If a phone is disconnected, people will generally not be able to send texts to the number associated with that phone. When a phone is disconnected, it means that the service provider has suspended the phone number from their network [1].

Here's what happens when someone tries to send a text to a disconnected phone number:

1. Delivery Failure: In most cases, the text message will fail to deliver. The sender may receive an error message indicating that the message could not be delivered.
2. No Guarantee of Delivery: Even if the text message is sent successfully, there is no guarantee that it will reach the intended recipient. Since the phone is disconnected, the message will not be received on the device.
3. Number Allocation: In some cases, a disconnected phone number may be allocated to someone else. If this happens, any texts sent to the disconnected number may be received by the new owner of the number [3].

It's important to note that different service providers may have slightly different policies and procedures regarding disconnected phone numbers. Therefore, it's always best to contact your specific service provider for accurate information regarding their policies.
