買 eSIM 出國，落機即上線，覆蓋 185+ 個國家，免昂貴漫遊費

HelloRoam 在 185+ 個國家連接 204+ 個本地電訊商網絡，為每個目的地提供穩定的 4G 及 5G 連線。所有數據方案符合 GSMA SGP.22 安全標準，確保連線品質與安全。香港旅客在日本、英國、歐洲及東南亞均可享受與當地居民相同的本地網速，而非慢速旅遊網絡或共享 Wi-Fi。

HelloRoam 方案為數據方案，不包含語音通話及短訊服務。數位流量卡負責海外數據，你的香港原有 SIM 卡繼續接聽來電及短訊。WhatsApp、FaceTime、Zoom 等網絡電話應用仍可透過 HelloRoam 數據正常使用，可免費致電家人。如需接聽本地號碼來電，保留原有 SIM 卡即可，兩者互不影響。

數據方案一經安裝至裝置後，不可轉移至另一部電話。這是 GSMA eSIM 規格的安全設計，防止未經授權的設定檔複製。如果在外遊期間換了電話，請聯絡 HelloRoam 客服處理。購買前請先確認裝置相容性，iPhone XS 或以上、Samsung Galaxy S20 或以上及 Google Pixel 3 或以上均支援 eSIM。

HelloRoam 讓數碼遊牧族在 185+ 個國家保持穩定連線，每個目的地毋需重新辦理 SIM 卡手續。無限數據方案適合每日需要視像通話、大量上傳及熱點共享的重度用戶。所有方案集中在一個 App 管理，數據用量一目了然，隨時補購數據。對於需要長期在多個國家工作的香港遠程工作者，HelloRoam e-sim 提供靈活的預付費方案。

HelloRoam 採用 GSMA SGP.22 加密標準，所有設定檔均受到行業最高安全規格保護。數位流量卡比實體 SIM 卡更安全，因為沒有人可以實際取出並複製。HelloRoam 不儲存或分享你的通話或數據內容，亦不收集位置數據。如需在連線時額外保護私隱，可在裝置上加裝 VPN App，對數據流量進行端對端加密。

Samsung Galaxy S20 或以上型號均支援 eSIM。在電話設定中掃描 QR code 即可安裝 HelloRoam。Galaxy 裝置支援雙 SIM 卡，你的香港號碼照常使用，HelloRoam 則提供外遊數據，前往日本、韓國及歐洲等地都能保持穩定連線。Galaxy 裝置通常為出廠解鎖狀態，可直接使用 HelloRoam e SIM 數據方案。

HelloRoam 方案到期後，數據自動終止，不會自動續期，亦不會收取任何額外費用。方案到期前，你可以透過 App 或官網購買增量數據，即時生效，數分鐘內恢復上網，毋需刪除或重新安裝設定檔。如果旅程延長，只需在同一 App 內補購方案，操作簡單快捷。所有方案採用預付費形式，完全按照實際需要付費。

HelloRoam 由 FutureSyncs Ltd. 正式營運，是合法的旅遊數據服務平台，覆蓋 185+ 個國家及 204+ 個電訊商網絡。所有方案符合 GSMA SGP.22 國際安全標準，提供 180 日退款保證及 24/7 全天候客服支援。HelloRoam 於 2025 年 8 月正式推出，現已為全球數以千計的香港旅客及國際用戶提供服務。

HelloRoam 亞洲地區數據方案以統一費用涵蓋多個亞洲國家，包括日本、韓國、泰國、新加坡及越南等。一次購買即可於多個目的地使用，毋需為每個國家單獨購買方案。對於行程途經多個亞洲城市的香港旅客，地區方案比單一國家方案更具價格競爭力。在 HelloRoam 選擇地區方案，查看所涵蓋的國家清單及定價。

HelloRoam 方案採用一次性預付費形式，按數據大小及有效期計費，唔使日費、唔使合約、唔使隱藏收費。固定數據方案從 3GB 至 20GB，無限數據方案從 15 天起計。與 CSL、3HK 或 SmarTone 每日收費的漫遊套餐不同，HelloRoam 數據方案費用固定，旅程無論幾多天都只付一次，更易預算外遊開支。 185+ HK$8.07

Google Pixel 電話由 Pixel 3 開始支援 eSIM。你可以在 Pixel 3、4、5、6、7、8 及 9 系列裝置上以低至 HK$8.07 的 HelloRoam 方案進行國際外遊。前往「設定」，選擇「網絡」，進入 SIM 管理員，點選「新增 eSIM」即可安裝方案。方案一經安裝不可轉移至另一裝置，購買前請確認 Pixel 型號是否在支援清單內。

可以。HelloRoam 採用雙 SIM 設計，數位流量卡負責外遊數據，原有香港 SIM 卡繼續接聽來電及接收短訊，包括銀行驗證碼及 WhatsApp 雙重認證。兩個 SIM 同時運作，毋需在兩個號碼之間切換。如香港來電接聽費用高昂，可將原有 SIM 卡切換至僅數據模式，透過 WhatsApp 或 FaceTime 接聽來電，節省更多費用。

HelloRoam 數據用完，可透過 App 或官網隨時購買增量數據，即時生效，數分鐘內恢復上網。毋需刪除或重新安裝設定檔，直接添加至現有方案，操作簡單快捷。旅途中亦可升級至更大容量方案，滿足突發需求。24/7 WhatsApp 客服可協助處理任何補購問題，確保你隨時保持連線。

HelloRoam 5GB 數據方案適合一般一週短途旅行，足夠日常瀏覽、地圖導航及輕度串流使用。根據香港旅客實際使用習慣：每日使用地圖、WhatsApp 及社交媒體約消耗 500MB 至 1GB；每日串流一小時高清影片約再用 1GB。7 天一般使用建議 5GB 至 10GB。如需每日視像通話、大量上傳或熱點共享，建議選擇 HelloRoam 無限數據方案，確保旅途毫無數據壓力。所有方案低至 HK$8.07，按目的地及天數靈活選擇。

HelloRoam 同時提供固定數據方案（3GB 至 20GB）及無限數據方案，適合不同旅行需求。固定數據方案費用較低，適合只需瀏覽網頁、使用地圖及間歇性使用 WhatsApp 的輕度用戶，費用更易預算。無限數據方案適合每日需要視像通話、Netflix 串流、遙距工作或長期旅居的數碼遊牧族及商務旅客。對於前往日本、韓國或歐洲等目的地的香港旅客，行程 7 天或以下建議先試固定數據方案；超過 10 天或有重度使用需求，無限方案每日成本反而更划算。國際 eSIM 流量卡比較時，HelloRoam 兩種方案均唔使合約、唔使隱藏收費。

HelloRoam eSIM covers both Mexico and Canada with local carrier networks. Buy a country plan or a regional Americas plan before crossing the border from Texas, Arizona, California, or any northern state. Share your data via hotspot to a laptop or tablet in your RV. Plans start from HK$8.07 with no daily fees. Your Verizon or T-Mobile number stays active for calls and texts while HelloRoam handles data.

HelloRoam e SIM activates at each port of call, not on the ship itself. Buy a Caribbean regional plan before boarding at Miami, Fort Lauderdale, or Galveston. When your cruise docks in Cozumel, Nassau, or San Juan, your phone connects to a local network for maps, messages, and uploads. Plans start from HK$8.07. Skip the $15/day cruise ship Wi-Fi and use real local data at each stop.

HelloRoam eSIM saves snowbirds money compared to keeping a Verizon or AT&T international plan active for months. A 30-day unlimited plan costs far less than AT&T International Day Pass at $12/day. Buy your e-sim plan before leaving your home state and renew from the HelloRoam app when it expires. No store visit needed in Mexico, the Caribbean, or Central America.

Google Fi charges $10/GB for international data after your base plan runs out. HelloRoam eSIM plans start from HK$8.07 for fixed data with no per-GB overage fees. Google Fi also requires a Google Fi SIM or e SIM as your primary line. HelloRoam runs as a second eSIM alongside your existing AT&T, T-Mobile, or Verizon plan. No contract swap, no number change needed.

T-Mobile Go5G Plus includes free international data but caps speeds at 256kbps in most countries. That is too slow for video calls, maps with live traffic, or streaming. HelloRoam e-sim connects to local 4G LTE and 5G networks at full speed. T-Mobile International Pass costs $5 to $15 per day for faster data. HelloRoam plans start from HK$8.07 as a one-time cost with no daily charges and no speed caps.

HelloRoam eSIM gives digital nomads working from Mexico City, Playa del Carmen, or San Jose full-speed local data for Zoom calls, Slack, and file uploads. Unlimited plans start at $20 for 15 days. Use the hotspot feature to share data with your laptop. Your US phone number stays active through dual SIM so clients can still reach you. Buy a new plan from the app when your current one expires. No Costa Rican or Mexican SIM card needed.

iPhone 15 and iPhone 16 models sold in the US are eSIM-only with no physical SIM tray. Both support dual e SIM, so you can run your AT&T or Verizon line alongside a HelloRoam travel eSIM at the same time. Go to Settings, tap Cellular, then Add eSIM, and scan the QR code from your email. Setup takes under 3 minutes. Works in 185+ countries.

A FaceTime video call uses about 200MB per hour. A Zoom meeting uses roughly 800MB to 1.5GB per hour depending on video quality. A 5GB HelloRoam e-sim plan covers about 3 to 5 hours of daily video calls over a week with regular browsing. For heavy video use, pick a 10GB, 20GB, or unlimited plan. All HelloRoam plans include tethering at no extra charge.

Samsung Galaxy S20 and all newer models support eSIM. Galaxy S24 and S25 series support dual e SIM for running your T-Mobile or Verizon line alongside HelloRoam travel data. Go to Settings, then Connections, then SIM manager, and tap Add eSIM. Scan the QR code from your HelloRoam email. Works in 185+ countries with local 4G LTE and 5G speeds.

A HelloRoam eSIM with hotspot sharing replaces a bulky pocket Wi-Fi device. Turn on Personal Hotspot and connect up to 5 family devices through one phone. No rental fees, no deposit, and no return shipping. A 10GB or 20GB plan handles a family of four using maps, messaging, and social media for a week. Pocket Wi-Fi rentals from US airports cost $10 to $15 per day. HelloRoam e-sim plans start from HK$8.07.

HelloRoam eSIM data works with iMessage, WhatsApp, FaceTime, Telegram, and all messaging apps. Your US phone number stays on your primary SIM for iMessage registration. WhatsApp keeps your number too. A voice call on WhatsApp uses about 30MB per hour. An e SIM data plan handles thousands of messages and hours of voice calls. No separate calling plan needed.

HelloRoam alerts you at 80% data usage so you can plan ahead. If you run out, buy a new plan for the same country from helloroam.com or the app. Scan the new QR code and your phone adds fresh data in under 5 minutes. No need to remove your old e-sim profile. No reinstall, no store visit, no downtime.

Install your HelloRoam e SIM at home or at the airport gate before your flight. The eSIM stays dormant on your phone until you reach your destination. Set it up at JFK, LAX, SFO, ORD, ATL, or any US airport using your existing Wi-Fi or cellular connection. The QR code scan takes under 2 minutes. Your travel eSIM activates the moment your phone connects to a foreign network after landing.

HelloRoam prepaid e-sim plans cost about the same as a local airport SIM card but save you the time and hassle of finding a vendor, dealing with language barriers, and showing your passport. Local SIM kiosks at European and Asian airports often mark up prices by 30% to 50%. HelloRoam plans start from HK$8.07 in USD, and you buy before you leave home.

Most modern iPhones and Samsung Galaxy phones store 8 or more e SIM profiles at once. You can pre-load plans for Japan, Italy, and Mexico before a multi-stop trip and switch between them in Settings. Only one data eSIM is active at a time. HelloRoam also offers regional plans that cover multiple countries under one purchase, so you may not need separate plans at all.

Google Pixel 3 and all newer Pixel models support eSIM. Pixel 7, 8, and 9 series support dual e SIM alongside your existing carrier line. Go to Settings, then Network, then SIM manager, and tap Add eSIM. Scan the HelloRoam QR code from your email. Your phone connects to a local network in 185+ countries the moment you land.

HelloRoam offers short-duration e-sim plans that work for quick border crossings to Canada or Mexico. A 3-day or 7-day plan covers a weekend getaway from cities like San Diego, Detroit, Buffalo, or El Paso. Plans start from HK$8.07 in USD. Skip the T-Mobile or AT&T daily roaming fees and use local data at local speeds instead.

Using your HelloRoam eSIM data is safer than public Wi-Fi at hotels, airports, and cafes. Cellular data runs through encrypted carrier networks. Public Wi-Fi exposes you to packet sniffing and man-in-the-middle attacks. For extra protection, pair your e SIM connection with a VPN app. HelloRoam eSIM profiles meet GSMA SGP.22 security standards.

Your phone must be carrier-unlocked to add a HelloRoam e-sim. AT&T, T-Mobile, and Verizon all unlock phones once they are fully paid off. Check by going to Settings, then Cellular, and looking for an Add eSIM option. If you see it, your phone supports eSIM. If your carrier has not unlocked the device yet, contact them and request an unlock before your trip.

HelloRoam eSIM data works with Uber, Lyft (where available), Google Maps, Apple Maps, and all ride-hailing and navigation apps. Offline maps save some data, but live traffic, ride requests, and turn-by-turn directions need a data connection. A 3GB e SIM plan covers about a week of daily navigation and ride-hailing use. No separate SIM card needed.

An international phone plan from AT&T, T-Mobile, or Verizon adds daily roaming fees to your existing bill. A HelloRoam e-sim is a prepaid data plan you buy once and use until it expires. No daily charges, no bill surprises, no contract changes. You keep your US carrier plan active for calls and texts while HelloRoam handles data abroad. Plans start from HK$8.07 in USD.

Go to Settings, then Cellular on iPhone or SIM manager on Android. Tap your HelloRoam e SIM line and set it as the primary data line. Your AT&T, T-Mobile, or Verizon line stays active for calls and texts. When you return home, switch your data line back to your US carrier in the same menu. The whole swap takes about 10 seconds.

HelloRoam e-sim connects to 5G networks where available in your destination country. Many carriers in Japan, South Korea, UK, Germany, and other popular travel spots offer 5G. Your phone falls back to 4G LTE where 5G is not yet live. Speeds depend on local carrier coverage, not your US plan. Works on any 5G-capable iPhone, Samsung Galaxy, or Google Pixel device.

HelloRoam在三個關鍵方面勝過Airalo：無限日費計劃、24/7 WhatsApp客服，以及支援63種語言。Airalo覆蓋國家較多（逾200個）、固定數據套餐選擇充足。對前往日本、法國或墨西哥的旅客，HelloRoam計劃更靈活，出問題時支援更快。

Airalo在各市場與本地電訊商合作，覆蓋逾200個國家及地區，但各目的地網絡質素不同。Airalo和HelloRoam均連接已建立的本地網絡，遵循GSMA eSIM標準。在日本、英國、法國和墨西哥等熱門目的地，Airalo在市區能提供可靠的4G LTE速度。

HelloRoam是合法的eSIM供應商，在185+個國家及地區擁有逾200個電訊商合作關係。計劃低至HK$8.07，無隱藏費用，無合約。用戶評論確認在日本、法國和英國等熱門美國旅客目的地連線穩定可靠。

HelloRoam對大多數美國旅客而言是更好的選擇。HelloRoam固定計劃低至HK$8.07，覆蓋185+個國家及地區，提供24/7 WhatsApp客服，支援63種語言。Holafly只有無限日費計劃，覆蓋170+個國家及地區，行程超出歐洲或拉丁美洲便受限制。

Holafly的無限數據受公平使用政策約束，並非傳統意義上的真正無限。Holafly在單日重度使用後會降速，具體閾值因國家而異，且通常不會事先清楚說明。HelloRoam無限計劃在購買前會清楚說明任何速度政策，讓你從一開始就清楚知道自己購買的是什麼。

Mint Mobile 透過 Minternational Pass 附加功能提供有限度國際方案，每日收費 5 美元，覆蓋約 40 個國家，且必須持有有效美國方案才可使用。HelloRoam 覆蓋 185+ 個國家，無需美國方案，方案低至 HK$8.07，不設每日附加費。

如果你已以 Google Fi 作為美國主要電訊商且頻繁旅行，Google Fi 在海外使用是合算的。Unlimited Plus 方案無需額外費用即可享用國際數據。但如果你每年只旅行數次，全年支付每月美元65並不划算。HelloRoam 方案低至HK$8.07，只在真正旅行時才付費。

HelloRoam 是按需付費國際數據的最佳選擇：方案低至HK$8.07，覆蓋185+個國家，無月費。Google Fi 將國際方案與本地數據捆綁，每月收費美元20至美元65，只有當你已以 Google Fi 作主要電訊商方案時才合算。

Airalo按固定數據套餐收費，並非統一每GB價格。熱門目的地小容量套餐（1至2GB）起價約美元4.50。較大套餐每次購買金額更高但每GB更便宜。HelloRoam同樣按套餐大小收費，另加無限日費計劃，適合按GB計算費用高昂的旅程。

Samsung Galaxy S20及以上旗艦型號支援eSIM。Galaxy S21至S24、Z Flip和Z Fold系列均有eSIM功能。舊款Samsung和入門級Galaxy A系列可能不支援。前往「設定」，選「連線」，選「SIM卡管理員」確認。HelloRoam和Holafly均適用於任何兼容eSIM的Samsung手機。
