Answer
Wi-Fi at Ocean City area campgrounds is often marketed but congested on peak evenings when every site streams at once. Cell service is generally solid on the mainland; Assateague can be patchier depending on loop and carrier.
Download maps, tickets, and kids’ videos before you lose signal. Do not rely on camp Wi-Fi for work deadlines without a hotspot backup.
Ask the office which loops have the strongest coverage when you check in.
