SimOptions offers eSIM plans for Luxembourg that include a phone number and inbound/outbound voice. Only the Holiday Europe eSIM plan also provides inbound and outbound SMS. That plan costs $38.90 USD, has a 50 GB data cap, and is valid for 31 days. Its phone number uses the dialing code +33, which is a French number, not a local Luxembourg number. Other SimOptions plans for Luxembourg—Travel Basic+, My European eSIM 30 GB, 60 GB, and 120 GB—provide a phone number with inbound/outbound voice but do not support SMS. These plans range from $23.90 USD to $55.90 USD, have data caps from 20 GB to 120 GB, and validity periods from 15 days to 30 days. Users who need specific call or SMS capabilities should confirm the details directly with SimOptions.
