Sure thing! Perhaps you can't send DMs just yet because you haven't reached the member rank. I'm sure you'll reach that fast enough.
Good news is that you don't seem to be in any worse shape than a lot of others here. There's a few more people in your situation and so it seems pretty normal, nothing out of the ordinary as of now.
Few points to note:
1) Using JUMP!: I also used JUMP! online and I was worried that my order didn't go through because the site was so buggy and my order kept crashing. I do not think your order has been canceled and I do not think there was an error going through. Now, once the T-Mobile standard lines are open I suggest you give them a ring and simply ask a rep for an order status. This is the best chance of seeing if your order has not been canceled. A lot of chat reps I've spoken to aren't high enough to check details on your order (no idea why) and they'll just refer you to the number. So give them a call and then you can be sure nothing's gone wrong there.
2) Site status: Totally fine here from what I can tell, I had the exact same status.
3) First Text: Looks good, no issues there. I also received this.
4) Second Text: Normal. I got this on Monday morning I believe.
5) Third Text: Again, quite a few people received that text and so I'm going to classify it as normal. I would wait until Tuesday morning and if there's nothing then I'll give you the number and you should phone up. I say Tuesday morning (I know, seems like a long wait) because some people received the text on Friday. Seems only realistic and fair to give T-Mo a full business day or two before getting concerned (given the state T-Mo's in AND because I've received texts late at night before, 3AMish).
6) Fourth & Fifth Text: People also got this. However, a bunch of those people got shipping notifications (even delivery) today, Saturday. Point 5) applies here because they're just texts trying to get people to calm down. It's basically saying "hey, we know people ordered and we're still trying stuff."
TL;DR of it is, wait until Tuesday morning and you might have a good shot at getting some compensation (in some cases it's been a refund or upgrade of storage capacity) because you have a serious case that's hard to argue with. Calling earlier might not do much for you.
Good luck, if there's anything specific you wanted to know or something I've missed just let me know. For now though, I'm off to bed in a few!

Thank you and I agree. A bunch of people had orders canceled out of the blue. Out of all the orders though, I'd say that it's not as likely to happen as other cases. Definitely still worth giving them a call tomorrow, folks, and just confirm everything's fine. If they say it's good, perhaps you can call your bank and ask them to let all T-Mo orders through without hesitation and what-not just to be safe. Other people have done so earlier.
Also, I should note that people received devices today without being charged which is super weird. Anyhow, it can happen which is strange I guess.
