What is the expected increase in EBITDA for the next four quarters and how much of it is due to promotions
ut content goes to the Internet. Internet goes to mobile. It seems like there's an appending now that say mobile goes to cloud.
Can you talk a little bit about what 5G network slicing might mean? And can you maybe allude to what you guys see as the opportunity? Is mobile headed to the cloud?
Mike Sievert -- President and Chief Executive Officer
Well, first of all, Rick, I'm so flattered that you are quoting us on that. That makes -- that's awesome. Look, the people are asking what are some of the use cases that will fuel 5G, especially as it relates to enterprise, but you could also say with consumer. And of course, it's cloud.
And this notion that enterprises don't want to be buying and deploying assets. They want to have Networking as a Service. They want to have Computing as a Service. And that does raise very interesting prospects for our business as it relates to being able to ultimately serve enterprise customers with Networking as a Service.
But even putting that aside, which is a fascinating area that our business model will -- it doesn't rely on yet but that we won't be left behind on. The other issue is that customers, both consumers and businesses alike, as they rely on cloud are going to need very high-speed, low-latency network for that experience to be good. The more local your compute is, the less your network matters. And the more cloud your compute is, the more your network matters.
And people are asking, will T-Mobile's 5G advantage matter as it relates to choice? Or will it be an advantage that customers don't care about or notice? Well, cloud is a differentiator there because the more enterprise customers and consumer applications rely on cloud, the more our network shines. And it really showcases a potential again tailwind for the future.

Great. Thanks Mike.

You bet.

Colby Synesael -- Cowen and Company
Gerat. Thank you. I think there's an expectation that competition is going to increase, and I think we all think about that fairly generically when we say that. But that's expected in the second half of the year tied to this expectation that switching is going to improve, which you've also are expecting.
I'm just curious what you baked into your EBITDA guidance in terms of flexibility to respond to that competition to the extent it does show itself and it is aggressive. And then secondly, just a point of clarification. You guys mentioned that you expect ARPU to be up in 2Q through 4Q versus the results in 1Q. I'm just wondering if that's linear.
In other words, 2Q obviously up over 1Q but is 3Q higher than 2Q and so forth? Thank you.
Mike Sievert -- President and Chief Executive Officer
Well, Colby, first of all, thanks for the question. It's awesome. You're our last question of the day. Those are great questions.
And if you have your pen out, we'll just give you the ARPU figures for the next four quarters.
Colby Synesael -- Cowen and Company
That would be awesome.
Mike Sievert -- President and Chief Executive Officer
We're going to start with ARPU because it's a great question, and then I'll come back to the competition piece. So Peter?
Peter Osvaldik -- Chief Financial Officer
All right. Certainly. And also how much we baked into EBITDA for promos by quarter. I think all of that would be great.
No, they're excellent questions. No, it's not necessarily linear. There's obviously seasonality. There's promotional aspects.
There's other things. There's when investments come, how much of a mix from T-Mobile for business or consumer. But it is low watermark in Q1, and the rest of the year will be higher than that but not necessarily linearly increasing.
Mike Sievert -- President and Chief Executive Officer
And to your other question, it really goes to our whole philosophy and mentality. Some people who follow us closely, if you look at our track record on guidance and then our actuals, would be forgiven for saying we're conservative if you look at our actuals a
