My lg e975 does not read any sim card.how can i solve this problem?

The LG Optimus Big LG-LU6800 is a CDMA (Code Division Multiple Access) unit. A network (usually a Korean network) connects directly to the unit using its unique code. It doesn`t have a sim card slot. If you want to use it, you need to contact a network provider and register your LG LU6800 for it to get signals in your area, either by prepaid or postpaid service. The device can still be used but without the network call and messaging feature since you will not be getting signals from a network unless you register it. There is a rumorred Mini-sim card slot on a model of the unit. Users use a micro-sim card instead for those unit since there is an issue fitter the prior sim card size. If you are unable to find the sim card slot (visible when you remove the battery) then you most probably have the CDMA version.

Hi, maybe there's a problem with the SIM card or the SIM card is not compatible. Also, your phone might be network locked. You may check that in the following guide for LG phones: http://www.fastgsm.com/en/page/how-to-unlock-lg-gt540-optimus-gs290-kp500-cookie-gd510-pop-ks360

becauyse it doesnt recognize it... clean the contacts on the sim card, and the phone, if theyre worn.. you could need a new sim card, also simcards can **** out after a couple years... mmine only took 5, might need to order a new one..

plse reive gprs setting plse call your sim card customber care

you first need to know the network coming with the first before buying it...and what network AT&T works on.

for example

LG KG800 works on these networks

850/1800/1900 or 900/1800/1900...you need to look at the box to see which network your phone comes with.

If i am not wrong E6 of Motorola was launched recently , U will need to approach Service Center . As no one Online will be able to solve u r problem. The problem is between u r sim reader & Main Circuit , so it is better to approach Service Center
