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.

Our high-speed data will always attempt 5G • 4G LTE speeds, but certain locations or network conditions will render 5G • 4G LTE unavailable. Your network speed will be dependent on your location, coverage and device.
After the allotted 5G • 4G LTE data is exhausted, data speeds will be slowed. Further throttling may occur for heavy data users. For any questions about data speed

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.

5G isn’t replacing 4G any time soon. In fact, they will coexist and work together. 5G-capable phones can use both 4G and 5G technology.

5G is already available on Ultra Mobile to anyone with an Ultra plan and a 5G-capable phone to access our 5G network. 5G coverage varies nationwide and may not be available in your area.

5G simply increases the speed that you can download files. If a file requires 2MB of data to download it on 4G, it will still be 2MB of data to download it on 5G. You may just finish downloading it faster.

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

Yes. You can use the mobile hotspot on your 5G smartphones the same way you do with LTE. Hotspot usage draws from your monthly data allotment.

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).

A 5G indicator will appear when a 5G capable device is within range of a 5G signal, even if the device is not in use.

Unfortunately, Ultra plans do not support smartwatches right now.
