Quick answer
For most visitors, a good eSIM for Cozumel is Nomad’s 5 GB plan for 30 days at $11: enough data for a week of maps, messaging and some browsing. For a one-day cruise stop, Airalo’s 1 GB for 3 days at $4 is the cheapest verified short plan; Holafly’s 1-day unlimited plan at $4.90 is another option.

Not sure you need one? Do I need an eSIM? compares it with roaming, a local SIM and Wi-Fi. Staying a week or more? Our vacation eSIM guide covers plan length and how much data you need.
Many US plans already include Mexico. Does my phone work in Cozumel? shows how to check yours and the one charge to avoid on a cruise.
On a cruise stop in Cozumel
Cozumel has three cruise piers on the west coast: the International Pier, Punta Langosta and Puerta Maya. Ships usually stay for one day, so a 1-day or 3-day plan is enough. The same Mexico eSIM keeps working if your cruise also stops at Costa Maya or Progreso.
Keep cellular data off while the ship is at sea and switch the eSIM on once you’re ashore. Our Caribbean cruise eSIM guide explains why, and how to cover several islands with one plan. For data at sea, our ship Wi-Fi guides compare each line’s packages with a cruise eSIM: Royal Caribbean, Carnival, Norwegian, MSC and Princess.
Which network will I be on?
Mexico’s main mobile networks are Telcel, AT&T Mexico and Movistar. Airalo (its Mexico plan is called Chido) and Nomad say they use AT&T Mexico and Movistar; Holafly says Movistar and Telcel. Other providers in the table don’t always say which network they use; those rows show “Not stated”.
Is Mexico already in your phone plan?
Cozumel is the one destination on this site where many US travellers don’t need an eSIM at all. AT&T’s eligible unlimited plans and all of Verizon’s Unlimited plans include talk, text and data in Mexico at no extra cost, and T-Mobile’s T-Mix More and Loaded plans (and the older Experience More and Beyond) include 15 GB or 30 GB of high-speed data there. Prepaid and older plans often leave Mexico out, so check your plan in your carrier’s app before you buy.
If your plan doesn’t include Mexico, or you’re on a plan from outside the US, an eSIM from the table above is the cheapest way to get data ashore.
Common questions
Does an eSIM work in Cozumel?
Yes. Travel eSIMs from Airalo, Nomad, Holafly and others connect to local networks in Cozumel (Telcel, AT&T Mexico and Movistar). Your phone must support eSIM and be unlocked.
What’s the cheapest eSIM for Cozumel?
The cheapest verified short plan is Airalo’s 1 GB for 3 days at $4 (checked ). The table above is sorted by price, so the first rows are the cheapest for each trip length.
Is Mexico included in my US phone plan?
Often, yes. Many AT&T, Verizon and T-Mobile plans include calls, texts and data in Mexico. Look for “Mexico & Canada” in your plan details or ask your carrier. Prepaid and older plans often leave Mexico out.
Does one eSIM cover Cozumel, Costa Maya and Progreso?
Yes. All three ports are in Mexico, so one Mexico plan works in each of them. Pick a plan long enough to cover the first port day to the last.
Will a Cozumel eSIM work in Cancún or Playa del Carmen?
Yes. Every plan in the table covers all of Mexico, so it also works in Cancún and in Playa del Carmen across the channel.
