I have 2 people in my contacts that I'm unable to text. The SEND button does not respond

Hi Gaylene1949,

So the issue is isolated to two contacts only.

There are a couple sections in this article for troubleshooting contact specific issues.

iOS: Troubleshooting Messages

If you still can't send or receive an iMessage, follow these steps

1. Make sure that the contact trying to message you isn't blocked in Settings > Messages > Blocked.
2. Make sure that the contact you're trying to send a message to is registered with iMessage.
3. If the issue occurs with a specific contact or contacts, back up or forward important messages and delete your current messaging threads with the contact. Create a new message to the contact and try again.
4. If the issue occurs with a specific contact or contacts, delete and recreate the contact in the Contacts app. Create a new message to the newly created contact and try again.

If you still can't send or receive SMS, follow these steps

1. Make sure that the contact who's trying to message you isn't blocked in Settings > Messages > Blocked.
2. Make sure that you're using the area code with the contact's phone number. When sending messages internationally, you also need to use the contact's international code.
3. If you're using a "Pay as you go" SMS plan, make sure it has enough available balance. Contact your carrier if you're unsure of your SMS plan or the available balance.
4. If the issue occurs with a specific contact or contacts, back up or forward important messages and delete your current messaging threads with the contact. Create a new message to the contact and try again.
5. If the issue occurs with a specific contact or contacts, delete and recreate the contact from the Contacts app. Send a new message to the contact.

iImessage on an iPad will not send SMS messages unless you have it tied to an iPhone using continuity.

Do you have an iphone?

Is bluetooth turned on on both devices?

Hi To send Text Messages on iPad you can only send to other ipad/ iPhone users unless iPad has a SIM card. Cheers. Brian
