xfer contact info from basic phone to android phone

If it's a basic flip-phone, those can usually save contact details to the SIM card, and then put the SIM in the new phone, and import contacts from it. Which is basically the old-skool way of transferring contact details, before the advent of smart-phones.

 

Does the phone software have any way of exporting the contacts? Does it come with any utility to back them up (ideally to a computer, but even to Verizon servers would do if there was a way of you exporting them from there)?

Or does the phone software allow you to share contacts via Bluetooth?

I can only ask questions because I know nothing about this particular phone, and dumbphones' capabilities vary between models.

 

Pen and paper

 

Those should be vcard format, which is a standard. If so the Android device should have no problem with them (and it would be stupid of LG to use anything else).

The real question is whether it will let you send your whole phonebook at once or only one contact at a time? I've owned both sorts of device in the past.

 

This might work out but I'm only tentatively suggesting this will work for you. Check out 'BitPim'

Way back I had a LG flip phone that wasn't in the list of supported devices but it still worked out:

And don't be surprised if the contents your are able to pull off that flip phone will be in file formats that you might have to convert into usable file formats that can be imported into a smartphone.
