Your carrier's roaming rate in Costa Rica
| Carrier | Plan | Daily Rate | 7-Day Cost |
|---|---|---|---|
| AT&T | International Day Pass | $10/day | $70 |
| Verizon | TravelPass | $10/day | $70 |
| T-Mobile | Magenta (high-speed add-on) | $15/day | $105 |
| Xfinity Mobile | International Pass | $10/day | $70 |
AT&T International Day Pass
AT&T charges $10 for each calendar day your phone uses data in Costa Rica — not each 24-hour window. Arriving after midnight and leaving before midnight the next day costs two full day-pass charges on the same trip.
Verizon TravelPass
Verizon's day pass covers data and calls to the US. Texts to local Costa Rica numbers are billed separately at $0.25-$0.50 per SMS in some plan tiers. Verify before sending local contact messages abroad.
T-Mobile Magenta (high-speed add-on)
T-Mobile does not require you to enable the $15/day Costa Rica pass manually. Your phone connects to Kolbi automatically on landing. The charge appears unless data roaming is switched off before the plane door opens.
Xfinity Mobile International Pass
Xfinity Mobile does not require you to enable the $10/day Costa Rica pass manually. Your phone connects to Kolbi automatically on landing. The charge appears unless data roaming is switched off before the plane door opens.

Real savings scenarios for Costa Rica
Solo traveler
The per-day math for a solo Costa Rica trip: AT&T charges $10 every day your phone touches Kolbi's towers. A 20GB eSIM spread across 10 days works out to $5.10/day. AT&T's daily rate is 2x higher. Over 10 days, that multiplier turns into $49 in real savings.
Family trip
The lowest-cost family option for Costa Rica: buy two 20GB eSIMs at $51 each. Each parent's phone shares data via hotspot with one child's device. Total family data cost: $102 for 10 days. Compare: AT&T for four lines costs $400. The tethering approach saves $298 (75%). Both eSIMs connect to Kolbi at 4G LTE.
Business trip
A 5-day business trip to Costa Rica on AT&T: $10/day x 5 days = $50 on the expense report. A 20GB eSIM on Kolbi: $51. The company saves $0 per employee per trip. Business travelers average 2.5 GB/day (video conferencing, email with attachments, cloud document access). The 20GB plan covers that usage. AT&T charges the same $10/day regardless of consumption.
Long-stay and digital nomads
Roaming cost scales linearly with trip length. eSIM cost does not. 5-day trip to Costa Rica: AT&T $50, eSIM 10GB $31.49. Savings: $18.51. 14-day trip: AT&T $140, eSIM 20GB $53.55. Savings: $86.45. 30-day stay: AT&T $300, eSIM (2 plans) $229.50. Savings: $70.50. The longer you stay in Costa Rica, the wider the cost gap.
Frequent traveler annual savings
A traveler who visits Costa Rica twice per year saves $98 annually by using eSIMs instead of AT&T roaming. Per trip: AT&T $100 vs eSIM $51 for 10 days. Annual AT&T total: $200. Annual eSIM total: $102. Over 5 years: $490 saved.
Extended stay economics
Savings ladder for Costa Rica: 3 days — AT&T $30, eSIM $11.48, savings start on day one. 7 days — AT&T $70, eSIM $26.78. 14 days — AT&T $140, eSIM $53.55, save $86.45. 30 days — AT&T $300, eSIM $153, save $147. The longer the stay, the wider the gap. Per-day carrier billing compounds. eSIM pricing does not.
Frequent flyer savings
A traveler who visits Costa Rica twice a year on AT&T International Day Pass: 2 trips x 10 days x $10/day = $200/year in roaming charges. Two 20GB eSIMs on Kolbi: $102/year. Annual savings: $98. Over five years, that compounds to $490 in avoided roaming fees.
Data usage savings
Social media usage in Costa Rica: Instagram, TikTok, and WhatsApp consume roughly 0.6 GB/hour combined. Two hours of daily social media over 10 days: 12.0 GB. AT&T cost for those 10 days: $100 (flat daily rate). eSIM cost on Kolbi: $30.60 at $2.55/GB. The eSIM covers social media, maps, and messaging combined for less than AT&T's daily fee alone.
Couples trip savings
When a couple splits up during the day in Costa Rica (one at a museum, one at a market), each phone needs its own data connection for maps and messaging. Hotspot sharing fails when partners are apart. Two individual 20GB eSIMs at $51 each: $102 total. AT&T for two lines: $200. Independent eSIMs save $98 while providing separate data for separate activities.
UK carrier comparison
UK carriers lost EU free-roaming after Brexit. Vodafone and EE now charge GBP6/day for rest-of-world destinations including Costa Rica. Some plans still include EU roaming, but Costa Rica may or may not fall under that zone. A 20GB eSIM at $51 applies the same rate regardless of EU classification. UK travelers save $9 vs Vodafone and $9 vs EE for 10 days.
Airport SIM vs eSIM
Costa Rica's Juan Santamaria (SJO) offers prepaid SIMs at $5-10 for 3-10GB / 28 days with a 15-30 minute wait. An eSIM installs before your flight and activates on landing — no queue, no paperwork.
Our verdict
An eSIM saves money in Costa Rica for every trip longer than one day. The single exception: a same-day layover where you need your US number active for voice calls. AT&T's $10 for that one day may be worth the convenience. For any trip of 2+ days, the 20GB eSIM at $51 saves $49 over 10 days on Kolbi's 4G LTE network.

- Can a family share one eSIM in Costa Rica?
- One eSIM stays in one phone, but most eSIM plans allow tethering (personal hotspot). A family of 4 can share a single 10-20GB eSIM through one phone's hotspot instead of paying $10/day per person for carrier roaming.
- Does T-Mobile free data work in Costa Rica?
- T-Mobile Magenta includes free data in Costa Rica, but speed is capped at 256 Kbps. That is too slow for Google Maps, video calls, or uploading photos. The high-speed add-on costs $15/day.
- How much does a 30-day eSIM cost for Costa Rica?
- A 30-day eSIM for Costa Rica depends on data volume. Metered plans (5-20GB) typically range from $8 to $35. Unlimited daily plans run $1-2/day. Both connect to the same local network as carrier roaming at a fraction of the cost.
- How much does carrier roaming cost in Costa Rica?
- If you land in Costa Rica without activating a roaming plan, AT&T bills $2.05 per megabyte. A 10-second Google Maps load at 1.5 MB costs $3.08. Ten minutes of casual app use: $30–$60. AT&T's day pass caps the damage at $10/day. A travel eSIM on Kolbi at $6.99 for 1GB is the only option with a fixed, predictable total cost from day one.
- Is T-Mobile's free international data fast enough in Costa Rica?
- No. To use Costa Rica as a normal traveler — ride-hailing, mapping, messaging with photos — you need at minimum 1 Mbps. T-Mobile's free tier delivers 256 Kbps, which is one-quarter of that floor. The high-speed add-on costs $15/day. A travel eSIM connects to Kolbi's 4G LTE network at $2.55/GB — the same towers, real speeds, no daily charge trigger.
- How is my roaming bill calculated in Costa Rica?
- Carriers bill Costa Rica roaming two ways. AT&T and Verizon use per-day billing at $10/day — the charge triggers even if a background app syncs at 11:59 PM. Without a day pass, AT&T bills $2.05 per MB ($2,099/GB). T-Mobile provides free data at 256 Kbps but charges $15/day for usable speed. An eSIM plan at 1GB for $6.99 is a one-time purchase with no per-day triggers and no usage surprises.
- What is the cheapest way to get data in Costa Rica?
- A travel eSIM at $2.55/GB on Kolbi's 4G LTE network. AT&T roaming costs $10/day. Verizon costs $10/day. T-Mobile's free tier runs at 256 Kbps, which is unusable for navigation or apps. The eSIM beats every carrier option on per-GB cost and provides the same network quality as the paid roaming tiers.
- Can I get a refund on a travel eSIM for Costa Rica 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 Costa Rica. For an eSIM on Kolbi at $2.55/GB, read the refund clause before purchase. Plans under $10 total carry no refund window regardless of usage. Rates checked June 2026.
