We don't publish O2's roaming terms: they depend on your plan and change over time. Depending on the plan, international use may be included, offered as an add-on or billed per use. The only reliable source is your O2 online account or app: look for the international or travel section, and note any data included for Barbados and the rate beyond it.
Why add a data eSIM to your O2 line
Plenty of travelers keep their O2 SIM active for calls and texts (bank codes, two-factor authentication) and let a travel eSIM handle data. You know the cost upfront, there's no risk of overage charges, and the phone uses both lines at the same time. If your plan already includes enough data there, an eSIM adds nothing: that's why the check above comes first.
Turning off data roaming on your O2 line
- iPhone: Settings > Cellular > your O2 line > turn off "Data Roaming".
- Android: in the mobile network settings, turn off roaming for the O2 SIM.
- Set the travel eSIM as your cellular data line; on iPhone, also turn off "Allow Cellular Data Switching".
If your O2 plan offers international add-ons, check in your account which ones are active before you leave.
Set up your eSIM in 4 steps
- Make sure your phone is eSIM-compatible and unlocked.
- Buy the plan, then scan the QR code you receive (or install through the provider's app), on Wi-Fi.
- When you arrive, turn on the eSIM line for data, and turn on roaming for that line only.
- Keep your main SIM for calls and texts, with data roaming turned off.
Your phone must be eSIM-compatible and unlocked.

Frequently asked questions
Does my O2 plan work in Barbados?
It depends on your plan. We don't publish O2's roaming terms: check your online account or the O2 app, in the international or travel section, to see how much data is included and what you pay beyond it.
Is O2 roaming or a Barbados eSIM the better deal?
If your plan includes enough data there, roaming is fine. If not, a data eSIM gives you a price you know upfront from $29.00 among the providers we compare. Compare both against how you actually use your phone.
Can I keep my O2 line active with a travel eSIM?
Yes, on a compatible dual-SIM phone. Your O2 line stays available for calls and texts while the eSIM handles data. Just turn off data roaming on the O2 line.
How do I avoid O2 overage charges in Barbados?
Turn off data roaming on your O2 line and set the travel eSIM as your cellular data line. Also check in your account which international add-ons are active.
Will I still get texts from my bank?
Yes, as long as your O2 line stays active. Receiving texts doesn't require data roaming; any cost depends on your plan.
Is my phone eSIM-compatible?
Most iPhones from the XS onward, recent Samsung Galaxy phones and Google Pixels from the Pixel 3 onward are compatible. The phone also has to be unlocked. On iPhone: Settings > General > About, look for the "EID" line.
