Hi ​@iaws, 

Thank you for reaching out, and I'm sorry you're having difficulty calling the Dutch landline. I understand why this is confusing when you have inclusive minutes available.

If you're receiving the message "your service does not allow this number", please check the following:

• Make sure the International Calling feature is enabled in the iD Mobile app.
• Check your Bill Cap, as international calls may be chargeable and can be blocked if your Bill Cap is set to £0.
• If necessary, increase your Bill Cap to allow chargeable international calls.
• If you're currently in Belgium, make sure roaming is enabled on both your account and handset.
• If you're calling the Dutch number from the UK, calls to international numbers aren't included in your standard UK allowance and may require available Bill Cap. When roaming in Belgium, calls to eligible Band 1 destinations such as the Netherlands may be included in your roaming allowance, subject to your plan's terms.

If the International Calling feature is active and your Bill Cap allows chargeable usage but the call is still being blocked, please contact us via Live Chat so we can check this further for you.

• International calling is enabled. 
• Bill cap is set to £5 - that should be more than enough for a short call.
• Roaming is enabled on both handset and ID setup. 
• My plan’s terms allow Band 1 calls when in another Band 1 country.

So everything is correctly set up. Why then does it block ?

 Your live chat will have to solve it.
