Inside the EU, you receive an alert if your mobile data roaming exceeds €48 and we will automatically disable your mobile data as soon as your usage reaches €60. To disable this, text “sum ignore” or “sum disable” to +32486191966. What’s the difference between the two? “Ignore” disables the limit for the current month. “Disable” disables the limit indefinitely. To enable the limit again, text “sum enable” to +32486191966.
