Belize’s two mobile carriers each sell a tourist SIM for roughly twenty US dollars, and travellers who assume the cheaper-looking one wins are comparing the wrong things. Digi’s Tourist SIM is BZ$40 (US$20) for 25 GB of LTE data, 500 local minutes and texts, and 50 international minutes and texts, valid 10 days. Smart’s Tour SIM “Explore 1” is BZ$45 (US$22.50 at the country’s fixed exchange rate) for unlimited data, BZ$35 of talk time and 130 SMS, also valid 10 days. One is a metered data allowance with generous calling. The other is unmetered data with a smaller calling budget. Neither is objectively better; they solve different trips.
The one number that removes the guesswork: the peg
Belize is one of the easiest countries in the world to price things in, because the Belize dollar has been fixed to the US dollar at exactly BZ$2 = US$1 since 1976. There is no floating rate to check before you travel and no chance the maths in this article is out of date by the time you land: BZ$45 is US$22.50 today, next month and next year, by law. That single fact is worth knowing before you compare any Belize price quoted in BZD against an eSIM reseller quoting in USD.
What Digi’s Tourist SIM actually includes
Digi, the former DigiCell and still Belize’s largest network by its own description, sells its Tourist SIM or eSIM for BZ$40 (US$20), GST included. The package is 25 GB of LTE data plus 500 local minutes and texts and 50 international minutes and texts. Service is valid for 10 days, but the SIM itself stays usable for up to 21 days, which matters if your trip runs long or you want to reload before flying home rather than buying a second SIM. It comes as either a physical uSIM or an eSIM, your choice depending on your device.
Digi does not sell the Tourist SIM at its own retail counters inside Belize City’s international airport terminal. It is sold instead through named agents in seven towns, including one Belize City agent listed on Digi’s own site as based at the airport itself, plus outlets in San Pedro, Placencia, Belmopan, Orange Walk and elsewhere. If you are landing and want one waiting, confirming the specific agent and its hours before you fly is worth the two minutes it takes.
What Smart’s Tour SIM actually includes
Smart, the country’s other carrier, sells two versions. Tour SIM “Explore 1” is BZ$45 (US$22.50) for unlimited data, BZ$35 of talk time and 130 SMS, valid 10 days, with a local Belize number included. There is also a 24-hour “Explore 2” at BZ$20 (US$10) with unlimited data, BZ$11 of talk time and 25 SMS, aimed at a short layover rather than a full trip. Smart states plainly on its own pages that its prices include GST, so the printed figure is the whole figure with nothing added at the till.
- Digi Tourist SIM: US$20, 25 GB metered, 500 local + 50 international minutes, 10-day validity, SIM usable 21 days
- Smart Tour SIM Explore 1: US$22.50, unlimited data, BZ$35 talk time + 130 SMS, 10-day validity, local number included
- Smart Tour SIM Explore 2: US$10, unlimited data, BZ$11 talk time + 25 SMS, 24-hour validity
The eSIM trap Smart’s own FAQ warns about
Smart sells two different products that both happen to be called an eSIM, and only one of them can be set up before you fly. The Tour eSIM is built for remote purchase: you buy it online, a QR code arrives by email, and you activate it once you land. Smart’s ordinary eSIM is a different product entirely, and its own FAQ is explicit about the catch: a visitor must go in person to a Smart showroom to request and activate it. Buy the wrong one by mistake and you have paid for connectivity that requires the exact in-person errand an eSIM is supposed to avoid. There is also a practical limit worth knowing if you visit Belize more than once: Smart automatically deactivates a number after 60 days of inactivity, so a Tour SIM number will not survive between trips taken months apart.
When your plan actually switches on
Activation timing differs by how you bought the SIM, and it is easy to assume a plan is live the moment you land when it is not. Smart states that a plan bought online activates on your first outbound call, while one bought in person through a sales agent activates immediately at the counter. Practically, that means an online-bought Smart eSIM needs you to place one call before data starts counting down, not simply arrive in the country. Digi’s Tourist SIM, bought from an agent in person, activates at the point of sale, so there is no equivalent first-call step to remember.
Buying an international eSIM instead? Check which local network you are actually getting
Airalo’s Belize eSIM runs on Speednet, which is Smart’s network. Holafly’s Belize eSIM runs on DigiCell, which is Digi’s network. That is not a detail either marketplace highlights on its pricing page, but it is the only way to know in advance which of the two Belizean networks you would actually be using, since neither Digi nor Smart publishes a coverage map for the cayes, Cayo or anywhere else. If a friend’s Digi SIM worked fine on Ambergris Caye last year, that tells you something about DigiCell’s coverage there, not about Speednet’s, and vice versa.
On price, the two international brands sit well above either local Tourist SIM. Holafly’s cheapest Belize plan, three days of unlimited data with no local number, runs US$25.50; its 10-day plan is US$68.90, more than three times Smart’s local 10-day Tour SIM at US$22.50, for a product that cannot make or receive local calls. Airalo’s ladder is cheaper but still not competitive with the counter price: 5 GB for 30 days costs US$48, against a 25 GB local SIM for US$20 good for 10 days. The international eSIMs are worth the premium only if you need data live at touchdown and are unwilling to find an agent or a Smart showroom in your first day.
One more device detail worth checking before you buy either carrier’s eSIM: a phone can typically hold multiple eSIM profiles installed at once, but a given QR code can only be redeemed on one device. Install a Digi or Smart eSIM on a phone, then try to move the same code to a second phone or a replacement handset, and it will not activate a second time. If you are travelling with a spare phone or expect to swap devices mid-trip, buy a fresh SIM or eSIM for each device rather than trying to transfer one.
What nobody publishes, and why that matters more here than elsewhere
Belize’s telecoms regulator does not publish a usable coverage map, subscriber-share figures or speed data for either carrier, and neither company’s own site fills that gap with anything more specific than marketing language about being the largest network. That is unusual for a country this dependent on tourism, and it means the advice above is built from what each carrier states about its own product, not from an independent measurement of where either one actually performs best. If a specific caye or jungle lodge matters to your trip, asking your accommodation which carrier the staff use is more reliable than anything published online.
Planning the wider Yucatán route
Belize sits on a common overland and flight route with Mexico’s Yucatán peninsula, and travellers combining the two rarely need to buy connectivity twice if they plan the border crossing around it. If Cancún or the Riviera Maya is part of the same trip, our guide to eSIMs for Mexico covers the operator that changed there this year, and our Cancún guide lays out what else that side of the route costs. Heading south into Guatemala instead, our guide to eSIMs for Guatemala covers data prices from Antigua to Tikal, a route plenty of Belize trips continue onto overland.
What is not worth paying for
Do not buy Holafly’s multi-week unlimited plan for a standard beach-and-cayes trip: at US$158.50 for 30 days it costs more than seven Digi Tourist SIMs bought back to back, and Belize is small enough that reloading once locally is simple. Do not buy Smart’s ordinary eSIM expecting to activate it remotely; that is the Tour eSIM’s job, and the two are not interchangeable despite both carrying the same “eSIM” label. And do not assume the cheaper headline price wins: US$20 for 25 GB and US$22.50 for unlimited data are close enough that the real decision is whether you need a local number and more talk time, or a bigger data cap with international minutes built in.

If the eSIM refuses to activate
Three failures cover nearly every case. The handset is carrier-locked, so the profile installs but never attaches. Data roaming is switched off for the secondary line, which is a separate toggle from the primary on both iOS and Android. Or the profile was installed on airport Wi-Fi with no mobile signal to register against — one flight-mode cycle outside the terminal usually clears that.
Install before you fly, while you still have working data at home, but leave the line switched off until you land. Most providers start the validity clock on first network attachment rather than at purchase, so activating early can quietly cost you a day of a short plan.
Where coverage actually drops
Belize City, San Pedro and the main highways are covered well enough for maps and messaging. The gaps are predictable: the cayes lose signal as soon as you are a few hundred metres offshore, so a boat transfer to Caye Caulker or a snorkel trip to the reef is effectively offline. Inland, the Mountain Pine Ridge and the roads toward the Guatemalan border have long dead stretches. Download offline maps and your booking confirmations before leaving town.
Where to stay
Most trips split between a caye and an inland base. Caye Caulker is the budget end and San Pedro on Ambergris Caye the busier one; San Ignacio is the usual base for the western ruins and caves. Rooms on the cayes book out well ahead over Christmas and Easter.
