If your Boom Mobile service just stopped working, you’re not imagining it. Boom has filed for Chapter 11 bankruptcy, and customers are losing signal. Here’s the best alternative and how to switch before you lose your number.
Why you need to switch now, not later
Here’s the part nobody tells you in the panic. Your phone number is portable, but only while your old account is active and in good standing. Once a carrier finishes winding down, porting a number out gets a lot harder. So the clock matters.
Boom has said discontinuation is on the table if its restructuring doesn’t work out, and plenty of customers are already reporting the “not registered on a network” error. If your line is dead or flickering, treat this as the moment to move. You don’t lose anything by porting out early, and you protect the number you’ve had for years.
How to pick a Boom Mobile replacement
Boom’s whole appeal was that it let you choose your network. It sold plans on Verizon, AT&T, and T-Mobile, so people picked whichever one worked best where they live. If you replace it with a carrier locked to a single network, you might end up with worse coverage than you had.
So the smart move is to look for three things:
- Network choice. Can you pick the network that already covers your area, like Boom let you?
- No contract. You’re switching under pressure. You shouldn’t get locked into anything.
- A way to test first. Coverage is personal. A free trial means you find out before you pay.
That short list is exactly why US Mobile keeps coming up for Boom refugees.
Why US Mobile is the closest match to what Boom was
US Mobile is a multi-network carrier, same idea Boom built its name on. You choose between Warp 5G, Dark Star, and Light Speed, so you’re matching your phone to the network that actually has bars where you live and work, instead of hoping one national network is good enough.
Plans start at $8/mo for light users. Unlimited Flex is $17.50/mo, Unlimited Starter is $25/mo, and Unlimited Premium is $44/mo, with annual billing knocking those down further. Every plan supports bringing your own phone, porting your number, eSIM, and there’s no contract or activation fee. If you want to see the full lineup, the US Mobile plans page lays it out.
And because coverage is the thing you actually care about right now, the free 30-day trial lets you run the network on your own phone, in your own neighborhood, before a dollar moves.

Is Boom Mobile shutting down?
Boom Mobile entered Chapter 11 bankruptcy in June 2026 and customers began losing service that month. Boom said it may discontinue service entirely if the restructuring is not successful, and that it will help customers move to another provider. Because of that, the safe move is to port your number to a new carrier while your Boom account is still active.
What is the best Boom Mobile alternative?
For most former Boom customers, US Mobile is the closest match. Like Boom, it lets you choose your network (Warp 5G, Dark Star, or Light Speed) so you can match your coverage, it has no contract, and it offers a free 30-day trial so you can test the network before switching. Plans start at $8 per month.
Can I keep my phone number when I leave Boom Mobile?
Yes, as long as your Boom account is still active and in good standing when you port out. Get your Boom account number, transfer PIN, and billing zip, then start the number transfer with your new carrier. Keep the Boom line active until the port completes, then it closes automatically.
Do I have to pay to try US Mobile?
US Mobile offers a free 30-day trial with 30GB of data on the Warp 5G or Dark Star network. You add a payment method to activate, but you are not charged during the trial, and there is no contract if you decide not to keep it. Porting a number is required to start the trial.
How fast should I switch from Boom Mobile?
Soon. Number porting depends on your old account being active, and Boom has said service could be discontinued. There is no published shutdown date, so the safest approach is to start your switch now rather than risk your line going fully dark before you port out.
