The local option in this country has already gone digital, which changes the usual shape of this page. Digicel Trinidad and Tobago sells a line of My Tourist Plans as eSIMs: pick a plan on its website, register, and the profile arrives by email. The 3-day plan is TT$125, listed as US$20, with 30 GB of data and 100 anywhere minutes. The 14-day plan is TT$250, or US$40, with 42 GB. Both include free calls to Digicel numbers and free local texts, and both work out below a dollar a gigabyte. bmobile, the state-owned TSTT network, sells a physical Prepaid Tourist SIM in three denominations at its stores, including a counter at Piarco.
That leaves the international brands in an awkward spot. The usual argument for them, that you can arrive connected without a counter visit, applies equally to Digicel's own eSIM, and all three international brands run on Digicel anyway. What they still offer is smaller plans with longer validity, a single app for a multi-country trip, and no registration with a Trinidadian operator. Those are real advantages for some travellers. They are not savings.

Digicel's My Tourist Plans, Line by Line
Digicel lists four tourist plans for Trinidad and Tobago, and the first thing to notice is that the data allowances do not rise with the price. The shortest plan carries more data than the week-long one, and the month-long plan carries the least of all. Prices below are as listed on Digicel's tourist page on 14 September 2026, tax included.
| Plan | Price | Data | Anywhere minutes | Cost per GB |
|---|---|---|---|---|
| D' 3 Day My Tourist Plan | TT$125 / US$20 | 30 GB | 100 | About US$0.67 |
| D' 7 Day My Tourist Plan | TT$200 / US$35 | 28 GB | 150 | About US$1.25 |
| D' 14 Day My Tourist Plan | TT$250 / US$40 | 42 GB | 200 | About US$0.95 |
| D' 30 Day My Tourist Plan | TT$365 / US$55 | 25 GB | 300 | About US$2.20 |
Read that table as a menu of durations rather than a ladder. The 14-day plan is the best-balanced product for most holidays, since only five US dollars separate it from the week and it adds 14 GB and another 50 minutes. The 7-day plan is the one to question: for three days' worth of extra validity over the 3-day plan you pay 15 dollars more and receive 2 GB less. If your trip is five or six nights, price the 14-day plan before you default to the week.
The TT$ and US$ figures do not quite agree
Digicel prints both currencies against each plan, and the conversions are not consistent with one another or with the market rate of roughly TT$6.8 to the US dollar. TT$125 is nearer 18 US dollars than 20. If you pay with a foreign card, check which currency the checkout actually charges in, because on some plans paying in TT$ comes out slightly cheaper.
bmobile's Tourist SIM and What It Publishes
bmobile, the mobile arm of the state-owned TSTT, sells a Prepaid Tourist SIM aimed at short-stay visitors. Its own help pages describe the product as coming in three denominations, each pre-loaded with bmobile minutes, texts, anywhere minutes and data, with bundles valid for seven, fifteen or thirty days from activation. The tourist pack is sold at bmobile stores, and bmobile names its store in the Duty Free area at Piarco International Airport as one of them.
What bmobile does not currently publish online is a price list for those three tiers, and third-party guides disagree badly about it. One 2025 guide lists unlimited bmobile tourist data from TT$30 for a day to TT$349 for a month; older summaries describe denominations between TT$50 and TT$200. We would rather tell you that than print a number we cannot confirm. Ask for the current tier sheet at the counter, and compare it against Digicel's published eSIM prices above before you pay.
Buy at a bmobile store with your passport
The tourist pack is sold at bmobile retail stores. Expect to hand over identification, since the SIM is registered to you.
Complete the registration form
bmobile runs an online Tourist SIM registration page that asks for your details with the handset and card in front of you. Do this before trying to use data, not after.
Make a call to activate
bmobile describes activation as first-call activation: the line wakes up once you place a call to any mobile number. Ring your hotel or the store's own number while you are still at the counter.
Note which validity you bought
Seven, fifteen and thirty day bundles all start counting from activation. If your first nights are covered some other way, activate on the day you need it.
The reason to want bmobile at all, given Digicel's online convenience, is network diversity. Every international eSIM sold for this country uses Digicel. A bmobile SIM in the physical slot alongside any of them gives you both national networks in one handset, which is worth more on Carnival days and on the Tobago windward coast than any difference in price.
Local Plans and Travel eSIMs Side by Side
Because every option in this table except bmobile lands on the same Digicel network, this is purely a comparison of money, validity and paperwork.
| Option | Data and validity | Price | Local number |
|---|---|---|---|
| Digicel 3 Day Tourist eSIM | 30 GB, 3 days | US$20 | Yes, with 100 minutes |
| Digicel 14 Day Tourist eSIM | 42 GB, 14 days | US$40 | Yes, with 200 minutes |
| Nomad | 3 GB, 30 days | US$19 | No |
| Nomad | 10 GB, 30 days | US$43 | No |
| Airalo | 1 GB, 3 days | US$8 | No |
| Airalo | 5 GB, 30 days | US$32.50 | No |
| Holafly | Unlimited, 10 days | US$41.90 | No |
| bmobile Tourist SIM | Three tiers, 7 to 30 days | Ask in store | Yes |
The pattern is not subtle. For anything above about 5 GB, the Digicel tourist plans are the cheapest way onto the Digicel network, whether you buy them or an aggregator resells access to them. Holafly's ten unlimited days cost almost exactly what Digicel asks for fourteen days and 42 GB. The international brands only undercut the local operator at the small end, where Nomad's 19 dollars for 3 GB and Airalo's 8 dollars for 1 GB buy less data than Digicel's minimum but cost less in absolute terms.
Where the local plans win
Where travel eSIMs still win
Where to Buy, From Your Sofa to the Savannah
The buying map for this country has three layers, and the first is not a shop at all. Digicel's Tourist eSIM is bought on Digicel Trinidad and Tobago's website: you choose a plan, fill in the registration step, and the eSIM is emailed to you. That can be done a week before travel from home, which removes the airport-counter problem for Digicel entirely.
The second layer is Piarco. bmobile names a store in the airport's Duty Free area as a seller of its tourist pack, and airport guides describe a bmobile kiosk immediately after immigration. Digicel has promoted a kiosk in the duty free zone as well, though its own messaging aims that one at departing passengers. Guides to the airport also warn that hours are inconsistent on late flights and that one or both counters may be shut after about ten at night, so a red-eye arrival should not plan on them.
Buying in Port of Spain or Tobago
Both operators run retail stores in Port of Spain, the larger malls along the East-West Corridor and in San Fernando, and on Tobago in and around Scarborough. Use each operator's online store locator for current addresses and opening hours rather than a printed guidebook list, and avoid the Carnival weekend itself, when many businesses in the capital close or run short hours. Top-up credit for both networks is sold far more widely than new SIMs, in supermarkets, pharmacies and roadside shops.
The third layer is the one most visitors forget: do the purchase before the week you need it. Carnival accommodation, fete tickets and costumes all require a working phone in the days before Carnival Monday, not just on the road, and trying to register a new line in a store queue on the Friday before Carnival is an unforced error.
Running Two Networks for Carnival and Tobago
This country is one of the clearest cases on the site for carrying two lines at once, and the reason is structural rather than about price. Every international eSIM sold here, and Digicel's own tourist eSIM, puts you on Digicel. If Digicel's cells around the Savannah are saturated on Carnival Tuesday, or its signal fails in a particular valley on the Tobago windward coast, nothing else in your phone can fall back to bmobile unless you have deliberately put bmobile there.
Digicel as the data line
Install either Digicel's Tourist eSIM or an international eSIM before you travel and set it as the line for mobile data. This is the line that does the heavy lifting for maps, messaging and uploads.
bmobile in the physical slot
Buy a bmobile Tourist SIM at a store or the Piarco counter if it is open when you land. Keep it as the voice line and as a data fallback you switch to manually when the Digicel line stalls.
Know the manual switch
Practise changing the mobile data line in your settings before Carnival Monday. In the middle of a mas band with a phone in a waterproof pouch is not the moment to find the menu.
If a second SIM feels like overkill, it probably is for a quiet week in Port of Spain or at a Crown Point resort. It stops being overkill for anyone relying on the phone to find their band, their group or their ride home at five in the morning after J'ouvert.
One stop in a longer Caribbean trip?
If Trinidad and Tobago is one leg of an island-hopping itinerary or a cruise, the calculation shifts toward a regional plan that covers several countries under one allowance, because Digicel's tourist plans only work here. Our Caribbean island-hopping eSIM guide sets out when a regional bundle beats buying locally in each port.
Frequently Asked Questions
Can I buy Digicel's tourist plan before I leave home?
Yes. Digicel Trinidad and Tobago sells its My Tourist Plans as eSIMs on its website: you select a plan, complete the registration step and the eSIM is emailed to you. That makes it one of very few local operators in the Caribbean whose tourist product can be arranged before departure. Your handset needs to support eSIM and be unlocked. If it does not, the fallback is a physical SIM from a store in the country.
Why does Digicel's 7-day plan have less data than its 3-day plan?
We do not know, and Digicel does not explain it. As listed in September 2026 the 3-day plan carries 30 GB, the 7-day plan 28 GB, the 14-day plan 42 GB and the 30-day plan 25 GB. The practical consequence is that the 7-day plan is poor value next to the 14-day plan, which costs only five US dollars more and adds 14 GB and extra minutes. Tourist plans get revised, so recheck the allowances at checkout rather than relying on this table months from now.
How much does bmobile's tourist SIM cost?
bmobile confirms that the Prepaid Tourist SIM exists in three denominations with bundles valid for seven, fifteen or thirty days, sold at its stores including the Duty Free area store at Piarco, but it does not publish the prices online. Third-party guides quote figures that contradict each other, so we have not printed one. Ask for the current tier sheet at the counter and set it against Digicel's published eSIM prices before you buy.
Is the local SIM worth it if I am only here for a long weekend?
For three or four days of normal use, Digicel's 3-day Tourist eSIM at US$20 for 30 GB is hard to beat, and because it is bought online it involves no errand. The exception is a very light user who only needs maps and messages between hotel WiFi sessions: Airalo's 1 GB over three days at 8 dollars covers that for less than half the price. A bmobile SIM only makes sense on a short trip if you specifically want the second network.
Will a SIM bought in Trinidad work on Tobago?
Yes, with no roaming and no change of plan. Both operators cover both islands as a single national network, so a Digicel or bmobile line bought in Port of Spain carries straight across on the airbridge or the ferry. Coverage is strongest around Crown Point, Store Bay and Scarborough and thinnest on the windward coast and in the Main Ridge forest, which is exactly where having both networks in one phone pays off.
