Looking for a stream of tonight’s Eastern Conference Finals Game 3 (8:30 p.m. ET on TNT) between the Cleveland Cavaliers and Boston Celtics that doesn’t require a cable log-in? If you’re in the United States, you can watch the game through Sling TV or DirecTV Now, online streaming services that provide access to select channels, including TNT.

Here’s how you can watch for free, and what you need to know in order to navigate each service:

Launch a Free Trial With Sling TV or DirecTV Now

Sling and DirecTV Now have monthly fees ranging from $20 to $70 depending on the package you’ve selected. But both services provide a free seven-day trial, so you can watch the game for free on your computer, mobile device or connected TV through either service. You can click here to sign up for Sling TV and click here to sign up for DirecTV Now. Both services will prompt you to download a mobile app if you’re on a mobile device. If you’re on a desktop or laptop computer, you’ll be promoted to download the Sling desktop app if you sign up for Sling. If you sign up for DirecTV Now, you’ll be able to watch programming right in your Internet browser.

The services are extremely similar, and if your main concern is watching today’s game for free, either will do the trick. If you’re interested in keeping the service after the seven-day trial ends, there are some slight differences worth considering. Which service is best for you depends largely on how many channels you’re looking for and how much money you’re willing to spend.

Here’s a look at what each service has to offer:

Least Expensive Way to Watch NBA Broadcasts on TNT & ESPN: Sling TV

Both Sling and DirecTV Now offer a free seven-day trial, so you can watch tonight’s game for free through either service. But if after the trial ends, you’re interested in access to NBA games on TNT and ESPN but don’t need a whole lot else, Sling is your best option.

Sling’s Orange package, which includes both TNT and ESPN, costs only $20 per month. That’s $15 per month less than DirecTV Now’s Live a Little package, which includes more than 60 channels, but costs $35 per month. Sling’s Blue package, which costs $25 per month, also includes TNT, so you can watch today’s game through either package. You can also sign up for both packages at a discounted rate of $40 per month after the trial ends.

If you’re a big NBA, NHL or college sports fan, you might want to consider adding the Sports Extra add-on, which costs an additional $10 per month and includes NBA TV, NHL Network, SEC Network, Pac 12 Network and ESPNU, among other channels. Going with Sling Orange and the Sports Extra add-on would put your monthly bill at $30 — still a tad more affordable than the aforementioned DirecTV Now Live a Little package.

You can click here here to sign up for Sling and launch the free trial. You’ll need to enter your credit card information when signing up, but if you cancel the subscription before the trial ends, you won’t be charged. If your’e on a desktop of laptop computer, you’ll be prompted to download the Sling desktop app once you sign up. If you’re on a mobile device, you’ll also be prompted to download the app upon signing up.

You can also click here to download the Sling app in the iTunes App Store.

You can click here to download the Sling app in the Google Play Store.

There’s also a Sling app for Roku, Chromecast, Nexus player, ZTE and XBox One. Click here for a full list of compatible devices. If you’re looking to access Sling programming on a connected TV, follow the steps listed above to create an account, then enter your log-in information when launching the app on your connected TV.

Most Available Regional Sports Programming: Sling TV

Another advantage for Sling is the level of access it provides to regional sports programming. Though both Sling and DirecTV Now offer Fox Sports’ stable of regional sports networks, along with the YES Network in the New York market, Sling is the only one of the two services that will soon be offering Comcast Sportsnet’s regional networks, which have broadcast rights to a bevy of MLB, NBA and NHL teams, including the defending World Series champion Cubs in the Chicago market.

CSN has primary broadcasting rights to the following teams:

• Boston Celtics
• Chicago Blackhawks
• Chicago Bulls
• Chicago Cubs
• Chicago White Sox
• Golden State Warriors
• Oakland Athletics
• Philadelphia 76ers
• Philadelphia Flyers
• Philadelphia Phillies
• Portland Trail Blazers
• Sacramento Kings
• San Francisco Giants
• San Jose Sharks
• Washington Capitals
• Washington Wizards

Both the CSN networks and the Fox Sports networks are available in Sling’s blue package, which costs $25 per month. If you’re interested in both CSN and ESPN programming, we recommend selecting the Orange + Blue bundle, which gives you access to both packages for a total of $40.

More Channels, a Simpler Desktop Experience & Data Preservation for AT&T Customers: DirecTV Now

Among the advantages DirecTV Now has is the ability to watch content right in your Internet browser on a desktop or laptop computer without needing to download an app. Sling, by contrast, requires you to take the extra step of downloading a desktop app. (Both services require you to download an app to watch programming on a mobile device.)

Another advantage: If you have diverse programming needs that go beyond sports, and you’re willing to pay more for more channels, DirecTV Now’s Go Big package includes more than 100 channels and costs $60 per month after the free trial, while the Gotta Have It package costs $70 per month after the free trial but includes more than 120 channels.

Among the sports-centric channels available through DirecTV Now but not Sling are MLB Network and Big Ten Network. You can click here to check out DirecTV Now’s various channel lineups.

Lastly: If you’re an AT&T wireless customer, you can stream content on your phone anywhere on the AT&T network without using up data.

You can click here to sign up for DirecTV Now and launch a free trial. You’ll need to enter your credit card information when signing up, but if you cancel the subscription before the trial ends, you won’t be charged.

You can click here to download the app from the iTunes App Store.

You can click here to download the app from the Google Play Store.

You can also watch on a connected TV through Amazon Fire TV, Amazon Fire Stick TV, Apple TV or Chromecast. Click here for a full list of compatible devices.

The app is not yet available for Chromecast, Roku or XBox One.

Recap: Similar Services, Both With a Free Trial

To recap: If you’re just looking to watch tonight’s game, either service will give you what you’re looking for, and your viewing experience will be virtually the same, regardless of which service you choose, and on which device you’re watching.

If you’re interested in keeping one of the two services beyond the game, the differences are mostly a matter of personal preferences and personal circumstances. For instance, if you live in a region where your favorite MLB or NBA team’s games are on a Comcast network, the ability to watch those games may put Sling over the top.

If you don’t have a CSN in your area, or if it’s not important for you to have it, you may find DirecTV Now’s more expansive programming options appealing. Either way, if you’re unsure which service you’d prefer, we recommend launching a free trial for both, and seeing which you like better. You can launch the Sling free trial here and the DirecTV Now free trial here.
