LG 550 mobile software problem
I have some suggestion and also looking forward to help and answer your question. As I read your question regarding connecting of your mobile LG 550 into computer to tell you the truth you must have a CD software to be install in your computer to connect your mobile using USB without this your mobile will not be compatible in you pc.
You can also ask your Cell phone provider about CD software if its free and you can buy and also for assistance. I have also suggestion you can also connect LG 550 via Bluetooth but take note you must buy also a device for Bluetooth and install in your pc. You can buy this at PC hardware on your place and also ask a guide in technician for installation if you don't know.
I hope it will work for you and help to answer your problem.
No. All the handsets don't come with the CDs always. Sometimes the software remains built-in the handset. You connect the handset with your laptop and then install the software in your laptop. Then you will be able to operate your handset through your Laptop.
But if the software is not built-in, then it must require a Software CD. If you do not have Software CD, your alternative way is INTERNET. Just search online by your handset model no. for your software installation CD. You will find the compatible softwares for your handset. Just download and install it.
