I bought a LG CDMA Multi-links Fixed Wireless Phone LSP-3510 sometime ago. The network on it is totally OFF. The phone has been sadly rendered unusable for me but there is a slot for Data connection for which I now need to buy a Data Card/Kit to get it connected to my Desktop PC in my Home office.

The number written at the back of the phone is: PN: TWLL 0033602.

There is also a slot where to insert a "R-UIM" sim card. I inserted a GSM sim card but it failed to work.

Please, where and how can I buy the Data Card/Kit for this phone?

Besides, how can I find ANY network (CDMA or GSM) restored on this phone in order to resuscitate it?

I would appreciate your kind support.

Thank you.
