AT&T vs WOW in Charleston
AT&T fiber is faster and more widely available in Charleston, but WOW cable starts $10 cheaper each month, so it comes down to speed versus the lowest bill.
AT&T is the stronger pick for most Charleston homes, winning on both speed and reach. Its fiber tops out at 5,000/5,000 Mbps with a 99/100 speed score and covers about 86% of the city, and its $35 starting price undercuts what you’d expect for that performance. WOW’s cable maxes out at 1,200/50 Mbps with an 88/100 speed score and reaches roughly 65% of Charleston, but it starts cheaper at $25. Choose AT&T if it’s on your block and you want the fastest, most future-proof connection; choose WOW if you want to save a few dollars or AT&T fiber hasn’t reached you.

Check my addressFrequently asked questions
is AT&T fiber or WOW available at my Charleston address?
AT&T fiber reaches about 86% of Charleston and WOW cable about 65%, but availability varies block to block. Enter your exact street address on each provider’s checker to confirm which one actually serves your home before comparing plans.
which is cheaper in Charleston, AT&T or WOW?
WOW starts at $25/mo versus AT&T’s $35/mo, so WOW is the cheaper entry price. These are promotional starting rates, so before signing confirm the post-promo rate, equipment fees, and any contract terms, since the lowest advertised price isn’t always what you’ll pay long term.
is AT&T or WOW fast enough for gaming, working from home, and 4K?
AT&T is faster, reaching up to 5,000/5,000 Mbps (where available) with a 99/100 speed score, versus WOW’s 1,200/50 Mbps and 88/100. Both cover 4K and basic work, but if you upload large files or game competitively, AT&T’s symmetrical speeds are the safer bet, so check which speeds are offered at your address.
