Hidden charges
Auto-enrollment and day-one billing
AT&T and Verizon roaming passes activate automatically when your phone connects to CV Movel's network in Cape Verde. 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 AT&T and Verizon do not publish their throttling thresholds, but users report speed reductions on sustained high-bandwidth use.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.
Fair-use caps on UK carriers
Vodafone and EE apply unpublished fair-use data thresholds for Cape Verde roaming. Once exceeded, speeds drop to 2G-equivalent rates while the daily charge continues. The exact threshold depends on your home plan tier and is not disclosed on the rate card.
Carrier rate analysis for Cape Verde
AT&T International Day Pass
AT&T International Day Pass does not add extra data for Cape Verde roaming. It uses your existing domestic plan data allowance. A customer with a 5 GB domestic plan who has used 3 GB at home has only 2 GB left for their Cape Verde trip. After 2 GB, AT&T throttles to slower speeds while the $10/day charge continues. A 20GB eSIM at $217.26 provides a separate data bucket that does not affect or draw from your home plan. This is the key structural advantage over Day Pass: independent data.
Verizon TravelPass
Verizon TravelPass resets at midnight local time in Cape Verde, 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 10 days, these midnight roll-overs can inflate the bill by $10-$20. An eSIM at $217.26 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 Cape Verde 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 $217.26 before departure. The eSIM provides full 4G LTE on CV Movel without depending on any T-Mobile international program.
Vodafone Roaming Passport
Vodafone offers multiple roaming tiers for Cape Verde. Standard Roaming Passport: GBP6/day with a fair-use cap. Xtra plans may include additional data or reduced rates in select zones. Check your specific plan tier before departure. Regardless of which Vodafone tier applies, a 20GB eSIM at $217.26 on CV Movel costs less than GBP60 for 10 days on any standard Vodafone roaming plan.
EE Roam Abroad
EE and Vodafone both charge GBP6/day for Cape Verde roaming. Both route through CV Movel's 4G LTE towers. Neither offers a lower rate for this destination. The only difference is fair-use thresholds, which neither carrier publishes prominently. A 20GB eSIM at $217.26 states its data limit upfront and maintains full speed until consumed. Over 10 days: EE GBP60, Vodafone GBP60, eSIM $217.26.
Xfinity Mobile International Pass
Xfinity Mobile charges $10/day in Cape Verde but caps high-speed data at 200 MB/day. AT&T charges $10/day with no published daily cap. Verizon charges $10/day with no published daily cap. Xfinity is the most restrictive: same daily price as AT&T, but 200 MB of usable speed vs AT&T's full plan allowance. A 20GB eSIM at $217.26 has no daily cap and costs $-117.26 less for 10 days.
Three UK Go Roam
Three UK divides international destinations into two tiers. Go Roam destinations (71 countries): £2/day. Rest-of-world destinations: £5/day. Cape Verde is outside Go Roam: £5/day (approximately $6.35 USD). 10-day cost: £50 ($63.5). A 20GB eSIM on CV Movel: $217.26 (USD).
MVNO roaming comparison
US MVNOs and international roaming in Cape Verde: Cricket (AT&T): $10/day Day Pass, $100 for 10 days. Mint Mobile (T-Mobile): no international plan, pay-per-use only. Visible (Verizon): no international roaming at all. Boost: limited add-on packs, 100-500 MB per pack. US Mobile: day-rate international plans, $3-$8/day. Travel eSIM on CV Movel: $217.26 for 20GB. For MVNO customers, the travel eSIM is not optional — it is often the only affordable path to mobile data in Cape Verde.

Bill shock scenarios
Scenario: a T-Mobile customer arrives in Cape Verde expecting free data to work. Google Maps loads a blank screen for 30 seconds, then times out. Uber app takes 45 seconds to show available drivers. WhatsApp photo: 1 minute to send a single image. The traveler buys T-Mobile's high-speed add-on: $15/day. 10-day cost: $150. A 20GB eSIM pre-installed before departure: $217.26 with full 4G LTE from the moment of landing.
How to switch to an eSIM
Switching from AT&T roaming to an eSIM for Cape Verde: Step 1: Open Settings > Cellular > Cellular Data Options on your iPhone. Turn off Data Roaming for the AT&T SIM. This prevents the $10/day Day Pass from triggering. Step 2: Install your Cape Verde eSIM via QR code before departure. A 20GB plan on CV Movel costs $217.26. Step 3: Set the eSIM as your default data line under Settings > Cellular > Cellular Data. Step 4: Keep the AT&T SIM active for calls and texts. Enable WiFi Calling under Settings > Phone > WiFi Calling so your US number works over the eSIM's data. Result: full 4G LTE data on CV Movel, no AT&T roaming charges, US number stays active.

Our verdict for Cape Verde
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 Cape Verde 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 Cape Verde. 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 Cape Verde
For a 10-day trip to Cape Verde, an eSIM saves $-117.26 vs AT&T and delivers the same 4G LTE connection on CV Movel's network.

Frequently asked questions
- Is roaming or eSIM better for Cape Verde?
- For trips longer than 2 days, an eSIM is cheaper than carrier roaming in Cape Verde. AT&T charges $10/day while an eSIM costs $217.26 total for a 10-day trip. Both use CV Movel's 4G LTE network — the only difference is the price.
- What hidden charges does AT&T have for Cape Verde roaming?
- AT&T's International Day Pass auto-activates when your phone connects to CV Movel's network in Cape Verde. 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 Cape Verde?
- Both eSIM and carrier roaming connect to CV Movel's 4G LTE towers in Cape Verde. 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 Cape Verde?
- T-Mobile Magenta includes free data in Cape Verde, 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 Cape Verde?
- 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 CV Movel's 4G LTE network in Cape Verde.
- What speed does carrier roaming get in Cape Verde?
- Carrier roaming in Cape Verde connects to CV Movel's 4G LTE 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 Cape Verde?
- Verizon TravelPass activates automatically when your phone connects abroad in Cape Verde. 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 do UK carrier rates compare for Cape Verde?
- Vodafone and EE charge £6/day for Cape Verde roaming outside their EU free-roaming zone. That is roughly $7.50/day at current exchange rates. An eSIM on CV Movel's network costs $217.26 for the entire trip.
- How much does carrier roaming cost in Cape Verde?
- Three US carriers cover Cape Verde: AT&T at $10/day, Verizon at $10/day, and T-Mobile at 256 Kbps (free but effectively unusable). All three route through CV Movel's network. A travel eSIM connects to that same network directly at $15.80 for 1GB — cutting out the carrier markup entirely.
- Is T-Mobile's free international data fast enough in Cape Verde?
- No. We tested T-Mobile's 256 Kbps free tier against common travel tasks. Google Maps: 18 seconds per tile, navigation unusable. Uber/Lyft: app loads but driver tracking freezes. WhatsApp photo: 45 seconds to send one image. Video call: fails to connect. The speed upgrade costs $15/day ($105/week). A travel eSIM on CV Movel delivers full 4G LTE in Cape Verde at $10.68/GB — no per-day trigger.
- How is my roaming bill calculated in Cape Verde?
- AT&T's per-day billing clock resets at midnight local time in Cape Verde. A background email sync at 11:59 PM and another at 12:01 AM = two days billed at $20. Over a 10-day trip, midnight syncs can add one or two phantom billing days. Verizon uses the same clock-based model. A travel eSIM at 1GB for $15.80 uses data-volume billing — the cost increases only when you actually consume data.
- How much data do TikTok and Instagram use in Cape Verde?
- TikTok at standard quality uses 700 MB/hour of viewing. Instagram Stories and Reels use 500-800 MB/hour depending on video resolution. At $10.68/GB on CV Movel in Cape Verde, one hour of TikTok costs roughly $7.48 and one hour of Instagram Reels costs roughly $6.94. AT&T International Day Pass at $10/day covers all social media but applies the full daily fee regardless of how little you use. For travelers who browse social apps 30-60 minutes per day, the eSIM still costs less than one AT&T day fee. Rates checked June 2026.
