You can use the Messages app on your iPhone, iPad, or iPod touch to send messages. Those messages are sent as iMessage or SMS/MMS. Learn more about the difference between the message types.
Any Apple product now will sync your messages through iCloud. Meaning, you can receive and send messages both from your phone and any Macbook. Because of Apple’s iMessage encryption, no apps are able to relay your messages to a browser and back. IMessage: An iMessage is a type of text message that can only be sent from an Apple device to another Apple device, like an iPhone or an iPad. An iMessage can include standard text like an SMS message, but also photos, videos, and other add-ons like GIFs. IMessages require an internet connection (either through Wi-Fi or a data plan) and are.
iMessage
iMessages are texts, photos, or videos that you send to another iPhone, iPad, iPod touch, or Mac over Wi-Fi or cellular-data networks. These messages are always encrypted and appear in blue text bubbles. To turn iMessage on or off, go to Settings > Messages.
SMS/MMS
If you aren’t using iMessage, you can use SMS/MMS. These messages are texts and photos that you send to other cell phones or another iPhone, iPad, or iPod touch. SMS/MMS messages aren't encrypted and appear in green text bubbles on your device.
To use SMS/MMS on an iPhone, you need a text-messaging plan. Contact your wireless carrier for more information. You can also set up your other Apple devices to send and receive messages from any Apple device.
If Wi-Fi is unavailable, iMessages will be sent over cellular data. Cellular data rates might apply.
Troubleshooting steps I would try :
- Go to Settings/Messages and make sure that Send as SMS is turned on.
- Check the recipient's contact info to make sure you are sending a message to a valid phone number.
- Go to Settings/Messages/Blocked and make sure that the person you are trying to contact is not on your block list.
- Delete your conversation with a specific number and try starting a new conversation with it.
- Restart your iPhone.
- Go to Settings/General/About and see if it prompts you to install an update from your carrier.
- Contact your carrier to make sure your text messaging plan is set up properly.
- Go to Settings/General/Reset and Reset Network Settings.
- Back up and restore your device (through iTunes or iCloud).
- Contact Apple Support.
