Is roaming free in Montserrat if I use my existing UK or European SIM card?

Many travelers mistakenly assume that because Montserrat is a British Overseas Territory, their standard UK or European SIM plan will offer free or affordable roaming. However, this is rarely the case. Most UK and EU carriers classify Montserrat as an 'International Zone,' leading to prohibitively high roaming charges. Opting for a WestESIM provides a cost-effective and transparent solution, ensuring you stay connected with predictable rates without incurring unexpected bills while enjoying your time in Montserrat.
