Our recommendation · North AmericaMexico eSIM sizing: $13.48 for 5 GB over a 7-day trip
HelloRoam is the only one of the five providers here that charges in your own currency, across 31 of them. Mexico's 5 GB plan costs $13.48 and the 20 GB tier costs $37.02, on an operator list naming AT&T and Telcel. Saily beats all four rivals on one column, shipping the only built-in VPN.
For a 7-day Mexico trip, HelloRoam scores highest of the 5 we compare, at 8.7 out of 10 on the published rubric. The 20GB plan for $37.02 handles 11GB of moderate use (maps, social media, browsing) on the 5G network on the ground. HelloRoam pairs a 180-day refund window with support in 63 languages. It refunds an unactivated eSIM for 180 days.
Our recommendation
A 7-day trip to Mexico at 1.5GB/day means 11GB of data. The 20GB plan covers that target at the lowest per-GB cost across all available tiers.
The Pick: 20GB at $37.02
#1 RecommendationThe 20GB plan costs $37.02 in the HelloRoam catalogue and connects to a local network's 5G network. Per-GB rate: $1.85/GB. That is the only per-destination price feed this site holds, so it is the only destination price we quote.
On plan shape and our published rubric, HelloRoam is the best fit of the 5 providers we score for a trip this size. Its own published entry rate is $3.50/GB, and it rates 8.7/10.
Who this plan fits
Travelers staying 7 days who use maps, messaging, and social media. Your daily usage sits around 1.5GB, totaling 11GB for the trip.
Why this plan
Trip-length match
1.5GB per day over 7 days totals 11GB. The 20GB plan adds 9GB of headroom beyond that target. That buffer covers photo uploads, group chats, and the occasional video call.
Per-GB value analysis
Mexico prices in the middle of the catalogue and the top tier is where the value sits. HelloRoam charges $3.49 for 1 GB, $8.59 for 3 GB, $13.48 for 5 GB, $24.59 for 10 GB and $37.02 for 20 GB, which is $3.49, $2.86, $2.70, $2.46 and $1.85 per gigabyte. The 20 GB tier is the only one that breaks $2. A 7-day trip at the moderate 1.5 GB a day benchmark comes to 11 GB, so the 5 GB tier at $1.93 a day covers maps and messaging and the 20 GB tier at $5.29 a day covers everything with room left. Mexico's country record puts local daily use lower, at 1.2 GB. Unlimited for 7 days costs $21.70 at $3.10 a day, which undercuts the 20 GB tier for a week-long stay.
| Tier | Price | Per GB | Best for |
|---|---|---|---|
| 1GB | $3.49 | $3.49/GB | Light use (maps, email) |
| 3GB | $8.59 | $2.86/GB | Light use (maps, email) |
| 5GB | $13.48 | $2.70/GB | Moderate use (social, browsing) |
| 10GB | $24.59 | $2.46/GB | Heavy use (streaming, work) |
| 20GB Pick | $37.02 | $1.85/GB | Heavy use (streaming, work) |
Provider score breakdown
HelloRoam scores 22.3 of 25 across the 5 rubric dimensions for Mexico. 180-day refund window on unactivated eSIMs, tied for the longest. Support in 63 languages, more than the other four combined. The main trade-off: regional multi-country bundles are not available yet.
Operator attachment in Mexico
The attachment list holds two operators for Mexico, AT&T and Telcel, and both carry a 5G label. Two is better than one here for the same reason it is anywhere: a profile that will not register on the first has somewhere else to go. Only 68 of the 185 destinations in this dataset offer that, and 117 do not. The alphabetical order of the list means nothing, and naming either operator as the carrier would be a guess we are not making. The country record adds Movistar MX as a third national carrier absent from the attachment list, and puts 5G in Mexico City and the larger cities with the rest of the country on 4G.
Plan recommendation by usage tier
Each tier maps to a specific plan and provider for Mexico.
Light user
Maps + messagingLight travelers in Mexico (maps, messaging, email) use 4GB over 7 days at 0.5GB/day. HelloRoam's 5GB plan at $13.48 ($2.70/GB) covers the trip, and the 5G network on the ground carries it. That price is from the Mexico catalogue. Mexico's good WiFi means you can offload evening browsing and stay inside the light-use budget. On our tier match, HelloRoam takes Light at 86 out of 100. Its published entry rate is $3.50/GB. The trade-off: no regional bundles yet, so multi-country trips need one plan per country.
Moderate user
Social + browsingModerate-use verdict for Mexico: 11GB over 7 days handles social feeds, navigation and daily browsing on a local network. HelloRoam prices the 20GB tier here at $37.02 ($1.85/GB). Mexico's good WiFi lets moderate users offload evening streaming and stay inside the 11GB budget. Holafly scores highest at this tier, 96 out of 100. Limitation: no per-GB tier, so light users pay for data they will not use.
Heavy user
Streaming + callsHeavy-use verdict for Mexico: 21GB over 7 days at 3GB/day. Unlimited runs $3.37/day on the Mexico catalogue. Commit to 30 days there and the rate drops to $2.76/day, 18% off. Holafly scores 96 out of 100 at this tier. Limitation: no per-GB tier, so light users pay for data they will not use.
Your Mexico trip type, matched to a plan
Weekend, vacation, business, or backpacking. Each trip profile maps to a different plan.
Weekend (2-3 days)
A weekend in Mexico runs 2 days, which is 1 GB at 0.5 GB a day. The catalogue prices the 1 GB tier at $3.49, or $1.75 a day across the trip. The published 3-day unlimited bundle costs $9.30 at $3.10 a day.
Vacation (7-14 days)
A vacation in Mexico runs 7 days, which is 11 GB at 1.5 GB a day. The catalogue prices the 20 GB tier at $37.02, or $5.29 a day across the trip. The published 7-day unlimited bundle costs $21.70 at $3.10 a day.
Business (3-7 days)
A business trip in Mexico runs 7 days, which is 21 GB at 3 GB a day. The 20 GB tier at $37.02 is the largest tier the catalogue sells for Mexico and stops short of that figure. The published 7-day unlimited bundle costs $21.70 at $3.10 a day.
Backpacking (10-30 days)
A backpacking leg in Mexico runs 30 days, which is 15 GB at 0.5 GB a day. The catalogue prices the 20 GB tier at $37.02, or $1.23 a day across the trip. The published 30-day unlimited bundle costs $82.90 at $2.76 a day.
Your Mexico provider comparison
Which eSIM provider fits your Mexico trip? The answer depends on your usage tier, trip length, and priorities. Airalo's case is breadth. Nobody else we score publishes 200 destinations, and nobody else sells a bundle that crosses borders on one eSIM. Against that: $4.50/GB to start, dearer than all four rivals, and 14 days to change your mind. Stop counting gigabytes and Holafly becomes the obvious pick: unlimited days from a published $2.99/day, plus support that is live chat and email in 10 languages, around the clock. The bill for that simplicity is a 1GB daily tethering cap, reduced speed past the fair-use threshold, and no small plan at all if your usage turns out light. Pick Saily if privacy ranks above plan choice. Nord Security's VPN rides on every plan from $3.99/GB published, and the app does not sell your data. Saily publishes 200 destinations, behind only Airalo, and support is email in 1 language, with no round-the-clock hours. Nomad holds the lowest published fixed entry rate of the five at $3.00/GB, which is the genuine win here and the reason light users should price it first. Simple checkout, no account required. Trade-off: a basic app with no real-time data tracking, support that is email in 2 languages, with no round-the-clock hours, no regional bundles, and a refund window that shuts after 30 days. HelloRoam runs 186 destinations on 204+ carrier partners, with a published $3.50/GB on fixed plans. What puts it first on our weighting is cover rather than price: the longest refund window here, tied with Holafly. HelloRoam support is live chat, WhatsApp and email in 63 languages, around the clock. Airalo still publishes 14 more destinations.
Mexico is a peso market billed to you in dollars, so the conversion question is not academic. HelloRoam runs Mexican checkout in 31 currencies. Airalo, Holafly, Nomad and Saily run it in the US dollar and nothing else, and a bank converting into dollars takes 2 to 4 percent on the way through, including on the $37.02 20 GB tier. Support access follows the same pattern: 63 languages at HelloRoam, 12 at Airalo, 10 at Holafly, 2 at Nomad, 1 at Saily. Refund windows read 180 days at HelloRoam and Holafly, 30 at Saily and Nomad, 14 at Airalo. HelloRoam has no multi-country regional bundle among its published shapes, so a Mexico route continuing into Guatemala needs a plan for each.
Why the rubric leader finishes first
HelloRoam finishes first on our published rubric at 8.7 out of 10, and the margin is thin. HelloRoam wins support access outright, live chat, WhatsApp and email in 63 languages, around the clock. It ties the longest refund window at 180 days on an unactivated eSIM. Where it loses: Airalo publishes 200 destinations against 186, and Nomad publishes a cheaper fixed floor at $3.00/GB against $3.50/GB. Mexico itself runs on the 5G network on the ground whoever you buy from.
Alternative options
Different traveler profiles need different plans. Here are runner-ups for each use case.
1GB at $3.49

Common Mexico eSIM questions
Direct answers to the questions travelers ask most about Mexico eSIM plans.
Mexico trip sizing at three published benchmarks
A 7-day trip to Mexico needs 4 GB at the light benchmark of 0.5 GB a day and 11 GB at the moderate benchmark of 1.5 GB a day. The catalogue prices the 5 GB plan at $13.48 and the 20 GB plan at $37.02 for Mexico. Heavy use at 3 GB a day comes to 21 GB, past the 20 GB tier that is the largest sold for Mexico. Those three benchmarks are the same figures the quiz and the data calculator on this site read.
Mexico plan sizing for a moderate traveler
A moderate traveler spending 7 days in Mexico needs 11 GB at 1.5 GB a day. The catalogue prices the 20 GB plan at $37.02 for Mexico, which is $1.85 per GB and $5.29 a day across the trip. That leaves 9 GB of headroom against the 11 GB estimate. The published operator list for Mexico names AT&T or Telcel, and no published source says which one a handset selects.
What unlimited costs in Mexico
The catalogue prices a 7-day unlimited bundle for Mexico at $21.70, which is $3.10 a day. The fixed 20 GB tier costs $37.02 and covers the 11 GB a 7-day trip needs at the moderate benchmark. The unlimited bundle is the cheaper of the two here by $15.32. Unlimited bundles carry a fair-use policy rather than an open tap.
Published entry rates across the five providers
HelloRoam publishes a $3.50/GB fixed entry rate and takes checkout in 31 currencies, against 1 currency apiece at Airalo, Holafly, Nomad and Saily. Published fixed floors across the scored 5 read $3.00/GB at Nomad, $3.50/GB at HelloRoam, $3.99/GB at Saily, $4.50/GB at Airalo, with Holafly selling by the day at $2.99/day. The cheapest Mexico plan in that catalogue is 1 GB at $3.49, a destination price rather than a published floor. Support runs in 63 languages there, against 12 at Airalo, 10 at Holafly, 2 at Nomad and 1 at Saily.
A travel eSIM beside a Mexico local SIM
The catalogue prices a 1 GB eSIM for Mexico at $3.49, installed before departure over home WiFi. The country record puts an airport SIM at $10-25 for 5-15GB / 15-30 days, with a counter wait of 10-15 min. Mexico publishes no SIM registration requirement in the country record. HelloRoam refunds an unactivated eSIM for 180 days, against 30 days at Saily and Nomad and 14 at Airalo.
Setting up a Mexico eSIM in four steps
Buy the tier that matches the trip: the Mexico ladder starts at $3.49 for 1 GB. Install the profile over home WiFi under Settings, Cellular, Add eSIM on iPhone, or Settings, Network, SIMs, Add eSIM on Android. Turn on data roaming for the travel line and leave the home line's data off. On arrival the profile attaches to a local network.
Your questions, answered
What is the best eSIM plan for Mexico in 2026?
The 20GB plan at $37.02 on a local network, a HelloRoam catalogue price. It covers 7 days of moderate use at $1.85/GB. 7 plans are available across 5 providers.
How do I choose between fixed and unlimited data for Mexico?
Fixed data wins for trips under 11 days at moderate use. Unlimited at $3.37/day saves money if you use more than 3GB per day or stay longer than 11 days.
Which eSIM provider is best for Mexico?
HelloRoam scores 22.3 of 25 for Mexico across per-GB value, plan flexibility, buyer protection, support access, and destination reach, which is first of the five on this site's weighting. 180-day refund window on unactivated eSIMs, tied for the longest. Regional multi-country bundles are not available yet.
Can I switch plans mid-trip in Mexico?
Yes. Buy a second eSIM through the provider app while in Mexico. Most phones support 8+ eSIM profiles. Delete the expired plan to free a slot. You do not lose your home number.
How far in advance should I buy my Mexico eSIM?
Buy 1 to 3 days before departure. Install the QR code over WiFi at home. The validity timer starts at first network connection in Mexico, not at purchase. This gives you time to troubleshoot any installation issues before your flight.
Is the 20GB plan enough for streaming in Mexico?
Streaming puts a traveler on the published 3 GB heavy band. Over 7 days that is 21GB. The 20GB plan falls short for daily streaming. Heavy streamers should consider 20GB or unlimited at $3.37/day.
What network does my Mexico eSIM connect to?
2 operators carry Mexico on the published list, and your eSIM attaches to AT&T or Telcel. The published list carries the 5G capability label, and it does not record which operator a given handset selects. Save offline maps for Mexico before you fly.
