Hidden charges
Auto-enrollment and day-one billing
AT&T and Verizon roaming passes activate automatically when your phone connects to Claro CO's network in Colombia. Calendar-day billing means arriving at 11:30 PM and leaving before midnight the next day counts as two full day charges. A single background app refresh on landing triggers the first charge.
Speed throttling and data caps
T-Mobile's free international data runs at 256 Kbps — too slow for Google Maps, Instagram, or video calls. Xfinity Mobile caps high-speed data at 200 MB per day before throttling. AT&T and Verizon do not publish their throttling thresholds, but users report speed reductions on sustained high-bandwidth use.
Voicemail and background app charges
Checking voicemail abroad is treated as an inbound international call. If the day pass has not yet activated, that single voicemail retrieval triggers the full daily charge. Background app sync, push notifications, and automatic app updates all count toward data usage and can activate the daily pass without your knowledge.
Carrier rate analysis for Colombia
AT&T International Day Pass
AT&T International Day Pass billing for Colombia: $10 triggers on any calendar day your phone uses Claro CO's network. A calendar day resets at midnight local time, not at midnight EST. A background iCloud sync at 11:59 PM costs $10. A second sync at 12:01 AM costs another $10. Two minutes of background data: $20. Over 8 days, midnight roll-overs can add 1-2 phantom billing days, pushing the actual cost to $100. A 20GB eSIM at $55.50 uses data-bucket billing, which charges based on consumption, not calendar days.
Verizon TravelPass
Verizon TravelPass resets at midnight local time in Colombia, not at midnight in your home time zone. A background email sync at 11:58 PM costs $10 for that calendar day. Another sync at 12:02 AM costs another $10 for the next day. Four minutes of background activity: $20. Over 8 days, these midnight roll-overs can inflate the bill by $10-$20. An eSIM at $55.50 does not bill by calendar day.
T-Mobile International
T-Mobile Prepaid plans do not include Simple Global (the free international data program). Prepaid customers in Colombia get no free data at any speed. International add-ons for Prepaid cost more than postpaid upgrades and cover fewer destinations. T-Mobile Prepaid customers should purchase a 20GB eSIM at $55.50 before departure. The eSIM provides full 5G on Claro CO without depending on any T-Mobile international program.
Vodafone Roaming Passport
Vodafone Roaming Passport for Colombia: GBP6/day. 7 days: GBP42. 8 days: GBP48. This is Vodafone's rest-of-world rate. EU destinations may be included at no extra charge depending on your plan, but Colombia falls under the paid roaming zone. A 20GB eSIM on Claro CO: $55.50 (USD). The eSIM is priced in USD, removing GBP exchange rate uncertainty.
EE Roam Abroad
EE Roam Abroad for Colombia: GBP6/day. 7 days: GBP42. 8 days: GBP48. EU destinations are included on most EE plans post-2021 contract renewals. Colombia carries the rest-of-world zone rate. A 20GB eSIM on Claro CO: $55.50 (USD). The eSIM removes currency conversion uncertainty entirely.
Xfinity Mobile International Pass
Xfinity Mobile runs on Verizon's domestic network but sets its own international rates. The $10/day pass includes only 200 MB of high-speed data per day in Colombia. Verizon's own TravelPass at $10/day provides access to the full domestic plan data. Xfinity customers pay the same daily rate for less data. A 20GB eSIM on Claro CO at $55.50 provides more data than 8 days of Xfinity's 200 MB/day cap would deliver (1600 MB total vs the eSIM's full 20GB).
Three UK Go Roam
Three UK was the first major UK carrier to reintroduce roaming charges after Brexit. Before June 2022, Three customers roamed for free in 71 Go Roam destinations. Post-Brexit, even Go Roam destinations cost £2/day on newer plans. Three UK in Colombia: £5/day (rest-of-world) = £40 for 8 days. A 20GB eSIM: $55.50. The eSIM costs less in both zones.
MVNO roaming comparison
Mint Mobile (T-Mobile MVNO) does not offer international roaming plans. Mint customers traveling to Colombia have no carrier data option. Pay-per-use rates apply through T-Mobile's international billing at rates that can reach $0.20/KB in some markets. A 20GB eSIM at $55.50 on Claro CO is the only practical option for Mint Mobile customers visiting Colombia. No Mint plan tier includes international data coverage.
Rate summary
AT&T (International Day Pass): AT&T International Day Pass costs 44% more than an eSIM for Colombia.
Verizon (TravelPass): Verizon TravelPass costs 44% more than an eSIM for Colombia.
T-Mobile (Magenta (high-speed add-on)): T-Mobile's paid high-speed tier costs more than AT&T and more than an eSIM.
Bill shock scenarios
Scenario: a traveler forgets to add AT&T Day Pass before a 8-day trip to Colombia. Day 1: normal phone use, 200 MB, $410. Day 2: realizes something is wrong after checking the AT&T app, adds Day Pass. Days 2-8: $10/day x 7 = $70. Total: $480 for a trip that would cost $55.50 on a 20GB eSIM from Claro CO. Day 1 pay-per-use alone exceeded the entire eSIM price.
How to switch to an eSIM
Setting up dual-SIM for Colombia (works with any US carrier): Your phone runs two SIMs simultaneously: the home carrier SIM and the travel eSIM. Home SIM role: calls and texts only. Data roaming OFF. WiFi Calling ON. eSIM role: all mobile data on Claro CO's 5G network at $55.50 for 20GB. How they work together: incoming calls arrive on your US number via WiFi Calling routed over the eSIM's data connection. iMessage and WhatsApp stay tied to your home number. Maps, browsers, and apps use the eSIM's data. AT&T/Verizon/T-Mobile cannot bill roaming charges when data roaming is disabled on their SIM.

Our verdict for Colombia
When carrier roaming makes sense
Carrier roaming makes sense for 1-day layovers where the $10 charge is less than the effort of installing an eSIM. Travelers who need voice calling to local Colombia numbers may also prefer their carrier plan, since eSIM data plans do not include voice service.
When an eSIM wins
For any trip longer than 2 days, an eSIM saves money over carrier roaming in Colombia. Families and groups save even more because carrier charges multiply per person. Countries with airport SIM queues make eSIM especially valuable — install before departure, activate on landing.
Bottom line for Colombia
For a 8-day trip to Colombia, an eSIM saves $24.50 vs AT&T and delivers the same 5G connection on Claro CO's network.

Quick tip
Colombia uses COP ($). eSIM plans charge in USD at the time of purchase — you lock in the cost before travel and avoid in-country exchange rate moves.
Good to know
Colombia's emergency number is 123, not 112. Both carrier roaming SIMs and eSIMs can dial emergency numbers without an active data plan.
Frequently asked questions
- Is roaming or eSIM better for Colombia?
- For trips longer than 2 days, an eSIM is cheaper than carrier roaming in Colombia. AT&T charges $10/day while an eSIM costs $55.50 total for a 8-day trip. Both use Claro CO's 5G network — the only difference is the price.
- What hidden charges does AT&T have for Colombia roaming?
- AT&T's International Day Pass auto-activates when your phone connects to Claro CO's network in Colombia. Calendar-day billing means arriving at 11 PM costs a full $10. Background app sync, voicemail retrieval, and notifications can trigger the daily charge on days you intended to stay offline.
- Do eSIMs use the same network as carrier roaming in Colombia?
- Both eSIM and carrier roaming connect to Claro CO's 5G towers in Colombia. The network, coverage area, and download speeds are identical. The difference is pricing: carriers charge $10-$15/day while eSIMs charge a flat rate for the entire trip.
- Is T-Mobile roaming really free in Colombia?
- T-Mobile Magenta includes free data in Colombia, but speed is throttled to 256 Kbps. That is too slow for maps, video calls, or photo uploads. The high-speed add-on costs $15/day — more expensive than most eSIM plans.
- Can I use eSIM and keep my carrier number in Colombia?
- Dual-SIM phones (most models since 2019) run both your carrier SIM and the travel eSIM simultaneously. Your home number stays active for calls and texts over WiFi. The eSIM handles all data on Claro CO's 5G network in Colombia.
- What speed does carrier roaming get in Colombia?
- Carrier roaming in Colombia connects to Claro CO's 5G network — the same towers and speeds that an eSIM uses. AT&T and Verizon offer LTE speeds through their day pass. T-Mobile's free tier is capped at 256 Kbps unless you pay for the high-speed add-on.
- Does Verizon auto-charge for roaming in Colombia?
- Verizon TravelPass activates automatically when your phone connects abroad in Colombia. A single background data transfer triggers the $10/day charge. The only way to avoid it is to disable data roaming in your phone settings before landing.
- How much does carrier roaming cost in Colombia?
- AT&T charges $10/day on International Day Pass for Colombia. Verizon charges $10/day on TravelPass. T-Mobile includes Colombia for free at 256 Kbps — barely fast enough for text messages, not usable for maps or apps. Without any plan, AT&T's pay-per-use rate is $2.05/MB, meaning a single Google Maps session costs over $10. A travel eSIM on Claro CO starts at $4.77 for 1GB — the same 5G network at a fraction of the daily roaming cost.
- Is T-Mobile's free international data fast enough in Colombia?
- No. 256 Kbps sounds like it covers light use, but even a single email with an attachment or a 30-second map route takes over a minute to load at that speed. T-Mobile's free tier in Colombia is functional only for plain text messages. The paid upgrade runs $15/day — identical to AT&T's roaming fee. A travel eSIM on Claro CO at $2.78/GB costs less per GB than any day-pass option and has no speed restriction.
- How is my roaming bill calculated in Colombia?
- A traveler lands in Colombia, checks one notification, and AT&T bills $10 for the entire calendar day. That is how per-day billing works — any cellular connection, even a background sync at midnight, triggers the full daily charge. Without a day pass, AT&T charges $2.05/MB. A 15-second Instagram scroll could cost $30. An eSIM at 1GB for $4.77 is a fixed cost: no per-day triggers, no per-MB metering, no bill surprises.
- How far in advance should I set up my eSIM for Colombia?
- Install your eSIM 1-2 days before departure while connected to WiFi. QR code delivery is instant after purchase. Set the eSIM to activate when you land in Colombia — it connects to Claro CO's 5G network within minutes of arrival. Plan validity starts from first use, not from purchase date, so buying early does not waste paid data. This also gives you time to troubleshoot any installation issues before you are at the airport.
- Can I get a refund on a travel eSIM for Colombia if I don't use it?
- Refund policies vary by provider. Most eSIM providers offer a full refund only if the plan has never been installed or activated. Once the QR code is scanned and the profile downloaded to your device, refunds are rarely issued even if you never traveled. AT&T International Day Pass at $10/day can be cancelled before departure — your account is only billed on days the pass activates in Colombia. For an eSIM on Claro CO at $2.78/GB, read the refund clause before purchase. Plans under $10 total carry no refund window regardless of usage. Rates checked June 2026.
