Things To Check

What affects your monthly price

Contract length

Rolling monthly plans give flexibility but sometimes cost slightly more per GB than a 12 or 24-month term.

Data rollover

Some packages let unused data carry into the next month; others don't. Worth asking about if your usage varies.

Roaming & hotspot

EU roaming allowances and personal hotspot/tethering limits differ between tiers — check before you travel or work remotely.
