One method you can use on any type of phone is by calling the person you suspect has blocked you. While typically you can expect to hear anywhere from three to 12 rings when you call someone before going to voicemail, a blocked number will only ring once and then go straight to voicemail, according to Tom'sGuide.com.
“The simplest way to tell if you have been blocked by an Android user is to call,” Lavelle says. Just like with an iPhone, listen for it to be diverted to voicemail or play you a pre-recorded message.
First, when you try to send a text message to a phone number where you are blocked, the message can't deliver there. You don't also see the "delivered" or "sent" note. On the receiver end, the receiver won't see anything. As concerned as phone calls, the blocked call is diverted to voicemail.
You can't know for sure if someone has blocked your number on an Android without asking the person. However, if your Android's phone calls and texts to a specific person don't seem to be reaching them, your number might have been blocked.
You have your answer if their calls go through and yours doesn't. Alternatively, send a text message from a different number and wait. Messages you send from your blocked number don't appear on the recipient's phone, even though the status says it's delivered.
Android users may determine if someone has blocked their number by checking notifications. If the “sent” icon changes to “delivered,” the receiver is likely not blocked you. On the other hand, if it stays on “sent,” there's a good chance they have blocked your number.
If the notification “iMessage Sent as Text Message” only appears occasionally, it may simply be due to poor internet connectivity. However, if this happens consistently with one particular contact, there may be a chance that you have been blocked by them.
Blocked text messages disappear
When someone that you've blocked texts you, their texts go nowhere. They won't receive any notification that they're blocked, and their messages will still look like they've been sent. But you won't receive any of them, and you can't respond.
If you make a call and receive an automated message along the lines of “the customer is unavailable,” then you may have been blocked by that person's wireless carrier. The messages can vary, but the result is the same. Your call won't go through.
A red flag that you've been blocked is when you don't see the delivery status or the read receipt at all. The message you just sent will still be in a blue bubble, but it will have no delivery status below it – not even a "Not Delivered."
Basically, when you block a number on your Android or iPhone, you won't receive regular phone calls from it. That is, the calls from the blocked number will be declined automatically. On some networks, the calls are sent to Voicemail but don't worry, you won't receive voicemail notifications either.
If you see green bubbles, this means that your text messages are being sent through SMS, and they might have blocked you on iMessage. For example, if you send me a message and I receive it with a green bubble, this means that the message was sent through SMS rather than iMessage.
To check if you're blocked, try calling the person you suspect has blocked you. If the call goes straight to voicemail every time, it's possible that you've been blocked.
Texting someone who's blocked you works as you would expect. The message sends as normal, and you don't get an error message. This is no help at all for clues. If you have an iPhone and try to send an iMessage to someone who has blocked you, it will remain blue (which means it's still an iMessage).
Dial *67. This code will block your number so that your call shows up as an "Unknown" or "Private" number. Enter the code before the number that you're dialing, like so: *67-408-221-XXXX. This may work on cell phones and home phones, but it won't necessarily work on businesses.
What are Green Texts? If you text someone and the bubble that shows up is green instead of blue, you are using SMS or MMS messages. These kinds of text messages stand for “Short Messaging Service” and “Multimedia Messaging Service,” respectively.
The recipient is using a non-Apple device: If you're sending a message to an Android phone, a Windows phone, or any non-Apple device, the message will be sent as an SMS/MMS because iMessage is exclusive to Apple devices.
If you see a green message bubble instead of a blue one, then that message was sent using MMS/SMS instead of iMessage. There are several reasons for this: The person that you sent the message to doesn't have an Apple device. iMessage is turned off on your device or on your recipient's device.
If the other person switched to an Android phone, their bubble may have turned green (plus, they may have a new number). That means you may have to find it more directly if the other person switched from iOS to Android. If you were blocked, those green text bubbles mean the message was not received.
When you block a number on your Android phone, your phone won't ring when the person calls you, but the caller can still leave voicemails. The only way to prevent callers from leaving voicemails is to use an app that labels blocked numbers as spam. Your options depend on your phone carrier.
If you still receive voicemails from your blocked contacts, this is normal behavior. Blocked contacts will still be able to leave voicemails even after they are blocked. It is possible that you may be getting texts or calls not from the same number but from a number that looks very similar.
