No, blue text (iMessage on Apple devices) doesn't inherently mean you're blocked; it means the message went through via the internet, but the lack of a "Delivered" status or calls going straight to voicemail, combined with messages staying blue (or sometimes switching to green), can be strong indicators. A blue bubble usually means it's an iMessage, while green means it's an SMS (carrier text). If you're blocked, messages might stay blue but never show "Delivered," or they might appear green (SMS) if the person has iMessage off, or they switched devices, or your connection is poor, making it hard to be certain without other clues like calls going to voicemail.
SMS messages that aren't delivered usually say “Message Not Delivered” underneath the green bubble. A sudden switch from blue to green could simply mean a user has their phone in airplane mode or switched to an Android device. However, when combined with other signs, it could be an indicator you've been blocked.
What are Blue Texts? Blue texts are texts, photos, or videos that you send over iMessage. These texts are sent and received over Wi-Fi or cellular data. Due to that, they won't count against your text messaging plan if you have one for your phone.
If your texts consistently show no delivery, it may be a sign you've been blocked. If your message goes through, you'll see Delivered beneath it. If it hasn't been delivered — whether due to being blocked or simply because of issues like poor reception — it will show Not Delivered.
If you've been blocked, your messages won't show a “Delivered” status or a read receipt, and you may notice the iMessage “blue-to-green” change. If your messages switch from blue (iMessage) to green (SMS), it signals that Apple's servers are no longer delivering your messages to that person's device.
You can suspect someone blocked you on an iPhone if calls go straight to voicemail (maybe after one ring) and iMessages don't show "Delivered" or "Read" receipts, but these signs can also mean their phone is off; the most reliable test is trying to call them using a different number or *67 to hide your caller ID, and if it rings normally on their end but goes to voicemail from your real number, you're likely blocked.
That's why your text bubbles are blue when you text people who also have iPhones. Blue means the message was sent as an iMessage. A green bubble with the “sent as a text message” notice indicates that your message attempted to send via iMessage but was unable to, so instead sent as a “regular” SMS or MMS.
The owner of the blocked number won't get notified, but if they try to contact you, they might see signs such as calls not going through for a long period, the SMS delivery status showing their messages as undelivered, or the status not showing at all, depending on which SMS app and phone they're using.
Apple® uses different colored message bubbles to indicate whether a message is sent via iMessage® (blue) or standard SMS/MMS (green).
Open the Messages app and click the three dots on the top right corner of the screen. From that drop-down menu, choose “Settings.” From there, tap on “Block numbers and messages.” From there, go to “Blocked messages.” From there, all of your blocked text threads will be there.
Muting helps you ignore someone without preventing them from doing anything. Blocking someone prevents them from messaging you, commenting on your observations, identifying your observations, and otherwise interacting with you on iNaturalist.
Messages that are sent or received won't be delivered. Also, the contact won't get a notification that the call or message was blocked.
While you can still send messages and they'll appear as blue bubbles in your conversation, they won't actually reach the recipient. The messages won't show "Delivered" or "Read" status badges, and the person who blocked you won't receive any notification of your attempts to contact them.
iMessages appear in blue text bubbles on your device. When you use iMessage, your conversations are encrypted end-to-end, so they can't be read while they're sent between devices. To turn iMessage on or off, go to Settings > Apps > Messages. If Wi-Fi is unavailable, iMessages will be sent over cellular data.
On an iPhone, a green text bubble means your message was sent as a standard SMS instead of an iMessage. While messages you send appearing in green could mean you've been blocked, it could also mean the recipient has iMessage turned off, they've switched to an Android device, or there's a network issue.
You can suspect someone blocked you on an iPhone if calls go straight to voicemail (maybe after one ring) and iMessages don't show "Delivered" or "Read" receipts, but these signs can also mean their phone is off; the most reliable test is trying to call them using a different number or *67 to hide your caller ID, and if it rings normally on their end but goes to voicemail from your real number, you're likely blocked.
A sign of a blocked number will usually be if you don't receive a delivered or read notification when sending a message. There is no way around a blocked number unless the recipient decides to unblock you. As a best practice, always make sure you only message phone numbers designated to receive your text messages.
However, the big distinction is that, unlike with a Block, Ignore will still let them see your profile and activity and allow them to send you messages (which you won't know about unless you unhide them).
Check the chat bubble color
This is only true if both of you use iMessage on iPhones. This isn't a foolproof method. You may see a green bubble in the following situations: If the other person switched to an Android phone, their bubble may have turned green.
