Editing contacts on LG G8 ThinQ phone

[AVONLADY53]

The state of New Mexico will be going to 10 digit dialing in October.  So if I want to call my husband in the next room I will have to dial the area code.  All of my information/data/etc was transferred from my old phone to my new LG G8.  For some reason many of my contacts do not have the edit button so I am unable to edit them on my phone.  I made all the changes in the Verizon Cloud.  Not knowing enough about this "high in the sky technology" (unable to get a good Google answer either), does the Cloud sync back to the phone?  If not, how in the heck do I edit my contacts?  I would like not to delete about 300 of them just to reenter them with the stupid area code.  Uggggh!!!!

Hello AVONLADY52, we know how inconvenient having to change your contacts can be, and we're here to help! Adding the area code through the Verizon Cloud is definitely a good idea. The Cloud will update your contacts, so you don't have to worry about that. ~Baldo
