Unlimited or Ultra?
Ultra gives you twice the high-speed data allowance of the matching regular Unlimited plan. It does not double the network’s maximum speed. Both tiers remain subject to fair-use policies.

Match the plan to the mainland portion of your trip
The selected fixed-data and regular Unlimited plans use China Mobile 5G and cover mainland China. Their Hong Kong data exit describes internet routing; it does not make them work on a Hong Kong or Macao mobile network. For a Shenzhen–Hong Kong itinerary, compare a regional package from Nomad or the TSimTech offers sold by MobiMatter, or budget for a separate connection.
Install and activate these selections within 180 days of purchase. Plan validity starts on the first supported network connection. Install while you have reliable internet, then enable the line and roaming when ready to use it. Other Roamzo variants can have different activation rules, so keep the actual selected plan details.
What hotspot and Hong Kong routing establish
Roamzo permits hotspot and tethering, subject to device and APN setup. Shared traffic uses the selected plan. Include laptop updates, uploads and companions’ use when sizing a fixed bundle; the ability to share does not create an additional allowance.
The fixed-data and regular Unlimited products returned Hong Kong as their traffic exit in our technical catalog review. This is owned catalog evidence, not an independent app test. Some apps also check the SIM region or account, so there is no universal Google, WhatsApp, TikTok or banking-app guarantee. Hotel Wi-Fi remains a separate connection.
Top up the installed profile before it expires
Fixed-data plans support compatible same-profile top-ups; Unlimited supports matching duration extensions. The current choices and price are checked for the installed eSIM before payment. Fixed top-ups add data and validity. Unlimited extensions add validity on the same tier rather than stacking high-speed allowances.
Unlimited is subject to operator speed management after a high-speed allowance. Data continues during validity, but constant full speed is not promised. Ultra increases that allowance, not maximum network speed. Optional automatic renewal requires saved-card consent and an eligible quote; usage-triggered automatic top-up was not enabled at review.

Check payment and welcome-offer conditions
Card, Apple Pay, Google Pay and local-payment orders need a USD 5 cart total. Smaller orders can add items or use crypto. Automatic renewal also needs at least USD 5 per renewal, so a low-priced base bundle should not be assumed to qualify for recurring billing at that price.
The welcome promotion is a separate gift eSIM with a qualifying first purchase of at least USD 10, not extra data added to every paid bundle. Eligibility and combination limits are checked at checkout. Compare the paid plan on its own merits before counting a gift you may not qualify for.
