# Block roaming for a specific carrier on the advanced console {% hint style="danger" %} Warning: Blocking a carrier should be done with caution. If the carrier you block is the only available option, the SIM may write it to the FPLMN (Forbidden networks) list. This can prevent the SIM from reconnecting and may require manual intervention to restore service. {% endhint %} 1. Open the Advanced Console for the specific Thing from the Hub.

2. In the Thing details page, select Roaming Policy in the top-right corner.

3. Each profile has its own roaming policy. To block a carrier, you must apply the block per profile.

4. Select Override and locate the carrier you wish to block.

5. In the row for that carrier, check the box under Override (first column on the left).\ Then, in the Block Roaming column (fourth from the left), select the block option.
