Free eSIM Trial for Android (2026)

Android phones have been eSIM-ready for years. Google kicked it off with the Pixel 2 back in 2017, and today nearly every flagship, from the Samsung Galaxy S25 to the Motorola razr+ to the Pixel 9, ships with eSIM built in. That’s a head start the iPhone only caught up to recently.

What it means for you is simple. You can activate a new carrier in minutes, no physical SIM card, nothing to wait for in the mail. US Mobile’s free eSIM trial runs right on that hardware. If you want the device-agnostic version first, here’s how the free eSIM trial works overall. This guide is the Android-specific walkthrough.

What the free eSIM trial includes on Android

Activate the trial on your Android phone and you get the full package, same as any other device:

• 30GB of premium 5G data, including 5G mmWave and C-band where available (you’re slowed down, not cut off, if you somehow burn through all 30GB)
• Unlimited talk and text across the US
• 5GB of mobile hotspot data to share with a laptop or tablet
• Instant activation over Wi-Fi, no SIM kit shipping wait
• The option to run it as a second line using dual SIM or dual eSIM, depending on your phone

Here’s the thing about Android and eSIM. Because the platform has supported it since the Pixel 2, you get more flexibility than you might expect. Use eSIM alone, pair it with a physical SIM, or run two eSIMs on the same device. The trial slots into whatever setup you already have.

One detail people miss: the trial requires you to bring (port) an existing number, and you add a card to activate. You won’t be charged during the 30-day trial, but a payment method is needed up front. If you don’t have a number to port, US Mobile runs a separate promo offer instead, so it’s worth checking the get-started flow.

Which Android phones support eSIM?

Almost every modern Android phone does. Here’s a quick breakdown by brand.

Rough rule: if your Android phone launched in 2022 or later, it almost certainly has eSIM. Some older devices do too. To check on the phone itself, open Settings and look under Network & internet or Connections. If there’s an option to add a digital SIM, you’re good. Want the deeper brand-by-brand setup detail? Our Android and Samsung eSIM guide walks through the menu paths for each maker.

How to activate the free eSIM trial on your Android phone

The first part happens on the web, then the eSIM installs through your phone’s settings. Total time is a couple of minutes.

1. Start at get-started

   Go to usmobile.com/get-started and create an account or log in.

2. Add a new line, then Special Offers

   Choose Free Trial and click Continue.

3. Pick eSIM activation

   Skip the physical Starter Kit and select eSIM so there’s nothing to wait for in the mail.

4. Add payment and check out

   You add a card to activate, but you aren’t charged during the 30-day trial. There’s no contract if you walk away.

5. Choose your network

   Select Warp or Dark Star. Paid plans give you access to all three of US Mobile’s nationwide networks, but the trial runs on these two.

6. Transfer your number

   The trial asks you to bring your existing number over. Confirm and start activation.

7. Scan the QR code on your phone

   On Pixel: Settings > Network & internet > SIMs > Add SIM. On Samsung Galaxy: Settings > Connections > SIM manager > Add eSIM. On other Androids, look for SIM Manager or Network settings. Point the camera at the QR code and confirm.

8. Turn the line on

   Toggle the new eSIM on, set it for data, and you’re connected. The line goes live in a few minutes.

If you want the generic, any-phone version of this, we cover it in our how to activate an eSIM guide. For Pixel-specific quirks, Google’s own eSIM support page is handy, and US Mobile support can help with any specific model.

Run the trial as a second line (dual SIM or dual eSIM)

Most modern Android phones hold multiple SIM profiles at once. That could be a physical SIM plus an eSIM, or two eSIMs on certain devices. It’s the safest way to test US Mobile without touching your current carrier.

1. Activate the trial

   Use the steps above to get the US Mobile eSIM installed.

2. Open SIM manager

   In Settings, find SIM manager or SIMs. Both lines show up there.

3. Label each line

   Tap each SIM and name it (say, Personal and Trial) so you don’t mix them up.

4. Set your defaults

   Choose a default SIM for calls, for texts, and for data. Customize each one however you like.

You could keep your current carrier as the default for calls and texts while using the US Mobile trial just for data. Or split everything between the two lines. Your call.

What to do after the trial

No strings attached. When the 30GB runs out or the 30 days are up, you’ve got three paths.

• Keep it and go paid. Like the network? Stay on a paid plan. They start at $8/mo for light users, $25/mo for Unlimited Starter, and annual billing drops those further. Every plan supports eSIM with no activation fee and no contract.
• Port your number over. Want US Mobile as your primary carrier? Move your existing number across. It’s free and takes about 15 minutes. The trial already proved it works for you.
• Delete and move on. Not for you? Open Settings, find SIM manager, tap the US Mobile eSIM, and delete it. Deleting the profile removes it from the phone but doesn’t bill you for anything, and you’re back to your original carrier.
