JamboSim eSIM Data Plans for Monaco

JamboSim does not provide a truly unlimited data eSIM for Monaco. The plans that carry the word “Unlimited” give 3 GB of high‑speed data each day; once that amount is reached the connection is throttled to about 1 Mbps.
Customers can instead choose a fixed data plan that offers higher straight‑line data allowances, such as the 10 GB / 30 days plan or the 20 GB / 30 days plan, which allow continuous high‑speed use for the full validity period. These larger‑data plans can be more cost‑effective unless a traveller is an extremely heavy data user.

Yes, JamboSim offers eSIM plans that include a phone number and the ability to send SMS. The plans cover Monaco and are priced from $11.99 USD for 1 GB/7 days up to $105.99 USD for 20 GB/365 days, with validity spans from 7 days to 365 days. The phone numbers use the dialing code +1, meaning they are North American numbers rather than local Monaco numbers. Voice and SMS are available only for outbound use, not inbound. It is advisable to confirm specific call and SMS functions directly with JamboSim before purchase.

JamboSim offers 12 single‑country plans and 18 multi‑country plans in Monaco. The available plans range in price from $1.99 to $101.99 and in data amount from 200 MB up to 20 GB, with validity periods ranging from 3 to 365 days. Some plans provide a fixed data cap while others offer a daily data cap, and additional options such as tethering and a reduced speed clause (up to 1 Gbps) are available for certain selections.
