Abroad you have three basic options: eSIM, a pocket Wi-Fi router, or your carrier's roaming pack. The cheapest depends on people, devices and data.
The three options
- eSIM — cheapest for one phone, solo; works on landing
- Pocket Wi-Fi — best to share across devices and people
- Carrier roaming — least hassle, keep your number
How to keep it cheap
Estimate the data you'll use and pick a plan that fits the destination. For multiple countries, a regional plan is usually cheaper.
- Roughly estimate your GB
- Use a multi-country plan for regional trips
- Combine with hotel/venue Wi-Fi
- Turn off call forwarding and auto-renew you don't need
Notes for business travel
- Route work data through a VPN
- Check the plan allows tethering
- Confirm activation and signal right after landing
