Will my existing UK or US SIM card allow free roaming in Poland when using Triply?

When your Triply group travels to Poland, whether your existing SIM allows free roaming depends on its origin. As Poland is an EU member, "Roam Like at Home" applies to EU citizens. However, if you are from the UK post-Brexit, most UK carriers like O2 or Vodafone have reintroduced daily roaming fees. For US travelers, roaming charges are almost always significant. Triply offers a straightforward, cost-effective solution for your entire crew to stay connected without hidden fees.
