Error while searching for networks

[algova73]

Hello, everyone,

Please bear with me as I am not very savvy with cell phones. I recently bought from everbuying DOT com a phone (reference I9400 running Android 4.2), kindda like a clon of the SIII; it was supposed to be unlocked and ready to go on any AT&T and T-mobile networks. The reason I bought this phone was because I used Metro PCS and got tired of the loss of signal and other things; I bought a SIM Card from Net10 which run on the AT&T network and from what I've read online it may even run better that AT&T itself.

Anyway, I put the SIM card in the phone and it gives me the error "Error while searching for networks" and it doesn't show any networks to choose from. I know the SIM card is working fine because I put it in a friends iPhone and in another friends Samsung S and the SIM card worked. I put other SIM cards in my new phone and it does not recognize them.

I know it must be something with the programming of the phone but I am leaving on vacation in about 15 days and by the time I send it to China and get it back I won't be able to have it until I return from vacation, and that is IF they exchange it because now I cannot find the box

I do NOT know how to flash cell phones and don't even understand what ROM is, so if you could PLEASE send me step-by-step instructions, kindda like "Android for dummies" I would really appreciate it.

I love this phone but it is not working, any help you can give me will be GREATLY appreciated.

Thank you all.
