Lg thrive looses saved contact names.

SOURCE: Saved contacts don't appear

this might be a network thing because that is the only way it works here in Australia.
All txt msgs are number only ID

SOURCE: caller id

Save your contacts to the phone. Personalized caller ID only works from the phone, not the sim. Go to contacts then press the contact name once to select it.  Press the menu button (bottom left) on phone and scroll to 'copy to phone'.  You should see the caller name when they ring then.
 (I bought a sim back-up device so that I can keep the sim clear. If caller information is on both the phone and sim it gets listed twice in your contacts).

SOURCE: LG Shine problems with inbox display

for every contact i have i have entered two numbers in the phone book
one is their number as you would expect eg. 04 12 345 678
then
in their office number slot i have entered the number with 61 in from of it eg.614 12 345 678

that way their name shows in your inbox AND when the call you

61 is the australian code for international dialing. i guess it would be different if you lived somewhere else.

SOURCE: How do I delete the names in my contacts list?

SOURCE: new LG600g will not let me associate photos with the contact list

in your contact list, choose options and scroll through them until you see 'copy to phone' or something close. you can choose to delete or keep the contact on your SIM card too. then choose which contact you want to set the ID for.
