Question about Cell Phones

1 Answer

I had a black jack sgh i637 for a few years. Loved it. So when it broke I decided to get a new one. I went to ebay and got an unlocked one (I live outside of the usa). After a week of using the new phone it started. It just shut off one day on me as I was charging it. It was plugged into my laptop. When I tried to turn it on it would say 'Samsung' for a few minutes then the Samsung would split in half and then refresh and that is all it would do. So I removed the battery and sim for different intervals of time and tried again and again. After an hour removal It worked fine. Then it was one and off for a day or so. Finally it worked, I was on a call with my wife and then it happened again. I changed the battery to the new one (still used my old one) and now it is frozen on the 3G loading display. What the hell is the deal? Also this new one operates much slower than my old one. What can I do?

Can i brows web through pc suit with lg kg 300? is it advisable? from where i can download it?

I just checked the specs on your phone. It looks like your phone does not have the capability to access the Internet through PAM (Phone As Modem). As such, you cannot connect your computer to the Internet by using your phone - which is also called 'Tethering'. (If this is your question.)

There are many other phones which you can use to tether your phone to your PC to surf the Internet. However, only a few cellular providers allow this. The ones that do severely limit both the bandwidth (speed) and the amount of monthly data usage when tethering.

If you do decide to tether I STRONGLY advise you to use the New Google Chrome Browser on your PC when you surf the Web. It's much faster (which you'll need due to the decreased bandwidth).

When you look for a phone you can use to tether, (like the Samsung Jack SGH-i637 for example) look to make sure it has an Internet sharing option in it's installed programs. (I use my Samsung Jack when I tether my laptop to the Internet when I travel.) And, I use Google Chrome as my browser when I do.
