Mobile plans in Belgium: SIM-only comparison

SIM-only plans start around €4 to €9 a month for a small data bundle and limited calling, sit between €10 and €15 for a mid-sized bundle with unlimited calls and texts, and reach about €25 for the largest consumer allowances. Handset instalments, where you take one, are billed on top of these figures.
