Will my existing UK or US SIM incur roaming charges in Estonia, or is Truly Roaming a better option?

When working remotely in Estonia, relying on your home SIM can quickly become costly. If your primary SIM is from the UK, post-Brexit, most carriers such as O2, Vodafone, and Three have reinstated daily roaming fees, often £2-£6 per day. For US-based SIMs, international roaming packages are typically expensive, with data often priced per MB, making video calls or large uploads impractical. Truly Roaming provides a predictable, monthly-stay friendly alternative, ensuring you stay connected for work without unexpected bills.
