Three questions to ask AT&T
- What's included in Martinique? Data, calls, texts: it depends on your plan, and only your AT&T account or app has the final word.
- What do overages cost? Depending on the plan, extra use is billed per use, blocked, or offered as an add-on.
- Which add-ons are active? Some plans let you add an international pass: check what you already have.
Roaming rules vary by country: EU regulation covers plans from EU carriers, but for most other plans, including US and UK ones, what you pay depends on your contract. We don't publish any AT&T rates: they vary by plan and change over time.
When a data eSIM is the simpler option
If your plan includes nothing, or too little, in Martinique, a travel eSIM gives you a price set in advance, with no overage charges. Your AT&T line stays active for calls and texts; just turn off data roaming on it and set the eSIM as your cellular data line.
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
Where can I find AT&T's rates in Martinique?
In your AT&T online account or app, in the international or travel section. We don't publish them: they depend on your plan and change over time.
Do I need to cancel or change my AT&T plan to travel?
No. A travel eSIM is added next to your AT&T line without touching it: you keep your number and your plan.
How do I turn off data roaming on my AT&T line?
On iPhone: Settings > Cellular > your AT&T line > Data Roaming. On Android: in the mobile network settings, for the SIM in question.
Will my AT&T phone accept an eSIM from another provider?
Yes, if it's eSIM-compatible and unlocked. If you got it through AT&T, check with the carrier that it's no longer locked.
What's the cheapest eSIM for Martinique?
Among the providers we compare, the cheapest plan for a typical trip is from Airalo, at $12.50. Prices are checked on the official websites and dated at the top of the page.
Do I keep my regular phone number?
Yes. Your main SIM can stay active for calls and texts; the travel eSIM only handles data. Remember to turn off data roaming on your main line.
