Cheapest Mobile Operator in Belgium

DIGI offers the cheapest mobile plan in Belgium: €5/month for 30 GB with unlimited calls. hey! telecom follows at €5/month for 15 GB, Yoin at €6/month for 25 GB. Proximus and Orange, meanwhile, raised their prices by €2 to €4/month in January 2026. Here's how to choose the right plan based on your actual usage, without paying for data you'll never use.

A mobile virtual network operator (MVNO) does not own its own antennas: it rents the infrastructure from a major operator (Proximus, Orange or Telenet/BASE) and resells it under its own brand. What you lose: physical stores and integrated customer service. What you gain: a bill often two to four times lighter, on the same network.

Which mobile operator is the cheapest in Belgium?

DIGI is the cheapest operator: €5/month for 30 GB with unlimited calls, or €3/month for 7 GB. hey! telecom offers 15 GB for €5/month, Yoin 25 GB for €6/month.

These prices are stable in 2026: Test-Achats reports that DIGI has committed not to raise its prices this year, while Proximus and Orange raised their plans by €2 to €4/month from 1 January 2026. The gap between a major operator and an MVNO has widened further.

Laura, 34, from Liège, was paying €21/month with Orange for 12 GB. She switched to DIGI in June 2026: €5/month for 30 GB. Saving: €192 per year, with identical coverage in her area.

What do you get for €3/month?

The DIGI plan at €3/month includes 7 GB and unlimited calls. It's enough for light use (messaging, browsing), but not for regular video streaming. 5G is available (DIGI network being rolled out), but coverage remains incomplete outside major cities. No commitment required.

Why are MVNOs cheaper than Proximus or Orange?

An MVNO doesn't build its own antennas: it rents the infrastructure from an MNO (physical network). Less capital costs, less maintenance costs, fewer stores → structurally lower prices.

This is not a question of signal quality: if you're on the Proximus network via Mobile Vikings, you get exactly the same signal as a direct Proximus subscriber. The difference lies in customer service (digital-only for most), the absence of a physical store, and sometimes network priority during peak congestion.

hey! telecom: which network does it use?

hey! telecom runs on the Citymesh network, Belgium's fourth network focused on quality in urban and peri-urban areas. Outside Citymesh zones, hey! relies on roaming. In Brussels, Liège or Ghent, coverage is excellent. In very rural areas, check the map on hey!'s website before subscribing.

Comparison of the cheapest mobile plans in Belgium

The prices below were collected in June 2026 from operator websites and via Selectra and Astel. They do not include temporary promotional offers.

Note: entry-level prices for each operator. For plans with more data or unlimited data, prices increase. Proximus Mobile Smart (60 GB) = €18.99/month; Proximus Unlimited = €34.99/month.

Which mobile plan to choose based on your profile?

There is no single "best plan": it depends on your data consumption, your call habits and the network that works at your location.

You use little data (messaging, browsing, 5–10 GB/month): DIGI at €3 or €5/month, Mega at €7, or Scarlet at €8. These plans cover the essentials for under €10.

You stream or work on the go (15–30 GB/month): hey! at €5/month (15 GB), DIGI at €5/month (30 GB) or Yoin at €6/month (25 GB). Excellent value for data volume.

You need lots of data or reliable 5G: Mobile Vikings (Proximus 4G-5G, 30 GB = €15/month), BASE (Telenet 4G-5G, 15 GB = €12/month) or directly BASE for flexibility and Free Data Day (free data on the 1st of each month).

You travel in Europe: Check EU roaming included. MVNOs like DIGI or hey! include EU roaming in the plan, but sometimes cap the data volume abroad (e.g., 20 GB EU for DIGI). Astel specifies this per operator.

How much do you really save by switching operators?

Switching from a major operator to an MVNO often saves €10 to €20/month in real terms. Over 24 months, that's between €240 and €480.

Concrete example: Orange Mobile Small (12 GB, unlimited calls) is at €15/month after the January 2026 price rise. DIGI 30 GB (same host network in many areas) costs €5/month. Difference: €10/month × 24 months = €240 saved, with twice as much data.

Another comparison: Proximus Unlimited at €34.99/month versus Mobile Vikings Unlimited Basic at €25/month, both on the Proximus network. Difference: €9.99/month × 24 = €240 saved for strictly identical coverage.

Is it complicated to switch mobile operators in Belgium?

No. Via Easy Switch, the IBPT-supervised process, your new plan activates in one business day and you keep your number. You don't have to cancel your old contract yourself: the new operator handles it.

Easy Switch in practice: 3 steps

1. Get your Easy Switch code from your current operator (via the app or by calling 1399).
2. Give this code to the new operator when subscribing.
3. The SIM activates within the agreed timeframe; your old line is automatically cancelled.

If the switch is delayed beyond the agreed deadline, the IBPT provides a €3/day penalty. If you prefer not to wait for a physical SIM, check whether the operator offers an eSIM that can be activated immediately.
