- Important: Opening an account from outside the U.S. has a high chance of getting the account shut down.
- Network choice: The recommended option is the second one, Warp (Verizon network). It includes Caller ID and has the fastest speeds, but high-speed data may be throttled within the U.S.
- Light mode does not throttle high-speed data within the U.S.
- Dark Star mode does not support hotspot sharing outside the U.S.
- Warp and Light both support hotspot sharing outside the U.S.
[2025.9 Update] Dark Star mode now has a promotional offer with an annual fee of just $299, which is a good fit for applying from outside the U.S. The promotion ends on September 15, U.S. time.

About the US Mobile Global Data SIM
This phone plan has been around before, but the latest discount makes an already strong option even better. It almost feels wrong not to sign up. One key advantage of the US MOBILE phone plan is that it supports direct activation outside the U.S. (such as in China, Japan, and other countries). The current promotion brings the annual fee down to just $299, including:
- 20GB of high-speed international roaming data every month (the speed is better than you might expect, and the traffic routes through the U.S.)
- 200 minutes of calls per month
- 250 text messages per month
- Support for eSIM + Wi-Ficalling (can be activated remotely worldwide)
- Activate through our link and port your number within 6 months to get an extra $25
It’s very easy to use. The current promotion ends on the 28th of this month, and the full year costs just $299. Check international roaming details here:
How to Apply
- Open the application link (or scan the QR code below):
- Sign-up bonus: $25 Master gift card (you must port in within 6 months after activation, spend $100, and keep service for 6 months to qualify)
- Click Get Started.
- If you don’t have an account, sign up. If you already have one, just log in.
- After logging in, click at the bottom: Add Line→ Add a New Line
- Select the Unlimited plan
- Check the first option and continue
- Important: Do not click the two options at the top of the page, or the eSIM will not be sent directly. Just click continue at the bottom.
- For payment, you can use a supported method or enter your card number directly.
- At the bottom of the page, enter SUPER299 in the promo code field. After clicking Apply, the price will change to $299.
- Also enter my referral code in the Referral Code field: D1999DB6. You can get an additional $25 reward (you must port in within 6 months after activation, spend $100, and keep service for 6 months to qualify).
After that, the amount shown will be $299. The promotion ends on August 28, 2025.
- Just complete the payment.
Network Selection
- Click Start activation
- Select Warp (Verizon network) Caller ID
- Important: Opening Warp outside the U.S. has a high chance of getting the account shut down. If you are opening the account outside the U.S., it is recommended to choose the first option, Dark Star mode.
If you need to change networks later, just log in to your account, generate a new eSIM QR code, and replace it.
- eSIM activation: Activate eSIM
- Number setup: Port-in
- If you choose a new number, just enter a U.S. ZIP Code and the system will assign a phone number with the corresponding area code. You can choose a city number based on your preference.
- You can name the line however you want or use the default.
- During activation, you will be asked to name this phone. Enter anything you want and follow the prompts.
- Once finished, you will see the eSIM QR code, and it will also be sent to your email.
Use your iPhone camera to scan this QR code to add the eSIM. Note: you do not need to specifically use a U.S. network; a normal internet connection works fine.
The eSIM activation process can sometimes be slow, so be patient. After that, you can enable Wi-Fi calling.
Speed Test
Performance is excellent. Using Speedtest, the result in China was: 131 Mbps, arguably one of the strongest options available.
Switching Networks
Log in to your account (this requires a U.S. network; using your US Mobile phone is fine), find the line settings, and choose to switch networks. Warp (Verizon network) is recommended because it supports Caller ID.
Sign Up for US Mobile
- Open the application link (or scan the QR code below):
- Sign-up bonus: $25 Master gift card (you must port in within 6 months after activation, spend $100, and keep service for 6 months to qualify)

Summary
One of the strongest deals out there and currently among the cheapest. Go for it.
