iMessage is great for messaging other Apple device users, but what if the service isn’t available sometimes, and you need to reach someone?
In such cases, you can quickly send a regular SMS text message instead. We’ll teach you how to send texts as SMS messages on your iPhone.

1. Manually Send Messages as SMS
you’re able to manually sendgreen bubbles instead of blue bubbles on your iPhone, even without turning off your cellular data and Wi-Fi. It’s pretty straightforward, and here’s how to do it:
If you tap and hold the message bubble and seeSend to Email AddressinsteadofSend as Text Message, it’s likely because there’s no phone number attached to the contact you’re messaging. Instead, only an email address is associated with their contact information, which you can’t send an SMS to.

2. Automatically Send Messages as SMS
To automatically send messages as SMS on your iPhone, you can message someone who doesn’t use an Apple device or someone who has disabled iMessage. Or, you can completelydisable iMessage on your device. There’s another alternative, which is to tweak your settings. Here’s how:
Your messages should automatically send as SMS whenever iMessage is unavailable. If you want to send messages automatically as SMS when iMessage is available, disable Wi-Fi and cellular data first.

Send an SMS When iMessage Is Unavailable
If you’re worried about reaching people when iMessage is unavailable, or you’d simply prefer to send a regular text message, there are ways around it. You can manually send messages from your iPhone as SMS, or you can send them as SMS automatically when iMessage is unavailable.
If you’d prefer something a little more drastic, turn off iMessage to ensure your messages always send as SMS messages.
