Check your phone’s compatibility by clicking here.

Cell phones from nearly every manufacturer will work on our network as long as they are 4G VoLTE or 5G compatible and use a SIM card. If you already have a compatible phone, all you need to do is purchase an Ultra Mobile SIM kit.

If your 4G VoLTE or 5G compatible phone meets the following two criteria, your phone will work with Ultra Mobile:

Your phone requires a SIM card.

You have an unlocked phone.

If you begin your Ultra Mobile registration and your phone says, “Restricted” or “Contact Service Provider,” doesn’t allow you to make calls, or won’t grant access to your phone book, the phone is most likely locked. Contact your previous carrier to unlock your phone.

Check our 5G Coverage Map to find out if there is service in your area.

5G is the fifth generation of wireless network technology that will deliver faster download speeds and enhanced connectivity, providing us the potential to experience new, innovative technologies, and transform the way we live, work, and play.

To bring your 5G capable phone to Ultra Mobile, it must be unlocked and VoLTE compatible. To check compatibility, please visit:

You’ll access a nationwide 5G network you can rely on to keep you connected in more places. Our 5G coverage utilizes a 600MHz low band signal that reaches more cities and towns across America (based on analysis of leading 5G networks, July 2020).

We are here to help! Check your eSIM compatibility.

Dual SIM allows users to use two phone numbers at the same time. For example, you can use one number for business and another number for personal. You can have one number linked to an eSIM and one number linked to a physical SIM. eSIM-only devices, like iPhone 14, 14 Plus, 14 Pro, and 14 Pro Max allow for two eSIMs on the same device.

An eSIM is just a physical SIM that has gone digital. Instead of physically inserting a SIM into your phone to join the Ultra network, you install an eSIM onto your phone. This means you don’t have to wait for your SIM to be delivered; you can activate it straight after purchase. If you’re new to Ultra, and have an unlocked, eligible phone you can choose eSIM at the time of purchase online or at an Ultra Mobile Retailer. Please use our store locator to find one near you.

Our Care Team is here to help every day from 6 am to 6 pm PST. The easiest way to contact us is through our helpful chatbot, which can connect you to a live agent. You can also give us a call at 1-888-777-0446 or dial 611 from your Ultra Mobile phone.

Yes you can. You have up to 45 days from your plan purchase date to activate your SIM. We will notify you before we deactivate it. Should you need ore time, please call our Customer Care Team at 1-888-777-0446 or dial 611 from your Ultra Mobile phone.

The best way to see how much data you need is to log into your current provider portal and check your monthly data usage. You can go also go to your phone’s settings (Settings > Cellular Data for iPhone, or for Android Settings Menu > Data Usage > Select Dates for Android) and check that way.

-Unlimited Nationwide Talk & Text
-Unlimited Talk & Text to 90+ INTL Destinations
