Instead of ordering a phone on line can i come do it in the store and pick it up there

Yes

I couldn't because there was a problem with the address on my account and it threw a snag in everything but most people can got to either the Greenville or Anderson store and start mobile service and walk out with a phone

Yes that's what the spectrum store is for Anderson SC you pay bills by a machine now just don't forget to sign in when you get there

Yes they have them there

When I purchased my new phone about 6 months ago, you could. They may not have the same selections there ( colors, models, storage capacity), but they do have a fairly large selection in the Anderson store.They can also help you transfer anything you want transferred from another phone ( messages, contacts, pictures, etc. ) in the Spectrum store.
