how do I fix an issue upon activating iMessage

Hi, how do I fix an issue upon activating iMessage? It’s either “waiting for activation” or “unsuccessful”. I have restarted my phone, turning it on and off but still the same

Had the same issue but I fixed it

1st go to your settings and on the top you’ll see your account tap on that, and you will see name, phone numbers etc tap on that and add the phone number you want to use with iMessage now go back and turn off and back on iMessage it should fix the problem it might take 24 hours, but it works within like 5 minutes also you have to have a little amount of credit on your sim card to activate iMessage

I also faced this issue, but it resolved after a day automatically

Stuck on this from last one week. Tried all solutions available online, but didn’t help.

Make sure your country and region is selected properly. Also, your SIM has ability to send messages. Try sending a normal text to someone.
