Costa Rica eSIM vs UK roaming: real cost in £
Answer: Save up to 90% vs UK roaming. Most travellers spend £4–£15 on a TripSIM Costa Rica plan instead of £40–£250 on UK roaming for the same trip. The reason is simple — UK carriers charge £8–£12 per MB once you leave EU roaming zones, and Costa Rica is outside most UK "roam-like-at-home" bundles. A 5 GB TripSIM Costa Rica plan replaces what would otherwise be £8–£12 per MB × thousands of MB.
- Quick check-in trip (3 days, ~3 GB): TripSIM ~£4–£8 vs UK roaming ~£60+
- Standard holiday (7 days, ~10 GB): TripSIM ~£8–£15 vs UK roaming ~£150+
- Long trip / digital nomad (14+ days, unlimited): TripSIM single fixed price vs uncapped roaming charges
- Heavy maps + video calls user: still capped at the TripSIM plan price — no bill shock

Phones bought outright from Apple, Google or the Samsung UK store are unlocked by default. Contract handsets from EE, Vodafone, Three or O2 are unlocked automatically as well.
