On 16 September 2026 the same seller priced a three-day unlimited eSIM at $10.50 for Mexico and $19.00 for Canada, 81 percent more. At thirty days it was $62.00 against $86.00, a 39 percent gap. The premium is widest on short plans and nearly vanishes at fifteen days.
Yes, and by more than a pooled comparison table suggests. On 16 September 2026, with the currency selector set to USD, a three-day unlimited plan for Mexico cost $10.50 and the same three days for Canada cost $19.00. That is $8.50 more for the same product, from the same seller, read within a few minutes of each other. In percentage terms Canada cost 81 percent more.
Stretch the trip to a month and the shape changes rather than simply scaling. Thirty days unlimited read $62.00 for Mexico and $86.00 for Canada, a gap of $24.00 or 39 percent. Both prices are much higher, and yet the percentage premium is roughly half what it is at three days, which is the part no single headline number can carry.
The two country pages also sell airtime on different host networks. Mexico plans ran on Movistar, Canada plans on Bell. A reseller pays a wholesale rate to whichever host it uses and cannot sell below what it pays, so the gap starts upstream of the shop. For the mechanics of who you are actually buying megabytes from, how a travel eSIM works sets it out.
Here is the whole unlimited ladder for both countries, read on one day in one currency. The last two columns are the ones the aggregators never print, the dollar gap and the gap as a percentage of the Mexico price.
The curve is not a slope, it is a valley. The premium falls from 81 percent at three days to 5 percent at fifteen, then jumps back up to 39 percent at thirty. A median per-gigabyte figure averaged across that shape says nothing useful about the plan you are about to buy, and on an unlimited plan it has no denominator anyway.
Per day the picture is blunter. Mexico charged $3.50 a day at three days and $2.07 a day at thirty. Canada charged $6.33 a day at three days and $2.87 a day at thirty. Two coincidences are worth noticing. Canada's ten-day rate of $3.50 a day is exactly Mexico's three-day rate, and Canada's very best rate on the page, $2.87 a day for a full month, is what Mexico charged for a fortnight. The same pattern turns up elsewhere in this cluster, including why a Canada month nearly doubles and one price for a three-day eSIM in four countries.
| Plan length | Mexico | Canada | Gap | Canada costs |
|---|---|---|---|---|
| 3 days | $10.50 | $19.00 | $8.50 | 81% more |
| 5 days | $17.50 | $27.00 | $9.50 | 54% more |
| 7 days | $23.50 | $32.00 | $8.50 | 36% more |
| 10 days | $31.50 | $35.00 | $3.50 | 11% more |
| 15 days | $43.00 | $45.00 | $2.00 | 5% more |
| 30 days | $62.00 | $86.00 | $24.00 | 39% more |
Because the two catalogues price the second half of a month completely differently. In Mexico, going from fifteen days to thirty added $19.00 on top of $43.00. In Canada, the identical step added $41.00 on top of $45.00. The second fortnight in Canada cost very nearly as much as the first one, while in Mexico it cost less than half.
That has a practical consequence at the till. Two fifteen-day Canada plans bought back to back come to $90.00 against $86.00 for the single thirty-day plan, so the longer plan saves $4.00. Run the same sum for Mexico and it is $86.00 against $62.00, a saving of $24.00. Buying the longer plan is obvious advice in Mexico and close to a coin toss in Canada, where two shorter plans at least leave you an exit.
It also means fifteen days is the one rung where the country barely matters. If your trip is around two weeks, the $2.00 difference is smaller than the rounding you pick up from a currency conversion, so choose on coverage rather than on price.
No. At the top of the ladder they widen it considerably. Both countries sell metered plans alongside the unlimited ones, and at thirty days the fifty-gigabyte tier is where the difference is at its worst.
The fifty-gigabyte row is the one to stare at. In Canada it cost $84.00 while unlimited cost $86.00, so metering yourself for a month saved $2.00 and bought you a cap you can actually hit. In Mexico the same trade saved $17.00, which is real money. Notice too that a full month of unlimited data in Mexico at $62.00 undercut a metered fifty gigabytes in Canada at $84.00 by $22.00.
At the small end the headline prices look close and the value does not. The cheapest package on the Mexico page was $4.00 for one gigabyte over three days, on the data-only tab. The cheapest on the Canada page was $7.00 for the same gigabyte over the same three days, 75 percent more for identical data. Step up to three gigabytes over three days and the two nearly meet, $7.50 in Mexico against $8.00 in Canada, another rung where the border almost stops mattering.
| Thirty-day plan | Mexico | Canada | Canada costs |
|---|---|---|---|
| 10 GB with calls and texts | $26.00 | $31.00 | 19% more |
| 20 GB data only | $31.00 | $37.00 | 19% more |
| 50 GB data only | $45.00 | $84.00 | 87% more |
| Unlimited | $62.00 | $86.00 | 39% more |
The right move depends almost entirely on how long you are in each country, and the ladder above gives a clean set of rules rather than a vague preference for one side of the border.

Most pages ranking for this question publish a per-gigabyte median pooled across a dozen sellers. Three things go wrong with that. A per-gigabyte price is meaningless on an unlimited plan. Pooling sellers hides the fact that each has its own ladder, kinked in its own places. And a median across plan lengths flattens exactly the valley above, so you are handed one number where the honest answer is six.
You will also see a single tidy percentage quoted for this pairing. On the seller checked here no single percentage survives contact with the catalogue, because the real gap on the day ran from 5 percent at fifteen days to 87 percent on the thirty-day fifty-gigabyte tier. Which number is true depends entirely on which plan you were going to buy.
Prices on these pages move, and the currency selector moves them too. Everything above was read on 16 September 2026 with the selector on USD. The same Mexico page in euros showed 9.50 for three days and 55.00 for thirty, against 17.00 and 76.50 for Canada, so set the selector to your own currency rather than converting by hand. Our methodology explains how we record and date these observations, and the blog runs the same exercise on other pairs, including Colombia, where a month costs double and Kenya, where a week and a month cost the same.
Yes. On 16 September 2026 the same seller priced three days unlimited at $19.00 for Canada and $10.50 for Mexico, and thirty days at $86.00 against $62.00. The premium was 81 percent at three days and 39 percent at thirty. At fifteen days it shrank to $2.00, or 5 percent.
The two country pages sell airtime on different host networks, Movistar for Mexico and Bell for Canada. A reseller pays a wholesale rate to that host and cannot price below it, so the difference starts upstream of the shop you buy from. The seller's own margin then sits on top of both.
Eighty-six dollars on 16 September 2026 for thirty days unlimited on Bell, from the seller checked here. The metered fifty-gigabyte plan for those same thirty days read $84.00, so capping yourself saved $2.00. For comparison, thirty days unlimited in Mexico cost $62.00, which is less than Canada's metered fifty gigabytes.
Price your own itinerary first. The gap between the two countries changes with plan length, so how your days split between the legs decides the answer. Two single-country plans is not automatically the cheaper route, and neither is one regional plan. Compare both totals for your actual dates before you pay.
Yes, on the seller's side and on yours. Every figure here was read on 16 September 2026 with the currency selector set to USD. The same pages in euros showed 9.50 for three days in Mexico and 17.00 for Canada, so set the selector to your own currency before you compare anything against a rival quote.
Thirty days at $86.00 works out to $2.87 a day, the lowest rate on the Canada ladder that day. Fifteen days at $45.00 came to $3.00 a day, and three days at $19.00 came to $6.33 a day. The short plans carry the whole premium, which is why a long weekend stings most.
