How to Avoid Roaming Charges: A Practical Checklist for Travelers
A 10-step checklist to keep your phone bill predictable abroad — from carrier checks before you leave to the settings that quietly use data while you travel.
Quick answer
- Check your carrier's roaming terms for your destination before you travel.
- Turn off data roaming on any line you don't want to roam on, and disable automatic data switching.
- Reduce background data, use Wi-Fi for heavy tasks, and consider a separate travel data plan.
- Watch out for borders, cruise ships and planes — and for calls and voicemail, which roam separately.
How to avoid roaming charges: the short answer
Know your carrier's price before you go, set your phone up before you land, and keep background data in check while you travel. Most surprise bills come from pay-per-use roaming combined with apps that use data quietly.
How roaming is priced is explained in data roaming charges. This checklist turns that into action.
The 10-step checklist
Before you leave
- Look up your destination on your carrier's roaming page or app. Note whether roaming is included, the daily fee or bundle price, and any caps.
- Turn on usage alerts and spending caps if your carrier offers them.
- Decide how you'll get data — roaming, a travel eSIM, a local SIM, or Wi-Fi only.
- Download offline content — maps, playlists, shows, tickets and boarding passes.
- Update apps and software on home Wi-Fi.
On your phone
- Set Data Roaming correctly — off on your home line if roaming isn't included; on for a travel eSIM line if required. Steps: turn off data roaming.
- Turn off automatic data switching between SIMs, and Wi-Fi Assist or adaptive connectivity features that fall back to mobile data.
- Reduce background data — enable Low Data Mode or Data Saver, pause photo backups and turn off video autoplay.
While you travel
- Use Wi-Fi for heavy tasks like video calls, uploads and large downloads — see data roaming vs Wi-Fi.
- Check your usage daily, especially if you're on pay-per-use or near a cap.
Settings that quietly use roaming data
| Setting | Why it matters | What to do |
|---|---|---|
| Photo and video backup | Uploads can be very large | Set to Wi-Fi only |
| App updates | Downloads can be hundreds of MB | Wi-Fi only, or update before you go |
| Video autoplay | Streams video as you scroll | Turn off in each app |
| Wi-Fi Assist / Adaptive connectivity | Switches to mobile data when Wi-Fi is weak | Turn off while roaming |
| Automatic data switching | Can use your home line for data | Turn off on dual-SIM phones |
Not sure which switch does what? Data roaming vs mobile data explains the difference.
Watch out for
- Border areas — your phone may connect to a neighbouring country's network.
- Ferries, cruise ships and flights — maritime and in-flight networks are usually billed separately. Use airplane mode with Wi-Fi.
- Voicemail and incoming calls — some carriers charge for these while roaming.
- Hotspot — sharing data with a laptop uses it fast.

How much data will you actually use?
A rough guide: messaging uses very little, maps use a few to tens of MB per hour, and video can use 0.5–1 GB per hour or more. Estimate your trip with mobile data abroad, then compare that figure with your carrier's pricing.
Is a travel eSIM a good way to avoid roaming charges?
It can be. A prepaid travel eSIM gives you a set amount of data for a fixed price, and you can keep your home line's data roaming off. But if your plan already includes roaming in your destination, you may not need one. Compare both in data roaming vs eSIM, and see what to look for in choosing a travel eSIM.
The bottom line
Roaming charges are avoidable with a few minutes of preparation: check your carrier's terms, set your switches deliberately, stop background data, and keep an eye on usage. Then pick the cheapest way to stay connected — your plan, Wi-Fi or a travel eSIM for your destination.

Frequently asked questions
How can I avoid international roaming charges?
Check your carrier's roaming terms before you travel, turn off data roaming on lines you don't want to roam on, use Wi-Fi for heavy use, reduce background data, and consider a travel eSIM or local SIM.
Does airplane mode stop roaming charges?
Yes. Airplane mode blocks all cellular activity, including calls, texts and data. You can turn Wi-Fi back on while airplane mode stays on.
Can I be charged for incoming calls abroad?
With some carriers, yes — including calls that go to voicemail. Check your carrier's roaming terms.
Why was I charged for roaming with data roaming off?
Common reasons are calls and texts, data used before you switched it off, automatic data switching to your home line, or maritime and in-flight networks billed separately.
Do spending caps stop roaming charges completely?
They limit roaming data once you hit the cap, but they may not cover calls and texts, and usage records can arrive late. Check what your carrier's cap includes.
