Google hangouts unblocked6/7/2023 That way you can still protect the Users who don't know any better without degrading the service of those who do.Īnyways, for now, for anyone who runs into this same issue, try sending your messages as MMS instead and see if they get delivered, if your issue is similar to mine, they will be. I think its a good thing that AT&T wants to protect their users, but if you are going to cast such a wide net like this, at least give your Paying Customers a way to whitelist numbers they would like to receive messages from. It would be nice if AT&T gave their users a way to White List Numbers that they do not want blocked, that would make this so much simpler. I could understand if the sites were traced back to something Malicious, but in my case these are all Corporate Domains I am texting, nothing nefarious, yet AT&T Still blocks me over it. The weird part is that they don't appear to warn anyone anywhere not to send Links with Port Numbers. I just spent the better part of the last 2 days testing this theory, and I am certain AT&T is doing something to filter out these messages. I know this is an AT&T Issue because Every single other Carrier this does not happen with. This also works with normal links, although its not as consistent with normal links without a Port number, it seems like if it doesn't have a port number you have to send a lot more messages with links before they block that Google Voice Number. So then I go through the trouble of Getting a new Number issued to my Google account, and then magically I can text all those wonderful AT&T Subscribed Clients again, until that magical day where I need to send out a New VPN Domain to connect to. That is obviously just an example, but whenever I send out Links just like that from my Google Voice Number, a lot of the times the AT&T Customer DOES NOT receive that particular text, and then If I send a text Containing that same Link, or a similar one 2 more times to the same number, that Google Voice Number becomes Blocked for good, and now I can not SMS Message any of my AT&T Customers from that point on. So I noticed what will get my Number blocked EVERY SINGLE TIME is sending something along the lines of ":5566". A lot of time this is done over email, or some other method, but every now and again you have someone who just wants to text, and that is usually not an issue for me. I am IT Support for a number of Clients across the Western United States, and that means from time to time, especially when configuring new VPN's for clients, I am texting them IP's to connect to. Specifically, links with a Port Number at the end. In my case, what caused the Blocking was sending links. I am actually an AT&T User myself, so I was able to text myself a bunch from my various Google Voice Numbers to find out exactly what was causing the blocking, and then verified that I was indeed blocked by texting various Clients that I have that use AT&T What is weird, at least in my case with every new number I tested, even after SMS was blocked, if you message these same people with MMS, it works and goes through. Furthermore, threw a bit of testing and throwing away google Voice numbers, I have figured out what causes AT&T To Block the Texts.
