買San Diego SIM card之前要知道甚麼?

  • HelloRoam eSIM從HK$22.49起,透過AT&T 和 Verizon 5G網絡提供數據服務。實體SIM卡需要到達San Diego後尋找攤位購買,排隊等候加上登記手續往往耗費半小時以上。eSIM出發前掃描QR code完成設定,抵埗後自動連接。

  • 在San Diego機場或市區購買實體SIM卡,價格不透明且常有隱藏費用。HelloRoam方案從HK$22.49起明碼實價,無合約綁定,無漫遊附加費。QR code購買後即時發送到電郵,24小時均可下單。

  • eSIM寫入裝置韌體,保留你的香港號碼並連接San Diego當地AT&T 和 Verizon網絡。實體SIM卡換卡過程需要卡針,小卡片在旅途中容易遺失。eSIM用完即止,無需歸還,無需到門市辦理退卡手續。

San Diego eSIM Coverage Guide

T-Mobile, AT&T, and Verizon all provide strong 4G and 5G throughout the San Diego metro area. The Gaslamp Quarter, Little Italy, Hillcrest, North Park, and the downtown waterfront all have excellent signal. Balboa Park's outdoor museums and gardens have solid 4G.

Mission Beach, Pacific Beach, and Ocean Beach have strong coastal coverage. La Jolla Cove, La Jolla Village, and the UCSD campus area are well-covered. Coronado Island and the Silver Strand connecting it to the mainland have reliable 4G.

The San Diego MTS Trolley system has surface coverage along all three lines. Note that the US-Mexico border crossing at San Ysidro brings your phone into Mexico signal territory if you venture close, so keep your home SIM's international settings off.

Torrey Pines State Reserve trails have signal at the trailhead parking area but can weaken on clifftop trails.

  • HelloRoam在聖地亞哥連接T-Mobile 5G, Verizon 5G, AT&T 5G
  • 5G and 4G LTE across downtown, Balboa Park, La Jolla, Pacific Beach, and Coronado
  • San Diego International Airport fully covered throughout the terminal
  • Plans from HK$22.49 with instant QR activation before your trip

聖地亞哥 eSIM旅遊貼士

  1. Border Area Signal Warning

    Near the San Ysidro Port of Entry and the Otay Mesa crossing, your phone may briefly pick up Mexican carrier signals. If your home SIM is active, your carrier may bill you at international rates. Keep your home SIM's data off and use your HelloRoam US eSIM while in San Diego. This protects you from surprise international data bills near the border zone.

  2. The Trolley Runs on Surface Streets

    The San Diego Trolley's Blue, Orange, and Green lines run mostly at street level and along surface corridors. Signal is consistent throughout the trolley network. Use the MTS transit app, maps, and messaging throughout your journey. The trolley connects the airport (via a shuttle) to the Convention Center and downtown San Diego.

  3. La Jolla Cliffs and Coves

    La Jolla's famous sea caves, Children's Pool, and the La Jolla Cove snorkeling area all have reliable outdoor 4G coverage. The village restaurants and galleries along Prospect Street are fully covered. The hike along the cliffside to Torrey Pines has variable signal on some trail sections above the ocean.

  4. Stay Connected in San Diego from HK$22.49

    A HelloRoam eSIM for the US covers San Diego from SAN Airport to Balboa Park, La Jolla Cove, the USS Midway, and day trips to Tijuana. Plans start from HK$22.49. Activate before your trip and arrive connected.

Best Time to Visit San Diego

San Diego has one of the most consistently pleasant climates of any US city. The best weather is September through November and March through May, when temperatures range from 18C to 24C and coastal fog is minimal. Late September and October, sometimes called 'Second Summer', bring warm and clear conditions to the beaches at La Jolla, Pacific Beach, and Coronado. The San Diego Comic-Con International in July is the world's largest pop culture convention and books up hotel rooms for 50 miles around; book well ahead if attending. June is marked by the 'June Gloom' marine layer that covers the coast in morning fog until noon. July and August are warm, 22C to 28C, and the most popular beach season. December and January are mild (13C to 18C) and the quietest months for tourism. The San Diego Zoo is best visited on weekday mornings. Balboa Park's museums are open year-round and provide excellent rainy-day options, though rainy days are rare.
