Bermuda is not part of any domestic roaming agreement for US (AT&T, T-Mobile, Verizon) or UK mobile network operators. Consequently, using your home SIM card in Bermuda will result in high 'Rest of World' international roaming charges. These rates are typically punitive, often exceeding $10-$15 per day for basic data usage, or high per-megabyte fees. CoreESIM offers a dedicated, cost-effective data solution for Bermuda, circumventing these expensive traditional roaming fees and providing a more predictable cost structure.
