Quick answer
- Make the phone the hub and share a hotspot to the rest: it is cheapest and simplest to manage.
- Buy a separate plan only when a device must be online away from the phone.
Many travellers carry more than one device. The question is whether each needs its own plan, and usually the answer is no: sharing from one is cheaper and easier to control.
Share, or buy separately
Pros
- Sharing from the phone uses one plan, so it costs less and gives one place to watch usage
- Set up once and every attached device benefits
Cons
- The phone's battery drains much faster while sharing
- A device away from the phone has no connection
Setting it up for a full day
- Set the hotspot with a strong password and switch it off when unused
- Disable syncing and automatic updates on tablets and laptops, which consume data quietly
- Mark the connection as metered on the laptop if the operating system supports it
- Keep the phone on charge during long sharing sessions
Watches with eSIM have different constraints from phones and are often tied to your home operator. Check with the maker and your operator before assuming a travel plan will work on one.
FAQ
Do laptops really use more data than phones?+
Generally yes: desktop sites, system updates and file syncing are all larger. Disable automatic updates before connecting to a hotspot.
Should the tablet have its own plan?+
Only if it will be used away from the phone, such as two people carrying one device each. If they stay together, sharing is enough.
