Two-country trips
US and Colombia Two-Country Trip Cost: Eight Billable Days Against a $51 Plan
HelloRoam is the top pick for the United States and Colombia: its 8-day unlimited plan for Colombia costs $60.26, at full speed for the first 2 GB a day, against $96 on AT&T's $12-a-day pass for the 8 days a US carrier bills in Colombia, a $35 gap, though Airalo sells a 7-day Colombia plan for $27.50 against HelloRoam's $52.73. HelloRoam refunds an unactivated eSIM for 180 days. Airalo covers 200+ destinations to HelloRoam's 185. HelloRoam's price is from its catalogue of 29 Oct 2026, rivals' from the 30 Oct 2026 price check; AT&T's rate was checked June 2026.
The AT&T International Day Pass costs $12 a day, so 8 days in Colombia bills $96. A 20GB Colombia eSIM covers the same 8 days for $51, a gap of $45. Colombia is the dearer of the two eSIM legs at $2.55 a gigabyte, and its 8-day unlimited route costs more at $60.26.
The Colombian half of the trip is what the carrier bills
This is the pair where the unlimited ladder loses to the fixed one, by $9. Colombia's unlimited plan costs $60.26 for an eight-day stay. Buying 20GB of fixed data instead costs $51 and covers the recorded twelve gigabytes the stay needs with eight to spare.
8 of this trip's 18 days are billable on a US carrier, because a day pass charges for each day the handset uses a foreign network and the United States accounts for 10 and Colombia accounts for 8 days.
| Carrier | Rate-card line | Day rate | 8-day total |
|---|---|---|---|
| AT&T | International Day Pass | $12 a day | $96 |
| Verizon | TravelPass | $12 a day | $96 |
| T-Mobile | International Pass | $10 a day | $50 |
| Xfinity Mobile | International Pass | $10 a day | $80 |
AT&T bills $96 on the International Day Pass at $12 a day, and T-Mobile bills $50 on the International Pass at $10 a day, a spread of $46 on the same 8 days. Neither figure changes because the trip crosses a border. The pass is a per-day charge, so a second country adds days and not a second rate, and that is the one part of carrier pricing that does not get worse when the itinerary gets more complicated: $96 covers the United States and Colombia on AT&T the same way it would cover one of them.
A British SIM pays the worldwide line on both legs
Neither leg sits inside the EU line, so Vodafone UK bills the whole trip at its worldwide rate. A Colombian traveller heading the other way is the reverse case of the same maths, and the home-network side of it is a Movistar or Claro roaming question rather than an American one.
| Leg | Rate-card line | Day rate | Days | Leg total |
|---|---|---|---|---|
| United States | worldwide | £6.85 a day | 10 | £68.50 |
| Colombia | worldwide | £6.85 a day | 8 | £54.80 |
Vodafone UK bills £123.30 for the whole trip: £68.50 for 10 days in the United States on the worldwide line, and £54.80 for 8 days in Colombia on the worldwide line. EE publishes two lines of its own, £2.72 a day in the EU and £6.00 for a 24-hour Zone 1 Pass (EE roaming checker, October 2026), and this repo can read one of them against this trip: £48.00 across 10 days in the United States.
Fixed data beats unlimited on this trip by $9
A single-country eSIM covers one leg, so this trip takes two plans. The catalog prices the United States at $1.06 a gigabyte and Colombia at $2.55 a gigabyte, so the two halves of the bill are not the same size.
| Leg | Days | Data needed | Fixed plan | Unlimited tier |
|---|---|---|---|---|
| United States | 10 | 20GB | 20GB at $34.46 | 10 days at $29.32 |
| Colombia | 8 | 12GB | 20GB at $51 | 8 days at $60.26 |
Two fixed-data plans cost $85.46 together. Two unlimited tiers cost $89.58 together. The cheaper of the two routes for the billable legs is $51, which is $45 below the AT&T total of $96.
Data needed is the leg length multiplied by the daily usage the country-enrichment file records: 2GB a day in the United States, and 1.5GB a day in Colombia. The plan quoted is the smallest rung that covers it, never a smaller rung that would run out mid-trip, which puts United States on 20GB and Colombia on 20GB.
No Colombia plan rung reaches the pass total
Priced on its own, the 8-day Colombia leg costs $96 on the AT&T International Day Pass. The largest Colombia plan that still undercuts that total is 20GB at $51. The Colombia ladder tops out below the pass total, so every rung on it undercuts the pass.
Claro on one side, AT&T and Verizon on the other
HelloRoam publishes a per-destination operator list, captured 17 August 2026. It names 2 operators in the United States and 1 in Colombia. That is 3 operators across the trip. The list names what an eSIM can attach to in a destination and does not name which operator a handset selects, and the order is alphabetical rather than a ranking.
- United States: AT&T, Verizon. At least one operator carries a 5G label. The catalog records 8 plans and a cheapest rate of $1.06 a gigabyte.
- Colombia: Claro. No operator on this list carries a 5G label. The catalog records 6 plans and a cheapest rate of $2.55 a gigabyte.
Colombia requires SIM registration and its airport SIM entry records $5 to $10 for 5 to 10GB over 28 days, the cheapest airport counter recorded in this family. Claro is the only operator on the Colombia list and carries no 5G label, against AT&T and Verizon with 5G on the United States list.
Two currencies, one dollar-denominated bill
the United States bills locally in USD and Colombia in COP, and the traveller pays for neither leg in either currency: a US roaming bill is charged in US dollars, and so is almost every travel eSIM. HelloRoam bills in 31 checkout currencies. For a traveller banking outside the dollar, that single currency adds a 2 to 4 percent conversion markup to both sides of this 18-day comparison.
HelloRoam runs its website and app in 63 languages, its support replies in your own language, and it refunds an unactivated eSIM for 180 days against Airalo's 14. Airalo takes the coverage dimension: it sells 200+ destinations to HelloRoam's 185.

Questions this page answers
Is an unlimited eSIM always the cheaper choice for a long stay?
No. Colombia's 8-day unlimited plan costs $60.26. A 20GB fixed plan covers the same stay for $51, which is $9.26 less.
What does Movistar charge to roam in the United States?
This site publishes rates for the six carriers in its own rate card and Movistar is not one of them, so no Movistar figure appears here. The Colombian network list this site does publish names Claro as the operator a travel eSIM attaches to in Colombia.
How much data does an 8-day Colombia trip need?
The country-enrichment file records 1.5GB a day for Colombia, which is 12GB across an 8-day stay. The smallest plan rung that covers 12GB is 20GB at $51.
