11 Shocking Facts About International Roaming Charges
International roaming ranges from completely free (inside the EU/EEA, since 2017) to over $2,000 per gigabyte on a pay-per-use rate outside it. The record bill-shock case still stands at $570,000. Here are 11 facts that explain why and how to avoid becoming the next headline.
1. The Highest Roaming Bill Ever Recorded Was $570,000
An Australian traveller returned from a European holiday to a global roaming bill of $570,000 even after reporting the phone stolen partway through the trip, according to a widely reported Daily Mail investigation.
No publicly reported case since has come close to matching it, though five-figure "horror story" bills are still common in 2026, from cruise-ship data charged at $15–$25 per MB to family streaming bills running past $30,000.
2. Your Phone Can Roam Even While Switched Off
Leave a smartphone off abroad and you're not automatically safe. Devices update automatically the moment they reconnect to a network, and any voicemail left for you is billed at the local roaming rate rather than your home rate.
The safest approach is to prepare your devices properly before you fly by disabling auto-updates and background data, not just powering the phone down.
3. Britons Have Lost an Estimated £573 Million a Year to EU Holiday Roaming
That figure predates two major shifts:
- The EU's abolition of roaming charges in 2017
- Brexit
Since the UK left the EU, free roaming across the EU is no longer guaranteed by law. Most UK networks reintroduced daily EU roaming charges (typically £2–£2.59 per day), with O2 remaining a notable exception for many existing customers.
Always check your provider before travelling.
4. U.S. Businesses Have Paid as Much as $693 in Roaming Fees Per Trip
That widely cited CIO.com benchmark is an older figure, but the underlying problem remains.
Recent 2026 case studies show unmanaged business travellers still facing roaming bills well above $1,000 per trip when no corporate roaming plan is in place.
5. Ofcom Still Doesn't Cap What UK Providers Charge Outside the EU
The UK telecoms regulator does not restrict what networks charge for roaming outside the EU.
However, since October 2024, providers must send roaming-cost alerts after research showed that 19% of holidaymakers were unaware they could face additional charges overseas.
6. Roaming Remains Hugely Profitable for Networks
Roaming revenue continues to be a significant source of profit for mobile operators.
As a result, many providers have been slow to reduce roaming prices unless regulations require them to do so.
7. Around 1 in 7 Travellers Carry an International SIM Card
Research from Telecompaper found that approximately one in seven travellers use an international SIM card while travelling.
Other popular alternatives include:
- eSIMs
- Local SIM cards
- Portable WiFi devices
8. Pay-Per-Use Data Roaming Can Cost Over $2,000 a Gigabyte
Although per-megabyte rates have gradually declined over time, the total cost of roaming can still be enormous.
For example:
- AT&T's published pay-per-use rate of $2.05 per MB equals more than $2,000 per GB.
- A modern smartphone can consume 1GB within minutes through video streaming and automatic app updates.
Most carriers now offer day passes (typically $10–$12) specifically to avoid these expensive default rates.
9. Unmanaged Business Roaming Costs European Companies £2.4 Billion a Year
According to Information Age, unmanaged roaming during business travel costs European companies an estimated £2.4 billion annually.
Much of this expense can be avoided through:
- Managed roaming policies
- International SIM cards issued before travel
10. Europe Actually Did Abolish Roaming Charges — Just Two Years Late
The EU's "Roam Like at Home" programme was originally expected in 2015 before eventually launching on 15 June 2017.
Since then:
- EU/EEA travellers pay no roaming surcharge on calls, texts, or mobile data within participating countries.
- The policy has been extended until 2032.
- Ukraine and Moldova joined on 1 January 2026.
- Montenegro and Albania are expected to join by the end of 2026.
The UK is no longer automatically included following Brexit.
11. Tourists Can't Always Get a Local SIM Card
In several countries, buying a local SIM card remains difficult because of residency requirements, registration rules, or government restrictions.
| Country | Why it's difficult |
|---|---|
| Turkey | SIMs and devices tie to passport and IMEI; tourist SIMs often have time limits (≈120 days) and may need IMEI registration or fees to keep working. |
| Japan | Full-featured local numbers (voice/SMS) are limited for short-term visitors; data-only SIMs and eSIMs are widely available but some vendors restrict voice/SMS provisioning. |
| Cuba | Mobile services are state-run with strict registration and higher costs; purchasing and activating SIMs can be bureaucratic and slow. |
| North Korea | Foreign visitors generally cannot access the local internet or usual mobile networks; connectivity is heavily restricted and controlled. |
| China | Real‑name SIM registration tied to passport is mandatory; eSIMs simplify data-only access but physical SIMs require passport checks and sometimes additional verification. |
| India | Local address verification and paperwork (and various validity rules for tourist SIMs) can delay activation for short-term visitors. |
These rules change frequently and vary by carrier. Always verify the latest requirements before travelling and consider carrying a global eSIM as a backup.
Frequently Asked Questions
Is roaming really free in the EU?
Yes. For most EU/EEA travellers, roaming has been free since 15 June 2017 under the Roam Like at Home policy, now extended through 2032.
UK travellers should check with their provider because Brexit ended the automatic guarantee.
How much does data roaming cost without a plan?
Costs vary by destination and carrier, but pay-per-use rates can exceed $2,000 per gigabyte on some networks. Cruise and maritime roaming can be even more expensive.
Alternatives include:
- Day passes
- eSIMs
- International SIM cards
Can I avoid charges just by keeping my phone off?
Not entirely. Background updates and voicemail can still create roaming charges. Using Airplane Mode or disabling Data Roaming is generally more reliable.
Which countries make it hardest to get a tourist SIM?
Countries with additional restrictions include:
- Turkey
- Cuba
- North Korea
- China
- India
