The first question is whether everyone will stay together. A pocket Wi-Fi unit connects nearby devices; the person who takes it to another neighbourhood takes the connection with them. For two people who often split up, two modest data plans can be more useful than one large shared allowance.
| Option | Good fit | Cost or limitation to include |
|---|---|---|
| Existing roaming | Your plan already includes the destination and enough data. | Pass activation, daily triggers, excess data and chargeable calls. |
| One eSIM per person | People travel separately or want no shared battery to manage. | Phone compatibility, each person’s pack and any laptop hotspot cap. |
| Pocket Wi-Fi | The group stays together and several devices need data. | Rental days including collection/return, delivery, deposit, loss fees and shared data limit. |
| Physical local SIM | Your phone lacks eSIM or you need a local calling plan. | Shop hours, registration, SIM-slot availability and activation time. |
Use one calculation for every option
For a hypothetical five-day trip, two HK$70 eSIMs cost HK$140. A HK$25/day router with HK$30 delivery costs HK$155 before any extra billed collection day. A refundable deposit is cash tied up, not an expense if returned in full. These are example quotes: put your actual order totals into the same calculation.
Then compare usable data. Holafly’s China pack, for example, lists 1GB/day for hotspot sharing even though phone data is unlimited. That can rule it out as a whole group’s laptop connection. A router’s large allowance also needs to cover everyone together.
Check these before confirming the order
- For a router, check collection and return hours against your flights, the full late-return and loss charges, and whether a power bank is needed.
- For dual SIM, choose the data line explicitly and review roaming settings on both lines. Apple’s guidance explains separate voice and data selection.
- For a group, agree on a meeting point and save offline directions in case the shared connection fails.
