US Mobile Current Deals (New iPhone 18 Trade-In Deal, $30 Referral Credit)

Posted on September 22, 2026 // 10 Comments

Updated with new promo details. US Mobile is an MVNO offering service from all three major networks, Verizon (Warp), AT&T (Dark Star), and T-Mobile (Light Speed). I wrote previously about balancing saving money on MVNOs with high data speed priority, and their “Unlimited Premium” plan on Warp (Verizon) was my personal choice. Since then, US Mobile has been recognized as #1 rated by both Wirecutter (NYT) and Consumer Reports. I’ve also expanded to three different phone lines and two Apple Watch standalone plans (for the kids).

Here are some links to help you find the best current promo.

  • New Trade-In Deal + $100 credit for iPhone 18 Pro/Pro Max. Instead of trading in your old phone to Apple, US Mobile will pay you more for your trade-in. See chart in link. Then, if you activate an iPhone 18 Pro/Pro Max (bought elsewhere) at US Mobile, they will give you an instant $100 off on new lines. On existing lines, they will give their Multi-Network feature free for 12 months (lets you switch between Verizon and AT&T, for example).
  • US Mobile Promo Archive. This page is very handy as it not only shows the various current promos, but also saves the old promos for your future reference.
  • Current US Mobile Plan Promos. This is their generic plans landing page, and for a while they have been offering the first year of Unlimited Premium for $299 a year and Unlimited Starter for $199 a year.
  • Additional $30 prepaid card if you use my referral link during signing up for a new line. Stacks with the promos above. See details below.

Reasons why I chose their Annual Unlimited Premium plan on Warp (Verizon), switching from Mint Mobile:

  • The Unlimited Premium plan comes with 5G Priority data level QCI 8 with Verizon, which is equal in priority to the official Verizon postpaid plans. I just went to another crowded event and having high data priority made life easier. Plus, with Premium the “Unlimited Data” actually means unlimited. No speed throttling after 30 GB or 50 GB, for example. 50 GB Hotspot bucket is useful for WiFi while in cafes/traveling in US. When traveling internationally, you 20 GB data, 200 mins, 250 texts in 125+ countries.
  • The initial year can be very cheap, usually around $300 for the first year upfront on their top-tier Unlimited Premium, which works out to about $25 a month. Renewal is $390/year. After the first year, I can downgrade to a cheaper plan, but I will probably stay because…
  • The Warp network comes with a free smartwatch plan, so I can use my Apple Watch cellular without paying the usual $5 to $10 extra per month with other carriers. I like to swim/run/exercise with just a watch, and my previous provider Mint Mobile and many other MVNOs don’t support smartwatches at all.

$30 referral credit details. You can stack the current promo with my referral link to get an $30 referral credit. Click on my referral link first, which should auto-fill the promo code 0360B9DC before checking out. You will get sent a $30 virtual prepaid card after porting-in at least 1 line on an Unlimited or By the Gig Plan. You no longer have to wait 6 months.

    Did you happen to find a way to apply this to your kids existing watch plan? I played around with different options and no luck

      While the offer is available to existing customers, it also says on the first year only. But if you add a new Apple Watch on a new line, it should work (up to 3 new plans). Here is the fine print:

      1. A maximum of 3 Smartwatch plans per account can get the discounted pricing.
      2. To receive the discounted price on a Smartwatch Standalone or Companion Plan purchase, users must enter the promo code WARPWATCH at checkout. It is for both new line activations and port ins.
      3. The promo code will reduce the price of the annual Watch plans to $39/year for 12 months. After that period, the discount will end, and the line will be charged $78/year.

    There is a new, similar sale going on now through 2/25/26 – and it’s $100 off instead of $90. Code 100OFF Promo and works on all networks.

    Hi Jonathan,
    Given I see you have used BetterRoaming before and now USMobile, do you know how to Port-Out (transfer) a phone number from BetterRoaming to USMobile? For USMobile to port-in an existing cell number, it needs both an Account Number and a Transfer PIN, neither of which seem to be obviously provided or communicated by BetterRoaming. Any tips or suggestions?

      I personally cancelled my BetterRoaming plan and got rid of the number because it was fixed area code (not local), and signed up fresh with US Mobile with an area code of my choosing (local). Otherwise, you’ll probably have to contact BetterRoaming for the porting info.

        For anyone wondering about the answer to this in the future: The process to port-out your phone number from BetterRoaming to another provider (such as USMobile) is that first of all, through BetterRoaming’s website submit a support request to initiate the phone number port-out and ask for a PIN number. Within 24 hours, BetterRoaming will reply back with a PIN, and then you can tell USMobile that PIN (plus your phone number as the account number) so that they can port-in the phone number. The process seems to take far longer than it would with the major carriers, but it worked.

    Thanks for the update. I have had Mint mobile for years. Does this promo of $199 and $299 end this month. My Mint renews 11/1.
    Is your referral still good?
    Thanks

      I can’t be sure when the promo will end, but they have been pushing back the expiration date for over a year now, so my guess is that it will still be around. I think they just keep the expiration dates soon to encourage folks to sign up and not wait. They just updated the referral program, I just updated the info, so yes I think that should still work as well. Thanks for reading!

      I agree, the tough thing with Mint Mobile is that you only have the chance to renew once a year, and if you wait until the last moment you have the pressure to simply renew for another year. So I recommend switching over a little before, like a week before, so you don’t feel the pressure. These days it’s mostly eSIM so the transfer is quite fast and US Mobile has a good live chat feature that helps you through it if there are any issues.
