Why You Shouldn’t Ignore Data Roaming?
Heading overseas? You’ve packed your bags, booked your flights, and planned your itinerary. But have you checked your phone settings? If not, data roaming could quietly rack up hundreds in surprise charges.
Here’s everything you need to know about data roaming, how to manage it, and why using an eSIM can help you avoid those hefty fees.
What Is Data Roaming? How Does It Work?
Data roaming happens when your mobile phone connects to a network outside of your regular carrier’s coverage area. This usually means international networks when you travel abroad. Your local provider partners with foreign networks to keep you connected, but the catch is—you pay for it.
Once you leave your country (or sometimes even a remote domestic zone), your device starts using a third-party network. That’s when data roaming kicks in, and your regular texts, calls, and app activity can rack up extreme charges.
When Does Data Roaming Activate?
Did you know? Just stepping outside your local coverage area—without touching your phone—can start racking up roaming charges. Even if you’re not actively using it, background apps updating or syncing in real time (like email, social media, GPS, or even weather apps) can trigger passive roaming.
Common scenarios include:
International travel: As soon as you land and turn your phone on.
Cruise ships: Mid-ocean towers are expensive and often not covered by plans.
Border zones: Even if you’re still in your country, your phone may connect to a tower across the
Why Data Roaming Can Cost You Big?
Roaming rates are notoriously high. Some carriers charge €10–€20 per MB, meaning a 5-minute Instagram scroll or map load can cost more than your lunch.
Unlike local data plans, roaming often comes with:
▪︎ Limited data caps
▪︎ No warnings when usage spikes
▪︎ Additional fees for tethering/hotspot
Two Main Factors Behind High Roaming Costs
1. Your Location
Your local carrier only covers specific regions. For example, if you’re with a U.S.-based provider like Sprint or Verizon, everything outside the U.S.—say, a quick trip to Mexico—becomes a roaming zone.
Even receiving texts or calls abroad can trigger roaming charges.
2. Your Carrier's Contract
Every provider has different international roaming rates. These can vary from a few dollars per day to hundreds for heavy data users. If you haven’t checked your plan or signed up for a specific roaming package, your charges might look like this:
| Carrier | Data Roaming Rates (Avg) | Roaming Package Cost (Daily) |
|---|---|---|
| Verizon | $2.05 per MB | $10/day TravelPass |
| AT&T | $2.05 per MB | $10/day International Day Pass |
| T-Mobile | $0.25 per minute (voice) | Free text & data (slow speed) |
| Sprint | $2.00 per MB | Global Roaming Add-on |

Yes, if you’re not using an international plan or eSIM.
Is data roaming the same as mobile data?
No. Mobile data uses your local carrier. Roaming is when you use a different network abroad.
Can I still get texts if data roaming is off?
You can receive SMS, but MMS (photos/videos) and iMessages require data or Wi-Fi.
Is it better to use eSIM or roaming?
Using an eSIM is usually better than traditional roaming because it offers local data rates, no hidden fees, and more control. With BNESIM eSIM, you can activate a plan instantly, avoid bill shock, and keep your home number while using local data.
Can data roaming drain battery?
Yes, data roaming can drain your battery faster as your phone constantly searches for and connects to different networks, especially in low-signal areas.
