iphone IOS 15.1 still cant send a text to android phones.

As I’ve never seen a post from you before, I have no idea what troubleshooting you have done. Here’s some things to check:

• Can you send basic texts with no pictures? - If not, contact Verizon; basic SMS is 100% a carrier function and has nothing to do with your phone; there is no setting on the phone that can prevent texts from being sent.
• Can you receive basic texts? If not, again contact Verizon; these two go together. And note that basic SMS does not require cellular data or Wi-Fi to work.

Here it gets more complicated if you have a problem with picture messages (MMS):

• FIRST, Cellular Data must be turned on to send and receive picture messages; MMS cannot use Wi-Fi
• Go to Settings/Messages and turn on the switch for MMS
• In Settings/Messages tap on send & Receive and make sure your phone number is correct and checked
• If you don’t have a switch for MMS, contact Verizon; your account is not set up correctly on their network

That’s about all I can think of without additional information from you, such as did it ever work? What other troubleshooting have you done? Is it all recipients, or only some?

I'm having the same issue but I've had it since I switched from Pixel to iphone back in February. I've worked with the phone carrier and according to them everything is fine on their end. If I try to send a picture to an android phone I get an error that says MMS messaging must be turned on, but I don't have the option to turn it on! In my messages settings I have a toggle for "Send as SMS" but there is no option for MMS.

If there is no option for MMS that means that it is not provisioned on your account, no matter what the carrier tells you. Escalate it with carrier support. And call them; carrier stores are staffed with minimally trained sales people who are generally clueless about even basic network functionality.

Are you referring to 15.0.1? Were you able to text with SMS in 15.0?

Yes, it’s T-Mobile’s fault.

Do you by chance know if they have a fix for it?

There is nothing to fix. You need to get T-Mobile to fix it.

I’m on AT&T and I’m having the same issue, so… ?
