Is roaming on Montserrat included for free with a standard UK SIM card plan?

It is a common misconception that due to Montserrat's status as a British Overseas Territory, UK SIM card plans will offer free or low-cost roaming. In reality, most UK and European carriers classify Montserrat as an 'International Zone,' which typically incurs substantial international roaming charges. These fees can quickly accumulate, leading to unexpected and costly bills.
