JamboSim eSIM Data Plans for Spain

JamboSim’s plans for Spain that carry the “Unlimited” name actually provide a fixed data allowance of 3 GB per day. After the daily 3 GB limit is reached, the connection is throttled to a reduced speed of 1000 kbps, so the offer is not truly unlimited high‑speed data.

Travelers who need more data can choose one of the fixed‑data plans that are available. For instance, a 20 GB plan valid for 30 days costs $8.99 USD and gives access to 5G, while a 50 GB plan valid for 30 days is priced at $75.99 USD. These options provide larger overall data allowances and can be more cost‑effective for users who require high‑speed data throughout their stay in Spain.

JamboSim does not provide an eSIM with a local phone number or SMS capability for travelers in Spain. The company offers only data‑only plans that let you connect to the internet via 4G or 5G services. For voice and messaging you can rely on Internet‑based applications such as WhatsApp, Telegram, or iMessage, which work over the data connection without needing a traditional phone number.

JamboSim offers 12 single‑country plans that cover Spain and 47 multi‑country plans that include Spain in their coverage. The single‑country plans range in price from $1.99 to $185.99, with data caps from 200 MB up to 100 GB and validity periods between 3 and 365 days. The multi‑country plans have a similar price span ($1.99‑$185.99), but the data caps vary from 200 MB to 100 GB and the validity can extend up to a full year. The single‑country options are primarily fixed data plans, whereas the multi‑country lineup includes both fixed data caps and daily data cap plans, allowing travelers to choose between a set amount of data for the entire validity period or a daily allocation.
