. Like anything, I think it can be abused or overused. I think its very rude to be dealing with a customer or walking with someone and be on the phone with someone else.

It depends on the cell phone and manufacture, service provider. When it says that it usually means your SIM card isn't working correctly. Check your manuel and see if there is any other problems it could be.

Yes you can use your cell phone as a modem.  You need to find the USB cord that will fit your phone, also the USB drivers are required.  You will need to look to your telephones menu and see if it has DUN capabilities.

Once my sister and I had just got new cell phones from england  as a christmas gift which we weren't suppose to see but my mom had taken them to the house to gift wrap them and I found them. I took them out and noticed that mine had no sim card and took out her's and put it in my ceel phone and used all the minutes even when we had gotten our gifts I pretended that it was mine and continued using it  and up to this day she doesn't know that it was her's and the saddest part was that I had two sim cards and she had none and I had lent her one but the I took it back andshe ended up with none I was so mean.

Yes and yes and yes...you can use a cell phone but it is SLOW at 14.4 kbps. Yes it uses your minutes. Night and free depends on your cell phone provider. YOu need the dial-up number of your isp, how else would you dial to use your phone?\nThere are many faster options such as wifi or verizon wireless broadband. I have used a cell phone in a pinch. BTW< you need a cable that goes from your cell phone into a USB port in the laptop.

Text back services are proving to be popular, for information on the weather and market prices.  A company called Tradenet operates in many African countries giving market prices on yams, cassava, rice...  In Ghana Busy Internet is planning to start top-ups to its internet and home ISP credits via the 'services' menu in a Areba (a GSM operator) sim card.  The 'services' menu is usually not much used, but operators could make much more use of it.  Ringtones haven't picked up in West Africa, nor have data services, apart from a few business persons.  \n\nBelieve it or not, the most added value service is the fact that you make sure that your recipient doesn't pick up you call.  I.e. just like in Europe in early days of mobile phones, you just ring once or twice, and hang up.  It can signify 'hi', 'I care about you', 'I'm awake', 'I'm on my way' or 'Call me back'.
