Airalo's Colombia page, read on 16 September 2026, listed its unlimited eSIM at 92.00 dollars for 30 days against 48.50 dollars for 15 days, about 90 percent more. Because that is under double, two stacked fortnights come to 97.00 dollars, five dollars more than one month. A fixed 50 GB month was 49.00 dollars.
Ninety two dollars. Airalo's Colombia page, read on 16 September 2026, lists its unlimited eSIM at $92.00 USD for 30 days and $48.50 USD for 15 days. The month costs about 90 percent more than the fortnight, which is nearly double and, as the next section shows, just far enough under double to change what you should buy.
Per day the month is the marginally better rate, $3.07 against $3.23, and both sit below every short tier. The three day plan works out at $4.17 a day. That is the shape of almost every travel eSIM ladder, the daily rate falls as the window grows, but it falls slowly and it stops falling at the top.
The EUR render of the same page on the same day showed 43.50 euro for 15 days and 82.00 euro for 30, so the ratio holds in both currencies. Prices on these pages move without notice, so treat the figures as a worked example and redo the division before you pay.
| Validity | Price | Per day |
|---|---|---|
| 3 days | $12.50 | $4.17 |
| 5 days | $19.50 | $3.90 |
| 7 days | $27.50 | $3.93 |
| 10 days | $34.50 | $3.45 |
| 15 days | $48.50 | $3.23 |
| 30 days | $92.00 | $3.07 |
No, not at these prices. Two 15-day plans come to $97.00 and one 30-day plan is $92.00. Stacking fortnights costs $5.00 more and leaves you installing a second eSIM halfway through the trip. In the EUR render the gap is the same size, 87.00 euro against 82.00.
This is worth checking rather than assuming, because the answer turns on one number. Divide the 30-day price by the 15-day price. Today that is 92.00 divided by 48.50, which is 1.90. Under 2 and the month wins. Over 2 and two fortnights win, and on some destinations the 30-day tier really is priced above twice the fortnight.
So the headline that a month costs nearly double is true, and it is also the reason not to split the month. Nearly double is not double. The four steps below are the whole test, and they take about a minute on any provider's country page.
Probably not, and this is where the money is. The same page sells a fixed bucket of 50 GB for 30 days at $49.00 USD, which is $43.00 less than the unlimited month. Twenty gigabytes for 30 days is $39.00 and ten gigabytes is $28.00. The 50 GB bucket is the cheapest data on the page at about $0.98 a gigabyte, against $1.95 at 20 GB and $2.80 at 10 GB.
The fixed buckets also price validity at almost nothing. Five gigabytes costs $15.50 for 15 days and $16.00 for 30. Ten costs $27.00 and $28.00. Twenty costs $38.00 and $39.00. Doubling the window on a fixed bucket costs fifty cents to a dollar. Doubling the window on unlimited costs $43.50. That is the entire finding in two sentences.
The buckets are not hidden, but they are not what you land on either. They sit behind the filter marked Fixed data on the same country page, while the unlimited tiers are the ones most readers see and most round-ups quote. If you only ever compare unlimited windows against each other, the cheapest month on the page never enters the comparison.
| Plan | 15 days | 30 days | Cost of the extra fortnight |
|---|---|---|---|
| 5 GB | $15.50 | $16.00 | $0.50 |
| 10 GB | $27.00 | $28.00 | $1.00 |
| 20 GB | $38.00 | $39.00 | $1.00 |
| 50 GB | not sold | $49.00 | no 15-day tier |
| Unlimited | $48.50 | $92.00 | $43.50 |
Compare the Colombia tiers on AiraloOur partner, and the page these figures came from. The fixed data filter is where the cheap month is, not the unlimited one.Tracked on mobile web only, the page works on desktop too.
Not at full speed. The unlimited plans on that page carry a fair usage note reading Lower speed rate of 1 Mbps after 3 GB usage per day. Five of the six unlimited windows carry it in the package list, the 10-day tier shows no note. The fixed data buckets carry no such note, because a bucket needs no daily throttle, it simply runs out.
Run that through the arithmetic. Three gigabytes a day over 30 days is 90 GB of full speed data for $92.00, which works out at about $1.02 a gigabyte. The 50 GB bucket is $0.98 a gigabyte. To justify the extra $43.00 at the bucket's own rate you would need roughly 44 GB more than 50, so about 94 GB in the month, and the daily ceiling will not let the unlimited plan hand you that at full speed.
That does not make unlimited pointless, it moves what you are paying for. After the daily 3 GB you keep going at 1 Mbps, enough for messaging, maps and a voice call, while an exhausted 50 GB bucket gives you nothing until you buy again. The premium buys a floor under you on a bad day, not volume.
Open the country page, set the currency once, and read every tier in one sitting. Currency matters, because these pages convert and the conversions are not round. The USD render showed $48.50 and $92.00, the EUR render 43.50 euro and 82.00 euro. Comparing a fortnight quoted in one currency against a month quoted in another is how people talk themselves into the wrong tier.
Then check a second provider, because the ladder is not the same everywhere. Nomad's Colombia page, read the same day in its EUR render, sells no unlimited tier for Colombia at all. Its regular plans run 3 GB for 30 days at 8.19 euro, 5 GB at 12.93 euro, 10 GB at 21.55 euro and 20 GB at 33.62 euro, all on Movistar. A provider that does not offer unlimited for a country is telling you something about how much data a month there actually takes.
We date every figure on this site for exactly this reason, and the methodology page explains how. If the tier vocabulary is new, start with how a travel eSIM works, which covers validity windows, daily allowances and what happens when a plan expires while you are still using it.
Set the budget from your own habits, not from the top of the price list. A remote worker with an apartment connection and cafe wifi is on cellular for maps, rides, voice notes and the odd tether. Twenty gigabytes over 30 days is a shade under 700 megabytes a day, which covers that pattern with room to spare, at $39.00.
A traveller with no fixed base, working off the phone and moving between Medellin, Bogota and the coast, is the case for either the 50 GB bucket at $49.00 or the unlimited month at $92.00. The deciding question is not how much data you want. It is whether you can live with 1 Mbps after 3 GB on your heaviest day.
One more thing about long stays. The Colombia ladder stops at 30 days on both providers we read, so six or eight weeks means a second purchase whichever tier you pick. That is another reason to price the month against the fixed bucket rather than against the fortnight, because you will be making the same decision again in a month. The same test works on other destinations, where the tiers land differently. Our Thailand eSIM guide walks the same ladder in another market, and the blog tracks the prices that move.
Airalo's Colombia page, read on 16 September 2026, listed its unlimited eSIM at $92.00 USD for 30 days against $48.50 for 15 days. The same page sold a fixed 50 GB bucket for 30 days at $49.00, and 20 GB for 30 days at $39.00. The EUR render showed 82.00 euro and 43.50 euro for the two unlimited windows.
Per day the month is slightly cheaper, $3.07 against $3.23 on the figures read 16 September 2026. Two 15-day plans come to $97.00 against $92.00 for one month, so stacking fortnights costs $5.00 more and adds a second install. The month only loses that test where a 30-day tier is priced above twice the fortnight.
The unlimited plans carry a fair usage note on the same page reading Lower speed rate of 1 Mbps after 3 GB usage per day. Five of the six unlimited windows carry it, the 10-day tier shows none, and the fixed data buckets carry none. You are buying a 3 GB daily allowance at full speed with a slow floor underneath, not uncapped speed for the whole month.
With an apartment or cafe connection, 20 GB over 30 days is a shade under 700 megabytes a day, which covers maps, rides, calls and light tethering, at $39.00 on the figures read 16 September 2026. Working off the phone all day points at the 50 GB bucket at $49.00 or the unlimited month at $92.00.
Provider pages name the host network and it varies. Nomad's Colombia page, read on 16 September 2026, says it connects you to Movistar and lists 3 GB for 30 days at 8.19 euro. Airalo's Colombia list is split into a data only range and a range that adds SMS and voice minutes. Check the named network against the towns you are going to.
