Slow data in Cape Verde usually traces back to one of a handful of causes — genuine coverage limitations on quieter islands, network congestion in busy resort areas, or a network selection that isn’t giving you the best available signal.
Quick answer: Try manually switching networks if your current one feels slow, since CVMóvel and Unitel T+ perform differently by island. On quieter islands like Santo Antão or Fogo, slow or intermittent speeds often reflect genuine infrastructure limitations rather than a fixable problem.

Coverage limitations on quieter islands
Cape Verde’s smaller, less-developed islands genuinely have more limited network infrastructure, and slow speeds there often reflect this rather than a problem with your eSIM — the Cape Verde eSIM coverage guide covers this island-by-island pattern.
Network congestion in resort areas
Santa Maria on Sal and other busy resort towns can see temporary slowdowns during peak tourist season, even where underlying coverage is strong — this is usually a temporary congestion issue rather than a genuine signal problem, similar to the pattern covered in the Santa Maria guide.
Trying a different network
CVMóvel and Unitel T+ each perform differently depending on island, and manually switching networks can improve speeds if your current connection feels consistently slow — the manual network selection guide covers how to do this.
Confirming your APN settings
Incorrect APN settings can sometimes cause a connection that technically works but performs poorly — the APN settings guide covers verifying this configuration is correct.
When slow speeds are simply expected
On outer islands like Brava, Maio, or parts of Santo Antão, slower or intermittent speeds are a realistic expectation rather than a fixable problem — the Brava guide covers setting realistic expectations for this specific island.
FAQ
Why is my Cape Verde mobile data slow?
Most commonly genuine coverage limitations on quieter islands, network congestion, or an APN misconfiguration.
Should I try switching networks?
Yes, manually trying the other network can improve speeds if performance varies by provider on your island.
Is congestion in resort areas usually temporary?
Yes, generally resolving outside of peak tourist season.
Does island size genuinely affect data speeds?
Yes, smaller islands have less developed network infrastructure overall.
Could my APN settings be causing slow speeds?
Possibly — worth confirming these match data.esim as expected.
Is slow data expected on outer islands?
Yes, genuinely limited infrastructure on islands like Brava or Maio makes this a realistic expectation.
Final Recommendation
Try manual network selection first, and confirm your APN settings if slow speeds persist outside of obviously remote islands. See the Cape Verde eSIM coverage guide to set realistic expectations by island.
