JamboSim eSIM Data Plans for Romania

JamboSim does not offer a true unlimited data eSIM for Romania. All of its Romania‑specific plans are described as “Unlimited” in name, but each provides a 3GB/day data allowance with a 1000kbps reduced speed after the limit is reached. Fixed‑data plans are available instead, such as the eSIM Romania Unlimited / 30 Days plan that grants 3GB per day for 30 days at $23.99 USD, or the eSIM JamboSim Europe & UK Unlimited / 30 Days plan that delivers the same daily allowance for $25.99 USD. Choosing a fixed‑data plan can be more cost‑effective for travelers who need predictable high‑speed data usage without frequent speed throttling.

JamboSim offers eSIM plans for Romania that contain a phone number and SMS capability. The plans range in price from $11.99 USD for 1 GB over 7 days to $105.99 USD for 20 GB over 365 days. Each plan provides a phone number with the dialing code +1, which is a U.S./Canada number used for outbound calls and sms messages.

Calls can be made outbound only, and SMS can be sent outbound only. No inbound calls or inbound SMS are supported on these plans. Users who need specific call or messaging features should confirm the details directly with JamboSim.

JamboSim provides a total of 12 single‑country data plans that include Romania, while 112 multi‑country plans also cover Romania as part of their broader network. The single‑country and multi‑country offerings are available in a range of data limits from a modest 200 MB to a generous 100 GB, and prices span from about $0.99 USD for the smallest plans up to nearly $197 USD for the largest annual packages. Among the available plans, some are structured with daily data caps—there are 25 of those—while the remaining plans feature a fixed data amount. Tethering is permitted on several of the plans, and a few offer reduced speed options to manage traffic.
